FIELD OF THE INVENTION
[0002] Described herein are compounds, pharmaceutical compositions
and medicaments that include such compounds, and methods of using
such compounds to modulate store operated calcium (SOC) channel
activity.
BACKGROUND OF THE INVENTION
[0003] Calcium plays a vital role in cell function and survival.
For example, calcium is a key element in the transduction of
signals into and within cells. Cellular responses to growth
factors, neurotransmitters, hormones and a variety of other signal
molecules are initiated through calcium-dependent processes.
[0004] Virtually all cell types depend in some manner upon the
generation of cytoplasmic Ca.sup.2+ signals to regulate cell
function, or to trigger specific responses. Cytosolic Ca.sup.2+
signals control a wide array of cellular functions ranging from
short-term responses such as contraction and secretion to
longer-term regulation of cell growth and proliferation. Usually,
these signals involve some combination of release of Ca.sup.2+ from
intracellular stores, such as the endoplasmic reticulum (ER), and
influx of Ca.sup.2+ across the plasma membrane. In one example,
cell activation begins with an agonist binding to a surface
membrane receptor, which is coupled to phospholipase C (PLC)
through a G-protein mechanism. PLC activation leads to the
production of inositol 1,4,5-triphosphate (IP.sub.3), which in turn
activates the IP.sub.3 receptor causing release of Ca.sup.2+ from
the ER. The fall in ER Ca.sup.2+ then signals to activate plasma
membrane store-operated calcium (SOC) channels.
[0005] Store-operated calcium (SOC) influx is a process in cellular
physiology that controls such diverse functions such as, but not
limited to, refilling of intracellular Ca.sup.2+ stores (Putney et
al. Cell, 75, 199-201, 1993), activation of enzymatic activity
(Fagan et al., J. Biol. Chem. 275:26530-26537, 2000), gene
transcription (Lewis, Annu. Rev. Immunol. 19:497-521, 2001), cell
proliferation (Nunez et al., J. Physiol. 571.1, 57-73, 2006), and
release of cytokines (Winslow et al., Curr. Opin. Immunol.
15:299-307, 2003). In some nonexcitable cells, e.g., blood cells,
immune cells, hematopoietic cells, T lymphocytes and mast cells,
SOC influx occurs through calcium release-activated calcium (CRAC)
channels, a type of SOC channel.
[0006] The calcium influx mechanism has been referred to as
store-operated calcium entry (SOCE). Stromal interaction molecule
(STIM) proteins are an essential component of SOC channel function,
serving as the sensors for detecting the depletion of calcium from
intracellular stores and for activating SOC channels.

BRIEF DESCRIPTION OF THE FIGURES
[0120] FIG. 1 outlines the I.sub.CRAC channel pathway.
[0121] FIG. 2 shows the typical I.sub.CRAC traces in cells stably
overexpressing human Orai1 and STIM 1 in response to the voltage

activated, and at 5 min after I.sub.CRAC is fully activated by
depletion of intracellular calcium stores.
DETAILED DESCRIPTION
[0122] Cellular calcium homeostasis is a result of the summation of
regulatory systems involved in the control of intracellular calcium
levels and movements. Cellular calcium homeostasis is achieved, at
least in part, by calcium binding and by movement of calcium into
and out of the cell across the plasma membrane and within the cell
by movement of calcium across membranes of intracellular organelles
including, for example, the endoplasmic reticulum, sarcoplasmic
reticulum, mitochondria and endocytic organelles including
endosomes and lysosomes.
[0123] Movement of calcium across cellular membranes is carried out
by specialized proteins. For example, calcium from the
extracellular space can enter the cell through various calcium
channels and a sodium/calcium exchanger and is actively extruded
from the cell by calcium pumps and sodium/calcium exchangers.
Calcium can also be released from internal stores through inositol
trisphosphate or ryanodine receptors and can be taken up by these
organelles by means of calcium pumps.
[0124] Calcium can enter cells by any of several general classes of
channels, including but not limited to, voltage-operated calcium
(VOC) channels, store-operated calcium (SOC) channels, and
sodium/calcium exchangers operating in reverse mode. VOC channels
are activated by membrane depolarization and are found in excitable
cells like nerve and muscle and are for the most part not found in
nonexcitable cells. Under some conditions, Ca.sup.2+ can enter
cells via Na.sup.+--Ca.sup.2+ exchangers operating in reverse
mode.
[0125] Endocytosis provides another process by which cells can take
up calcium from the extracellular medium through endosomes. In
addition, some cells, e.g., exocrine cells, can release calcium via
exocytosis.
[0126] Cytosolic calcium concentration is tightly regulated with
resting levels usually estimated at approximately 0.1 .mu.M in
mammalian cells, whereas the extracellular calcium concentration is
typically about 2 mM. This tight regulation facilitates
transduction of signals into and within cells through transient
calcium flux across the plasma membrane and membranes of
intracellular organelles. There is a multiplicity of intracellular
calcium transport and buffer systems in cells that serve to shape
intracellular calcium signals and maintain the low resting
cytoplasmic calcium concentration. In cells at rest, the principal
components involved in maintaining basal calcium levels are calcium
pumps and leak pathways in both the endoplasmic reticulum and
plasma membrane. Disturbance of resting cytosolic calcium levels
can affect transmission of calcium-dependent signals and give rise
to defects in a number of cellular processes. For example, cell
proliferation involves a prolonged calcium signaling sequence.
Other cellular processes that involve calcium signaling include,
but are not limited to, secretion, transcription factor signaling,
and fertilization.
[0127] Cell-surface receptors that activate phospholipase C (PLC)
create cytosolic Ca.sup.2+ signals from intra- and extra-cellular
sources. An initial transient rise of [Ca.sup.2+].sub.i
(intracellular calcium concentration) results from the release of
Ca.sup.2+ from the endoplasmic reticulum (ER), which is triggered
by the PLC product, inositol-1,4,5-trisphosphate (IP.sub.3),
opening IP.sub.3 receptors in the ER (Streb et al. Nature, 306,
67-69, 1983). A subsequent phase of sustained Ca.sup.2+ entry
across the plasma membrane then ensues, through specialized store
operated calcium (SOC) channels (in the case of immune cells the
SOC channels are calcium release-activated calcium (CRAC) channels)
in the plasma membrane. Store-operated Ca.sup.2+ entry (SOCE) is
the process in which the emptying of Ca.sup.2+ stores itself
activates Ca.sup.2+ channels in the plasma membrane to help refill
the stores (Putney, Cell Calcium, 7, 1-12, 1986; Parekh et al.,
Physiol. Rev. 757-810; 2005). SOCE does more than simply provide
Ca.sup.2+ for refilling stores, but can itself generate sustained
Ca.sup.2+ signals that control such essential functions as gene
expression, cell metabolism and exocytosis (Parekh and Putney,
Physiol. Rev. 85, 757-810 (2005).
[0128] In lymphocytes and mast cells, activation of antigen or Fc
receptors, respectively causes the release of Ca.sup.2+ from
intracellular stores, which in turn leads to Ca.sup.2+ influx
through CRAC channels in the plasma membrane. The subsequent rise
in intracellular Ca.sup.2+ activates calcineurin, a phosphatase
that regulates the transcription factor NFAT. In resting cells,
NFAT is phosphorylated and resides in the cytoplasm, but when
dephosphorylated by calcineurin, NFAT translocates to the nucleus
and activates different genetic programmes depending on stimulation
conditions and cell type. In response to infections and during
transplant rejection, NFAT partners with the transcription factor
AP-1 (Fos-Jun) in the nucleus of "effector" T cells, thereby
transactivating cytokine genes, genes that regulate T cell
proliferation and other genes that orchestrate an active immune
response (Rao et al., Annu Rev Immunol., 1997; 15:707-47). In
contrast, in T cells recognizing self antigens, NFAT is activated
in the absence of AP-1, and activates a transcriptional programme
known as "anergy" that suppresses autoimmune responses (Macian et
al., Transcriptional mechanisms underlying lymphocyte tolerance.
Cell. 2002 Jun. 14; 109(6):719-31). In a subclass of T cells known
as regulatory T cells which suppress autoimmunity mediated by
self-reactive effector T cells, NFAT partners with the
transcription factor FOXP3 to activate genes responsible for
suppressor function (Wu et al., Cell, 2006 Jul. 28; 126(2):375-87;
Rudensky A Y, Gavin M, Zheng Y. Cell. 2006 Jul. 28;
126(2):253-256).
[0129] The endoplasmic reticulum (ER) carries out a variety
processes. The ER has a role as both a Ca.sup.2+ sink and an
agonist-sensitive Ca.sup.2+ store and, protein folding/processing
takes place within its lumen. In the latter case, numerous
Ca.sup.2+-dependent chaperone proteins ensure that newly
synthesized proteins are folded correctly and sent off to their
appropriate destination. The ER is also involved in vesicle
trafficking, release of stress signals, regulation of cholesterol
metabolism, and apoptosis. Many of these processes require
intraluminal Ca.sup.2+, and protein misfolding, ER stress
responses, and apoptosis can all be induced by depleting the ER of
Ca.sup.2+ for prolonged periods of time. Because it contains a
finite amount of Ca.sup.2+, it is clear that ER Ca.sup.2+ content
must fall after release of that Ca.sup.2+ during stimulation.
However, to preserve the functional integrity of the ER, it is
vital that the Ca.sup.2+ content does not fall too low or is
maintained at least at a low level. Replenishment of the ER with
Ca.sup.2+ is therefore a central process to all eukaryotic cells.
Because a fall in ER Ca.sup.2+ content activates store-operated
Ca.sup.2+ channels in the plasma membrane, a major function of this
Ca.sup.2+ entry pathway is believed to be maintenance of ER
Ca.sup.2+ levels that are necessary for proper protein synthesis
and folding. However, store-operated Ca.sup.2+ channels have other
important roles.
[0130] The understanding of store operated calcium entry was
provided by electrophysiological studies which established that the
process of emptying the stores activated a Ca.sup.2+ current in
mast cells called Ca.sup.2+ release-activated Ca.sup.2+ current or
I.sub.CRAC. I.sub.CRAC is non-voltage activated, inwardly
rectifying, and remarkably selective for Ca.sup.2+. It is found in
several cell types mainly of hemapoietic origin. I.sub.CRAC is not
the only store-operated current, and it is now apparent that
store-operated influx encompasses a family of Ca.sup.2+-permeable
channels, with different properties in different cell types.
I.sub.CRAC was the first store-operated Ca.sup.2+ current to be
described and remains a popular model for studying store-operated
influx.
[0131] Store-operated calcium channels can be activated by any
procedure that empties ER Ca.sup.2+ stores; it does not seem to
matter how the stores are emptied, the net effect is activation of
store-operated Ca.sup.2+ entry. Physiologically, store emptying is
evoked by an increase in the levels of IP.sub.3 or other
Ca.sup.2+-releasing signals followed by Ca.sup.2+ release from the
stores. But there are several other methods for emptying stores.
These methods include the following:
1) elevation of IP.sub.3 in the cytosol (following receptor
stimulation or, dialyzing the cytosol with IP.sub.3 itself or
related congeners like the nonmetabolizable analog
Ins(2,4,5)P.sub.3); 2) application of a Ca.sup.2+ ionophore (e.g.,
ionomycin) to permeabilize the ER membrane; 3) dialyzing the
cytoplasm with high concentrations of Ca.sup.2+ chelators (e.g.,
EGTA or BAPTA), which chelate Ca.sup.2+ that leaks from the stores
and hence prevent store refilling; 4) exposure to the
sarcoplasmic/endoplasmic reticulum Ca.sup.2+-ATPase (SERCA)
inhibitors like thapsigargin, cyclopiazonic acid, and
di-tert-butylhydroquinone; 5) sensitizing the IP.sub.3 receptors to
resting levels of InsP.sub.3 with agents like thimerosal; and 6)
loading membrane-permeable metal Ca.sup.2+ chelators like
N,N,N',N'-tetrakis(2-pyridylmethyl)ethylene diamine (TPEN) directly
into the stores.
[0132] Through mass action, TPEN lowers free intraluminal Ca.sup.2+
concentration without changing total store Ca.sup.2+ such that the
store depletion-dependent signal is generated.
[0133] These methods of emptying stores are not devoid of potential
problems. The key feature of store-operated Ca.sup.2+ entry is that
it is the fall in Ca.sup.2+ content within the stores and not the
subsequent rise in cytoplasmic Ca.sup.2+ concentration that
activates the channels. However, ionomycin and SERCA pump blockers
generally cause a rise in cytoplasmic Ca.sup.2+ concentration as a
consequence of store depletion, and such a rise in Ca.sup.2+ could
open Ca.sup.2+-activated cation channels permeable to Ca.sup.2+.
One way to avoid such problems is to use agents under conditions
where cytoplasmic Ca.sup.2+ has been strongly buffered with high
concentrations of Ca.sup.2+ chelator such as EGTA or BAPTA.
Store-Operated Calcium Entry
[0134] Reduced calcium concentration in intracellular calcium
stores such as the endoplasmic reticulum resulting from release of
calcium there from provides a signal for influx of calcium from the
extracellular medium into the cell. This influx of calcium, which
produces a sustained "plateau" elevation of cytosolic calcium
concentration, generally does not rely on voltage-gated plasma
membrane channels and does not involve activation of calcium
channels by calcium. This calcium influx mechanism is referred to
as capacitative calcium entry (CCE), calcium release-activated,
store-operated or depletion-operated calcium entry. Store-operated
calcium entry can be recorded as an ionic current with distinctive
properties. This current is referred to as I.sub.SOC
(store-operated current) or I.sub.CRAC (calcium release-activated
current).
[0135] Electrophysiological analysis of store-operated or calcium
release-activated currents reveal distinct biophysical properties
(see, e.g., Parekh and Penner (1997) Physiol. Rev. 77:901-930) of
these currents. For example, the current can be activated by
depletion of intracellular calcium stores (e.g., by
non-physiological activators such as thapsigargin, CPA, ionomycin
and BAPTA, and physiological activators such as IP.sub.3) and can
be selective for divalent cations, such as calcium, over monovalent
ions in physiological solutions or conditions, can be influenced by
changes in cytosolic calcium levels, and can show altered
selectivity and conductivity in the presence of low extracellular
concentrations of divalent cations. The current may also be blocked
or enhanced by 2-APB (depending on concentration) and blocked by
SKF96365 and Gd.sup.3+ and generally can be described as a calcium
current that is not strictly voltage-gated.
[0136] Patch-clamp studies in mast cells and Jurkat leukemic T
cells have established the CRAC entry mechanism as an ion channel
with distinctive biophysical characteristics, including a high
selectivity for Ca.sup.2+ paired with an exceedingly low
conductance. Furthermore, the CRAC channel was shown to fulfill the
rigorous criteria for being store-operated, which is the activation
solely by the reduction of Ca.sup.2+ in the ER rather than by
cytosolic Ca.sup.2+ or other messengers generated by PLC (Prakriya
et al., In Molecular and Cellular Insights into Ion Channel Biology
(ed. Robert Maue) 121-140 (Elsevier Science, Amsterdam, 2004)).
Regulation of Store-Operated Calcium Entry by Intracellular Calcium
Stores
[0137] Store-operated calcium entry is regulated by the level of
calcium within an intracellular calcium store. Intracellular
calcium stores can be characterized by sensitivity to agents, which
can be physiological or pharmacological, which activate release of
calcium from the stores or inhibit uptake of calcium into the
stores. Different cells have been studied in characterization of
intracellular calcium stores, and stores have been characterized as
sensitive to various agents, including, but not limited to,
IP.sub.3 and compounds that effect the IP.sub.3 receptor,
thapsigargin, ionomycin and/or cyclic ADP-ribose (cADPR) (see,
e.g., Berridge (1993) Nature 361:315-325; Churchill and Louis
(1999) Am. J. Physiol. 276:C426-C434; Dargie et al. (1990) Cell
Regul. 1:279-290; Gerasimenko et al. (1996) Cell 84:473-480;
Gromoda et al. (1995) FEBS Lett. 360:303-306; Guse et al. (1999)
Nature 398:70-73).
[0138] Accumulation of calcium within endoplasmic reticulum and
sarcoplasmic reticulum (SR; a specialized version of the
endoplasmic reticulum in striated muscle) storage organelles is
achieved through sarcoplasmic-endoplasmic reticulum calcium ATPases
(SERCAs), commonly referred to as calcium pumps. During signaling
(i.e., when endoplasmic reticulum channels are activated to provide
for calcium release from the endoplasmic reticulum into the
cytoplasm), endoplasmic reticulum calcium is replenished by the
SERCA pump with cytoplasmic calcium that has entered the cell from
the extracellular medium (Yu and Hinkle (2000) J. Biol. Chem.
275:23648-23653; Hofer et al. (1998) EMBO J. 17:1986-1995).
[0139] Calcium release channels associated with IP.sub.3 and
ryanodine receptors provide for controlled release of calcium from
endoplasmic and sarcoplasmic reticulum into the cytoplasm resulting
in transient increases in cytoplasmic calcium concentration.
IP.sub.3 receptor-mediated calcium release is triggered by IP.sub.3
formed by the break down of plasma membrane phosphoinositides
through the action of phospholipase C, which is activated by
binding of an agonist to a plasma membrane G protein-coupled
receptor or tyrosine kinase. Ryanodine receptor-mediated calcium
release is triggered by an increase in cytoplasmic calcium and is
referred to as calcium-induced calcium release (CICR). The activity
of ryanodine receptors (which have affinity for ryanodine and
caffeine) may also be regulated by cyclic ADP-ribose.
[0140] Thus, the calcium levels in the stores, and in the
cytoplasm, fluctuate. For example, ER free calcium concentration
can decrease from a range of about 60-400 .mu.M to about 1-50 .mu.M
when HeLa cells are treated with histamine, an agonist of
PLC-linked histamine receptors (Miyawaki et al. (1997) Nature
388:882-887). Store-operated calcium entry is activated as the free
calcium concentration of the intracellular stores is reduced.
Depletion of store calcium, as well as a concomitant increase in
cytosolic calcium concentration, can thus regulate store-operated
calcium entry into cells.
Cytoplasmic Calcium Buffering
[0141] Agonist activation of signaling processes in cells can
involve dramatic increases in the calcium permeability of the
endoplasmic reticulum, for example, through opening of IP.sub.3
receptor channels, and the plasma membrane through store-operated
calcium entry. These increases in calcium permeability are
associated with an increase in cytosolic calcium concentration that
can be separated into two components: a "spike" of calcium release
from the endoplasmic reticulum during activation of the IP.sub.3
receptor and a plateau phase which is a sustained elevation of
calcium levels resulting from entry of calcium into the cytoplasm
from the extracellular medium. Upon stimulation, the resting
intracellular free calcium concentration of about 100 nM can rise
globally to greater than 1 .mu.M and higher in microdomains of the
cell. The cell modulates these calcium signals with endogenous
calcium buffers, including physiological buffering by organelles
such as mitochondria, endoplasmic reticulum and Golgi.
Mitochondrial uptake of calcium through a uniporter in the inner
membrane is driven by the large negative mitochondrial membrane
potential, and the accumulated calcium is released slowly through
sodium-dependent and -independent exchangers, and, under some
circumstances, the permeability transition pore (PTP). Thus,
mitochondria can act as calcium buffers by taking up calcium during
periods of cellular activation and can slowly release it later.
Uptake of calcium into the endoplasmic reticulum is regulated by
the sarcoplasmic and endoplasmic reticulum calcium ATPase (SERCA).
Uptake of calcium into the Golgi is mediated by a P-type calcium
transport ATPase (PMR1/ATP2C1). Additionally, there is evidence
that a significant amount of the calcium released upon IP.sub.3
receptor activation is extruded from the cell through the action of
the plasma membrane calcium ATPase. For example, plasma membrane
calcium ATPases provide the dominant mechanism for calcium
clearance in human T cells and Jurkat cells, although
sodium/calcium exchange also contributes to calcium clearance in
human T cells. Within calcium-storing organelles, calcium ions can
be bound to specialized calcium-buffering proteins, such as, for
example, calsequestrins, calreticulins and calnexins. Additionally,
there are calcium-buffering proteins in the cytosol that modulate
calcium spikes and assist in redistribution of calcium ions. Thus,
proteins and other molecules that participate in any of these and
other mechanisms through which cytosolic calcium levels can be
reduced are proteins that are involved in, participate in and/or
provide for cytoplasmic calcium buffering. Thus, cytoplasmic
calcium buffering helps regulate cytoplasmic Ca.sup.2+ levels
during periods of sustained calcium influx through SOC channels or
bursts of Ca.sup.2+ release. Large increases in cytoplasmic
Ca.sup.2+ levels or store refilling deactivate SOCE.
Downstream Calcium Entry-Mediated Events
[0142] In addition to intracellular changes in calcium stores,
store-operated calcium entry affects a multitude of events that are
consequent to or in addition to the store-operated changes. For
example Ca.sup.2+ influx results in the activation of a large
number of calmodulin-dependent enzymes including the serine
phosphatase calcineurin. Activation of calcineurin by an increase
in intracellular calcium results in acute secretory processes such
as mast cell degranulation. Activated mast cells release preformed
granules containing histamine, heparin, TNF.alpha. and enzymes such
as .beta.-hexosaminidase. Some cellular events, such as B and T
cell proliferation, require sustained calcineurin signaling, which
requires a sustained increase in intracellular calcium. A number of
transcription factors are regulated by calcineurin, including NFAT
(nuclear factor of activated T cells), MEF2 and NF.kappa.B. NFAT
transcription factors play important roles in many cell types,
including immune cells. In immune cells NFAT mediates transcription
of a large number of molecules, including cytokines, chemokines and
cell surface receptors. Transcriptional elements for NFAT have been
found within the promoters of cytokines such as IL-2, IL-3, IL-4,
IL-5, IL-8, IL-13, as well as tumor necrosis factor alpha
(TNF.alpha.), granulocyte colony-stimulating factor (G-CSF), and
gamma-interferon (.gamma.-IFN).
[0143] The activity of NFAT proteins is regulated by their
phosphorylation level, which in turn is regulated by both
calcineurin and NFAT kinases. Activation of calcineurin by an
increase in intracellular calcium levels results in
dephosphorylation of NFAT and entry into the nucleus.
Rephosphorylation of NFAT masks the nuclear localization sequence
of NFAT and prevents its entry into the nucleus. Because of its
strong dependence on calcineurin-mediated dephosphorylation for
localization and activity, NFAT is a sensitive indicator of
intracellular free calcium levels.
Diseases, Disorders or Conditions
[0144] Clinical studies demonstrate that the CRAC channel is
absolutely required for the activation of genes underlying the T
cell response to antigen. Sustained calcium entry is needed for
lymphocyte activation and adaptive immune response. Calcium entry
into lymphocytes occurs primarily through the CRAC channels.
Increased calcium leads to NFAT activation and expression of
cytokines required for immune response. Inhibiting the store
operated calcium entry is an efficient way to prevent T cell
activation.
[0145] Inhibition of CRAC channel activity with the compounds
described herein, such as compounds of Formulas (I), (IA), (II),
(IIA), (III), (IIIA), (IV), (IVA), (V), (VA), (VI), (VIA), (VII),
(VIIA), (VIII), (VIIIA), (IX), (IXA), (X), (XI), (XIA), (XII), or
(XIIA) provide a means for providing immunosuppressive therapy as
demonstrated by the elimination of store-operated calcium entry
noted in patients with severe-combined immunodeficiency (SCID). T
cells, fibroblasts, and in some cases B cells, from patients with T
cell immunodeficiency or SCID having a principal defect in T cell
activation show a strong defect in store-operated calcium entry
(Feske et al. (2001) Nature Immunol. 2:316-324; Paratiseti et al.
(1994) J. Biol. Chem. 269:32327-32335; and Le Deist et al. (1995)
Blood 85:1053-1062). SCID patients lack adaptive immune response,
but without any impairment or toxicity in major organs. The SCID
patient phenotype indicates that inhibition of CRAC channels is an
effective strategy for immunosuppression.

[0147] The activation of neutrophils (PMN) by inflammatory
mediators is partly achieved by increasing cytosolic calcium
concentration. Store-operated calcium influx in particular is
thought to play an important role in PMN activation. It has been
shown that trauma increases PMN store-operated calcium influx
(Hauser et al. (2000) J. Trauma Injury Infection and Critical Care
48 (4):592-598) and that prolonged elevations of cytosolic calcium
concentration due to enhanced store-operated calcium influx may
alter stimulus-response coupling to chemotaxins and contribute to
PMN dysfunction after injury. Modulation of PMN cytosolic calcium
concentration through store-operated calcium channels might
therefore be useful in regulating PMN-mediated inflammation and
spare cardiovascular function after injury, shock or sepsis (Hauser
et al. (2001) J. Leukocyte Biology 69 (1):63-68).
[0148] Calcium plays a critical role in lymphocyte activation.
Activation of lymphocytes, e.g., by antigen stimulation, results in
rapid increases in intracellular free calcium concentration and
activation of transcription factors, including nuclear factor of
activated T cells (NFAT), NF-.kappa.B, JNK1, MEF2 and CREB. NFAT is
a key transcriptional regulator of the IL-2 (and other cytokine)
genes (see, e.g. Lewis (2001) Annu. Rev. Immunol 19:497-521). A
sustained elevation of intracellular calcium level is required to
keep NFAT in a transcriptionally active state, and is dependent on
store-operated calcium entry. Reduction or blocking of
store-operated calcium entry in lymphocytes blocks
calcium-dependent lymphocyte activation. Thus, modulation of
intracellular calcium, and particularly store-operated calcium
entry (e.g., reduction in, elimination of store-operated calcium
entry), in lymphocytes can be a method for treating immune and
immune-related disorders, including, for example, chronic immune
diseases/disorders, acute immune diseases/disorders, autoimmune and
immunodeficiency diseases/disorders, diseases/disorders involving
inflammation, organ transplant graft rejections and
graft-versus-host disease and altered (e.g., hyperactive) immune
responses. For example treatment of an autoimmune disease/disorder
might involve reducing, blocking or eliminating store-operated
calcium entry in lymphocytes.
[0149] Examples of immune disorders include psoriasis, rheumatoid
arthritis, vasculitis, inflammatory bowel disease, dermatitis,
osteoarthritis, asthma, inflammatory muscle disease, allergic
rhinitis, vaginitis, interstitial cystitis, scleroderma,
osteoporosis, eczema, allogeneic or xenogeneic transplantation
(organ, bone marrow, stem cells and other cells and tissues) graft
rejection, graft-versus-host disease, lupus erythematosus,
inflammatory disease, type I diabetes, pulmonary fibrosis,
dermatomyositis, Sjogren's syndrome, thyroiditis (e.g., Hashimoto's
and autoimmune thyroiditis), myasthenia gravis, autoimmune
hemolytic anemia, multiple sclerosis, cystic fibrosis, chronic
relapsing hepatitis, primary biliary cirrhosis, allergic
conjunctivitis and atopic dermatitis.

connection with treatment of malignancies, including, but not
limited to, malignancies of lymphoreticular origin, bladder cancer,
breast cancer, colon cancer, endometrial cancer, head and neck
cancer, lung cancer, melanoma, ovarian cancer, prostate cancer and
rectal cancer. Store-operated calcium entry may play an important
role in cell proliferation in cancer cells (Weiss et al. (2001)
International Journal of Cancer 92 (6):877-882).
[0151] Inhibition of SOCE is sufficient to prevent tumor cell
proliferation. The pyrazole derivative BTP-2, a direct I.sub.CRAC
blocker inhibits SOCE and proliferation in Jurkat cells (Zitt et
al., J. Biol. Chem., 279, 12427-12437, 2004) and in colon cancer
cells. It has been suggested that sustained SOCE requires
mitochonrial Ca.sup.2+ uptake (Nunez et al., J. Physiol. 571.1,
57-73, 2006) and that prevention of mitochondrial Ca.sup.2+ uptake
leads to SOCE inhibition (Hoth et al., P.N.A.S., 97, 10607-10612,
2000; Hoth et al., J. Cell. Biol. 137, 633-648, 1997; Glitsch et
al., EMBO J., 21, 6744-6754, 2002). Stimulation of Jurkat cells
induces sustained SOCE and activation of the Ca.sup.2+-dependent
phosphatase calcineurin that dephosphorylates NFAT, promoting
expression of interleukin-2 and proliferation. Compounds of Formula

treatment of cancer or other proliferative diseases or
conditions.
Liver Diseases and Disorders

compositions thereof, and methods provided herein include hepatic
or liver diseases and disorders. These diseases and disorders
include but are not limited to liver injury, for example, due to
transplantation, hepatitis and cirrhosis.
[0153] Store-operated calcium entry has been implicated in chronic
liver disease (Tao et al. (1999) J. Biol. Chem.,
274(34):23761-23769) as well as transplantation injury after cold
preservation-warm reoxygenation (Elimadi et al. (2001) Am J.
Physiology, 281(3 Part 1):G809-G815).
Kidney Diseases and Disorders
[0154] Diseases or disorders that can be treated or prevented using
the methods provided herein include kidney or renal diseases and
disorders. Mesangial cell hyperplasia is often a key feature of
such diseases and disorders. Such diseases and disorders may be
caused by immunological or other mechanisms of injury, including
IgAN, membranoproliferative glomerulonephritis or lupus nephritis.
Imbalances in the control of mesangial cell replication also appear
to play a key role in the pathogenesis of progressive renal
failure.
[0155] The turnover of mesangial cells in normal adult kidney is
very low with a renewal rate of less than 1%. A prominent feature
of glomerular/kidney diseases is mesangial hyperplasia due to
elevated proliferation rate or reduced cell loss of mesangial
cells. When mesangial cell proliferation is induced without cell
loss, for example due to mitogenic stimulation,
mesangioproliferative glomerulonephritis can result. Data have
indicated that regulators of mesangial cell growth, particularly
growth factors, may act by regulating store-operated calcium
channels (Ma et al. (2001) J Am. Soc. Of Nephrology, 12:(1) 47-53).
Modulators of store-operated calcium influx may aid in the
treatment of glomerular diseases by inhibiting mesangial cell
proliferation.
Store Operated Calcium Channels
[0156] Clinical studies demonstrate that the CRAC channel, a type
of SOC channel, is absolutely required for the activation of genes
underlying the T cell response to antigen (Partiseti et al., J
Biol. Chem., 269, 32327-32335, 1994; Feske et al., Curr. Biol. 15,
1235-1241, 2005). SOCE can contribute directly to the elevation of
cytosolic Ca.sup.2+ levels ([Ca.sup.2+].sub.i), as in T lymphocytes
where CRAC channels generate the sustained Ca.sup.2+ signals needed
to drive gene expression underlying T cell activation by antigen.
Sustained calcium entry is needed for lymphocyte activation and
adaptive immune response. Calcium entry into lymphocytes occurs
primarily through the CRAC channels.
[0157] Increased calcium levels lead to NFAT activation and
expression of cytokines required for immune response.
[0158] The CRAC channel has a distinctive biophysical fingerprint,
quantifiable store-dependence, and essential function in T cells.
Studies have shown that CRAC channels are formed from two component
proteins, which interact to form CRAC channels. The CRAC channel is
assembled by two functional components, STIM1 and Orai1. STIM1
(stromal interaction molecule 1) was identified as the mammalian ER
Ca.sup.2+ sensor (Liou, J. et al. Curr. Biol. 15, 1235-1241 (2005);
Roos, J. et al. J. Cell Biol. 169, 435-445 (2005); WO 20041078995;
US 2007/0031814). Orai1/CRACM1 was identified as a component of the
mammalian CRAC channel (Feske, S. et al. Nature 441, 179-185
(2006); Vig, M. et al. Science 312, 1220-1223 (2006); Zhang, S. L.
et al. Proc. Natl Acad. Sci. USA 103, 9357-9362 (2006)).
[0159] STIM1 is the sensor of Ca.sup.2+ within ER Ca.sup.2+ stores,
moving in response to store depletion into ER puncta close to the
plasma membrane. Orai1 is a pore forming CRAC channel subunit in
the plasma membrane. The two membrane proteins STIM1 and Orai1 have
each been shown to be essential for the activation of CRAC
channels.
[0160] Expression of both STIM1 and Orai1 in human embryonic kidney
293 cells (HEK293 cells) reconstitute functional CRAC channels.
Expression of Orai1 alone strongly reduces store-operated Ca.sup.2+
entry in HEK293 cells and the Ca.sup.2+ release-activated Ca.sup.2+
current (I.sub.CRAC) in rat basophilic leukemia cells. However,
expressed along with the store-sensing STIM1 protein, Orai1 causes
a massive increase in SOCE, enhancing the rate of Ca.sup.2+ entry
by up to 103-fold. This Ca.sup.2+ entry is entirely store dependent
since the same co-expression causes no measurable store-independent
Ca.sup.2+ entry. The entry is completely blocked by the store
operated channel blocker, 2-aminoethoxydiphenylborate. STIM
proteins are mediate Ca.sup.2+ store-sensing and endoplasmic
reticulum-plasma membrane coupling with no intrinsic channel
properties. Orai1 contributes the plasma membrane channel component
responsible for Ca.sup.2+ entry. The suppression of CRAC channel
function by Orai1 overexpression reflects a required stoichiometry
between STIM1 and Orai1 (Soboloff et al., J. Biol. Chem. Vol. 281,
no. 30, 20661-20665, 2006).
Stromal Interacting Molecule (STIM) Proteins
[0161] In an RNAi screen in Drosophila S2 cells using
thapsigargin-activated Ca.sup.2+ entry as a marker for
store-operated channels one gene gave a substantially reduced
Ca.sup.2+ entry, and that gene coded for the protein stromal
interaction molecule (Stim) (Roos, J. et al. J. Cell Biol. 169,
435-445, 2005). There are two homologues of Stim in mammalian
cells, STIM1 and STIM2, both of which appear to be distributed
ubiquitously (Williams et al., Biochem J. 2001 Aug. 1; 357(Pt
3):673-85). STIM1 is the ER Ca.sup.2+ sensor for store-operated
Ca.sup.2+ entry. STIM1 is a 77 kDa type I membrane protein with
multiple predicted protein interaction or signaling domains and is
located predominantly in the ER, but also to a limited extent in
the plasma membrane.
[0162] Knockdown of STIM1 by RNAi substantially reduced I.sub.CRAC
in Jurkat T cells, and store-operated Ca.sup.2+ entry in HEK293
epithelial cells and SH-SY5Y neuroblastoma cells. However,
knockdown of the closely related STIM2 had no effect. These results
indicate an essential role of STIM (Drosophila) and STIM1 (mammals)
in the mechanism of activation of store-operated channels. It is
unlikely that STIM1 is the store-operated channel itself. It has no
channel-like sequence, and overexpression of the protein only
modestly enhances Ca.sup.2+ entry. STIM1 is located both on the
plasma membrane and intracellular membranes like the ER (Manji et
al., Biochim Biophys Acta. 2000 Aug. 31; 1481(1):147-55. 2000). The
protein sequence suggests that it spans the membrane once, with its
NH.sub.2 terminus oriented toward the lumen of the ER or the
extracellular space. The NH.sub.2 terminus contains an EF-hand
domain, and functions as the Ca.sup.2+ sensor in the ER. The
protein also contains protein-protein interaction domains, notably
coiled-coiled domains in the cytoplasm and a sterile motif (SAM) in
the ER (or extracellular space), both near the predicted
transmembrane domain. STIM1 can oligomerize and thus the protein in
the ER and plasma membrane could interact bridging the two (Roos,
J. et al. J. Cell Biol. 169, 435-445 (2005)).
[0163] Total internal reflection fluorescence (TIRF) and confocal
microscopy reveal that STIM1 is distributed throughout the ER when
Ca.sup.2+ stores are full, but redistributes into discrete puncta
near the plasma membrane on store depletion. Although the
redistribution of STIM1 into junctional ER regions is slow (Liou,
J. et al. Curr. Biol. 15, 1235-1241 (2005); Zhang, S. L. et al.
Nature 437, 902-905 (2005), it does precede the opening of CRAC
channels by several seconds (Wu et al., J. Cell Biol. 174, 803-813
(2006)) and is therefore rapid enough to be an essential step in
the activation of CRAC channels.
[0164] It has been suggested that store depletion causes the
insertion of STIM1 into the plasma membrane where it may control
store operated calcium entry through the CRAC channels (Zhang, S.
L. et al. Nature 437, 902-905 (2005); Spassova, M. A. et al. Proc.
Natl Acad. Sci. USA 103, 4040-4045 (2006)).
[0165] The critical evidence for STIM1 as the Ca.sup.2+ sensor for
SOCE is that mutation of predicted Ca.sup.2-binding residues of the
EF hand structural motif, expected to reduce its affinity for
Ca.sup.2+ and hence mimic the store-depleted state, causes STIM1 to
redistribute spontaneously into puncta and trigger constitutive
Ca.sup.2+ influx through SOCs even when stores are full (Spassova,
M. A. et al. Proc. Natl Acad. Sci. USA 103, 4040-4045 (2006); Liou,
J. et al. Curr. Biol. 15, 1235-1241 (2005)).
Orai Proteins
[0166] Orai1 (also known as CRACM1) is a widely expressed, 33 kDa
plasma membrane protein with 4 transmembrane domains and a lack of
significant sequence homology to other ion channels (Vig, M. et al.
Science 312, 1220-1223 (2006); Zhang, S. L. et al. Proc. Natl Acad.
Sci. USA 103, 9357-9362 (2006)).
[0167] Studies of T cells from human patients with a severe
combined immunodeficiency (SCID) syndrome, in which T cell receptor
engagement or store depletion failed to activate Ca.sup.2+ entry,
was shown to be due to a single point mutation in Orai1 (Feske, S.
et al. Nature 441, 179-185 (2006)).
[0168] Other mammalian Orai homologues exist, e.g. Orai2 and Orai3,
however their function is not clearly defined. Orai2 and Orai3 can
exhibit SOC channel activity when overexpressed with STIM1 in HEK
cells (Mercer, J. C. et al. J. Biol. Chem. 281, 24979-24990
(2006)).
[0169] Evidence that Orai1 contributes to the CRAC channel pore was
obtained by Orai1 mutagenesis studies. Selectivity of the CRAC
channel for Ca.sup.2+ ions was shown by mutations at either Glu 106
or Glu 190, which weaken the ability of Ca.sup.2+ binding in order
block permeation of monovalent cations (similar to mechanisms
described for voltage-gated Ca.sup.2+ channels) (Yeromin, A. V. et
al. Nature 443, 226-229 (2006); Vig, M. et al. Curr. Biol. 16,
2073-2079 (2006); Prakriya, M. et al. Nature 443, 230-233
(2006)).
[0170] Neutralizing the charge on a pair of aspartates in the I-II
loop (Asp 110 and Asp 112) reduces block by Gd.sup.3+ and block of
outward current by extracellular Ca.sup.2+, indicating that these
negatively charged sites may promote accumulation of polyvalent
cations near the mouth of the pore.
[0171] Currents observed through overexpression of Orai1 closely
resemble I.sub.CRAC, and the fact that Orai1 can form multimers
(Yeromin, A. V. et al. Nature 443, 226-229 (2006); Vig, M. et al.
Curr. Biol. 16, 2073-2079 (2006); Prakriya, M. et al. Nature 443,
230-233 (2006)), makes it likely that the native CRAC channel is
either a multimer of Orai1 alone or in combination with the closely
related subunits Orai2 and/or Orai3.
Functional Store Operated Calcium Channels
[0172] The characterization of SOC channels has been largely
obtained by one type of SOC channel, the CRAC channel. CRAC channel
activity is triggered by the loss of Ca.sup.2+ from the ER lumen,
which is coupled to the opening of CRAC channels in the plasma
membrane through the actions of STIM1 and Orai1. Depletion of
Ca.sup.2+ is sensed by STIM1, causing it to accumulate in
junctional ER adjacent to the plasma membrane. In a TIRF-based
Ca.sup.2+-imaging study to map the locations of open CRAC channels,
[Ca.sup.2+].sub.i elevations were seen to co-localize with STIM1
puncta, showing directly that CRAC channels open only in extreme
proximity to these sites (Luik, et al., J. Cell Biol. 174, 815-825
(2006)).
[0173] In cells co-expressing both STIM1 and Orai1, store depletion
causes Orai1 itself to move from a dispersed distribution to
accumulate in the plasma membrane directly opposite STIM1, enabling
STIM1 to activate the channel (Luik, et al., J. Cell Biol. 174,
815-825 (2006); Xu, P. et al. Biochem. Biophys. Res. Commun. 350,
969-976 (2006)). Thus, CRAC channels are formed by apposed clusters
of STIM1 in the ER and Orai1 in the plasma membrane. The junctional
gap between the ER and plasma membrane where Orai1/STIM 1 clusters
from (about 10-25 nm) may be small enough to permit protein-protein
interactions between STIM 1 and Orai1. This is supported by the
fact that overexpressed STIM1 and Orai1 can be
co-immunoprecipitated (Yeromin, A. V. et al. Nature 443, 226-229
(2006); Vig, M. et al. Curr. Biol. 16, 2073-2079 (2006)).
[0174] Thus, STIM1 and Orai1 interact either directly or as members
of a multiprotein complex. Support for this was observed when the
expression of the cytosolic portion of STIM1 by itself was
sufficient to activate CRAC channels in one study (Huang, G. N. et
al. Nature Cell Biol. 8, 1003-1010 (2006)), and the effects of
deleting the ERM/coiled-coil and other C-terminal domains suggest
roles in STIM1 clustering and SOC channel activation (Baba, Y. et
al. Proc. Natl Acad. Sci. USA 103, 16704-16709 (2006)). On the
luminal side of STIM1, the isolated EF-SAM region forms dimers and
higher-order multimers on removal of Ca.sup.2+ in vitro, indicating
that STIM1 oligomerization may be an early step in store operated
calcium activation (Stathopulos, et al., J. Biol. Chem. 281,
35855-35862 (2006)).
[0175] In some embodiments, compounds of Formula (I), (IA), (II),

Monitoring or Assessing Effects on Intracellular Calcium
[0177] In some embodiments, monitoring or assessing the effect of a
compound of Formula (I), (IA), (II), (IIA), (III), (IIIA), (IV),
(IVA), (V), (VA), (VI), (VIA), (VII), (VIIA), (VIII), (VIIIA),
(IX), (IXA), (X), (XI), (XIA), (XII), or (XIIA) on intracellular
calcium in any of the screening/identification methods described
herein, a direct or indirect evaluation or measurement of cellular
(including cytosolic and intracellular organelle or compartment)
calcium and/or movement of ions into, within or out of a cell,
organelle, calcium store or portions thereof (e.g., a membrane) are
conducted. A variety of methods are described herein for evaluating
calcium levels and ion movements or flux. The particular method
used and the conditions employed depend on whether a particular
aspect of intracellular calcium is being monitored or assessed. For
example, in some embodiments described herein, reagents and
conditions are known, and are used, for specifically evaluating
store-operated calcium entry, resting cytosolic calcium levels,
calcium buffering and calcium levels and uptake by or release from
intracellular organelles and calcium stores. In other embodiments,
the effect of a compound of Formula (I), (IA), (II), (IIA), (III),
(IIIA), (IV), (IVA), (V), (VA), (VI), (VIA), (VII), (VIIA), (VIII),
(VIIIA), (IX), (IXA), (X), (XI), (XIA), (XII), or (XIIA) on
intracellular calcium is monitored or assessed using, for example,
a cell, an intracellular organelle or calcium storage compartment,
a membrane (including, e.g., a detached membrane patch or a lipid
bilayer) or a cell-free assay system (e.g., outside-out membrane
vesicle). Generally, some aspect of intracellular calcium is
monitored or assessed in the presence of test agent and compared to
a control, e.g., intracellular calcium in the absence of test
agent.
Methods of Modulating Intracellular Calcium
[0178] In some embodiments, modulation of intracellular calcium is
any alteration or adjustment in intracellular calcium including but
not limited to alteration of calcium concentration or level in the
cytoplasm and/or intracellular calcium storage organelles, e.g.,
endoplasmic reticulum, alteration in the movement of calcium into,
out of and within a cell or intracellular calcium store or
organelle, alteration in the location of calcium within a cell, and
alteration of the kinetics, or other properties, of calcium fluxes
into, out of and within cells. In some embodiments, intracellular
calcium modulation involves alteration or adjustment, e.g.
reduction or inhibition, of store-operated calcium entry, cytosolic
calcium buffering, calcium levels in or movement of calcium into,
out of or within an intracellular calcium store or organelle,
and/or basal or resting cytosolic calcium levels. In some
embodiments, modulation of intracellular calcium involves an
alteration or adjustment in receptor-mediated ion (e.g., calcium)
movement, second messenger-operated ion (e.g., calcium) movement,
calcium influx into or efflux out of a cell, and/or ion (e.g.,
calcium) uptake into or release from intracellular compartments,
including, for example, endosomes and lysosomes.
[0179] In one aspect, compounds described herein modulate
intracellular calcium, such as but not limited to, modulation (e.g.
reduction or inhibition) of SOC channel activity, such as
inhibition of CRAC channel activity (e.g. inhibition of I.sub.CRAC,
inhibition of SOCE), in an immune system cell (e.g., a lymphocyte,
white blood cell, T cell, B cell), a fibroblast (or a cell derived
from a fibroblast), or an epidermal, dermal or skin cell (e.g., a
keratinocyte). In some embodiments, the step of modulating one or
more proteins involved in modulating intracellular calcium (e.g. a
STIM protein and/or Orai protein) involves, for example, reducing
the level, expression of, an activity of, function of and/or
molecular interactions of a protein. For instance, if a cell
exhibits an increase in calcium levels or lack of regulation of an
aspect of intracellular calcium modulation, e.g., store-operated
calcium entry, then in other embodiments, modulating involves
reducing the level of, expression of, an activity or function of,
or a molecular interaction of a protein, e.g. a STIM protein and/or
Orai protein.

Further Forms of Compounds
[0718] The compounds described herein may in some cases exist as
diastereomers, enantiomers, or other stereoisomeric forms. The
compounds presented herein include all diastereomeric,
enantiomeric, and epimeric forms as well as the appropriate
mixtures thereof. Separation of stereoisomers may be performed by
chromatography or by the forming diastereomeric and separation by
recrystallization, or chromatography, or any combination thereof.
(Jean Jacques, Andre Collet, Samuel H. Wilen, "Enantiomers,
Racemates and Resolutions", John Wiley And Sons, Inc., 1981, herein
incorporated by reference for this disclosure). Stereoisomers may
also be obtained by stereoselective synthesis.
[0719] In some situations, compounds may exist as tautomers. All
tautomers are included within the formulas described herein.
[0720] The methods and compositions described herein include the
use of amorphous forms as well as crystalline forms (also known as
polymorphs). The compounds described herein may be in the form of
pharmaceutically acceptable salts. As well, active metabolites of
these compounds having the same type of activity are included in
the scope of the present disclosure. In addition, the compounds
described herein can exist in unsolvated as well as solvated forms
with pharmaceutically acceptable solvents such as water, ethanol,
and the like. The solvated forms of the compounds presented herein
are also considered to be disclosed herein.
[0721] In some embodiments, compounds described herein may be
prepared as prodrugs. A "prodrug" refers to an agent that is
converted into the parent drug in vivo. Prodrugs are often useful
because, in some situations, they may be easier to administer than
the parent drug. They may, for instance, be bioavailable by oral
administration whereas the parent is not. The prodrug may also have
improved solubility in pharmaceutical compositions over the parent
drug. An example, without limitation, of a prodrug would be a
compound described herein, which is administered as an ester (the
"prodrug") to facilitate transmittal across a cell membrane where
water solubility is detrimental to mobility but which then is
metabolically hydrolyzed to the carboxylic acid, the active entity,
once inside the cell where water-solubility is beneficial. A
further example of a prodrug might be a short peptide
(polyaminoacid) bonded to an acid group where the peptide is
metabolized to reveal the active moiety. In certain embodiments,
upon in vivo administration, a prodrug is chemically converted to
the biologically, pharmaceutically or therapeutically active form
of the compound. In certain embodiments, a prodrug is enzymatically
metabolized by one or more steps or processes to the biologically,
pharmaceutically or therapeutically active form of the
compound.
[0722] To produce a prodrug, a pharmaceutically active compound is
modified such that the active compound will be regenerated upon in
vivo administration. The prodrug can be designed to alter the
metabolic stability or the transport characteristics of a drug, to
mask side effects or toxicity, to improve the flavor of a drug or
to alter other characteristics or properties of a drug. In some
embodiments, by virtue of knowledge of pharmacodynamic processes
and drug metabolism in vivo, once a pharmaceutically active
compound is determined, prodrugs of the compound are designed.

[0723] Prodrug forms of the herein described compounds, wherein the
prodrug is metabolized in vivo to produce a compound having the
structure of Formula (I), (IA), (II), (IIA), (III), (IIIA), (IV),
(IVA), (V), (VA), (VI), (VIA), (VII), (VIIA), (VIII), (VIIIA),
(IX), (IXA), (X), (XI), (XIA), (XII), or (XIIA) as set forth herein
are included within the scope of the claims. In some cases, some of
the herein-described compounds may be a prodrug for another
derivative or active compound.
[0724] Prodrugs are often useful because, in some situations, they
may be easier to administer than the parent drug. They may, for
instance, be bioavailable by oral administration whereas the parent
is not. The prodrug may also have improved solubility in
pharmaceutical compositions over the parent drug. Prodrugs may be
designed as reversible drug derivatives, for use as modifiers to
enhance drug transport to site-specific tissues. In some
embodiments, the design of a prodrug increases the effective water
solubility. See, e.g., Fedorak et al., Am. J. Physiol.,

[0725] Sites on the aromatic ring portion of compounds described
herein can be susceptible to various metabolic reactions, therefore
incorporation of appropriate substituents on the aromatic ring
structures, such as, by way of example only, halogens can reduce,
minimize or eliminate this metabolic pathway.
[0726] The compounds described herein may be labeled isotopically
(e.g. with a radioisotope) or by other means, including, but not
limited to, the use of chromophores or fluorescent moieties,
bioluminescent labels, photoactivatable or chemiluminescent
labels.
[0727] Compounds described herein include isotopically-labeled
compounds, which are identical to those recited in the various
formulae and structures presented herein, but for the fact that one
or more atoms are replaced by an atom having an atomic mass or mass
number different from the atomic mass or mass number usually found
in nature. Examples of isotopes that can be incorporated into the
present compounds include isotopes of hydrogen, carbon, nitrogen,
oxygen, fluorine and chlorine, such as, for example, .sup.2H,
.sup.3H, .sup.13C, .sup.14C, .sup.15N, .sup.18O, .sup.17O, .sup.3S,
.sup.18F, .sup.36Cl, respectively. Certain isotopically-labeled
compounds described herein, for example those into which
radioactive isotopes such as .sup.3H and .sup.14C are incorporated,
are useful in drug and/or substrate tissue distribution assays.
Further, substitution with isotopes such as deuterium, i.e.,
.sup.2H, can afford certain therapeutic advantages resulting from
greater metabolic stability, such as, for example, increased in
vivo half-life or reduced dosage requirements.
[0728] In additional or further embodiments, the compounds
described herein are metabolized upon administration to an organism
in need to produce a metabolite that is then used to produce a
desired effect, including a desired therapeutic effect.
[0729] Compounds described herein may be formed as, and/or used as,
pharmaceutically acceptable salts. The type of pharmaceutical
acceptable salts, include, but are not limited to: (1) acid
addition salts, formed by reacting the free base form of the
compound with a pharmaceutically acceptable: inorganic acid, such
as, for example, hydrochloric acid, hydrobromic acid, sulfuric
acid, phosphoric acid, metaphosphoric acid, and the like; or with
an organic acid, such as, for example, acetic acid, propionic acid,
hexanoic acid, cyclopentanepropionic acid, glycolic acid, pyruvic
acid, lactic acid, malonic acid, succinic acid, malic acid, maleic
acid, fumaric acid, trifluoroacetic acid, tartaric acid, citric
acid, benzoic acid, 3-(4-hydroxybenzoyl)benzoic acid, cinnamic
acid, mandelic acid, methanesulfonic acid, ethanesulfonic acid,
1,2-ethanedisulfonic acid, 2-hydroxyethanesulfonic acid,
benzenesulfonic acid, toluenesulfonic acid, 2-naphthalenesulfonic
acid, 4-methylbicyclo-[2.2.2]oct-2-ene-1-carboxylic acid,
glucoheptonic acid, 4,4'-methylenebis-(3-hydroxy-2-ene-1-carboxylic
acid), 3-phenylpropionic acid, trimethylacetic acid, tertiary
butylacetic acid, lauryl sulfuric acid, gluconic acid, glutamic
acid, hydroxynaphthoic acid, salicylic acid, stearic acid, muconic
acid, butyric acid, phenylacetic acid, phenylbutyric acid, valproic
acid, and the like; (2) salts formed when an acidic proton present
in the parent compound is replaced by a metal ion, e.g., an alkali
metal ion (e.g. lithium, sodium, potassium), an alkaline earth ion
(e.g. magnesium, or calcium), or an aluminum ion. In some cases,
compounds described herein may coordinate with an organic base,
such as, but not limited to, ethanolamine, diethanolamine,
triethanolamine, tromethamine, N-methylglucamine,
dicyclohexylamine, tris(hydroxymethyl)methylamine. In other cases,
compounds described herein may form salts with amino acids such as,
but not limited to, arginine, lysine, and the like. Acceptable
inorganic bases used to form salts with compounds that include an
acidic proton, include, but are not limited to, aluminum hydroxide,
calcium hydroxide, potassium hydroxide, sodium carbonate, sodium
hydroxide, and the like.
[0730] It should be understood that a reference to a
pharmaceutically acceptable salt includes the solvent addition
forms or crystal forms thereof, particularly solvates or
polymorphs. Solvates contain either stoichiometric or
non-stoichiometric amounts of a solvent, and may be formed during
the process of crystallization with pharmaceutically acceptable
solvents such as water, ethanol, and the like. Hydrates are formed
when the solvent is water, or alcoholates are formed when the
solvent is alcohol. Solvates of compounds described herein can be
conveniently prepared or formed during the processes described
herein. In addition, the compounds provided herein can exist in
unsolvated as well as solvated forms. In general, the solvated
forms are considered equivalent to the unsolvated forms for the
purposes of the compounds and methods provided herein.
[0731] In some embodiments, compounds described herein, such as
compounds of Formula (I), (IA), (II), (IIA), (III), (IIIA), (IV),
(IVA), (V), (VA), (VI), (VIA), (VII), (VIIA), (VIII), (VIIIA),
(IX), (IXA), (X), (XI), (XIA), (XII), or (XIIA), are in various
forms, including but not limited to, amorphous forms, milled forms
and nano-particulate forms. In addition, compounds described herein
include crystalline forms, also known as polymorphs. Polymorphs
include the different crystal packing arrangements of the same
elemental composition of a compound. Polymorphs usually have
different X-ray diffraction patterns, melting points, density,
hardness, crystal shape, optical properties, stability, and
solubility. Various factors such as the recrystallization solvent,
rate of crystallization, and storage temperature may cause a single
crystal form to dominate.
[0732] The screening and characterization of the pharmaceutically
acceptable salts, polymorphs and/or solvates may be accomplished
using a variety of techniques including, but not limited to,
thermal analysis, x-ray diffraction, spectroscopy, vapor sorption,
and microscopy. Thermal analysis methods address thermo chemical
degradation or thermo physical processes including, but not limited
to, polymorphic transitions, and such methods are used to analyze
the relationships between polymorphic forms, determine weight loss,
to find the glass transition temperature, or for excipient
compatibility studies. Such methods include, but are not limited
to, Differential scanning calorimetry (DSC), Modulated Differential
Scanning Calorimetry (MDCS), Thermogravimetric analysis (TGA), and
Thermogravi-metric and Infrared analysis (TG/IR). X-ray diffraction
methods include, but are not limited to, single crystal and powder
diffractometers and synchrotron sources. The various spectroscopic
techniques used include, but are not limited to, Raman, FTIR,
UV-VIS, and NMR (liquid and solid state). The various microscopy
techniques include, but are not limited to, polarized light
microscopy, Scanning Electron Microscopy (SEM) with Energy
Dispersive X-Ray Analysis (EDX), Environmental Scanning Electron
Microscopy with EDX (in gas or water vapor atmosphere), IR
microscopy, and Raman microscopy.

Use of Protecting Groups
[0738] In the reactions described, it may be necessary to protect
reactive functional groups, for example hydroxy, amino, imino, thio
or carboxy groups, where these are desired in the final product, in
order to avoid their unwanted participation in reactions.
Protecting groups are used to block some or all of the reactive
moieties and prevent such groups from participating in chemical
reactions until the protective group is removed. It is preferred
that each protective group be removable by a different means.
Protective groups that are cleaved under totally disparate reaction
conditions fulfill the requirement of differential removal.
[0739] Protective groups can be removed by acid, base, reducing
conditions (such as, for example, hydrogenolysis), and/or oxidative
conditions. Groups such as trityl, dimethoxytrityl, acetal and
t-butyldimethylsilyl are acid labile and may be used to protect
carboxy and hydroxy reactive moieties in the presence of amino
groups protected with Cbz groups, which are removable by
hydrogenolysis, and Fmoc groups, which are base labile. Carboxylic
acid and hydroxy reactive moieties may be blocked with base labile
groups such as, but not limited to, methyl, ethyl, and acetyl in
the presence of amines blocked with acid labile groups such as
t-butyl carbamate or with carbamates that are both acid and base
stable but hydrolytically removable.
[0740] Carboxylic acid and hydroxy reactive moieties may also be
blocked with hydrolytically removable protective groups such as the
benzyl group, while amine groups capable of hydrogen bonding with
acids may be blocked with base labile groups such as Fmoc.
Carboxylic acid reactive moieties may be protected by conversion to
simple ester compounds as exemplified herein, which include
conversion to alkyl esters, or they may be blocked with
oxidatively-removable protective groups such as
2,4-dimethoxybenzyl, while co-existing amino groups may be blocked
with fluoride labile silyl carbamates.
[0741] Allyl blocking groups are useful in then presence of acid-
and base-protecting groups since the former are stable and can be
subsequently removed by metal or pi-acid catalysts. For example, an
allyl-blocked carboxylic acid can be deprotected with a
Pd.sup.0-catalyzed reaction in the presence of acid labile t-butyl
carbamate or base-labile acetate amine protecting groups. Yet
another form of protecting group is a resin to which a compound or
intermediate may be attached. As long as the residue is attached to
the resin, that functional group is blocked and cannot react. Once
released from the resin, the functional group is available to
react.
[0742] Typically blocking/protecting groups may be selected
from:
##STR00134##
[0743] Other protecting groups, plus a detailed description of
techniques applicable to the creation of protecting groups and
their removal are described in Greene and Wuts, Protective Groups
in Organic Synthesis, 3rd Ed., John Wiley & Sons, New York,
N.Y., 1999, and Kocienski, Protective Groups, Thieme Verlag, New
York, N.Y., 1994, which are incorporated herein by reference for

[0798] "Bioavailability" refers to the percentage of the weight of
the compound disclosed herein (e.g. compound of Formula (I), (IA),
(II), (IIA), (III), (IIIA), (IV), (IVA), (V), (VA), (VI), (VIA),
(VII), (VIIA), (VIII), (VIIIA), (IX), (IXA), (X), (XI), (XIA),

(IX), (IXA), (X), (XI), (XIA), (XII), or (XIIA) disclosed herein,
in the plasma component of blood of a subject. It is understood
that the plasma concentration of compounds described herein may
vary significantly between subjects, due to variability with
respect to metabolism and/or possible interactions with other
therapeutic agents. In accordance with one embodiment disclosed
herein, the blood plasma concentration of the compounds disclosed
herein may vary from subject to subject. Likewise, values such as
maximum plasma concentration (Cmax) or time to reach maximum plasma
concentration (Tmax), or total area under the plasma concentration
time curve (AUC(0-.infin.)) may vary from subject to subject. Due
to this variability, the amount necessary to constitute "a
therapeutically effective amount" of a compound may vary from
subject to subject.
[0800] As used herein, "calcium homeostasis" refers to the
maintenance of an overall balance in intracellular calcium levels
and movements, including calcium signaling, within a cell.
[0801] As used herein, "intracellular calcium" refers to calcium
located in a cell without specification of a particular cellular
location. In contrast, "cytosolic" or "cytoplasmic" with reference
to calcium refers to calcium located in the cell cytoplasm.
[0802] As used herein, an effect on intracellular calcium is any
alteration of any aspect of intracellular calcium, including but
not limited to, an alteration in intracellular calcium levels and
location and movement of calcium into, out of or within a cell or
intracellular calcium store or organelle. For example, an effect on
intracellular calcium can be an alteration of the properties, such
as, for example, the kinetics, sensitivities, rate, amplitude, and
electrophysiological characteristics, of calcium flux or movement
that occurs in a cell or portion thereof. An effect on
intracellular calcium can be an alteration in any intracellular
calcium-modulating process, including, store-operated calcium
entry, cytosolic calcium buffering, and calcium levels in or
movement of calcium into, out of or within an intracellular calcium
store. Any of these aspects can be assessed in a variety of ways
including, but not limited to, evaluation of calcium or other ion
(particularly cation) levels, movement of calcium or other ion
(particularly cation), fluctuations in calcium or other ion
(particularly cation) levels, kinetics of calcium or other ion
(particularly cation) fluxes and/or transport of calcium or other
ion (particularly cation) through a membrane. An alteration can be
any such change that is statistically significant. Thus, for
example if intracellular calcium in a test cell and a control cell
is said to differ, such difference can be a statistically
significant difference.
[0803] As used herein, "involved in" with respect to the
relationship between a protein and an aspect of intracellular
calcium or intracellular calcium regulation means that when
expression or activity of the protein in a cell is reduced, altered
or eliminated, there is a concomitant or associated reduction,
alteration or elimination of one or more aspects of intracellular
calcium or intracellular calcium regulation. Such an alteration or
reduction in expression or activity can occur by virtue of an
alteration of expression of a gene encoding the protein or by
altering the levels of the protein. A protein involved in an aspect
of intracellular calcium, such as, for example, store-operated
calcium entry, thus, can be one that provides for or participates
in an aspect of intracellular calcium or intracellular calcium
regulation. For example, a protein that provides for store-operated
calcium entry can be a STIM protein and/or an Orai protein.
[0804] As used herein, a protein that is a component of a calcium
channel is a protein that participates in multi-protein complex
that forms the channel.
[0805] As used herein, "basal" or "resting" with reference to
cytosolic calcium levels refers to the concentration of calcium in
the cytoplasm of a cell, such as, for example, an unstimulated
cell, that has not been subjected to a condition that results in
movement of calcium into or out of the cell or within the cell. The
basal or resting cytosolic calcium level can be the concentration
of free calcium (i.e., calcium that is not bound to a cellular
calcium-binding substance) in the cytoplasm of a cell, such as, for
example, an unstimulated cell, that has not been subjected to a
condition that results in movement of calcium into or out of the
cell.
[0806] As used herein, "movement" with respect to ions, including
cations, e.g., calcium, refers to movement or relocation, such as
for example flux, of ions into, out of, or within a cell. Thus,
movement of ions can be, for example, movement of ions from the
extracellular medium into a cell, from within a cell to the
extracellular medium, from within an intracellular organelle or
storage site to the cytosol, from the cytosol into an intracellular
organelle or storage site, from one intracellular organelle or
storage site to another intracellular organelle or storage site,
from the extracellular medium into an intracellular organelle or
storage site, from an intracellular organelle or storage site to
the extracellular medium and from one location to another within
the cell cytoplasm.
[0807] As used herein, "cation entry" or "calcium entry" into a
cell refers to entry of cations, such as calcium, into an
intracellular location, such as the cytoplasm of a cell or into the
lumen of an intracellular organelle or storage site. Thus, cation
entry can be, for example, the movement of cations into the cell
cytoplasm from the extracellular medium or from an intracellular
organelle or storage site, or the movement of cations into an
intracellular organelle or storage site from the cytoplasm or
extracellular medium. Movement of calcium into the cytoplasm from
an intracellular organelle or storage site is also referred to as
"calcium release" from the organelle or storage site.
[0808] As used herein, "protein that modulates intracellular
calcium" refers to any cellular protein that is involved in
regulating, controlling and/or altering intracellular calcium. For
example, such a protein can be involved in altering or adjusting
intracellular calcium in a number of ways, including, but not
limited to, through the maintenance of resting or basal cytoplasmic
calcium levels, or through involvement in a cellular response to a
signal that is transmitted in a cell through a mechanism that
includes a deviation in intracellular calcium from resting or basal
states. In the context of a "protein that modulates intracellular
calcium," a "cellular" protein is one that is associated with a
cell, such as, for example, a cytoplasmic protein, a plasma
membrane-associated protein or an intracellular membrane protein.
Proteins that modulate intracellular calcium include, but are not
limited to, ion transport proteins, calcium-binding proteins and
regulatory proteins that regulate ion transport proteins.
[0809] As used herein, "amelioration" refers to an improvement in a
disease or condition or at least a partial relief of symptoms
associated with a disease or condition.
[0810] As used herein, "cell response" refers to any cellular
response that results from ion movement into or out of a cell or
within a cell. The cell response may be associated with any
cellular activity that is dependent, at least in part, on ions such
as, for example, calcium. Such activities may include, for example,
cellular activation, gene expression, endocytosis, exocytosis,
cellular trafficking and apoptotic cell death.
[0811] As used herein, "immune cells" include cells of the immune
system and cells that perform a function or activity in an immune
response, such as, but not limited to, T-cells, B-cells,
lymphocytes, macrophages, dendritic cells, neutrophils,
eosinophils, basophils, mast cells, plasma cells, white blood
cells, antigen presenting cells and natural killer cells.
[0812] As used herein, "cytokine" refers to small soluble proteins
secreted by cells that can alter the behavior or properties of the
secreting cell or another cell. Cytokines bind to cytokine
receptors and trigger a behavior or property within the cell, for
example, cell proliferation, death or differentiation. Exemplary
cytokines include, but are not limited to, interleukins (e.g.,
IL-2, IL-3, IL-4, IL-5, IL-6, IL-7, IL-8, IL-9, IL-10, IL-11,
IL-12, IL-13, IL-15, IL-16, IL-17, IL-18, IL-1.alpha., IL-1.beta.,
and IL-1 RA), granulocyte colony stimulating factor (G-CSF),
granulocyte-macrophage colony stimulating factor (GM-CSF),
oncostatin M, erythropoietin, leukemia inhibitory factor (LIF),
interferons, B7.1 (also known as CD80), B7.2 (also known as B70,
CD86), TNF family members (TNF-.alpha., TNF-.beta., LT-13, CD40
ligand, Fas ligand, CD27 ligand, CD30 ligand, 4-1BBL, Trail), and
MIF.
[0813] "Store operated calcium entry" or "SOCE" refers to the
mechanism by which release of calcium ions from intracellular
stores is coordinated with ion influx across the plasma
membrane.
[0814] "Selective inhibitor of SOC channel activity" means that the
inhibitor is selective for SOC channels and does not substantially
affect the activity of other types of ion channels.
[0815] "Selective inhibitor of CRAC channel activity" means that
the inhibitor is selective for CRAC channels and does not
substantially affect the activity of other types of ion channels
and/or other SOC channels.
Monitoring or Assessing Effects on Intracellular Calcium
[0816] In monitoring or assessing the effect of a compound of
Formula (I), (IA), (II), (IIA), (III), (IIIA), (IV), (IVA), (V),
(VA), (VI), (VIA), (VII), (VIIA), (VIII), (VIIIA), (IX), (IXA),
(X), (XI), (XIA), (XII), or (XIIA) on intracellular calcium in any
of the screening/identification methods described herein or
recognized in the field, a direct or indirect evaluation or
measurement of cellular (including cytosolic and intracellular
organelle or compartment) calcium and/or movement of ions into,
within or out of a cell, organelle, calcium store or portions
thereof (e.g., a membrane) can be conducted. A variety of methods
are described herein and/or recognized in the field for evaluating
calcium levels and ion movements or flux. The particular method
used and the conditions employed can depend on whether a particular
aspect of intracellular calcium is being monitored or assessed.
[0817] For example, as described herein in some embodiments,
reagents and conditions are used, for specifically evaluating
store-operated calcium entry, resting cytosolic calcium levels,
calcium buffering and calcium levels and uptake by or release from
intracellular organelles and calcium stores. The effect of a
compound of Formula (I), (IA), (II), (IIA), (III), (IIIA), (IV),
(IVA), (V), (VA), (VI), (VIA), (VII), (VIIA), (VIII), (VIIIA),
(IX), (IXA), (X), (XI), (XIA), (XII), or (XIIA) on intracellular
calcium can be monitored or assessed using, for example, a cell, an
intracellular organelle or calcium storage compartment, a membrane
(including, e.g., a detached membrane patch or a lipid bilayer) or
a cell-free assay system (e.g., outside-out membrane vesicle).
Generally, some aspect of intracellular calcium is monitored or
assessed in the presence of test agent and compared to a control,
e.g., intracellular calcium in the absence of test agent.
Methods of Modulating Intracellular Calcium
[0818] Modulation of intracellular calcium can be any alteration or
adjustment in intracellular calcium including but not limited to
alteration of calcium concentration or level in the cytoplasm
and/or intracellular calcium storage organelles, e.g., endoplasmic
reticulum, alteration in the movement of calcium into, out of and
within a cell or intracellular calcium store or organelle,
alteration in the location of calcium within a cell, and alteration
of the kinetics, or other properties, of calcium fluxes into, out
of and within cells. In particular embodiments, intracellular
calcium modulation can involve alteration or adjustment, e.g.
reduction or inhibition, of store-operated calcium entry, cytosolic
calcium buffering, calcium levels in or movement of calcium into,
out of or within an intracellular calcium store or organelle,
and/or basal or resting cytosolic calcium levels. In some
embodiments, modulation of intracellular calcium can involve an
alteration or adjustment in receptor-mediated ion (e.g., calcium)
movement, second messenger-operated ion (e.g., calcium) movement,
calcium influx into or efflux out of a cell, and/or ion (e.g.,
calcium) uptake into or release from intracellular compartments,
including, for example, endosomes and lysosomes.
[0819] In one aspect, compounds described herein modulate
intracellular calcium, such as but not limited to, modulation (e.g.
reduction or inhibition) of SOC channel activity, such as
inhibition of CRAC channel activity (e.g. inhibition of I.sub.CRAC,
inhibition of SOCE) in an immune system cell (e.g., a lymphocyte,
white blood cell, T cell, B cell), a fibroblast (or a cell derived
from a fibroblast), or an epidermal, dermal or skin cell (e.g., a
keratinocyte). The step of modulating one or more proteins involved
in modulating intracellular calcium (e.g. a STIM protein and/or
Orai protein) can involve, for example, reducing the level,
expression of, an activity of, function of and/or molecular
interactions of a protein. For instance, if a cell exhibits an
increase in calcium levels or lack of regulation of an aspect of
intracellular calcium modulation, e.g., store-operated calcium
entry, then modulating may involve reducing the level of,
expression of, an activity or function of, or a molecular
interaction of a protein, e.g. a STIM protein and/or Orai
protein.

polyethylene glycol, waxes, sodium alginate, and the like.
[0837] In general, binder levels of 20-70% are used in
powder-filled gelatin capsule formulations. Binder usage level in
tablet formulations varies whether direct compression, wet
granulation, roller compaction, or usage of other excipients such
as fillers which itself can act as moderate binder. In some
embodiments, formulators determine the binder level for the
formulations, but binder usage level of up to 70% in tablet
formulations is common.

additives should be taken as merely exemplary, and not limiting, of
the types of additives that can be included in solid dosage forms
of the pharmaceutical compositions described herein.
[0845] In other embodiments, one or more layers of the
pharmaceutical formulation are plasticized. Illustratively, a

[0847] A capsule may be prepared, for example, by placing the bulk
blend of the formulation of the compound described above, inside of
a capsule. In some embodiments, the formulations (non-aqueous
suspensions and solutions) are placed in a soft gelatin capsule. In
other embodiments, the formulations are placed in standard gelatin
capsules or non-gelatin capsules such as capsules comprising HPMC.
In other embodiments, the formulation is placed in a sprinkle
capsule, wherein the capsule may be swallowed whole or the capsule
may be opened and the contents sprinkled on food prior to eating.
In some embodiments, the therapeutic dose is split into multiple
(e.g., two, three, or four) capsules. In some embodiments, the
entire dose of the formulation is delivered in a capsule form.
[0848] In various embodiments, the particles of the compound of
Formulas (I), (IA), (II), (IIA), (III), (IIIA), (IV), (IVA), (V),
(VA), (VI), (VIA), (VII), (VIIA), (VIII), (VIIIA), (IX), (IXA),
(X), (XI), (XIA), (XII), or (XIIA) described herein and one or more
excipients are dry blended and compressed into a mass, such as a
tablet, having a hardness sufficient to provide a pharmaceutical
composition that substantially disintegrates within less than about
30 minutes, less than about 35 minutes, less than about 40 minutes,
less than about 45 minutes, less than about 50 minutes, less than
about 55 minutes, or less than about 60 minutes, after oral
administration, thereby releasing the formulation into the
gastrointestinal fluid.
[0849] In another aspect, dosage forms may include
microencapsulated formulations. In some embodiments, one or more
other compatible materials are present in the microencapsulation
material. Exemplary materials include, but are not limited to, pH
modifiers, erosion facilitators, anti-foaming agents, antioxidants,
flavoring agents, and carrier materials such as binders, suspending
agents, disintegration agents, filling agents, surfactants,
solubilizers, stabilizers, lubricants, wetting agents, and
diluents.
[0850] Materials useful for the microencapsulation described herein
include materials compatible with compounds described herein, which
sufficiently isolate the compound from other non-compatible
excipients. Materials compatible with compounds described herein
are those that delay the release of the compounds of Formulas (I),
(IA), (II), (IIA), (III), (IIIA), (IV), (IVA), (V), (VA), (VI),
(VIA), (VII), (VIIA), (VIII), (VIIIA), (IX), (IXA), (X), (XI),
(XIA), (XII), or (XIIA) in vivo.
[0851] Exemplary microencapsulation materials useful for delaying
the release of the formulations including compounds described
herein, include, but are not limited to, hydroxypropyl cellulose
ethers (HPC) such as Klucel.RTM. or Nisso HPC, low-substituted
hydroxypropyl cellulose ethers (L-HPC), hydroxypropyl methyl
cellulose ethers (HPMC) such as Seppifilm-LC, Pharmacoat.RTM.,
Metolose SR, Methocel.RTM.-E, Opadry YS, PrimaFlo, Benecel MP824,
and Benecel MP843, methylcellulose polymers such as
Methocel.RTM.-A, hydroxypropylmethylcellulose acetate stearate

carboxymethylcelluloses and salts of carboxymethylcelluloses (CMC)
such as Aqualon.RTM.-CMC, polyvinyl alcohol and polyethylene glycol
co-polymers such as Kollicoat IR.RTM., monoglycerides (Myverol),
triglycerides (KLX), polyethylene glycols, modified food starch,
acrylic polymers and mixtures of acrylic polymers with cellulose
ethers such as Eudragit.RTM. EPO, Eudragit.RTM. L30D-55,
Eudragit.RTM. FS 30D Eudragit.RTM. L100-55, Eudragit.RTM. L100,

[0852] In still other embodiments, plasticizers such as
polyethylene glycols, e.g., PEG 300, PEG 400, PEG 600, PEG 1450,
PEG 3350, and PEG 800, stearic acid, propylene glycol, oleic acid,
and triacetin are incorporated into the microencapsulation
material. In other embodiments, the microencapsulating material
useful for delaying the release of the pharmaceutical compositions
is from the USP or the National Formulary (NF). In yet other
embodiments, the microencapsulation material is Klucel. In still
other embodiments, the microencapsulation material is methocel.
[0853] Microencapsulated compounds described herein may be
formulated by methods that include, e.g., spray drying processes,
spinning disk-solvent processes, hot melt processes, spray chilling
methods, fluidized bed, electrostatic deposition, centrifugal
extrusion, rotational suspension separation, polymerization at
liquid-gas or solid-gas interface, pressure extrusion, or spraying
solvent extraction bath. In addition to these, several chemical
techniques, e.g., complex coacervation, solvent evaporation,
polymer-polymer incompatibility, interfacial polymerization in
liquid media, in situ polymerization, in-liquid drying, and
desolvation in liquid media could also be used. Furthermore, other
methods such as roller compaction, extrusion/spheronization,
coacervation, or nanoparticle coating may also be used.
[0854] In still other embodiments, effervescent powders are also
prepared in accordance with the present disclosure. Effervescent
salts have been used to disperse medicines in water for oral
administration. Effervescent salts are granules or coarse powders
containing a medicinal agent in a dry mixture, usually composed of
sodium bicarbonate, citric acid and/or tartaric acid. When such
salts are added to water, the acids and the base react to liberate
carbon dioxide gas, thereby causing "effervescence." Examples of
effervescent salts include, e.g., the following ingredients: sodium
bicarbonate or a mixture of sodium bicarbonate and sodium
carbonate, citric acid and/or tartaric acid. Any acid-base
combination that results in the liberation of carbon dioxide can be
used in place of the combination of sodium bicarbonate and citric
and tartaric acids, as long as the ingredients were suitable for
pharmaceutical use and result in a pH of about 6.0 or higher.
[0855] In other embodiments, the formulations described herein,
which include a compound described herein, are solid dispersions.
Methods of producing such solid dispersions include, but are not
limited to, for example, U.S. Pat. Nos. 4,343,789, 5,340,591,
5,456,923, 5,700,485, 5,723,269, and U.S. patent publication no.
2004/0013734. In still other embodiments, the formulations
described herein are solid solutions. Solid solutions incorporate a
substance together with the active agent and other excipients such
that heating the mixture results in dissolution of the drug and the
resulting composition is then cooled to provide a solid blend which
can be further formulated or directly added to a capsule or
compressed into a tablet. Methods of producing such solid solutions
include, but are not limited to, for example, U.S. Pat. Nos.
4,151,273, 5,281,420, and 6,083,518.
[0856] The pharmaceutical solid oral dosage forms including
formulations described herein, which include a compounds described
herein, can be further formulated to provide a controlled release
of the compound of Formulas (I), (IA), (II), (IIA), (III), (IIIA),
(IV), (IVA), (V), (VA), (VI), (VIA), (VII), (VIIA), (VIII),
(VIIIA), (IX), (IXA), (X), (XI), (XIA), (XII), or (XIIA).
Controlled release refers to the release of the compounds described
herein from a dosage form in which it is incorporated according to
a desired profile over an extended period of time. Controlled
release profiles include, for example, sustained release, prolonged
release, pulsatile release, and delayed release profiles. In
contrast to immediate release compositions, controlled release
compositions allow delivery of an agent to a subject over an
extended period of time according to a predetermined profile. Such
release rates can provide therapeutically effective levels of agent
for an extended period of time and thereby provide a longer period
of pharmacologic response while minimizing side effects as compared
to conventional rapid release dosage forms. Such longer periods of
response provide for many inherent benefits that are not achieved
with the corresponding short acting, immediate release
preparations.
[0857] In some embodiments, the solid dosage forms described herein
can be formulated as enteric coated delayed release oral dosage
forms, i.e., as an oral dosage form of a pharmaceutical composition
as described herein which utilizes an enteric coating to affect
release in the small intestine of the gastrointestinal tract. The
enteric coated dosage form may be a compressed or molded or
extruded tablet/mold (coated or uncoated) containing granules,
powder, pellets, beads or particles of the active ingredient and/or
other composition components, which are themselves coated or
uncoated. The enteric coated oral dosage form may also be a capsule
(coated or uncoated) containing pellets, beads or granules of the
solid carrier or the composition, which are themselves coated or
uncoated.
[0858] The term "delayed release" as used herein refers to the
delivery so that the release can be accomplished at some generally
predictable location in the intestinal tract more distal to that
which would have been accomplished if there had been no delayed
release alterations. In some embodiments the method for delay of
release is coating. Any coatings should be applied to a sufficient
thickness such that the entire coating does not dissolve in the
gastrointestinal fluids at pH below about 5, but does dissolve at
pH about 5 and above. Coatings may be made from:
[0859] Acrylic polymers. The performance of acrylic polymers
(primarily their solubility in biological fluids) can vary based on
the degree and type of substitution. Examples of suitable acrylic
polymers include methacrylic acid copolymers and ammonium
methacrylate copolymers. The Eudragit series E, L, S, RL, RS and NE
(Rohm Pharma) are available as solubilized in organic solvent,
aqueous dispersion, or dry powders. The Eudragit series RL, NE, and
RS are insoluble in the gastrointestinal tract but are permeable
and are used primarily for colonic targeting. The Eudragit series E
dissolve in the stomach. The Eudragit series L, L-30D and S are
insoluble in stomach and dissolve in the intestine;
[0860] Cellulose Derivatives. Examples of suitable cellulose
derivatives are: ethyl cellulose; reaction mixtures of partial
acetate esters of cellulose with phthalic anhydride. The
performance can vary based on the degree and type of substitution.
Cellulose acetate phthalate (CAP) dissolves in pH >6. Aquateric
(FMC) is an aqueous based system and is a spray dried CAP
pseudolatex with particles <1 .mu.m. Other components in
Aquateric can include pluronics, Tweens, and acetylated
monoglycerides. Other suitable cellulose derivatives include:
cellulose acetate trimellitate (Eastman); methylcellulose
(Pharmacoat, Methocel); hydroxypropylmethyl cellulose phthalate
(HPMCP); hydroxypropylmethyl cellulose succinate (HPMCS); and
hydroxypropylmethylcellulose acetate succinate (e.g., AQOAT (Shin
Etsu)). The performance can vary based on the degree and type of
substitution. For example, HPMCP such as, HP-50, HP-55, HP-55S,
HP-55F grades are suitable. The performance can vary based on the
degree and type of substitution. For example, suitable grades of
hydroxypropylmethylcellulose acetate succinate include, but are not
limited to, AS-LG (LF), which dissolves at pH 5, AS-MG (MF), which
dissolves at pH 5.5, and AS-HG (HF), which dissolves at higher pH.
These polymers are offered as granules, or as fine powders for
aqueous dispersions;
[0861] Poly Vinyl Acetate Phthalate (PVAP). PVAP dissolves in pH
>5, and it is much less permeable to water vapor and gastric
fluids.
[0862] In some embodiments, the coating can, and usually does,
contain a plasticizer and possibly other coating excipients such as
colorants, talc, and/or magnesium stearate. Suitable plasticizers
include triethyl citrate (Citroflex 2), triacetin (glyceryl
triacetate), acetyl triethyl citrate (Citroflec A2), Carbowax 400
(polyethylene glycol 400), diethyl phthalate, tributyl citrate,
acetylated monoglycerides, glycerol, fatty acid esters, propylene
glycol, and dibutyl phthalate. In particular, anionic carboxylic
acrylic polymers usually will contain 10-25% by weight of a
plasticizer, especially dibutyl phthalate, polyethylene glycol,
triethyl citrate and triacetin. Conventional coating techniques
such as spray or pan coating are employed to apply coatings. The
coating thickness must be sufficient to ensure that the oral dosage
form remains intact until the desired site of topical delivery in
the intestinal tract is reached.
[0863] Colorants, detackifiers, surfactants, antifoaming agents,
lubricants (e.g., carnuba wax or PEG) may be added to the coatings
besides plasticizers to solubilize or disperse the coating
material, and to improve coating performance and the coated
product.
[0864] In other embodiments, the formulations described herein,
which include a compound of Formulas (I), (IA), (II), (IIA), (III),
(IIIA), (IV), (IVA), (V), (VA), (VI), (VIA), (VII), (VIIA), (VIII),
(VIIIA), (IX), (IXA), (X), (XI), (XIA), (XII), or (XIIA) described
herein, are delivered using a pulsatile dosage form. A pulsatile
dosage form is capable of providing one or more immediate release
pulses at predetermined time points after a controlled lag time or
at specific sites. Pulsatile dosage forms may be administered using
a variety of pulsatile formulations including, but are not limited
to, those described in U.S. Pat. Nos. 5,011,692; 5,017,381;
5,229,135; 5,840,329; 4,871,549; 5,260,068; 5,260,069; 5,508,040;
5,567,441 and 5,837,284.
[0865] Many other types of controlled release systems are suitable
for use with the formulations described herein. Examples of such
delivery systems include, e.g., polymer-based systems, such as
polylactic and polyglycolic acid, polyanhydrides and
polycaprolactone; porous matrices, nonpolymer-based systems that
are lipids, including sterols, such as cholesterol, cholesterol
esters and fatty acids, or neutral fats, such as mono-, di- and
triglycerides; hydrogel release systems; silastic systems;
peptide-based systems; wax coatings, bioerodible dosage forms,
compressed tablets using conventional binders and the like. See,
e.g., Liberman et al., Pharmaceutical Dosage Forms, 2 Ed., Vol. 1,
pp. 209-214 (1990); Singh et al., Encyclopedia of Pharmaceutical
Technology, 2nd Ed., pp. 751-753 (2002); U.S. Pat. Nos. 4,327,725;
4,624,848; 4,968,509; 5,461,140; 5,456,923; 5,516,527; 5,622,721;
5,686,105; 5,700,410; 5,977,175; 6,465,014; and 6,932,983.
[0866] In some embodiments, pharmaceutical formulations are
provided that include particles of the compounds described herein,
e.g. compounds of Formulas (I), (IA), (II), (IIA), (III), (IIIA),
(IV), (IVA), (V), (VA), (VI), (VIA), (VII), (VIIA), (VIII),
(VIIIA), (IX), (IXA), (X), (XI), (XIA), (XII), or (XIIA), and at
least one dispersing agent or suspending agent for oral
administration to a subject. The formulations may be a powder
and/or granules for suspension, and upon admixture with water, a
substantially uniform suspension is obtained.
[0867] Liquid formulation dosage forms for oral administration can
be aqueous suspensions selected from the group including, but not
limited to, pharmaceutically acceptable aqueous oral dispersions,
emulsions, solutions, elixirs, gels, and syrups. See, e.g., Singh
et al., Encyclopedia of Pharmaceutical Technology, 2nd Ed., pp.
754-757 (2002).
[0868] The aqueous suspensions and dispersions described herein can
remain in a homogenous state, as defined in The USP Pharmacists'
Pharmacopeia (2005 edition, chapter 905), for at least 4 hours. The
homogeneity should be determined by a sampling method consistent
with regard to determining homogeneity of the entire composition.
In one embodiment, an aqueous suspension can be re-suspended into a
homogenous suspension by physical agitation lasting less than 1
minute. In another embodiment, an aqueous suspension can be
re-suspended into a homogenous suspension by physical agitation
lasting less than 45 seconds. In yet another embodiment, an aqueous
suspension can be re-suspended into a homogenous suspension by
physical agitation lasting less than 30 seconds. In still another
embodiment, no agitation is necessary to maintain a homogeneous
aqueous dispersion.
[0869] The pharmaceutical compositions described herein may include
sweetening agents such as, but not limited to, acacia syrup,
acesulfame K, alitame, anise, apple, aspartame, banana, Bavarian
cream, berry, black currant, butterscotch, calcium citrate,
camphor, caramel, cherry, cherry cream, chocolate, cinnamon, bubble
gum, citrus, citrus punch, citrus cream, cotton candy, cocoa, cola,
cool cherry, cool citrus, cyclamate, cylamate, dextrose,
eucalyptus, eugenol, fructose, fruit punch, ginger,
glycyrrhetinate, glycyrrhiza (licorice) syrup, grape, grapefruit,
honey, isomalt, lemon, lime, lemon cream, monoammonium
glyrrhizinate (MagnaSweet.RTM.), maltol, mannitol, maple,
marshmallow, menthol, mint cream, mixed berry, neohesperidine DC,

Prosweet.RTM. Powder, raspberry, root beer, rum, saccharin,
safrole, sorbitol, spearmint, spearmint cream, strawberry,
strawberry cream, stevia, sucralose, sucrose, sodium saccharin,
saccharin, aspartame, acesulfame potassium, mannitol, talin,
sucralose, sorbitol, swiss cream, tagatose, tangerine, thaumatin,
tutti fruitti, vanilla, walnut, watermelon, wild cherry,
wintergreen, xylitol, or any combination of these flavoring
ingredients, e.g., anise-menthol, cherry-anise, cinnamon-orange,
cherry-cinnamon, chocolate-mint, honey-lemon, lemon-lime,
lemon-mint, menthol-eucalyptus, orange-cream, vanilla-mint, and
mixtures thereof.
[0870] In some embodiments, the pharmaceutical formulations
described herein can be self-emulsifying drug delivery systems
(SEDDS). Emulsions are dispersions of one immiscible phase in
another, usually in the form of droplets. Generally, emulsions are
created by vigorous mechanical dispersion. SEDDS, as opposed to
emulsions or microemulsions, spontaneously form emulsions when
added to an excess of water without any external mechanical
dispersion or agitation. An advantage of SEDDS is that only gentle
mixing is required to distribute the droplets throughout the
solution. Additionally, water or the aqueous phase can be added
just prior to administration, which ensures stability of an
unstable or hydrophobic active ingredient. Thus, the SEDDS provides
an effective delivery system for oral and parenteral delivery of
hydrophobic active ingredients. SEDDS may provide improvements in
the bioavailability of hydrophobic active ingredients. Methods of
producing self-emulsifying dosage forms include, but are not
limited to, for example, U.S. Pat. Nos. 5,858,401, 6,667,048, and
6,960,563.
[0871] There is overlap between the above-listed additives used in
the aqueous dispersions or suspensions described herein, since a
given additive is often classified differently by different
practitioners in the field, or is commonly used for any of several
different functions. Thus, the above-listed additives should be
taken as merely exemplary, and not limiting, of the types of
additives that can be included in formulations described
herein.
[0872] Potential excipients for intranasal formulations include,
for example, U.S. Pat. Nos. 4,476,116, 5,116,817 and 6,391,452.
Formulations solutions in saline, employing benzyl alcohol or other
suitable preservatives, fluorocarbons, and/or other solubilizing or
dispersing agents. See, for example, Ansel, H. C. et al.,
Pharmaceutical Dosage Forms and Drug Delivery Systems, Sixth Ed.
(1995). Preferably these compositions and formulations are prepared
with suitable nontoxic pharmaceutically acceptable ingredients. The
choice of suitable carriers is highly dependent upon the exact
nature of the nasal dosage form desired, e.g., solutions,
suspensions, ointments, or gels. Nasal dosage forms generally
contain large amounts of water in addition to the active
ingredient. Minor amounts of other ingredients such as pH
adjusters, emulsifiers or dispersing agents, preservatives,
surfactants, gelling agents, or buffering and other stabilizing and
solubilizing agents may also be present. Preferably, the nasal
dosage form should be isotonic with nasal secretions.
[0873] For administration by inhalation, the compounds described
herein may be in a form as an aerosol, a mist or a powder.
Pharmaceutical compositions described herein are conveniently
delivered in the form of an aerosol spray presentation from
pressurized packs or a nebuliser, with the use of a suitable
propellant, e.g., dichlorodifluoromethane, trichlorofluoromethane,
dichlorotetrafluoroethane, carbon dioxide or other suitable gas. In
the case of a pressurized aerosol, the dosage unit may be
determined by providing a valve to deliver a metered amount.
Capsules and cartridges of, such as, by way of example only,
gelatin for use in an inhaler or insufflator may be formulated
containing a powder mix of the compound described herein and a
suitable powder base such as lactose or starch.
[0874] Buccal formulations that include compounds described herein
may be administered using a variety of formulations which include,
but are not limited to, U.S. Pat. Nos. 4,229,447, 4,596,795,
4,755,386, and 5,739,136. In addition, the buccal dosage forms
described herein can further include a bioerodible (hydrolysable)
polymeric carrier that also serves to adhere the dosage form to the
buccal mucosa. The buccal dosage form is fabricated so as to erode
gradually over a predetermined time period, wherein the delivery of
the compound is provided essentially throughout. Buccal drug
delivery avoids the disadvantages encountered with oral drug
administration, e.g., slow absorption, degradation of the active
agent by fluids present in the gastrointestinal tract and/or
first-pass inactivation in the liver. With regard to the
bioerodible (hydrolysable) polymeric carrier, virtually any such
carrier can be used, so long as the desired drug release profile is
not compromised, and the carrier is compatible with the compounds
described herein, and any other components that may be present in
the buccal dosage unit. Generally, the polymeric carrier comprises
hydrophilic (water-soluble and water-swellable) polymers that
adhere to the wet surface of the buccal mucosa. Examples of
polymeric carriers useful herein include acrylic acid polymers and
co, e.g., those known as "carbomers" (Carbopol.RTM., which may be
obtained from B.F. Goodrich, is one such polymer). Other components
may also be incorporated into the buccal dosage forms described
herein include, but are not limited to, disintegrants, diluents,
binders, lubricants, flavoring, colorants, preservatives, and the
like. For buccal or sublingual administration, the compositions may
take the form of tablets, lozenges, or gels formulated in a
conventional manner.
[0875] Transdermal formulations described herein may be
administered using a variety of devices including but not limited
to, U.S. Pat. Nos. 3,598,122, 3,598,123, 3,710,795, 3,731,683,
3,742,951, 3,814,097, 3,921,636, 3,972,995, 3,993,072, 3,993,073,
3,996,934, 4,031,894, 4,060,084, 4,069,307, 4,077,407, 4,201,211,
4,230,105, 4,292,299, 4,292,303, 5,336,168, 5,665,378, 5,837,280,
5,869,090, 6,923,983, 6,929,801 and 6,946,144.
[0876] The transdermal dosage forms described herein may
incorporate certain pharmaceutically acceptable excipients which
are conventional in the art. In one embodiment, the transdermal
formulations described herein include at least three components:
(1) a formulation of a compound of Formulas (I), (IA), (II), (IIA),
(III), (IIIA), (IV), (IVA), (V), (VA), (VI), (VIA), (VII), (VIIA),
(VIII), (VIIIA), (IX), (IXA), (X), (XI), (XIA), (XII), or (XIIA);
(2) a penetration enhancer; and (3) an aqueous adjuvant. In
addition, transdermal formulations can include additional
components such as, but not limited to, gelling agents, creams and
ointment bases, and the like. In some embodiments, the transdermal
formulation can further include a woven or non-woven backing
material to enhance absorption and prevent the removal of the
transdermal formulation from the skin. In other embodiments, the
transdermal formulations described herein can maintain a saturated
or supersaturated state to promote diffusion into the skin.
[0877] Formulations suitable for transdermal administration of
compounds described herein may employ transdermal delivery devices
and transdermal delivery patches and can be lipophilic emulsions or
buffered, aqueous solutions, dissolved and/or dispersed in a
polymer or an adhesive. Such patches may be constructed for
continuous, pulsatile, or on demand delivery of pharmaceutical
agents. Still further, transdermal delivery of the compounds
described herein can be accomplished by means of iontophoretic
patches and the like. Additionally, transdermal patches can provide
controlled delivery of the compounds described herein. The rate of
absorption can be slowed by using rate-controlling membranes or by
trapping the compound within a polymer matrix or gel. Conversely,
absorption enhancers can be used to increase absorption. An
absorption enhancer or carrier can include absorbable
pharmaceutically acceptable solvents to assist passage through the
skin. For example, transdermal devices are in the form of a bandage
comprising a backing member, a reservoir containing the compound
optionally with carriers, optionally a rate controlling barrier to
deliver the compound to the skin of the host at a controlled and
predetermined rate over a prolonged period of time, and means to
secure the device to the skin.
[0878] Formulations suitable for intramuscular, subcutaneous, or
intravenous injection may include physiologically acceptable
sterile aqueous or non-aqueous solutions, dispersions, suspensions
or emulsions, and sterile powders for reconstitution into sterile
injectable solutions or dispersions. Examples of suitable aqueous
and non-aqueous carriers, diluents, solvents, or vehicles including
water, ethanol, polyols (propyleneglycol, polyethylene-glycol,
glycerol, cremophor and the like), suitable mixtures thereof,
vegetable oils (such as olive oil) and injectable organic esters
such as ethyl oleate. Proper fluidity can be maintained, for
example, by the use of a coating such as lecithin, by the
maintenance of the required particle size in the case of
dispersions, and by the use of surfactants. Formulations suitable
for subcutaneous injection may also contain additives such as
preserving, wetting, emulsifying, and dispensing agents. Prevention
of the growth of microorganisms can be ensured by various
antibacterial and antifungal agents, such as parabens,
chlorobutanol, phenol, sorbic acid, and the like. It may also be
desirable to include isotonic agents, such as sugars, sodium
chloride, and the like. Prolonged absorption of the injectable
pharmaceutical form can be brought about by the use of agents
delaying absorption, such as aluminum monostearate and gelatin.
[0879] For intravenous injections, compounds described herein may
be formulated in aqueous solutions, preferably in physiologically
compatible buffers such as Hank's solution, Ringer's solution, or
physiological saline buffer. For transmucosal administration,
penetrants appropriate to the barrier to be permeated are used in
the formulation. Such penetrants are generally recognized in the
field. For other parenteral injections, appropriate formulations
may include aqueous or nonaqueous solutions, preferably with
physiologically compatible buffers or excipients. Such excipients
are generally recognized in the field.
[0880] Parenteral injections may involve bolus injection or
continuous infusion. Formulations for injection may be presented in
unit dosage form, e.g., in ampoules or in multi-dose containers,
with an added preservative. The pharmaceutical composition
described herein may be in a form suitable for parenteral injection
as a sterile suspensions, solutions or emulsions in oily or aqueous
vehicles, and may contain formulatory agents such as suspending,
stabilizing and/or dispersing agents. Pharmaceutical formulations
for parenteral administration include aqueous solutions of the
active compounds in water-soluble form. Additionally, suspensions
of the active compounds may be prepared as appropriate oily
injection suspensions. Suitable lipophilic solvents or vehicles
include fatty oils such as sesame oil, or synthetic fatty acid
esters, such as ethyl oleate or triglycerides, or liposomes.
Aqueous injection suspensions may contain substances which increase
the viscosity of the suspension, such as sodium carboxymethyl
cellulose, sorbitol, or dextran. Optionally, the suspension may
also contain suitable stabilizers or agents which increase the
solubility of the compounds to allow for the preparation of highly
concentrated solutions. Alternatively, the active ingredient may be
in powder form for constitution with a suitable vehicle, e.g.,
sterile pyrogen-free water, before use.
[0881] In certain embodiments, delivery systems for pharmaceutical
compounds may be employed, such as, for example, liposomes and
emulsions. In certain embodiments, compositions provided herein
also include an mucoadhesive polymer, selected from among, for
example, carboxymethylcellulose, carbomer (acrylic acid polymer),
poly(methylmethacrylate), polyacrylamide, polycarbophil, acrylic
acid/butyl acrylate copolymer, sodium alginate and dextran.
[0882] In some embodiments, the compounds described herein may be
administered topically and are formulated into a variety of
topically administrable compositions, such as solutions,
suspensions, lotions, gels, pastes, medicated sticks, balms, creams
or ointments. Such pharmaceutical compounds can contain
solubilizers, stabilizers, tonicity enhancing agents, buffers and
preservatives.
[0883] The compounds described herein may also be formulated in
rectal compositions such as enemas, rectal gels, rectal foams,
rectal aerosols, suppositories, jelly suppositories, or retention
enemas, containing conventional suppository bases such as cocoa
butter or other glycerides, as well as synthetic polymers such as
polyvinylpyrrolidone, PEG, and the like. In suppository forms of
the compositions, a low-melting wax such as, but not limited to, a
mixture of fatty acid glycerides, optionally in combination with
cocoa butter is first melted.
[0884] Generally, an agent, such as a compound of Formulas (I),
(IA), (II), (IIA), (III), (IIIA), (IV), (IVA), (V), (VA), (VI),
(VIA), (VII), (VIIA), (VIII), (VIIIA), (IX), (IXA), (X), (XI),
(XIA), (XII), or (XIIA) is administered in an amount effective for
amelioration of, or prevention of the development of symptoms of,
the disease or disorder (i.e., a therapeutically effective amount).
Thus, a therapeutically effective amount can be an amount that is
capable of at least partially preventing or reversing a disease or
disorder. The dose required to obtain an effective amount may vary
depending on the agent, formulation, disease or disorder, and
individual to whom the agent is administered.
[0885] Determination of effective amounts may also involve in vitro
assays in which varying doses of agent are administered to cells in
culture and the concentration of agent effective for ameliorating
some or all symptoms is determined in order to calculate the
concentration required in vivo. Effective amounts may also be based
in in vivo animal studies.
[0886] An agent can be administered prior to, concurrently with and
subsequent to the appearance of symptoms of a disease or disorder.
In some embodiments, an agent is administered to a subject with a
family history of the disease or disorder, or who has a phenotype
that may indicate a predisposition to a disease or disorder, or who
has a genotype which predisposes the subject to the disease or
disorder.
[0887] The particular delivery system used can depend on a number
of factors, including, for example, the intended target and the
route of administration, e.g., local or systemic. Targets for
delivery can be specific cells which are causing or contributing to
a disease or disorder, including, for example, cells that have
altered intracellular calcium or calcium dysregulation or
dyshomeostasis, and cells that do not have altered intracellular
calcium but that may have some alteration, defect or deficiency
that can be, at least in part, compensated, counteracted, reversed
or alleviated or eliminated by altering intracellular calcium of
the cell. Particular cells include, for example, immune cells
(e.g., lymphocytes, T cells, B cells, white blood cells),
fibroblasts (or cells derived from a fibroblast), epidermal, dermal
or skin cells (e.g., a keratinocytes), blood cells, kidney or renal
cells (e.g., mesangial cells), muscle cells (e.g., a smooth muscle
cell such as an airway (tracheal or bronchial) smooth muscle cell)
and exocrine or secretory (e.g., salivary, including parotid acinar
and submandibular gland) cells. For example, a target cell can be
resident or infiltrating cells in the lungs or airways that
contribute to an asthmatic illness or disease, resident or
infiltrating cells in the nervous system contributing to a
neurological, neurodegenerative or demyelinating disease or
disorder, resident or infiltrating cells involved in rejection of a
kidney graft, grafted cells that when activated lead to
graft-versus-host disease, resident or infiltrating cells involved
in rejection of a kidney graft, resident or infiltrating cells,
activation of which contributes to inflammation, e.g., in
arthritis, resident or infiltrating cells in the kidney or renal
system (e.g., mesangial cells) involved in neuropathy and
glomerulonephritis and resident or infiltrating cells in exocrine
glands (e.g., salivary and lacrimal glands) involved in autoimmune
disorders (e.g., Sjogren's disease). Administration of an agent can
be directed to one or more cell types or subsets of a cell type by
methods recognized in the field. For example, an agent can be
coupled to an antibody, ligand to a cell surface receptor or a
toxin, or can be contained in a particle that is selectively
internalized into cells, e.g., liposomes or a virus in which the
viral receptor binds specifically to a certain cell type, or a
viral particle lacking the viral nucleic acid, or can be
administered locally.
Examples of Methods of Dosing and Treatment Regimens
[0888] The compounds described herein can be used in the
preparation of medicaments for the modulation of intracellular
calcium, or for the treatment of diseases or conditions that would
benefit, at least in part, from modulation of intracellular
calcium. In addition, a method for treating any of the diseases or
conditions described herein in a subject in need of such treatment,
involves administration of pharmaceutical compositions containing
at least one compound described herein, or a pharmaceutically
acceptable salt, pharmaceutically acceptable prodrug, or
pharmaceutically acceptable solvate thereof, in therapeutically
effective amounts to said subject.
[0889] The compositions containing the compound(s) described herein
can be administered for prophylactic and/or therapeutic treatments.
In therapeutic applications, the compositions are administered to a
patient already suffering from a disease or condition, in an amount
sufficient to cure or at least partially arrest the symptoms of the
disease or condition. Amounts effective for this use will depend on
the severity and course of the disease or condition, previous
therapy, the patient's health status, weight, and response to the
drugs, and the judgment of the treating physician.
[0890] In prophylactic applications, compositions containing the
compounds described herein are administered to a patient
susceptible to or otherwise at risk of a particular disease,
disorder or condition. Such an amount is defined to be a
"prophylactically effective amount or dose." In this use, the
precise amounts also depend on the patient's state of health,
weight, and the like. When used in a patient, effective amounts for
this use will depend on the severity and course of the disease,
disorder or condition, previous therapy, the patient's health
status and response to the drugs, and the judgment of the treating
physician.
[0891] In the case wherein the patient's condition does not
improve, upon the doctor's discretion the administration of the
compounds may be administered chronically, that is, for an extended
period of time, including throughout the duration of the patient's
life in order to ameliorate or otherwise control or limit the
symptoms of the patient's disease or condition.
[0892] In the case wherein the patient's status does improve, upon
the doctor's discretion the administration of the compounds may be
given continuously; alternatively, the dose of drug being
administered may be temporarily reduced or temporarily suspended
for a certain length of time (i.e., a "drug holiday"). The length
of the drug holiday can vary between 2 days and 1 year, including
by way of example only, 2 days, 3 days, 4 days, 5 days, 6 days, 7
days, 10 days, 12 days, 15 days, 20 days, 28 days, 35 days, 50
days, 70 days, 100 days, 120 days, 150 days, 180 days, 200 days,
250 days, 280 days, 300 days, 320 days, 350 days, or 365 days. The
dose reduction during a drug holiday may be from about 10% to about
100%, including, by way of example only, about 10%, about 15%, 0%,
a 20%, about 25%, about 30%, %, about 40%, about 35%, about 40%,
about 45%, about 50%, about 55%, about 60%, about 65%, about 70%,
about 75%, about 80%, about 85%, about 90%, about 95%, or about
100%.
[0893] Once improvement of the patient's conditions has occurred, a
maintenance dose is administered if necessary. Subsequently, the
dosage or the frequency of administration, or both, can be reduced,
as a function of the symptoms, to a level at which the improved
disease, disorder or condition is retained. Patients can, however,
require intermittent treatment on a long-term basis upon any
recurrence of symptoms.
[0894] The amount of a given agent that will correspond to such an
amount will vary depending upon factors such as the particular
compound, disease or condition and its severity, the identity
(e.g., weight) of the subject or host in need of treatment, but can
nevertheless be determined in a manner recognized in the field
according to the particular circumstances surrounding the case,
including, e.g., the specific agent being administered, the route
of administration, the condition being treated, and the subject or
host being treated. In general, however, doses employed for adult
human treatment will typically be in the range of about 0.02-about
5000 mg per day, in some embodiments, about 1-about 1500 mg per
day. The desired dose may conveniently be presented in a single
dose or as divided doses administered simultaneously (or over a
short period of time) or at appropriate intervals, for example as
two, three, four or more sub-doses per day.
[0895] The pharmaceutical composition described herein may be in
unit dosage forms suitable for single administration of precise
dosages. In unit dosage form, the formulation is divided into unit
doses containing appropriate quantities of one or more compound.
The unit dosage may be in the form of a package containing discrete
quantities of the formulation. Non-limiting examples are packaged
tablets or capsules, and powders in vials or ampoules. Aqueous
suspension compositions can be packaged in single-dose
non-reclosable containers. Alternatively, multiple-dose reclosable
containers can be used, in which case it is typical to include a
preservative in the composition. By way of example only,
formulations for parenteral injection may be presented in unit
dosage form, which include, but are not limited to ampoules, or in
multi-dose containers, with an added preservative.
[0896] The daily dosages appropriate for the compounds described
herein described herein are from about 0.01 mg/kg to about 20
mg/kg. In one embodiment, the daily dosages are from about 0.1
mg/kg to about 10 mg/kg. An indicated daily dosage in the larger
mammal, including, but not limited to, humans, is in the range from
about 0.5 mg to about 1000 mg, conveniently administered in a
single dose or in divided doses, including, but not limited to, up
to four times a day or in extended release form. Suitable unit
dosage forms for oral administration include from about 1 to about
500 mg active ingredient. In one embodiment, the unit dosage is
about 1 mg, about 5 mg, about, 10 mg, about 20 mg, about 50 mg,
about 100 mg, about 200 mg, about 250 mg, about 400 mg, or about
500 mg. The foregoing ranges are merely suggestive, as the number
of variables in regard to an individual treatment regime is large,
and considerable excursions from these recommended values are not
uncommon. Such dosages may be altered depending on a number of
variables, not limited to the activity of the compound used, the
disease or condition to be treated, the mode of administration, the
requirements of the individual subject, the severity of the disease
or condition being treated, and the judgment of the
practitioner.
[0897] Toxicity and therapeutic efficacy of such therapeutic
regimens can be determined by standard pharmaceutical procedures in
cell cultures or experimental animals, including, but not limited
to, the determination of the LD.sub.50 (the dose lethal to 50% of
the population) and the ED.sub.50 (the dose therapeutically
effective in 50% of the population). The dose ratio between the
toxic and therapeutic effects is the therapeutic index and it can
be expressed as the ratio between LD.sub.50 and ED.sub.50.
Compounds exhibiting high therapeutic indices are preferred. The
data obtained from cell culture assays and animal studies can be
used in formulating a range of dosage for use in human. The dosage
of such compounds lies preferably within a range of circulating
concentrations that include the ED.sub.50 with minimal toxicity.
The dosage may vary within this range depending upon the dosage
form employed and the route of administration utilized.
Combination Treatments
[0898] The compounds of Formulas (I), (IA), (II), (IIA), (III),
(IIIA), (IV), (IVA), (V), (VA), (VI), (VIA), (VII), (VIIA), (VIII),
(VIIIA), (IX), (IXA), (X), (XI), (XIA), (XII), or (XIIA), and
compositions thereof, may also be used in combination with other
therapeutic agents that are selected for their therapeutic value
for the condition to be treated. In general, the compositions
described herein and, in embodiments where combinational therapy is
employed, other agents do not have to be administered in the same
pharmaceutical composition, and may, because of different physical
and chemical characteristics, have to be administered by different
routes. The determination of the mode of administration and the
advisability of administration, where possible, in the same
pharmaceutical composition, is well within the knowledge of the
clinician. The initial administration can be made according to
established protocols recognized in the field, and then, based upon
the observed effects, the dosage, modes of administration and times
of administration can be modified by the clinician.
[0899] In certain instances, it may be appropriate to administer at
least one compound described herein in combination with another
therapeutic agent. By way of example only, if one of the side
effects experienced by a patient upon receiving one of the
compounds herein, such as a compound of Formulas (I), (IA), (II),
(IIA), (III), (IIIA), (IV), (IVA), (V), (VA), (VI), (VIA), (VII),
(VIIA), (VIII), (VIIIA), (IX), (IXA), (X), (XI), (XIA), (XII), or
(XIIA), is nausea, then it may be appropriate to administer an
anti-nausea agent in combination with the initial therapeutic
agent. Or, by way of example only, the therapeutic effectiveness of
one of the compounds described herein may be enhanced by
administration of an adjuvant (i.e., by itself the adjuvant may
have minimal therapeutic benefit, but in combination with another
therapeutic agent, the overall therapeutic benefit to the patient
is enhanced). Or, by way of example only, the benefit experienced
by a patient may be increased by administering one of the compounds
described herein with another therapeutic agent (which also
includes a therapeutic regimen) that also has therapeutic benefit.
In any case, regardless of the disease, disorder or condition being
treated, the overall benefit experienced by the patient may simply
be additive of the two therapeutic agents or the patient may
experience a synergistic benefit.
[0900] The particular choice of compounds used will depend upon the
diagnosis of the attending physicians and their judgment of the
condition of the patient and the appropriate treatment protocol.
The compounds may be administered concurrently (e.g.,
simultaneously, essentially simultaneously or within the same
treatment protocol) or sequentially, depending upon the nature of
the disease, disorder, or condition, the condition of the patient,
and the actual choice of compounds used. The determination of the
order of administration, and the number of repetitions of
administration of each therapeutic agent during a treatment
protocol, is well within the knowledge of the physician after
evaluation of the disease being treated and the condition of the
patient.
[0901] Therapeutically-effective dosages can vary when the drugs
are used in treatment combinations. Methods for experimentally
determining therapeutically-effective dosages of drugs and other
agents for use in combination treatment regimens are described in
the literature. For example, the use of metronomic dosing, i.e.,
providing more frequent, lower doses in order to minimize toxic
side effects, has been described extensively in the literature
Combination treatment further includes periodic treatments that
start and stop at various times to assist with the clinical
management of the patient.
[0902] For combination therapies described herein, dosages of the
co-administered compounds will of course vary depending on the type
of co-drug employed, on the specific drug employed, on the disease
or condition being treated and so forth. In addition, when
co-administered with one or more biologically active agents, the
compound provided herein may be administered either simultaneously
with the biologically active agent(s), or sequentially. If
administered sequentially, the attending physician will decide on
the appropriate sequence of administering protein in combination
with the biologically active agent(s).
[0903] In any case, the multiple therapeutic agents (one of which
is a compound of Formulas (I), (IA), (II), (IIA), (III), (IIIA),
(IV), (IVA), (V), (VA), (VI), (VIA), (VII), (VIIA), (VIII),
(VIIIA), (IX), (IXA), (X), (XI), (XIA), (XII), or (XIIA) described
herein) may be administered in any order or even simultaneously. If
simultaneously, the multiple therapeutic agents may be provided in
a single, unified form, or in multiple forms (by way of example
only, either as a single pill or as two separate pills). One of the
therapeutic agents may be given in multiple doses, or both may be
given as multiple doses. If not simultaneous, the timing between
the multiple doses may vary from more than zero weeks to less than
four weeks. In addition, the combination methods, compositions and
formulations are not to be limited to the use of only two agents;
the use of multiple therapeutic combinations are also
envisioned.
[0904] It is understood that the dosage regimen to treat, prevent,
or ameliorate the condition(s) for which relief is sought, can be
modified in accordance with a variety of factors. These factors
include the disorder or condition from which the subject suffers,
as well as the age, weight, sex, diet, and medical condition of the
subject. Thus, the dosage regimen actually employed can vary widely
and therefore can deviate from the dosage regimens set forth
herein.
[0905] The pharmaceutical agents which make up the combination
therapy disclosed herein may be a combined dosage form or in
separate dosage forms intended for substantially simultaneous
administration. The pharmaceutical agents that make up the
combination therapy may also be administered sequentially, with
either therapeutic compound being administered by a regimen calling
for two-step administration. The two-step administration regimen
may call for sequential administration of the active agents or
spaced-apart administration of the separate active agents. The time
period between the multiple administration steps may range from, a
few minutes to several hours, depending upon the properties of each
pharmaceutical agent, such as potency, solubility, bioavailability,
plasma half-life and kinetic profile of the pharmaceutical agent.
Circadian variation of the target molecule concentration may also
determine the optimal dose interval.
[0906] In addition, the compounds described herein also may be used
in combination with procedures that may provide additional or
synergistic benefit to the patient. By way of example only,
patients are expected to find therapeutic and/or prophylactic
benefit in the methods described herein, wherein pharmaceutical
composition of a compound disclosed herein and/or combinations with
other therapeutics are combined with genetic testing to determine
whether that individual is a carrier of a mutant gene that is known
to be correlated with certain diseases or conditions.
[0907] The compounds described herein and combination therapies can
be administered before, during or after the occurrence of a disease
or condition, and the timing of administering the composition
containing a compound can vary. Thus, for example, the compounds
can be used as a prophylactic and can be administered continuously
to subjects with a propensity to develop conditions or diseases in
order to prevent the occurrence of the disease or condition. The
compounds and compositions can be administered to a subject during
or as soon as possible after the onset of the symptoms. The
administration of the compounds can be initiated within the first
48 hours of the onset of the symptoms, preferably within the first
48 hours of the onset of the symptoms, more preferably within the
first 6 hours of the onset of the symptoms, and most preferably
within 3 hours of the onset of the symptoms. The initial
administration can be via any route practical, such as, for
example, an intravenous injection, a bolus injection, infusion over
about 5 minutes to about 5 hours, a pill, a capsule, transdermal
patch, buccal delivery, and the like, or combination thereof. A
compound is preferably administered as soon as is practicable after
the onset of a disease or condition is detected or suspected, and
for a length of time necessary for the treatment of the disease,
such as, for example, from 1 day to about 3 months. The length of
treatment can vary for each subject, and the length can be
determined using the known criteria. For example, the compound or a
formulation containing the compound can be administered for at
least 2 weeks, preferably about 1 month to about 5 years.
Inhibitors of SOCE
[0908] In one aspect, compounds of Formulas (I), (IA), (II), (IIA),
(III), (IIIA), (IV), (IVA), (V), (VA), (VI), (VIA), (VII), (VIIA),
(VIII), (VIIIA), (IX), (IXA), (X), (XI), (XIA), (XII), or (XIIA)
are administered or used in conjunction with other inhibitors of
SOCE. In one aspect, the inhibitors of SOCE are non-selective
inhibitors.
[0909] A variety of inhibitors of SOCE have been described.
Inhibitors of SOCE include:
a) Cations, which include lanthanide cations, such as for example,
Gd.sup.3+, La.sup.3+; b) P-450 inhibitors, which include econazole,
miconazole, clotrimazole, ketoconazole; c) Cyclooxygenase
inhibitors, which include niflumic acid, flufenamic acid, tenidap;
d) Lipoxygenase inhibitors, which include nordihydroguaiaretic
acid, eicosatetraynoic acid; e) Compounds that are channel
blockers, which include SK&F 96365, SC38249, LU52396,
L-651,582, tetrandrine, 2-APB; f) Compounds that inhibit SOCE not
by an action on the SOC channels themselves, which include U73122
(phospholipase C inhibitor), wortmannin (phosphatidylinositol
kinase inhibitor).
[0910] Some of these inhibitors of SOCE have non-specific actions
and/or multiple modes of action that contribute to the inhibition
of SOCE, which include blocking the pore of the SOC channel
(Channel blockers), inhibition of mitochondrial ATP synthesis that
appears to support SOCE (Gamberucci et al., J Biol. Chem., 269,
23597-23602, 1994; Marriott et al., Am. J. Physiol., 269,
C766-C774, 1995), disturbances of cytoplasmic pH (Muallem et al.,
Am. J. Physiol., 257, G917-G924, 1989), as well as inhibiting the
activation of SOC channels.

[0911] In one embodiment, compounds described herein are
administered as single agents in immunosuppressive therapy to
reduce, inhibit, or prevent activity of the immune system.
Immunosuppressive therapy is clinically used to: prevent the
rejection of transplanted organs and tissues (e.g. bone marrow,
heart, kidney, liver); treatment of autoimmune diseases or diseases
that are most likely of autoimmune origin (e.g. rheumatoid
arthritis, myasthenia gravis, systemic lupus erythematosus, Crohn's
disease, and ulcerative colitis); and treatment of some other
non-autoimmune inflammatory diseases (e.g. long term allergic

Assays
[0930] Several techniques may be used to evaluate store operated
calcium entry and calcium signaling in cells. Such techniques
include, but are not limited to, patch clamp electrophysiology
(measurement of calcium ions or other ions across cell membranes,
such as plasma membranes), capacitance measurements (allows
exocytosis to be followed at the level of single cells), calcium
imaging using fluorescent dyes allows patterns of calcium movement
within the cytoplasm to be tracked, fluorescence resonance energy
transfer (FRET) enables protein-protein interactions to be
evaluated, and molecular biology methods allow for the manipulation
of the levels of expression of proteins of interest.
[0931] A wide variety of assay methods may be used to examine the
modulation of intracellular calcium by compounds of Formulas (I),
(IA), (II), (IIA), (III), (IIIA), (IV), (IVA), (V), (VA), (VI),
(VIA), (VII), (VIIA), (VIII), (VIIIA), (IX), (IXA), (X), (XI),
(XIA), (XII), or (XIIA). Such assays include in vitro cell based
assays as well as in vivo animal models. Any assays that detect,
monitor or measure an effect on intracellular calcium, including
calcium entry-mediated events can be used. Such assays include, but
are not limited to, assays monitoring, measuring and/or detecting
intracellular calcium levels, modulation of calcium levels, and
movement of calcium into, out of or within cells and intracellular
organelles. Assays can also include monitoring, measuring and/or
detecting calcium entry-mediated events and molecules involved in
calcium entry-mediated events such as, but not limited to, signal
transduction molecules, transcription factors, secreted molecules
and other molecules that are affected by changes in calcium
homeostasis. Assays include, but are not limited to, those
described herein and those described in US patent publication no.
2007/0031814 and WO 07/081804, herein incorporated by
reference.
Cells and Cell Models
[0932] For in vitro testing of the modulation of intracellular
calcium by compounds of Formulas (I), (IA), (II), (IIA), (III),
(IIIA), (IV), (IVA), (V), (VA), (VI), (VIA), (VII), (VIIA), (VIII),
(VIIIA), (IX), (IXA), (X), (XI), (XIA), (XII), or (XIIA), a wide
variety of cell types for such assays are available. In a
particular embodiment, the cell is one in which store-operated
calcium entry occurs or that can be manipulated such that
store-operated calcium entry occurs in the cell. In particular
embodiments, the cell contains one or more proteins involved in
modulating intracellular calcium (and, in particular, is involved
in, participates in and/or provides for store-operated calcium
entry, movement of calcium into, out of or within an intracellular
organelle or calcium store, modulation of calcium levels in an
intracellular organelle or calcium store (e.g., endoplasmic
reticulum) and/or calcium buffering), such as those provided
herein. In particular embodiments, the protein(s) include STIM
proteins (including STIM1, STIM2, DSTIM and CSTIM protein) and/or
Orai proteins (Orai1, Orai2, Orai3). The cell may endogenously
express the protein(s) or recombinantly express the protein(s).
[0933] Cells for use in the methods may be of any species. In one
embodiment, the cells can be eukaryotic cells. In one embodiment,
the cells can be yeast, insect (e.g., Drosophila or Anopheles), or
mammalian cells. Mammalian cells include, but are not limited to,
rodent (e.g., mouse, rat and hamster), primate, monkey, dog,
bovine, rabbit and human cells. A variety of cell types can be used
in the methods, including, for example, neuronal, nervous system,
brain, immune system cells, e.g., T lymphocytes and B cells,
primary cells, blood and hematopoietic cells, stromal cells,
myeloid cells, lymphoid cells, and a variety of tumor and cancer
cells. Particular cells include Drosophila Schneider 2 or S2 cells,
human embryonic kidney (HEK293) cells, rat basophilic leukemia
(RBL-2H3) cells, Jurkat cells, epithelial cells, rhabdomyosarcoma
cells, rhabdoid cells, retinoblastoma cells, neuroepithelioma
cells, neuroblastoma cells, osteosarcoma cells, fibroblasts, bone
marrow stroma cells, erythroleukemia cells and lymphoblast cells.
Other cell lines include HEK 293 and 293T, CHO (including CHO-K1),
LTK-, N2A, H6, and HGB. Many such cells and cell lines are
available through cell depositories such as, for example, the
American Type Culture Collection (ATCC, Manassas, Va.). Primary
cells can be obtained by isolation from tissue sources.
[0934] Cells from a known cell line can be used, such as
neuroblastoma SH-SY5Y cells, pheochromocytoma PC12 cells,
neuroblastoma SK--N-BE(2)C or SK-N-SH cells, human SK-N-MC
neuroepithelioma cells, SMS-KCNR cells, human LAN-5 neuroblastoma
cells, human GI-CA-N neuroblastoma cells, human GOTO neuroblastoma
cells, mouse Neuro 2a (N2A) neuroblastoma cells and/or human IMR 32
neuroblastoma cells, chronic myeloid leukemia cells (e.g., human
K562 cells), promyelocytic leukemia cells (e.g., HL60 cells) and
histiocytic lymphoma cells (e.g., U937 cells), Burkitt's lymphoma
cells (e.g., CA46 cells), B-cells (e.g., NALM6), acute
lymphoblastic leukemia cells (e.g., MOLT4 cells), T cells (e.g.
Jurkat cells) and early T-ALL (e.g., DU528) cells.
[0935] In one embodiment, the choice of a cell for use in an in
vitro assay to test the modulation of intracellular calcium by
compounds described herein involves several considerations,
including, for example, a particular protein that is being used in
the method and a particular aspect or activity of intracellular
calcium modulation that is being monitored or assessed in the
method.
[0936] In one embodiment, the modulation of intracellular calcium
by a compound described herein, or (XIIIA) is examined by
monitoring or assessing the effect on store-operated calcium entry.
Cells typically used in such methods exhibit store-operated calcium
entry either naturally or through manipulation of the cells. Cells
that endogenously exhibit store-operated calcium entry include some
excitable cells and most non-excitable cells and can be identified
using methods described herein and/or recognized in the field.
[0937] In one embodiment, it may be desirable to utilize a cell
that contains components of signaling and messenger systems that
can effect release of calcium from intracellular stores. For
example, cells containing components of receptor-mediated
phospholipase C (PLC) activation systems can be used for
physiological activation (via generation of IP.sub.3) of store
depletion to facilitate monitoring of store-operated calcium entry.
Receptor-mediated PLC activation occurs through distinct coupling
mechanisms: PLC-activation by G protein-coupled receptors (GPCRs)
and PLC-.gamma. activation by tyrosine kinase receptors and
nonreceptor tyrosine kinases. Thus, cells containing a
receptor-mediated PLC-activation system can be monitored or
assessed for store-operated calcium entry upon agonist activation
of one or more receptors known to participate in the system. (see
e.g. Bouron (2000) FEBS Lett 470:269-272; Millar et al. (1995) J.
Exp. Biol. 198:1843-1850; Yagodin et al. (1998) Cell Calcium
23:219-228; Yagodin et al. (1999) Cell Calcium 25:429-438; and
Patterson et al. (2002) Cell 111:1-20).
[0938] An assessment of intracellular calcium after treatment with
a compound described herein can be made under a variety of
conditions. Conditions can be selected to evaluate the effect of
test agent on a specific aspect of intracellular calcium. For
example, reagents and conditions are used, for specifically
evaluating store-operated calcium entry, resting cytosolic calcium
levels, calcium buffering, and calcium levels of and calcium uptake
by or release from intracellular organelles.
[0939] Resting cytosolic calcium levels, intracellular organelle
calcium levels and cation movement may be assessed using any of the
methods described herein or recognized in the field. Such methods
of assessing modulation in intracellular calcium include, but are
not limited to, calcium-sensitive indicator-based measurements,
such as fluo-3, mag-fura 2 and ER-targeted aequorin, labeled
calcium (such as .sup.45Ca.sup.2+)-based measurements, and
electrophysiological measurements. Particular aspects of ion flux
that may be assessed include, but are not limited to, a reduction
(including elimination) in the amount of ion flux, altered
biophysical properties of the ion current, and altered
sensitivities of the flux to activators or inhibitors of calcium
flux processes, such as, for example, store-operated calcium entry.
Reagents and conditions for use in specifically evaluating
receptor-mediated calcium movement and second messenger-operated
calcium movement are also available.
Evaluation of Store-Operated Calcium Entry
[0940] In one aspect, compounds described herein are added to cells
under conditions that permit store-operated calcium entry to occur
in order to assess the effects of Formulas (I), (IA), (II), (IIA),
(III), (IIIA), (IV), (IVA), (V), (VA), (VI), (VIA), (VII), (VIIA),
(VIII), (VIIIA), (IX), (IXA), (X), (XI), (XIA), (XII), or (XIIA) on
store-operated calcium entry. Such conditions are described herein
and are recognized in the field.
[0941] For example, in one method cells may be treated to reduce
the calcium levels of intracellular calcium stores and then
analyzed for evidence of ion (e.g., calcium) influx in response
thereto in the presence of a compound described herein. Techniques
for reducing calcium levels of intracellular stores and for
analyzing cells for evidence of ion (e.g., calcium) influx are
recognized in the field and described herein.
[0942] In other methods, electrophysiological analysis of currents
across a cell-detached plasma membrane patch or an outside-out
membrane vesicle may be used to detect or monitor store-operated
channel currents (e.g., I.sub.SOC, I.sub.CRAC) in the presence of a
compound described herein.
Evaluation of Calcium Entry-Mediated Events
[0943] A number of molecules involved in calcium-regulated pathways
are known. Evaluation of molecules involved in calcium-entry
mediated events can be used to monitor intracellular calcium, and
can be used, for example in screening assays described herein to
monitor the effects of the compounds presented herein. Examples of
assays include but are not limited to assays which detect, or
determine the presence, levels, alteration of levels, production,
modification (such as phosphorylation and dephosphorylation),
translocation, degradation and activity of molecules involved in
calcium-entry mediated events (see for example, Trevillyan et al.
(2001) J. Biol. Chem. 276:48118-26). The assays described herein
can be used with cells that have been treated with or contacted
with a compound presented herein, or that express an altered amount
of a test molecule (such as a protein involved in calcium
regulation, including a STIM protein, Orai protein), or with
control cells. The assays can also be conducted in cells that have
been stimulated with a physiological or non-physiological
activator, or in unstimulated cells. The following are
representative assays for molecules involved in calcium-entry
mediated events and are meant to be exemplary only. Other assays
for these molecules and assays for other molecules involved in
calcium-entry mediated events can also be employed in any of the
screening and/or modulation methods described herein.
.beta.-Hexosaminidase Release
[0944] In mast cells, Ca.sup.2+ influx results in degranulation and
release of inflammatory mediators such as heparin, histamine and
enzymes such as .beta.-hexosaminidase. Detecting and/or measuring
release of such molecules can thus be used to monitor intracellular
calcium. For example, media from mast cells can be collected. A
suitable substrate for .beta.-hexosaminidase (e.g.
p-nitrophenyl-acetyl-glucosamide) can then be added and the
absorbance of the resulting mixture assessed to measure the
relative amount of .beta.-hexosaminidase activity in the samples
(Funaba et al. (2003) Cell Biol. International 27:879-85).
Calcium/Calmodulin-Dependent CaN Phosphatase Activity
[0945] The phosphatase calcineurin (CaN) dephosphorylates various
proteins, affecting their activity and localization. CaN activity
can be assessed by incubating purified CaN and a CaN substrate, for
example a radiolabeled peptide corresponding to a sequence in the
RII subunit of cAMP-dependent kinase, either with or without a
compound of Formulas (I), (IA), (II), (IIA), (III), (IIIA), (IV),
(IVA), (V), (VA), (VI), (VIA), (VII), (VIIA), (VIII), (VIIIA),
(IX), (IXA), (X), (XI), (XIA), (XII), or (XIIA) (see, Trevillyan et
al. (2001) J. Biol. Chem 276:48118-26). The level of radiolabeled
peptide and/or the amount of free inorganic phosphate released can
be measured to assess CaN dephosphorylation activity.
NFAT Transcriptional Activity
[0946] The NFAT (nuclear factor of activated T cells) transcription
factor regulates a number of genes in response to intracellular
calcium levels. For example, NFAT proteins regulate the
transcription of cytokine genes involved in the immune response.
Promoters from NFAT-regulated genes, and/or regulatory regions and
elements from these genes, can be used to monitor NFAT regulated
expression and thereby monitor intracellular calcium. Reporter gene
fusions can be constructed with NFAT regulated promoters or
NFAT-regulated elements operably linked to a reporter gene such as
luciferase, 0-galactosidase, green fluorescent protein (GFP) or any
other known reporter in the art (see for example, Published U.S.
Application no. 2002-0034728). The amount of reporter protein or
activity is a measure of NFAT activity.
NFAT Phosphorylation
[0947] NFAT activation is regulated primarily through its
phosphorylation, which in turn regulates its subcellular
localization. In unstimulated cells, NFAT is a hyperphosphorylated
cytosolic protein. An elevation in intracellular Ca.sup.2+, induced
by a variety of mechanisms, increases the activity of the
Ca.sup.2+-calmodulin-dependent phosphatase, calcineurin. Activated
calcineurin dephosphorylates multiple serine residues within the
regulatory region of the NFAT molecule. NFAT is rephosphorylated in
response to decreases in Ca.sup.2+ levels or CaN inhibition.
[0948] The phosphorylation state of NFAT can be monitored for
example, by expressing a detectably tagged NFAT protein in cells,
such as a His6 tagged-NFAT. Tagged NFAT can be purified from cells
using Ni.sup.2+ chromatography and subjected to gel electrophoresis
and staining or western blotting. More highly phosphorylated forms
of NFAT can be distinguished by their slower migration. The state
of phosphorylated NFAT can be used as a measure of NFAT activation
(see, Trevillyan et al. (2001) J. Biol. Chem 276:48118-26).
NFAT Nuclear Localization
[0949] NFAT localization between the cytoplasm and nucleus is
regulated by the phosphorylation state of NFAT. Phosphorylation of
NFAT prevents nuclear localization by masking the nuclear
localization sequence. NFAT nuclear localization can be monitored,
for example, by expressing fluorescently tagged NFAT, for example,
GFP-NFAT, in cells. Confocal microscopy can be used to monitor
nuclear localization of the tagged NFAT (see, Trevillyan et al.
(2001) J. Biol. Chem 276:48118-26).
Cytokine Secretion
[0950] Cytokine secretion, such as IL-2 secretion, can be monitored
using protein detection assays. For example, supernatant can be
collected from immune cells. An ELISA assay or other suitable
format with IL-2 antibodies can be used to detect and/or measure
the amount of IL-2 secreted as compared to control cells. Secretion
of other cytokines, for example, TNF-.alpha., can also be detected
in similar assays.
Cytokine Expression
[0951] Expression of cytokines, such as, but not limited to IL-2,
can be assessed either directly or indirectly in cells. For
example, in indirect methods, an IL-2 promoter can be operably
linked to a reporter gene such as luciferase or 3-galactosidase,
and the reporter construct introduced into cells. Reporter gene
expression can be monitored and compared to gene expression in
control cells (see, Trevillyan et al. (2001) J. Biol. Chem
276:48118-26). Alternatively, expression of endogenous or
recombinant IL-2 mRNA or protein can be assessed.
T Cell Proliferation
[0952] Cytokines such as IL-2 are necessary for T-cell
proliferation in response to mitogen or alloantigen stimulation,
and thus T-cell proliferation is altered by changes in cytokine
expression or secretion. T cells can be induced, such as with
concanavalin A or alloreactive lymphocytes and T cell proliferation
measured, for example, by subjecting cells to a pulse of
.sup.3H-thymidine and measuring .sup.3H-thymidine incorporation
(see, Trevillyan et al. (2001) J. Biol. Chem 276:48118-26).
[0953] In some embodiments, the modulation (e.g. inhibition or
reduction) of SOCE by compounds presented herein are determined by
evaluation of any of the following criteria:
a. there is direct inhibition of increased [Ca.sup.2]i as measured
by a calcium indicator; b. there is a direct inhibition of
I.sub.SOC or I.sub.CRAC as measured by patch clamp; c. there is
inhibition of downstream signaling functions such as calcineurin
activity, NFAT subcellular localization, NFAT phosphorylation,
and/or cytokine, e.g., IL-2, production; or d. there are
modifications in activation-induced cell proliferation,
differentiation and/or apoptotic signaling pathways.
Animal Models
[0954] Animal models that can be used in embodiments of the methods
further include animals, such as, but not limited to non-human
animals, which have, in at least some of their cells, an alteration
or defect in, or aberrant functioning of, a cellular process which
relies on or is regulated by intracellular calcium. Cellular
processes that rely on or are regulated by intracellular calcium
include, for example, cellular activation, gene expression,
cellular trafficking, and apoptosis. Diseases/disorders that
involve defects that may be at least partially compensated for by
modulation of intracellular calcium include, but are not limited
to: autoimmune disorders, including rheumatoid arthritis,
inflammatory bowel disease, Sjogren's syndrome (cytokines
associated with lymphocyte invasion of salivary epithelial cells
can reduce calcium mobilization in parotid cells; also, T-cell
activation, including activation of transcription factors, cytokine
gene expression and cell proliferation, depends on sustained
elevation of intracellular calcium level provided by store-operated
calcium influx), asthma (store-operated calcium entry may play an
important role in mediating bronchial chonstriction and bronchial
smooth muscle cell proliferation), glomerulonephritis and
glomerular inflammation (changes in intracellular calcium, such as
by store-operated calcium entry, signal monocyte adhesion in a
co-culture model of glomerular inflammation).
[0955] Types of animal models include, but are not limited to,
non-human animals, such as non-human invertebrates and vertebrates
and non-human mammals, rodents (e.g., mice, rat and hamster), cows,
chickens, pigs, goats, dogs, sheep, insects, Drosophila, nematodes,
worms, C. elegans, monkeys, gorillas, and other primates.
[0956] Animal models include transgenic and non-transgenic animals.
One example of such an animal model that can be used in particular
embodiments of the methods is a rodent model of airway
hyperresponsiveness (AHR), a characteristic of asthma. This model
can be generated, for example, by sensitization through
immunization with ovalbumin followed by exposure to aerosolized
ovalbumin and challenge by cholinergic stimulation (e.g., via
administration of methacholine or acetylcholine) (see, e.g., Xu et
al. (2002) J. Appl. Physiol. 93:1833-1840; Humbles et al (2002)
Proc. Natl. Acad. Sci. 99:1479-1484). Airway hyperresponsiveness
(which can be evaluated using methods, such as for e.g., using
barometric plethysmography to record respiratory pressure curves
and through measurement of pulmonary parameters such as pulmonary
conductance and pulmonary compliance) can be assessed and compared
in animals treated and not treated with a compound presented
herein. A further example of an animal model that can be used in
particular embodiments of the methods is a rodent model of
mesangial proliferative glomerulonephritis, which can be generated,
for example, by administration of anti-Thy1.1 antibody (see, e.g.,
Jefferson and Johnson (1999) J. Nephrol. 12:297-307). Any number of
parameters indicative of glomerulonephritis or renal dysfunction
(e.g., mesangial cell proliferation, blood pressure, urinary
protein excretion, creatinine clearance, glomerulosclerosis index
and other parameters) can be evaluated and compared in animals
treated with and not treated with test agent. The non-obese
diabetic (NOD) mouse, an inbred mouse strain that spontaneously
develops autoimmune diabetes that shares many immunogenetic
features with Type 1 diabetes mellitus, is another example of an
animal model that can be used in a particular embodiment of the
methods. These mice also manifest many characteristics of
autoimmune exocrinopathy (such as Sjorgen's syndrome) including
declining exocrine tissue secretory function (see, e.g.,
Humphreys-Beher and Peck (1999) Arch. Oral Biol. 44 Suppl 1:S21-25
and Brayer et al. (2000) J Rheumatol. 27:1896-1904).
Characteristics relevant to Sjorgen's syndrome (e.g., lymphocytic
infiltrates in exocrine glands (e.g., salivary and lacrimal
glands), presence of dendritic cells and macrophages in
submandibular glands, integrity of the lacrimal gland by
measurement of basal and stimulated tear secretion, saliva flow
rates and amylase activity) can be evaluated and compared in
animals treated with and not treated with a compound described
herein. An animal (e.g., rodent) model of autoimmune disease can
also be used in particular embodiments of the methods. Such animals
include rat models available through the National Institutes of
Health (NIH) Autoimmune Rat Model Repository and Development Center
(Bethesda, Md.; accessible at
www.ors.od.nih.gov/dirs/vrp/ratcenter). One rat model of rheumatoid
arthritis (RA) and related chronic/inflammatory autoimmune diseases
is the collagen-induced arthritis (CIA) model (see, e.g., Griffiths
and Remmers (2001) Immunol. Rev. 184:172-183). Characteristic
phenotypes of autoimmune disease (e.g. altered levels of immune
reactivity to self-antigens, chronic inflammation of
autoantigen-expressing target organs, and activation and
participation of invading mononuclear cells and tissue fibroblasts
in organ damage) can be evaluated and compared in animals treated
with and not treated with a compound presented herein. An animal
(e.g., rodent) model of neuropathic or inflammatory pain can also
be used in a particular embodiment of the methods. For example, one
rat model of neuropathic pain involves development of tactile
allodynia (exaggerated response to otherwise innocuous stimuli)
after ligation of lumbar spinal nerves (see, e.g., Chaplan et al.
(1994) J. Neurosci. Methods 53:55-63 and Luo et al. (2001) J.
Neurosci. 21:1868-1875). Tactile allodynia, one characteristic
feature of neuropathic pain, can be evaluated (e.g., by evaluating
paw withdrawal threshold in response to application of pressure)
and compared in animals treated and not treated with a compound
described herein.

In Vitro Screening for Agents that Modulate Intracellular Calcium
Levels
[1087] Fluorescence-based assays are used for screening the
compounds described herein, such as compounds of Formulas (I),
(IA), (II), (IIA), (III), (IIIA), (IV), (IVA), (V), (VA), (VI),
(VIA), (VII), (VIIA), (VIII), (VIIIA), (IX), (IXA), (X), (XI),
(XIA), (XII), or (XIIA) which modulate intracellular calcium.
A. Fluorescence-Based Assay of Store-Operated Calcium Entry in
Orai1/STIM1 Stable Cells.
Cells:
[1088] Cells stably expressing recombinant human STIM1 and Orai1
are generated by transfecting a human Orai1 expression plasmid
(pcDNA3.1-Orai1-cmyc) into HEK-293 cells stably overexpressing
human STIM1 (Roos et al. 2005 JCB 169(3): 435-445). Colonies of
cells stably expressing both STIM1 and Orai1 proteins are selected
and then subcloned by limiting dilution. Cells were cultured at
37.degree. C./6% CO.sub.2 in complete medium with 10% FBS and
appropriate selection markers.
Assay:
[1089] The day prior to performing the assay Orai1/STIM1 stable
cells are plated in 50 .mu.L of complete medium at 90-95%
confluence in a 384 well plate. Cells are grown at 37.degree. C./6%
CO.sub.2 overnight. On the day of the assay, 1.5 .mu.M fluo-4-AM
(Invitrogen) in complete medium is added to the cells, which are
then incubated for 1 hour at RT. Cells are washed once in
Ca.sup.2+-free HBSS (Hank's buffered saline solution) and 35 .mu.l
of Ca.sup.2+-free HBSS is added to each well. Test compounds are
added to wells in a 10 .mu.L Ca.sup.2+-free HBSS solution, prepared
at 4.5.times. the desired final concentration, and incubated for 30
minutes at RT. The initial baseline fluorescence signal is then
measured with a FLIPR.sup.384 (Molecular Devices) plate reader.
Calcium entry is initiated by adding 5 .mu.l of 10.times.CaCl.sub.2
(10 mM) in HBSS, and changes in cellular fluorescence are measured
with the FLIPR.sup.384 plate reader. In each well, the magnitude of
the fluorescence signal as a result of calcium entry into the cell
is determined by calculating the difference between the peak
fluorescence signal measured after calcium addition and the initial
baseline fluorescence signal (designated Peak-Basal). IC.sub.50
values are typically calculated as the concentration that inhibited
50% of the Peak-Basal signal.
B. Fluorescence-Based Assay of Store-Operated Calcium Entry in
RBL-2H3 Cells.
Cells:
[1090] RBL-2H3 cells are obtained from ATCC and maintained in
complete medium with 10% FBS at 37.degree. C./6% CO.sub.2.
Assay:
[1091] The day prior to performing the assay, RBL-2H3 cells are
plated in 50 .mu.L of complete medium in a 384 well plate. Cells
are grown at 37.degree. C./6% CO.sub.2 overnight and grow to 50-60%
confluence by the next day. On the assay day, 1.5 .mu.M Fluo-4-AM
dye (Invitrogen) in complete medium is added and incubated for 1
hour at RT. Cells are washed twice in Ca.sup.2+-free HBSS buffer
and 35 .mu.L Ca.sup.2+-free HBSS buffer is added to each well. 10
.mu.L of a test compound prepared in a Ca.sup.2+-free HBSS solution
at 4.5.times. of the desired concentration is added to a well and
incubated for 5 minutes at RT. 10 .mu.L of thapsigargin prepared in
a Ca.sup.2+-free HBSS solution at 5.5.times. of the desired
concentration (5.5 uM) is added to each well and incubated for an
additional 25 minutes. The initial baseline fluorescence signal is
measured with a FLIPR.sup.384 (Molecular Devices) plate reader. 5
.mu.L of 12.times. calcium in HBSS (12 mM) is added and changes in
cellular fluorescence are measured with the FLIPR.sup.384 plate
reader. In each well, the change in the fluorescent signal as a
function of time due to calcium entry into the cell is determined
by calculating the difference between the fluorescent signal
measured 7 seconds after calcium addition and the initial baseline
fluorescence signal at time zero (t=0). This parameter is
designated Upslope. The IC.sub.50 value is calculated as the
concentration at which 50% of the Upslope is inhibited.
C. Fluorescence-Based Assay of Store-Operated Calcium Entry in
Jurkat Cells.
Cells:
[1092] Jurkat E6-1 cells are obtained from ATCC and maintained in
complete medium with 10% FBS at 37.degree. C./6% CO.sub.2.
Assay:
[1093] The day prior to performing the assay, Jurkat E6-1 cells are
seeded at a density of 2 million cells/mL in complete medium in a
T-175 flask. Cells are grown at 37.degree. C./6% CO.sub.2
overnight. On the following day, 1.5 .mu.M Fluo-4-AM dye
(Invitrogen) in complete medium is added and incubated for 1 hour
at RT. Cells are harvested, washed twice in Ca.sup.2+-free HBSS
buffer and plated in 35 .mu.L Ca.sup.2+-free HBSS buffer in a 384
well plate. 10 .mu.L of a test compound prepared in a
Ca.sup.2+-free HBSS solution at 4.5.times. of the desired
concentration is added to a well and incubated for 5 minutes at RT.
10 .mu.L of thapsigargin prepared in a Ca.sup.2+-free HBSS solution
at 5.5.times. of the desired concentration (5.5 uM) is added to
each well and incubated for an additional 25 minutes. The initial
baseline fluorescence signal is measured with a FLIPR.sup.384
(Molecular Devices) plate reader. 5 .mu.L of 12.times. calcium in
HBSS (12 mM) is added and changes in cellular fluorescence are
measured with the FLIPR.sup.384 plate reader. In each well, the
change in the fluorescent signal as a function of time due to
calcium entry into the cell is determined by calculating the
difference between the fluorescent signal measured 7 seconds after
calcium addition and the initial baseline fluorescence signal at
time zero (t=0). This parameter is designated Upslope. The
IC.sub.50 value is calculated as the concentration at which 50% of
the Upslope is inhibited.

In Vitro I.sub.CRAC Patch Clamp Assay
Objective
[1094] The objective of this assay is to examine the in vitro
effects of test compounds on cloned CRAC channels (Orai1 and STIM1
genes stably expressed in HEK293 cells), responsible for
I.sub.CRAC, the calcium release activated calcium channel
current.
Test and Control Articles
[1095] Formulation: Test article stock solutions are prepared in
dimethyl sulfoxide (DMSO) and stored frozen. Test article
concentrations are prepared fresh daily by diluting stock solutions
into an appropriate external recording buffer. If necessary, test
article formulations are sonicated (Model 2510, Branson
Ultrasonics, Danbury, Conn.), at ambient room temperature to
facilitate dissolution. In certain instances, the test solutions
contain up to 0.1% DMSO and the presence of 0.1% DMSO does not
affect channel current.
Test Article Concentrations and Quantity
[1096] Typically, the effects of three (3) concentrations of each
test article are evaluated (0.1, 1, and 10 .mu.M). Test articles
are weighed and prepared as 30 mM or 10 mM stock solutions in DMSO.
The DMSO stock is diluted in external recording buffer to prepare a
10 .mu.M test solution (final DMSO 0.03% or 0.1%). The 10 .mu.M
test solution is diluted in external recording buffer to prepare 1
.mu.M and 0.1 .mu.M test solutions. Test solutions contain up to
0.1% DMSO at the highest concentration which are diluted in test
solutions at lower concentrations.
Positive Control Article
[1097] Stock solutions of the positive control article are prepared
in batches, aliquoted for individual use, stored frozen and used
within six months. The positive control concentration is prepared
fresh daily by diluting stock solutions into external recording
buffer. The final DMSO concentration in the test positive control
article is up to 0.1% of the solution.
Negative Control Article
[1098] The negative control article is 0.1% DMSO in external
recording buffer.
Cloned Ion Channel Test Systems
[1099] Cells are maintained in tissue culture incubators per
CalciMedica standard protocols. Stocks are maintained in cryogenic
storage. Cells used for electrophysiology are plated in plastic
tissue culture dishes.
HEK293 Cells
[1100] HEK293 cells are stably transfected with the appropriate ion
channel cDNAs (Orai1/STIM1). Cells are cultured in DMEM (Gibco
11960) supplemented with 10% fetal bovine serum (Gibco 10082), 100
U/mL penicillin G sodium, 1 mM Na pyruvate (Gibco 11360), 100
.mu.g/mL streptomycin sulfate (Gibco 10378), 0.5 mg/ml geneticin
(Gibco 10131-035) and 50 .mu.g/ml zeocin (Invitrogen 45-0430).
Cells should be maintained at .ltoreq.80% confluence. The day
before testing, cells in culture dishes are washed once with
calcium/magnesium-free D-PBS, treated with trypsin/EDTA and
re-suspended in the culture media and counted. Cells are then
diluted in culture medium with 1% fetal bovine serum and plated at
low density (5-10K) onto poly-D-lysine coated glass coverslips in
24-well tissue culture dishes and placed in a tissue culture
incubator set at 37.degree. C. in a humidified 95% air, 6% CO.sub.2
atmosphere.
Test Methods
[1101] Recording Chamber and Perfusion of Test Articles
[1102] Glass coverslips containing cells are transferred to a
recording chamber (Warner Instruments) with continuous perfusion of
external recording buffer. During recordings of I.sub.CRAC, all
treatments are delivered by gravity-fed bath perfusion from
disposable syringe reservoirs via disposable polyethylene tubing
feeding into a Teflon manifold. The flow rate is set between
1.2-1.5 ml/min assuring complete solution exchange in .about.1 min.
All experiments are performed at ambient temperature.
[1103] Test Article Treatment Groups
[1104] For experiments where the test article is applied for 10
minutes the treatment paradigm is summarized in Table 2. Control
recording buffer is perfused for five (5) minutes while I.sub.CRAC
develops and a stable baseline is established; each cell is used as
its own control. Each test article is applied to naive cells
(n.gtoreq.2, where n=the number cells/concentration; at 1
concentration/cell) for a duration of ten (10) minutes (Table 2).
The test article is washed off for ten (10) minutes to look for
reversibility of the effect. External recording saline with no
calcium is perfused for two (2) minutes to determine the background
current in the absence of I.sub.CRAC. Control saline containing
calcium is reapplied for three (3) minutes.
[1105] For experiments where the test article is applied for 30
minutes prior to recording of I.sub.CRAC, the treatment paradigm is
summarized in Table 3. Prior to the start of each experiment, cells
are incubated with compound for 30 minutes at room temperature, and
compound remains present throughout I.sub.CRAC recordings. Control
cells are exposed to vehicle only. After break-in and establishment
of the whole-cell patch clamp configuration, recording
buffer.+-.compound is perfused for ten (10) minutes. At the end of
the 10 min period the amplitude of I.sub.CRAC is measured. The
effects of compounds are determined by comparing the I.sub.CRAC
signal in cells pretreated with compound to the signal in cells
pretreated with vehicle.

Control Treatment Groups
[1106] As a negative control, 0.1% DMSO is applied to naive cells
(n.gtoreq.2, where n=the number cells. This is used to monitor the
magnitude of rundown of I.sub.CRAC. As a positive control, 1 .mu.M
of 4-(4-bromophenyl)-2-(3-fluorobenzamido)thiophene-3-carboxylic
acid is routinely applied to naive cells (n.gtoreq.2, where n=the
number cells).
[1107] Whole Cell Patch Clamp Procedures
[1108] Standard whole cell patch clamp procedures are used. The
compositions of the extracellular and intracellular solutions are
shown in Tables 4 and 5. Cells are visualized on an inverted
microscope (Olympus IX71) and voltage clamped using a Multiclamp
700B amplifier and PClamp software (Axon Instruments). Briefly,
borosilicate patch pipettes filled with intracellular solution
(Appendix 1) are positioned onto the cell membrane. Once a G.OMEGA.
seal is formed, suction is applied until the patch ruptures and the
whole cell configuration is established. The quality of the
configuration will be evaluated with the "membrane test" in Clampex
to determine cell capacitance (Cm), input resistance (Rm), access
resistance (Ra), and holding current at -50 mV (Ih). Data are
stored on the CalciMedica computer network (and backed-up nightly)
for off-line analysis.

I.sub.CRAC Test Procedures
[1111] I.sub.CRAC from the Orai1/STIM1 channel complex is activated
by passive depletion of intracellular calcium stores using 20 mM
BAPTA in the intracellular solution. Voltage clamp data is acquired
using Clampex software to elicit a stimulus voltage protocol (shown
in Table 6) applied every six (6) seconds. Currents are digitized
at 10 kHz and filtered at 2 kHz. Whole cell capacitive compensation
is employed. Representative I.sub.CRAC traces are shown in FIG.
2.

monitor inwardly rectifying profile 50 ms of I.sub.CRAC Vstep to
+50 mV for 10 ms to estimate leak current
Data Analysis
[1112] Data analysis is performed using Clampfit software.
I.sub.CRAC is measured at -100 mV and the current measured after 5
min is used as the baseline control. For 10-minute application
studies, the current measured after 10 min application of the test
article is normalized to the baseline current and expressed as %
control. For 40-min application studies, the current measured at
the end of 10 minutes of I.sub.CRAC recording time is used as the
comparator. The current measured in "0 calcium" buffer is used to
subtract background leak current. Data points for each test article
concentration (n.gtoreq.2) are fitted to a sigmoid function
(SigmaPlot) to determine the IC.sub.50 and Hill slope.

Presence of NADPH-Regenerating System but without UDPGA):
[1116] A mixture of the test compound and liver microsomes (475
.mu.L total) are pre-incubated for 5 minutes at 37.degree. C. The
reactions are initiated by the addition of 25 .mu.L of the
co-factor NADPH regenerating system) and are allowed to proceed at
37.degree. C. for up to 60 minutes. The final concentrations in the
assay were: 5 .mu.M test compound, 1 mg/mL microsomal protein, 1 mM
NADP+, 5 mM glucose-6-phosphate and 1 U/mL glucose-6-phosphate
dehydrogenase in 50 mM potassium phosphate (pH 7.4) containing 3.3
mM MgCl.sub.2 and 100 .mu.M EDTA. DMSO is introduced into the
reaction mixtures with test compound stock solution; its
concentration did not exceed 0.4% (v/v). At pre-determined time
points, the reactions are terminated by removing 50 .mu.L-aliquots
and quenching them with 200 mL of ACN mixture containing 0.5 .mu.M
of the internal standard (carbamazepine) to achieve protein
precipitation. The samples are vortexed, centrifuged at 4000 rpm
(3400 rcf) for 15 minutes, and clear supernatants are analyzed by
LC/MS/MS.
[1117] Phase I and II: (Oxidative Metabolism and Conjugation in the
Presence of NADPH-Regenerating System and UDPGA):
[1118] The reaction mixtures are prepared similar to what is
described above, except 6.6 mM UDPGA, 6.25 .mu.g/mL alamethicin,
and 1.25 mM of D-Saccharic acid 1,4-lactone (final assay
concentrations) are also added together with the NADPH-regenerating
system. Midazolam and 4-methylumbelliferone are used as positive
controls for Phase I and Phase II, respectively.
[1119] Bioanalysis
[1120] Bioanalysis is conducted using a non-GLP LC/MS/MS method.
Calibration curves are not generated and the ratios of the test
compound peak area to the internal standard peak area are used to
determine the relative amounts of test compound remaining at each
time point. Stable is defined herein as less than 10%
degradation

[1137] Sensitization Solution:
[1138] 1% OVA solution is prepared in PBS (1 g of OVA is dissolved
in 100 mL PBS. The final concentration is 10 mg/mL). 6 mL 1% OVA
solution and 54 mL alum solution is added into a bottle to generate
a solution with the ratio of 1:9, this is the shaken on a
horizontal shaker at 37.degree. C. for 30 min.
[1139] Challenge Solution:
[1140] 1% OVA solution is prepared in PBS (1 g of OVA is dissolved
in 100 mL PBS. The final concentration is 10 mg/mL).
[1141] Sensitization and Challenge of Rats:
[1142] 50 Animals are randomized into 5 groups (n=10 per group).
Rats in groups 2, 3, 4, and 5 are sensitized by i.p injection (1
mL/rat) of sensitization solution on days 1, 2, and 3. Rats in
group 1 received 1 mL PBS by i.p. injection on days 1, 2, and 3. On
day 21, rats in groups 2, 3, 4, and 5 are challenged with challenge
solution for 20 min with a mass dosing system (Buxco). Rats in
group 1 are challenged with PBS.
[1143] Body Weight Measurements:
[1144] Animals are weighed on days 14, 15, 16, 17, 18, 19, 20, 21,
and 22. Each animal's body weight are recorded in Biobook real time
and the record kept in a archive database. Body weights are entered
into the Excel spreadsheet are used to determine dosing volumes for
each animal.
[1145] Drug Administration:
[1146] Test compounds and reference drug are administrated
according to the following dosage protocols: Group 1 (Sham
sensitized--Vehicle 2 group), Vehicle 2 (22.5% PEG400/1.25%
Tween-80/1.25% PVP40/75% CMC (1%)) are administered orally twice
daily on days 14, 15, 16, 17, 18, 19, 20 and 21 (2 hours before PBS
challenge on day 21); Group 2 (OVA sensitized--Vehicle 2 group),
Vehicle 2 is administered orally twice daily on days 14, 15, 16,
17, 18, 19, 20 and 21 (2 hours before OVA challenge on Day 21);
Group 3 (reference drug group), Dexamethasone (0.3 mg/kg) in
Vehicle 1 (0.5% CMC) is administered orally twice daily on days 18,
19, 20 and 21 (2 hours before OVA challenge on day 21); Group 4,
one dosage of Test Compound (57 mg/kg) in Vehicle 2 is administered
orally twice daily on days 14, 15, 16, 17, 18, 19, 20 and 21 (2
hours before OVA challenge on day 21); Group 5, one dosage of Test
Compound (57 mg/kg) in Vehicle is administered orally once daily on
days 14, 15, 16, 17, 18, 19, 20 and 21 (2 hours before OVA
challenge on day 21).
[1147] Sample Collection:
[1148] On day 22, animals are anesthetized by intraperitoneal
injection of 1% pentobarbital sodium (60 mg/kg). Blood samples are
collected into EDTA-K2 tubes from the abdominal aorta under
pentobarbital anesthesia.
[1149] Immediately after blood sampling, animals are sacrificed by
cervical dislocation. Lungs are lavaged via the tracheal cannula
with 3 ml of PBS (containing 1% FBS) the first time. Then the
course is repeated twice more with 5 mL PBS (containing 1% FBS) for
each time. The BALF is stored on ice and kept separate from the
subsequent lavages. Cell pellets from the three lavages are pooled
together and will be adjusted to the volume of 15 ml for cell
number counting. Total numbers of cells in BALF are estimated using
a haemocytometer and trypan blue exclusion assay. The BALF is then
centrifuged at 4.degree. C. at 300.times.g for 5 min and the cells
are resuspended in PBS (containing 1% FBS) for smear preparation.
Smears are made by diluting cells (to approximately 10.sup.7
cells/ml) and pipetting an aliquot (100 .mu.l) into a
cytocentrifuge sample chamber, and centrifuged at 800 rpm for 5
min. The slides are dried in air, fixed in methanol for 1 minute,
and then stained in Wright's stain solution (1 minute) followed by
Giemsa stain solution (7 minutes) in order to differentiate
eosinophils, neutrophils, macrophages, and lymphocytes. A total of
200 cells per smear are counted under light microscopy.
[1150] All the blood samples are collected in EDTA-K2 tubes. After
plasma isolation, 3 aliquots of 0.5 mL plasma and stored in
-80.degree. C.

Model
[1151] Purpose:
[1152] Determine efficacy of Test Compound administered by oral
dosing qd, in inhibiting the inflammation, pannus formation,
cartilage destruction and bone resorption of developing type II
collagen arthritis in rats.
[1153] Animals:
[1154] Female Lewis rats (Charles River), weighing 125-150 g at the
start of the study.
[1155] Rats are injected with collagen to get solid responders on
days 10 and 11. Four nonimmunized animals serve as normal
controls.
[1156] Materials:
[1157] Test Compound, Type II collagen, Freund's incomplete
adjuvant, acetic acid. Test Compound is prepared at a concentration
of 10 mg/ml in 22.5% PEG400/1.25% Tween80/1.25%
polyvinylpyrrolidone 40/0.75% carboxymethylcellulose for 5 ml/kg,
50 mg/kg dosing. Collagen is prepared by making a 4 mg/ml solution
in 0.01N Acetic acid. Equal volumes of collagen and Freund's
incomplete adjuvant are emulsified by hand mixing until a bead of
this material holds its form when placed in water.
[1158] General Study Design:
[1159] Animals (10 rats/group for arthritis, 4 rats/group for
normal control).
[1160] Animals in the arthritis groups are anesthetized with
isoflurane and given collagen injections (D0); each animal gets 400
.mu.l of the mixture spread over 3 subcutaneous sites on the back.
On Day 6 (D6) the animals are anesthetized again and given a second
collagen injection of 200 .mu.l of the mixture spread over 3
subcutaneous sites on the back, as before.
[1161] Oral dosing of Test Compound at 12 hour intervals (bid) or
24 hour intervals (qd) is initiated on Day 0 using a dose volume of
5 ml/kg for 10 mg/ml oral solutions for 50 mg/kg dosing. Rats are
weighed on Days 0, 3, 6, and 9-17 of arthritis, and caliper
measurements of ankles taken every day beginning on Day 9 through
Day 17. Final body weights are taken on Day 17 of arthritis. On Day
17, all animals are anesthetized for terminal blood draw and then
euthanized. Subsequently, hind paws and knees are removed, the hind
paws are weighed and then (with knees) placed in formalin for
processing for microscopy. Livers, spleen and thymus and kidneys
are also removed, trimmed of extraneous tissue and weighed. Kidneys
are retained in formalin for histopathology.
[1162] Pharmacokinetic sampling is performed on Day 16.

DNBS-Induced Colitis in Rats
[1163] Procedure: Male Wistar rats weighing 200.+-.20 g are fasted
for 24 hours prior to use. Distal colitis is induced by
intra-colonic instillation of DNBS (2,4-dinotrobenzene sulfonic
acid, 20 mg in 0.5 ml ethanol 30%) with a catheter of 12 cm in
length, followed by gentle injection of air (2 ml) through the
catheter to ensure that the solution remain in the colon. The
animals are divided into groups of 5 each. Test substance and
vehicle are administered either daily or twice daily by appropriate
route of administration 24 hour and 1 hour before DNBS instillation
and then for 6 consecutive days thereafter. One normal control
group is treated with 0.9% NaCl alone without DNBS challenge. The
animals are sacrificed 12 hours after the final bid dose and 24
hours after the final daily dose and the colon is removed and
weighed. During the experiment, body weight, fecal occult blood and
stool consistency are monitored daily. Furthermore, when the
abdominal cavity is opened before removal of the colon, adhesions
between the colon and other organs are noted as is the presence of
colonic ulceration after removal and weighing of each colon (a
macroscopic damage score is recorded according to established score
criteria). The colon-to-body weight ratio is calculated according
to the formula: Colon (g)/BW.times.100. The "Net" increase in ratio
of Vehicle-control+DNBS group relative to Vehicle-control group is
used as a base for comparison with individual treated groups and
expressed as "Dec. (%)" (percent decrease). A 30% or more
(.gtoreq.30%) reduction in colon-to-body weight ratio, relative to
the vehicle treated control group, is considered significant.
[1164] Sulfasalazine is used as the standard test agent. (Hogaboam

[1167] The donor Brown Norway rats are killed to serve as donors of
5 to 8 skin transplants. Directly after killing the Brown Norway
rats, the abdominal skin of the rats is shaved and skin transplants
of 20 mm in diameter in size are taken. After removal of connective
tissue, these grafts are transplanted onto Lewis rats. This is
performed by shaving the upper dorsal skin of the Lewis rat under
isoflurane anesthesia, removing a piece of skin of 15 mm in
diameter by punching and replacement with a skin transplant derived
from the Brown Norway rat.
[1168] During the study each graft is fixated by 4-6 stitches using
Safil 6/0 violet (B Braun, Aesculap) and covered by Paraffin Gauze
Dressing BP (3.times.3 cm, Smith & Nephew), a piece of gauze
and surgical tape. This adaptation minimizes the chance of loosing
a transplant for reasons different from rejection.
[1169] In all cases, transplants are protected with a bandage;
these are removed after six days to enable daily inspection of the
transplant.
[1170] Rejection is monitored by evaluating first signs of
inflammation (redness) and necrosis (hardening and blackening of
the graft).

(X), (XI), (XIA), (XII), or (XIIA) for Prophylaxis of Acute
Rejection after Renal Transplantation
[1262] The standard immunosuppressive treatment after renal
transplantation is a combination of tacrolimus, mycophenolate
mofetil, and prednisolone. With this regimen the incidence of acute
rejection within the first six months after transplantation can
drop to about 20%. The main challenge at present remains to improve
long-term outcome by preventing chronic allograft nephropathy
(CAN). Since acute rejection is a strong predictor of CAN, a
further decrease in the incidence of acute rejection can improve
the long-term graft survival. The purpose of this phase II clinical
trial is to investigate the effectiveness and safety of a compound
of Formulas (I), (IA), (II), (IIA), (III), (IIIA), (IV), (IVA),
(V), (VA), (VI), (VIA), (VII), (VIIA), (VIII), (VIIIA), (IX),
(IXA), (X), (XI), (XIA), (XII), or (XIIA) for prophylaxis of acute
rejection after renal transplantation.

(IIIA), (IV), (IVA), (V), (VA), (VI), (VIA), (VII), (VIIA), (VIII),
(VIIIA), (IX), (IXA), (X), (XI), (XIA), (XII), or (XIIA). One group
will receive a single dose of a compound of Formulas (I), (IA),
(II), (IIA), (III), (IIIA), (IV), (IVA), (V), (VA), (VI), (VIA),
(VII), (VIIA), (VIII), (VIIIA), (IX), (IXA), (X), (XI), (XIA),

(VA), (VI), (VIA), (VII), (VIIA), (VIII), (VIIIA), (IX), (IXA),
(X), (XI), (XIA), (XII), or (XIIA) intravenously on Days 1, 15, 29,
and 43. All subjects will be seen in the clinic at regular
intervals up to Day 85 for safety, efficacy, pharmacokinetic,
and/or pharmacodynamic assessments. All subjects will be contacted
70 days after the last dose of study drug. Assessment of safety
will be determined by vital sign measurements, clinical laboratory
tests, physical examinations, immunogenicity assessments, chest
x-ray, electrocardiograms, and the incidence and severity of
treatment emergent adverse events. The primary clinical assessment
of activity will be determined by the change in Mayo score at Day
57 compared with Screening. Secondary endpoints include
determination of remission rate by the mayo score at Day 57,
evaluation of mucosal healing and change from baseline in the IBDQ
score.
