Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application is a divisional application of U.S. Ser.
No. 11/553,946 filed Oct. 27, 2006, which claims the benefit of
U.S. Provisional Application No. 60/734,030, entitled
"5-LIPOXYGENASE-ACTIVATING PROTEIN (FLAP) INHIBITORS" filed on Nov.
4, 2005; U.S. Provisional Application No. 60/747,174, entitled
"5-LIPOXYGENASE-ACTIVATING PROTEIN (FLAP) INHIBITORS", filed on May
12, 2006; and U.S. Provisional Application No. 60/823,344, entitled
"5-LIPOXYGENASE-ACTIVATING PROTEIN (FLAP) INHIBITORS", filed on
Aug. 23, 2006, all of which are herein incorporated by
reference.
FIELD OF THE INVENTION
[0002] Described herein are compounds, methods of making such
compounds, pharmaceutical compositions and medicaments comprising
such compounds, and methods of using such compounds to treat or
prevent diseases or conditions associated with
5-lipoxygenase-activating protein (FLAP) activity.
BACKGROUND OF THE INVENTION
[0003] The protein 5-lipoxygenase-activating protein (FLAP) is
associated with the pathway of leukotriene synthesis. In
particular, 5-lipoxygenase-activating protein (FLAP) is responsible
for binding arachidonic acid and transferring it to 5-lipoxygenase.
See, e.g., Abramovitz, M. et al., Eur. J. Biochem. 215:105-111
(1993). 5-lipoxygenase can then catalyze the two-step oxygenation
and dehydration of arachidonic acid, converting it into the
intermediate compound 5-HPETE (5-hydroperoxyeicosatetraenoic acid),
and in the presence of FLAP convert the 5-HPETE to Leukotriene
A.sub.4 (LTA.sub.4).
[0004] Leukotrienes are biological compounds formed from
arachidonic acid in the leukotriene synthesis pathway (Samuelsson
et al, Science, 220, 568-575, 1983; Cooper, The Cell, A Molecular
Approach, 2nd Ed. Sinauer Associates, Inc., Sunderland (MA), 2000).
They are synthesized primarily by eosinophils, neutrophils, mast
cells, basophils, dendritic cells, macrophages and monocytes.
Leukotrienes have been implicated in biological actions including,
by way of example only, smooth muscle contraction, leukocyte
activation, cytokine secretion, mucous secretion, and vascular
function.
SUMMARY OF THE INVENTION
[0005] Presented herein are methods, compounds, pharmaceutical
compositions, and medicaments for (a) diagnosing, preventing, or
treating allergic and non-allergic inflammation, (b) controlling
signs and symptoms that are associated with inflammation, and/or
(c) controlling proliferative or metabolic disorders. These
disorders may arise from genetic, iatrogeic, immunological,
infectious, metabolic, oncologic, toxic, and/or traumatic etiology.
In one aspect, the methods, compounds, pharmaceutical compositions,
and medicaments described herein comprise 5-lipoxygenase-activating
protein (FLAP) inhibitors described herein.
[0006] In one aspect provided herein are compounds of Formula (G),
pharmaceutically acceptable salts, pharmaceutically acceptable
N-oxides, pharmaceutically active metabolites, pharmaceutically
acceptable prodrugs, and pharmaceutically acceptable solvates
thereof, which antagonize or inhibit FLAP and may be used to treat
patients suffering from leukotriene-dependent conditions or
diseases, including, but not limited to, asthma, chronic
obstructive pulmonary disease, pulmonary hypertension, interstitial
lung fibrosis, rhinitis, arthritis, allergy, psoriasis,
inflammatory bowel disease, adult respiratory distress syndrome,
myocardial infarction, aneurysm, stroke, cancer, endotoxic shock,
proliferative disorders and inflammatory conditions.
[0007] Formula (G) is as follows:

may also be an "unsaturated alkyl" moiety, which means that it
contains at least one alkene or alkyne moiety. An "alkene" moiety
refers to a group consisting of at least two carbon atoms and at

that the alkyl group may consist of 1 carbon atom, 2 carbon atoms,
3 carbon atoms, etc., up to and including 10 carbon atoms, although
the present definition also covers the occurrence of the term
"alkyl" where no numerical range is designated). The alkyl group
could also be a "lower alkyl" having 1 to 5 carbon atoms. The alkyl
group of the compounds described herein may be designated as
"C.sub.1-C.sub.4 alkyl" or similar designations. By way of example
only, "C.sub.1-C.sub.4 alkyl" indicates that there are one to four
carbon atoms in the alkyl chain, i.e., the alkyl chain is selected
from the group consisting of methyl, ethyl, propyl, iso-propyl,
n-butyl, iso-butyl, sec-butyl, and t-butyl. Typical alkyl groups
include, but are in no way limited to, methyl, ethyl, propyl,

limited to: intravenous, oral, aerosol, parenteral, ophthalmic,
pulmonary and topical administration.
[0183] 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 of
any of Formula (G), Formula (G-I), or Formula (G-II), 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.

DETAILED DESCRIPTION OF THE INVENTION
Illustrative Biological Activity
[0202] Leukotrienes (LTs) are potent contractile and inflammatory
mediators produced by release of arachidonic acid from cell
membranes and conversion to leukotrienes by the action of
5-lipoxygenase, 5-lipoxygenase-activating protein, LTA.sub.4
hydrolase and LTC.sub.4 synthase. The leukotriene synthesis
pathway, or 5-lipoxygenase pathway, involves a series of enzymatic
reactions in which arachidonic acid is converted to leukotriene
LTB.sub.4, or the cysteinyl leukotrienes, LTC.sub.4, LTD.sub.4, and
LTE.sub.4. The pathway occurs mainly at the nuclear envelope and
has been described. See, e.g., Wood, J W et al, J. Exp. Med., 178:
1935-1946, 1993; Peters-Golden, Am. J. Respir. Crit. Care Med.
157:S227-S232,1998; Drazen, et al., ed. Five-Lipoxygenase Products
in Asthma, Lung Biology in Health and Disease Series, Vol. 120,
Chs. 1, 2, and 7, Marcel Dekker, Inc. NY, 1998. Protein components
dedicated to the leukotriene synthesis pathway include a
5-lipoxygenase (5-LO), a 5-lipoxygenase-activating protein, a
LTA.sub.4 hydrolase, and a LTC.sub.4 synthase. The synthesis of
leukotrienes has been described in the literature, e.g., by
Samuelsson et al, Science, 220, 568-575, 1983; Peters-Golden, "Cell
Biology of the 5-Lipoxygenase Pathway" Am J Respir Crit. Care Med
157:S227-S232 (1998). Leukotrienes are synthesized directly from
arachidonic acid by different cells including eosinophils,
neutrophils, basophils, lymphocytes, macrophages, monocytes and
mast cells. Excess LTA.sub.4, for example from an activated
neutrophil, may enter a cell by a transcellular pathway. Most cells
in the body have LTA.sub.4 hydrolase so can produce LTB.sub.4.
Platelets and endothelial cells have LTC.sub.4 synthase, so can
make LTC.sub.4 when presented with LTA.sub.4 by a transcellular
pathway.
[0203] Arachidonic acid is a polyunsaturated fatty acid and is
present mainly in the membranes of the body's cells. Upon
presentation of inflammatory stimuli from the exterior of the cell,
calcium is released and binds to phospholipase A.sub.2 (PLA2) and
5-LO. Cell activation results in the translocation of PLA.sub.2 and
5-LO from the cytoplasm to the endoplasmic reticulum and/or nuclear
membranes, where in the presence of FLAP, the released arachidonic
acid is converted via a 5-HPETE intermediate to the epoxide
LTA.sub.4. Depending on the cell type, the LTA.sub.4 may be
immediately converted to LTC.sub.4 by the nuclear-bound LTC.sub.4
synthase or to LTB.sub.4 by the action of cytosolic LTA.sub.4
hydrolase. LTB.sub.4 is exported from cells by an as yet
uncharacterized transporter and may activate other cells, or the
cell it was made in, via high affinity binding to one of two G
protein-coupled receptors (GPCRs), namely BLT.sub.1R or BLT.sub.2R.
LTC.sub.4 is exported to the blood via the MRP-1 anion pump and
rapidly converted to LTD.sub.4 by the action of .gamma.-glutamyl
transpeptidase and LTD.sub.4 is then converted to LTE.sub.4 by the
action of dipeptidases. LTC.sub.4, LTD.sub.4 and LTE.sub.4 are
collectively referred to as the cysteinyl leukotrienes (or
previously as slow reacting substance of anaphylaxis, SRS-A). The
cysteinyl leukotrienes activate other cells, or the cells they are
made in, via high affinity binding to one of two GPCRs, namely
CysLT.sub.1R or CysLT.sub.2R. CysLT.sub.1 receptors are found in
the human airway eosinophils, neutrophils, macrophages, mast cells,
B-lymphocytes and smooth muscle and induce bronchoconstriction. Zhu
et al, Am J Respir Cell Mol Biol Epub Aug. 25 (2005). CysLT.sub.2
receptors are located in human airway eosinophils, macrophages,
mast cells the human pulmonary vasculature Figueroa et al, Clin Exp
Allergy 33:1380-1388 (2003).
Involvement of Leukotrienes in Diseases or Conditions
[0204] The involvement of leukotrienes in disease is described in
detail in the literature. See e.g., by Busse, Clin. Exp. Allergy
26:868-79, 1996; O'Byrne, Chest 111(Supp. 2): 27S-34S, 1977;
Sheftell, F. D., et al., Headache, 40:158-163, 2000; Klickstein et
al., J. Clin. Invest., 66:1166-1170, 1950; Davidson et al., Ann.
Rheum. Dis., 42:677-679, 1983 Leukotrienes produce marked
inflammatory responses in human skin. Evidence for the involvement
of leukotrienes in a human disease is found in psoriasis, in which
leukotrienes have been detected in psoriatic lesions (Kragballe et
al., Arch. Dermatol., 119:548-552, 1983).
[0205] For example, inflammatory responses have been suggested to
reflect three types of changes in the local blood vessels. The
primary change is an increase in vascular diameter, which results
in an increase in local blood flow and leads to an increased
temperature, redness and a reduction in the velocity of blood flow,
especially along the surfaces of small blood vessels. The second
change is the activation of endothelial cells lining the blood
vessel to express adhesion molecules that promote the binding of
circulating leukocytes. The combination of slowed blood flow and
induced adhesion molecules allows leukocytes to attach to the
endothelium and migrate into the tissues, a process known as
extravasation. These changes are initiated by cytokines and
leukotrienes produced by activated macrophages. Once inflammation
has begun, the first cells attracted to the site of infection are
generally neutrophils. They are followed by monocytes, which
differentiate into more tissue macrophages. In the latter stages of
inflammation, other leukocytes, such as eosinophils and lymphocytes
also enter the infected site. The third major change in the local
blood vessels is an increase in vascular permeability. Instead of
being tightly joined together, the endothelial cells lining the
blood vessel walls become separated, leading to exit of fluid and
proteins from the blood and their local accumulation in the tissue.
(See Janeway, et al., Immunobiology: the immune system in health
and disease, 5th ed., Garland Publishing, New York, 2001)
[0206] LTB.sub.4 produces relatively weak contractions of isolated
trachea and lung parenchyma, and these contractions are blocked in
part by inhibitors of cyclooxygenase, suggesting that the
contraction are secondary to the release of prostaglandins.
However, LTB.sub.4 has been shown to be a potent chemotactic agent
for eosinophils and progenitors of mast cells and the LTB.sub.4
receptor BLT1 -/- knockout mouse is protected from eosinophilic
inflammation and T-cell mediated allergic airway hyperreactivity.
Miyahara et al. J Immunol 174:4979-4784; (Weller et al. J Exp Med
201:1961-1971 (2005).
[0207] Leukotrienes C.sub.4 and D.sub.4 are potent smooth muscle
contractile agents, promoting bronchoconstriction in a variety of
species, including humans (Dahlen et al., Nature, 288:484-486,
1980). These compounds have profound hemodynamic effects,
constricting coronary blood vessels, and resulting in a reduction
of cardiac output efficiency (Marone et al., in Biology of
Leukotrienes, ed. By R. Levi and R. D. Krell, Ann. New York Acad.
Sci. 524:321-333, 1988). Leukotrienes also act as vasoconstrictors,
however, marked differences exist for different vascular beds.
There are reports suggesting that leukotrienes contribute to
cardiac reperfusion injury following myocardial ischemia (Barst and
Mullane, Eur. J. Pharmacol., 114: 383-387, 1985; Sasaki et al.,
Cardiovasc. Res., 22: 142-148, 1988). LTC.sub.4 and LTD.sub.4
directly increase vascular permeability probably by promoting
retraction of capillary endothelial cells via activation of the
CysLT.sub.2 receptor and possibly other as yet undefined CysLT
receptors [Lotzer et al. Arterioscler Thromb Vasc Biol 23: e32-36.
(2003)]. LTB.sub.4 enhances atherosclerotic progression in two
atherosclerotic mouse models, namely low density receptor
lipoprotein receptor deficient (LDLr-/-) and apolipoprotein
E-deficient (ApoE-/-) mice (Aiello et al, Arterioscler Thromb Vasc
Biol 22:443-449 (2002); Subbarao et al, Arterioscler Thromb Vasc
Biol 24:369-375 (2004); Heller et al. Circulation 112:578-586
(2005). LTB.sub.4 has also been shown to increase human monocyte
chemoattractant protein (MCP-1) a known enhancer of atherosclerotic
progression (Huang et al. Aterioscler Thromb Vasc Biol 24:1783-1788
(2004).
[0208] The role of FLAP in the leukotriene synthesis pathway is
significant because FLAP in concert with 5-lipoxygenase performs
the first step in the pathway for the synthesis of leukotrienes.
Therefore the leukotriene synthesis pathway provides a number of
targets for compounds useful in the treatment of
leukotriene-dependent or leukotriene mediated diseases or
conditions, including, by way of example, vascular and inflammatory
disorders, proliferative diseases, and non-cancerous disorders.
[0209] Leukotriene-dependent or leukotriene mediated conditions
treated using the methods, compounds, pharmaceutical compositions
and medicaments described herein, include, but are not limited to,
bone diseases and disorder, cardiovascular diseases and disorders,
inflammatory diseases and disorders, dermatological diseases and
disorders, ocular diseases and disorders, cancer and other
proliferative diseases and disorders, respiratory diseases and
disorder, and non-cancerous disorders.
Treatment Options
[0210] Leukotrienes are known to contribute to the inflammation of
the airways of patients with asthma. CysLT.sub.1 receptor
antagonists such as montelukast (Singulair.TM.) have been shown to
be efficacious in asthma and allergic rhinitis [Reiss et al. Arch
Intern Med 158:1213-1220 (1998); Phillip et al. Clin Exp Allergy
32:1020-1028 (2002)]. CysLT.sub.1R antagonists pranlukast
(Onon.TM.) and zafirlukast (Accolate.TM.) have also been shown to
be efficacious in asthma.
[0211] A number of drugs have been designed to inhibit leukotriene
formation, including the 5-lipoxygenase inhibitor zileuton
(Zyflo.TM.) that has shown efficacy in asthma, Israel et al. Ann
Intern Med 119:1059-1066 (1993). The 5-lipoxygenase inhibitor
ZD2138 showed efficacy in inhibiting the fall of FEV1 resulting
from aspirin-induced asthma, Nasser et al, Thorax, 49; 749-756
(1994). The following leukotriene synthesis inhibitors have shown
efficacy in asthma: MK-0591, a specific inhibitor of
5-lipoxygenase-activating protein (FLAP), Brideau, et al., Ca. J.
Physiol. Pharmacol. 70:799-807 (1992)., MK-886, a specific
inhibitor of 5-lipoxygenase-activating protein (FLAP), Friedman et
al. Am Rev Respir Dis., 147: 839-844 (1993), and BAY X1005, a
specific inhibitor of 5-lipoxygenase-activating protein (FLAP),
Fructmann et al, Agents Actions 38: 188-195 (1993).
[0212] FLAP inhibition will decrease LTB.sub.4 from monocytes,
neutrophils and other cells involved in vascular inflammation and
thereby decrease atherosclerotic progression. The FLAP inhibitor
MK-886 has been shown to to decrease the postangioplasty
vasoconstrictive response in a porcine carotid injury model Provost
et al. Brit J Pharmacol 123: 251-258 (1998). MK-886 has also been
shown to suppress femoral artery intimal hyperplasia in a rat
photochemical model of endothelial injury Kondo et al. Thromb
Haemost 79:635-639 (1998). The 5-lipoxygenase inhibitor zileuton
has been shown to reduce renal ischemia in a mouse model, Nimesh et
al. Mol Pharm 66:220-227 (2004).
[0213] FLAP modulators have been used for the treatment of a
variety of diseases or conditions, including, by way of example

COPD and asthma", Chest 2004; 127:1553-9); (iv) increased mucosal
secretion and/or edema in a disease or condition (see e.g. Shahab R
et al., "Prostaglandins, leukotrienes, and perennial rhinitis", J
Laryngol Otol., 2004; 118; 500-7); (v) vasoconstriction,
atherosclerosis and its sequelae myocardial ischemia, myocardial
infarction, aortic aneurysm, vasculitis and stroke (see e.g. Jala

Identification of Leukotriene Synthesis Pathway Inhibitors
[0215] The development and testing of novel FLAP inhibitors which
are effective either alone or in combination with other drugs, and
which result in minimal negative side effects would be beneficial
for treating leukotriene-dependent or leukotriene mediated diseases
or conditions. Inhibitors of the leukotriene synthesis pathway
described herein may target any step of the pathway to prevent or
reduce the formation of leukotrienes. Such leukotriene synthesis
inhibitors can, by way of example, inhibit at the level of FLAP, or
5-LO, thus minimizing the formation of various products in the
leukotriene pathway, thereby decreasing the amounts of such
compounds available in the cell. Leukotriene synthesis inhibitors
can be identified based on their ability to bind to proteins in the
leukotriene synthesis pathway. For example, FLAP inhibitors can be
identified based on their binding to FLAP.

[0246] In a further or alternative embodiment, the "G" group (e.g.
G.sub.1, G.sub.5, G.sub.6, G.sub.7) is any group that is used to
tailor the physical and biological properties of the molecule. Such
tailoring/modifications are achieved using groups which modulate
acidity, basicity, lipophilicity, solubility and other physical
properties of the molecule. The physical and biological properties
modulated by such modifications to "G" include, by way of example
only, solubility, in vivo absorption, and in vivo metabolism. In
addition, in vivo metabolism may include, by way of example only,
controlling in vivo PK properties, off-target activities, potential
toxicities associated with cypP450 interactions, drug-drug
interactions, and the like. Further, modifications to "G" allow for
the tailoring of the in vivo efficacy of the compound through the
modulation of, by way of example, specific and non-specific protein
binding to plasma proteins and lipids and tissue distribution in
vivo. Additionally, such tailoring/modifications to "G" allow for
the design of compounds selective for 5-lipoxygenase-activating
protein over other proteins.
[0247] In further or alternative embodiments, "G" is L.sub.20-Q,
wherein L.sub.20 is an enzymatically cleavable linker and Q is a

[0321] Use of Protecting Groups
[0322] 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, to
avoid their unwanted participation in the reactions. Protecting
groups are used to block some or all 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. Protective groups can be
removed by acid, base, and hydrogenolysis. 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.
[0323] 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, 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.
[0324] 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.sub.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.
[0325] Typically blocking/protecting groups may be selected
from:
##STR00015##
[0326] 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 in
their entirety.
[0327] Indole containing compounds can be prepared using standard
literature procedures such as those found in Katritzky, "Handbook
of Heterocyclic Chemistry" Pergamon Press, Oxford, 1986; Pindur et
al, J. Heterocyclic Chem., vol 25, 1, 1987, and Robinson "The
Fisher Indole Synthesis", John Wiley & Sons, Chichester, N.Y.,
1982, each of which is herein incorporated by reference in thier
entirety.
[0328] A non-limiting example of the synthetic approach toward
indole compounds of Formula (G), Formula (G-I) and Formula (G-II),
is shown according to reaction Scheme I shown in FIG. 1, wherein a
4-substituted anilines (1-1) can be converted to the corresponding
hydrazine (1-2) using standard methodology. Reaction of hydrazine
(1-2) with an appropriately substituted ketone (1-3) under standard
Fisher-indolization conditions yields the indole (1-4). Indole
(1-6) results from the N-alkylation of (1-4) with a benzyl halide
(1-5) (or tosylate (OTs) or mesylate (OMs)) in a solvent such as
tetrahydrofuran (THF) or dimethylformamide (DMF) in the presense of
a base such as NaH. In the case where the 5-substituent on the
indole ring is methoxy (i.e. Z is MeO) the methyl group can be
removed under standard conditions, for example using BBr.sub.3, in
a solvent such as CH.sub.2Cl.sub.2 to afford the phenol (1-7). This
phenol can be alkylated using an electrophile (YX) to provide the
alkylated product (1-8). Alternatively, in the case when the
5-substituent on the indole ring is, for example, a halide or
triflate (OTf; 1-7) it can be coupled with a wide variety of
reagents using standard metal mediated coupling reactions well
known to those skilled in the art of organic synthesis to afford
alternate compounds of structure (1-6). Such chemistry is described
in Comprehensive Organometallic Chemistry II, vol 12, Pergamon,
edited by Abel, Stone and Wilkinson. The Z substitutent of the
indole (1-6) can be further modified using standard chemical
procedures. In addition, when R.sub.7 or R.sub.6 is a bromo or
iodine, standard cross coupling reactions allow the introduction of
a variety of functional groups using procedures well known to those
practiced in the art of organic synthesis. Furthermore, when
R.sub.7 is H, it is possible, under certain conditions, to
regioselectively lithiate using a strong base such as nBuLi and
then condense the anion with an electrophile to introduce
substituents at C-2 (see Hasan et al, J. Org. Chem., 46, 157-164,
1981).
[0329] Another non-limiting example of the synthetic approach
toward compounds of Formula (G), Formula (G-I) and Formula (G-II)
is shown according to reaction Scheme II in FIG. 2. Commencing with
the hydrazine 1-2, N-alkylation with a benzyl halide (or tosylate
or mesylate; 1-5) using the conditions described above, provides
the hydrazine derivative (II-1). Reaction with an appropriately
substituted ketone (1-3) using standard Fisher indolization
conditions provides the indole (1-6).
[0330] Another non-limiting example of the synthetic approach
toward compounds of Formula (G), Formula (G-I) and Formula (G-II)
is shown according to reaction Scheme III in FIG. 2, wherein
3-H-indoles (III-1) can be prepared directly using the procedures
described above or, alternatively, they can be prepared from
3-thioindoles by treatment with moist AlCl.sub.3 in a solvent such
as CH.sub.2Cl.sub.2. Functionalzation at the 3-position can be
achieved using a variety of reactions and procedures to allow the
introduction of a wide range of substituents. By way of example
only, acylation using an acid chloride (or anhydride) in the
presence of a Lewis acid such as AlCl.sub.3, allows for the
introduction of acyl groups (1-6; R.sub.6.dbd.C(O)R') see Murakami
et al. Heterocycles, v14, 1939-1941, 1980 and references cited
therein. Commencing with (III-1), and using, by way of example
only, sulfenic chlorides in a suitable solvent, compounds of
general structure (III-2) wherein R.sub.6 is SR'' can be prepared
(Raban, J. Org. Chem., v45, 1688, 1980). Similar chemistry using
indole (III-3) can be performed or, alternatively, diarlydisulfides
in the presence of a base such as NaH in DMF can be used to
generate (III-4) (Atkinson et al, Synthesis, 480-481, 1988). The
reaction of electron deficient olefins with 3-H indoles (III-1) or
(III-3) in the presence of a Lewis acid (such as
Yb(OTf).sub.3.3H.sub.2O) allows the installation of 3-alkyl
substituents of general structure (III-2) or (III-4) (where R.sub.6
is a substituted alkyl group; see Harrington and Kerr, Synlett,
1047-1048, 1996). Alternatively, indole (III-3) can be reacted with
benzyl derivatives (1-5) in warm DMF to yield (III-4) where R.sub.6
is a substituted benzyl group (Jacobs et al, J. Med. Chem., v36,
394-409, 1993).
Further Synthesis of Indole and Indole-Type Compounds
[0331] Additional non-limiting examples of the synthetic strategy
toward indole or indole-like scaffolds for compounds of Formula
(G), Formula (G-I) and Formula (G-II), include modifications to
various syntheses of indoles, including, but not limited to;
Batcho-Leimgruber Indole Synthesis, Reissert Indole Synthesis,
Hegedus Indole Synthesis, Fukuyama Indole Synthesis, Sugasawa
Indole Synthesis, Bischler Indole Synthesis, Gassman Indole
Synthesis, Fischer Indole Synthesis, Japp-Klingemann Indole

Bartoli Indole Synthesis, Castro Indole Synthesis, Hemetsberger
Indole Synthesis, Mori-Ban Indole Synthesis, Madelung Indole
Synthesis, Nenitzescu Indole Synthesis, and other unnamed
reactions. Non-limiting examples of such synthetic methods are
shown in FIGS. 3-7.
Further Forms of Compounds
[0332] Compounds of Formula (G), Formula (G-I) and Formula (G-II),
can be prepared as a pharmaceutically acceptable acid addition salt
(which is a type of a pharmaceutically acceptable salt) by reacting
the free base form of the compound with a pharmaceutically
acceptable inorganic or organic acid, including, but not limited
to, inorganic acids such as hydrochloric acid, hydrobromic acid,
sulfuric acid, nitric acid, phosphoric acid metaphosphoric acid,
and the like; and organic acids such as acetic acid, propionic
acid, hexanoic acid, cyclopentanepropionic acid, glycolic acid,
pyruvic acid, lactic acid, malonic acid, succinic acid, malic acid,
maleic acid, fumaric acid, p-toluenesulfonic acid, tartaric acid,
trifluoroacetic acid, citric acid, benzoic acid,
3-(4-hydroxybenzoyl)benzoic acid, cinnamic acid, mandelic acid,
arylsulfonic acid, methanesulfonic acid, ethanesulfonic acid,
1,2-ethanedisulfonic acid, 2-hydroxyethanesulfonic acid,
benzenesulfonic 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, and muconic
acid.
[0333] Alternatively, compounds of Formula (G), Formula (G-I) and
Formula (G-II), can be prepared as a pharmaceutically acceptable
base addition salts (which is a type of a pharmaceutically
acceptable salt) by reacting the free acid form of the compound
with a pharmaceutically acceptable inorganic or organic base,
including, but not limited to organic bases such as ethanolamine,
diethanolamine, triethanolamine, tromethamine, N-methylglucamine,
and the like and inorganic bases such as aluminum hydroxide,
calcium hydroxide, potassium hydroxide, sodium carbonate, sodium
hydroxide, and the like.
[0334] Compounds of Formula (G), Formula (G-I) and Formula (G-II),
can be prepared as a pharmaceutically acceptable salts formed when
an acidic proton present in the parent compound either is replaced
by a metal ion, for example an alkali metal ion, an alkaline earth
ion, or an aluminum ion; or coordinates with an organic base. In
addition, the salt forms of the disclosed compounds can be prepared
using salts of the starting materials or intermediates.
[0335] 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 of Formula (G), Formula
(G-I) and Formula (G-II), can be conveniently prepared or formed
during the processes described herein. By way of example only,
hydrates of compounds of Formula (G), Formula (G-I) and Formula
(G-II), can be conveniently prepared by recrystallization from an
aqueous/organic solvent mixture, using organic solvents including,
but not limited to, dioxane, tetrahydrofuran or methanol. 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.
[0336] Compounds of Formula (G), Formula (G-I) and Formula (G-II),
may be in various forms, including but not limited to, amorphous
forms, milled forms and nano-particulate forms. In addition,
compounds of Formula (G), Formula (G-I) and Formula (G-II), 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, infrared spectra, melting points, density,
hardness, crystal shape, optical and electrical 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.
[0337] Compounds of Formula (G), Formula (G-I) and Formula (G-II),
in unoxidized form can be prepared from N-oxides of compounds of
Formula (G), Formula (G-I) and/or Formula (G-II), by treating with
a reducing agent, such as, but not limited to, sulfur, sulfur
dioxide, triphenyl phosphine, lithium borohydride, sodium
borohydride, phosphorus trichloride, tribromide, or the like in a
suitable inert organic solvent, such as, but not limited to,
acetonitrile, ethanol, aqueous dioxane, or the like at 0 to
80.degree. C.
[0338] Compounds of Formula (G), Formula (G-I) and Formula (G-II),
can be prepared as prodrugs. Prodrugs are generally drug precursors
that, following administration to a subject and subsequent
absorption, are converted to an active, or a more active species
via some process, such as conversion by a metabolic pathway. Some
prodrugs have a chemical group present on the prodrug that renders
it less active and/or confers solubility or some other property to
the drug. Once the chemical group has been cleaved and/or modified
from the prodrug the active drug is generated. 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.
[0339] Prodrugs may be designed as reversible drug derivatives, for
use as modifiers to enhance drug transport to site-specific
tissues. The design of prodrugs to date has been to increase the
effective water solubility of the therapeutic compound for
targeting to regions where water is the principal solvent. See,
e.g., Fedorak et al., Am. J. Physiol., 269:G210-218 (1995); McLoed
et al., Gastroenterol, 106:405-413 (1994); Hochhaus et al., Biomed.
Chrom., 6:283-286 (1992); J. Larsen and H. Bundgaard, Int. J.
Pharmaceutics, 37, 87 (1987); J. Larsen et al., Int. J.
Pharmaceutics, 47, 103 (1988); Sinkula et al., J. Pharm. Sci.,
64:181-210 (1975); T. Higuchi and V. Stella, Pro-drugs as Novel
Delivery Systems, Vol. 14 of the A.C.S. Symposium Series; and
Edward B. Roche, Bioreversible Carriers in Drug Design, American
Pharmaceutical Association and Pergamon Press, 1987, all
incorporated herein in their entirety.
[0340] Additionally, prodrug derivatives of compounds of Formula
(G), Formula (G-I) and Formula (G-II), can be prepared by methods
known to those of ordinary skill in the art (e.g., for further
details see Saulnier et al., (1994), Bioorganic and Medicinal
Chemistry Letters, Vol. 4, p. 1985). By way of example only,
appropriate prodrugs can be prepared by reacting a non-derivatized
compound of any of Formula (G), Formula (G-I), or Formula (G-II),
with a suitable carbamylating agent, such as, but not limited to,
1,1-acyloxyalkylcarbanochloridate, para-nitrophenyl carbonate, or
the like. Prodrug forms of the herein described compounds, wherein
the prodrug is metabolized in vivo to produce a derivative as set
forth herein are included within the scope of the claims. Indeed,
some of the herein-described compounds may be a prodrug for another
derivative or active compound.
[0341] Sites on the aromatic ring portion of compounds of Formula
(G), Formula (G-I) and Formula (G-II), 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.
[0342] The compounds described herein may be labeled isotopically
(e.g. with a radioisotope) or by another other means, including,
but not limited to, the use of chromophores or fluorescent
moieties, bioluminescent labels, or chemiluminescent labels. The
compounds of Formula (G), Formula (G-I) and Formula (G-II), may
possess one or more stereocenters and each center may exist in the
R or S configuration. The compounds presented herein include all
diastereomeric, enantiomeric, and epimeric forms as well as the
appropriate mixtures thereof. Compounds of Formula (G), Formula
(G-I) and Formula (G-II), can be prepared as their individual
stereoisomers by reacting a racemic mixture of the compound with an
optically active resolving agent to form a pair of
diastereoisomeric compounds, separating the diastereomers and
recovering the optically pure enantiomers. While resolution of
enantiomers can be carried out using covalent diastereomeric
derivatives of the compounds described herein, dissociable
complexes are preferred (e.g., crystalline diastereomeric salts).
Diastereomers have distinct physical properties (e.g., melting
points, boiling points, solubilities, reactivity, etc.) and can be
readily separated by taking advantage of these dissimilarities. The
diastereomers can be separated by chiral chromatography, or
preferably, by separation/resolution techniques based upon
differences in solubility. The optically pure enantiomer is then
recovered, along with the resolving agent, by any practical means
that would not result in racemization. A more detailed description
of the techniques applicable to the resolution of stereoisomers of
compounds from their racemic mixture can be found in Jean Jacques,
Andre Collet, Samuel H. Wilen, "Enantiomers, Racemates and
Resolutions", John Wiley And Sons, Inc., 1981, herein incorporated
by reference in its entirety.
[0343] Additionally, the compounds and methods provided herein may
exist as geometric isomers. The compounds and methods provided
herein include all cis, trans, syn, anti, entgegen (E), and
zusammen (Z) isomers as well as the appropriate mixtures thereof.
In some situations, compounds may exist as tautomers. All tautomers
are included within the formulas described herein are provided by
compounds and methods herein. In additional embodiments of the
compounds and methods provided herein, mixtures of enantiomers
and/or diastereoisomers, resulting from a single preparative step,
combination, or interconversion may also be useful for the
applications described herein.
Routes of Administration
[0344] Suitable routes of administration include, but are not
limited to, intravenous, oral, rectal, aerosol, parenteral,
ophthalmic, pulmonary, transmucosal, transdermal, vaginal, otic,
nasal, and topical administration. In addition, by way of example
only, parenteral delivery includes intramuscular, subcutaneous,
intravenous, intramedullary injections, as well as intrathecal,
direct intraventricular, intraperitoneal, intralymphatic, and
intranasal injections.
[0345] Alternately, one may administer the compound in a local
rather than systemic manner, for example, via injection of the
compound directly into an organ, often in a depot preparation or
sustained release formulation. Such long acting formulations may be
administered by implantation (for example subcutaneously or
intramuscularly) or by intramuscular injection. Furthermore, one
may administer the drug in a targeted drug delivery system, for
example, in a liposome coated with organ-specific antibody. The
liposomes will be targeted to and taken up selectively by the
organ. In addition, the drug may be provided in the form of a rapid
release formulation, in the form of an extended release
formulation, or in the form of an intermediate release
formulation.
Pharmaceutical Composition/Formulation
[0346] Pharmaceutical compositions may be formulated in a
conventional manner using one or more physiologically acceptable
carriers comprising excipients and auxiliaries which facilitate
processing of the active compounds into preparations which can be
used pharmaceutically. Proper formulation is dependent upon the
route of administration chosen. Any of the well-known techniques,
carriers, and excipients may be used as suitable and as understood
in the art. A summary of pharmaceutical compositions described
herein may be found, for example, in Remington: The Science and
Practice of Pharmacy, Nineteenth Ed (Easton, Pa.: Mack Publishing
Company, 1995); Hoover, John E., Remington's Pharmaceutical
Sciences, Mack Publishing Co., Easton, Pa. 1975; Liberman, H. A.
and Lachman, L., Eds., Pharmaceutical Dosage Forms, Marcel Decker,
New York, N.Y., 1980; and Pharmaceutical Dosage Forms and Drug
Delivery Systems, Seventh Ed. (Lippincott Williams & Wilkins
1999), herein incorporated by reference in their entirety.
[0347] Provided herein are pharmaceutical compositions comprising a
compound of any of Formula (G), Formula (G-I), or Formula (G-II),
and a pharmaceutically acceptable diluent(s), excipient(s), or
carrier(s). In addition, the compounds described herein can be
administered as pharmaceutical compositions in which compounds of
any of Formula (G), Formula (G-I), or Formula (G-II), are mixed
with other active ingredients, as in combination therapy.
[0348] A pharmaceutical composition, as used herein, refers to a
mixture of a compound of any of Formula (G), Formula (G-I), or
Formula (G-II), with other chemical components, such as carriers,
stabilizers, diluents, dispersing agents, suspending agents,
thickening agents, and/or excipients. The pharmaceutical
composition facilitates administration of the compound to an
organism. In practicing the methods of treatment or use provided
herein, therapeutically effective amounts of compounds of any of
Formula (G), Formula (G-I), or Formula (G-II), provided herein are
administered in a pharmaceutical composition to a mammal having a
disease or condition to be treated. Preferably, the mammal is a
human. A therapeutically effective amount can vary widely depending
on the severity of the disease, the age and relative health of the
subject, the potency of the compound used and other factors. The
compounds can be used singly or in combination with one or more
therapeutic agents as components of mixtures.
[0349] For intravenous injections, compounds of any of Formula (G),
Formula (G-I), or Formula (G-II), 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 known in the art. For other parenteral
injections, appropriate formulations may include aqueous or
nonaqueous solutions, preferably with physiologically compatible
buffers or excipients. Such excipients are generally known in the
art.
[0350] For oral administration, compounds of any of Formula (G),
Formula (G-I), or Formula (G-II), can be formulated readily by
combining the active compounds with pharmaceutically acceptable
carriers or excipients well known in the art. Such carriers enable
the compounds described herein to be formulated as tablets,
powders, pills, dragees, capsules, liquids, gels, syrups, elixirs,
slurries, suspensions and the like, for oral ingestion by a patient
to be treated.
[0351] Pharmaceutical preparations for oral use can be obtained by
mixing one or more solid excipient with one or more of the
compounds described herein, optionally grinding the resulting
mixture, and processing the mixture of granules, after adding
suitable auxiliaries, if desired, to obtain tablets or dragee
cores. Suitable excipients are, in particular, fillers such as
sugars, including lactose, sucrose, mannitol, or sorbitol;
cellulose preparations such as: for example, maize starch, wheat
starch, rice starch, potato starch, gelatin, gum tragacanth,
methylcellulose, microcrystalline cellulose,
hydroxypropylmethylcellulose, sodium carboxymethylcellulose; or
others such as: polyvinylpyrrolidone (PVP or povidone) or calcium
phosphate. If desired, disintegrating agents may be added, such as
the cross-linked croscarmellose sodium, polyvinylpyrrolidone, agar,
or alginic acid or a salt thereof such as sodium alginate.
[0352] Dragee cores are provided with suitable coatings. For this
purpose, concentrated sugar solutions may be used, which may
optionally contain gum arabic, talc, polyvinylpyrrolidone, carbopol
gel, polyethylene glycol, and/or titanium dioxide, lacquer
solutions, and suitable organic solvents or solvent mixtures.
Dyestuffs or pigments may be added to the tablets or dragee
coatings for identification or to characterize different
combinations of active compound doses.
[0353] Pharmaceutical preparations which can be used orally include
push-fit capsules made of gelatin, as well as soft, sealed capsules
made of gelatin and a plasticizer, such as glycerol or sorbitol.
The push-fit capsules can contain the active ingredients in
admixture with filler such as lactose, binders such as starches,
and/or lubricants such as talc or magnesium stearate and,
optionally, stabilizers. In soft capsules, the active compounds may
be dissolved or suspended in suitable liquids, such as fatty oils,
liquid paraffin, or liquid polyethylene glycols. In addition,
stabilizers may be added. All formulations for oral administration
should be in dosages suitable for such administration.
[0354] For buccal or sublingual administration, the compositions
may take the form of tablets, lozenges, or gels formulated in a
conventional manner Parental 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 of any
of Formula (G), Formula (G-I), or Formula (G-II), 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.
[0355] The compounds of any of Formula (G), Formula (G-I), or
Formula (G-II), can be administered topically and can be 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.
[0356] Formulations suitable for transdermal administration of
compounds having the structure of any of Formula (G), Formula
(G-I), or Formula (G-II), 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 of any
of Formula (G), Formula (G-I), or Formula (G-II), can be
accomplished by means of iontophoretic patches and the like.
Additionally, transdermal patches can provide controlled delivery
of the compounds any of Formula (G), Formula (G-I), or Formula
(G-II). 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.
[0357] For administration by inhalation, the compounds of any of
Formula (G), Formula (G-I), or Formula (G-II), maybe in a form as
an aerosol, a mist or a powder. Pharmaceutical compositions of any
of Formula (G), Formula (G-I), or Formula (G-II), 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 and a suitable powder base such as lactose or
starch.
[0358] The compounds of any of Formula (G), Formula (G-I), or
Formula (G-II), 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.
[0359] Pharmaceutical compositions may be formulated in
conventional manner using one or more physiologically acceptable
carriers comprising excipients and auxiliaries which facilitate
processing of the active compounds into preparations which can be
used pharmaceutically. Proper formulation is dependent upon the
route of administration chosen. Any of the well-known techniques,
carriers, and excipients may be used as suitable and as understood
in the art. Pharmaceutical compositions comprising a compound of
any of Formula (G), Formula (G-I), or Formula (G-II), may be
manufactured in a conventional manner, such as, by way of example
only, by means of conventional mixing, dissolving, granulating,
dragee-making, levigating, emulsifying, encapsulating, entrapping
or compression processes.
[0360] The pharmaceutical compositions will include at least one
pharmaceutically acceptable carrier, diluent or excipient and a
compound of any of Formula (G), Formula (G-I), or Formula (G-II),
described herein as an active ingredient in free-acid or free-base
form, or in a pharmaceutically acceptable salt form. In addition,
the methods and pharmaceutical compositions described herein
include the use of N-oxides, crystalline forms (also known as
polymorphs), as well as active metabolites of these compounds
having the same type of activity. In some situations, compounds may
exist as tautomers. All tautomers are included within the scope of
the compounds presented herein. Additionally, 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. In addition, the
pharmaceutical compositions may include other medicinal or
pharmaceutical agents, carriers, adjuvants, such as preserving,
stabilizing, wetting or emulsifying agents, solution promoters,
salts for regulating the osmotic pressure, and/or buffers. In
addition, the pharmaceutical compositions can also contain other
therapeutically valuable substances.
[0361] Methods for the preparation of compositions comprising the
compounds described herein include formulating the compounds with
one or more inert, pharmaceutically acceptable excipients or
carriers to form a solid, semi-solid or liquid. Solid compositions
include, but are not limited to, powders, tablets, dispersible
granules, capsules, cachets, and suppositories. Liquid compositions
include solutions in which a compound is dissolved, emulsions
comprising a compound, or a solution containing liposomes,
micelles, or nanoparticles comprising a compound as disclosed
herein. Semi-solid compositions include, but are not limited to,
gels, suspensions and creams. The compositions may be in liquid
solutions or suspensions, solid forms suitable for solution or
suspension in a liquid prior to use, or as emulsions. These
compositions may also contain minor amounts of nontoxic, auxiliary
substances, such as wetting or emulsifying agents, pH buffering
agents, and so forth.
[0362] A composition comprising a compound of any of Formula (G),
Formula (G-I), or Formula (G-II), can illustratively take the form
of a liquid where the agents are present in solution, in suspension
or both. Typically when the composition is administered as a
solution or suspension a first portion of the agent is present in
solution and a second portion of the agent is present in
particulate form, in suspension in a liquid matrix. In some
embodiments, a liquid composition may include a gel formulation. In
other embodiments, the liquid composition is aqueous.
[0363] Useful aqueous suspension can also contain one or more
polymers as suspending agents. Useful polymers include
water-soluble polymers such as cellulosic polymers, e.g.,
hydroxypropyl methylcellulose, and water-insoluble polymers such as
cross-linked carboxyl-containing polymers. Useful compositions can
also comprise an mucoadhesive polymer, selected for example from
carboxymethylcellulose, carbomer (acrylic acid polymer),
poly(methylmethacrylate), polyacrylamide, polycarbophil, acrylic
acid/butyl acrylate copolymer, sodium alginate and dextran.
[0364] Useful compositions may also include solubilizing agents to
aid in the solubility of a compound of any of Formula (G), Formula
(G-I), or Formula (G-II). The term "solubilizing agent" generally
includes agents that result in formation of a micellar solution or
a true solution of the agent. Certain acceptable nonionic
surfactants, for example polysorbate 80, can be useful as
solubilizing agents, as can ophthalmically acceptable glycols,
polyglycols, e.g., polyethylene glycol 400, and glycol ethers.
[0365] Useful compositions may also include one or more pH
adjusting agents or buffering agents, including acids such as
acetic, boric, citric, lactic, phosphoric and hydrochloric acids;
bases such as sodium hydroxide, sodium phosphate, sodium borate,
sodium citrate, sodium acetate, sodium lactate and
tris-hydroxymethylaminomethane; and buffers such as
citrate/dextrose, sodium bicarbonate and ammonium chloride. Such
acids, bases and buffers are included in an amount required to
maintain pH of the composition in an acceptable range.
[0366] Useful compositions may also include one or more salts in an
amount required to bring osmolality of the composition into an
acceptable range. Such salts include those having sodium, potassium
or ammonium cations and chloride, citrate, ascorbate, borate,
phosphate, bicarbonate, sulfate, thiosulfate or bisulfite anions;
suitable salts include sodium chloride, potassium chloride, sodium
thiosulfate, sodium bisulfite and ammonium sulfate.
[0367] Other useful compositions may also include one or more
preservatives to inhibit microbial activity. Suitable preservatives
include mercury-containing substances such as merfen and
thiomersal; stabilized chlorine dioxide; and quaternary ammonium
compounds such as benzalkonium chloride, cetyltrimethylammonium
bromide and cetylpyridinium chloride.
[0368] Still other useful compositions may include one or more
surfactants to enhance physical stability or for other purposes.
Suitable nonionic surfactants include polyoxyethylene fatty acid
glycerides and vegetable oils, e.g., polyoxyethylene (60)
hydrogenated castor oil; and polyoxyethylene alkylethers and
alkylphenyl ethers, e.g., octoxynol 10, octoxynol 40.
[0369] Still other useful compositions may include one or more
antioxidants to enhance chemical stability where required. Suitable
antioxidants include, by way of example only, ascorbic acid and
sodium metabisulfite.
[0370] 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.
[0371] Alternatively, other delivery systems for hydrophobic
pharmaceutical compounds may be employed. Liposomes and emulsions
are well known examples of delivery vehicles or carriers for
hydrophobic drugs. Certain organic solvents such as
N-methylpyrrolidone also may be employed, although usually at the
cost of greater toxicity. Additionally, the compounds may be
delivered using a sustained-release system, such as semipermeable
matrices of solid hydrophobic polymers containing the therapeutic
agent. Various sustained-release materials have been established
and are well known by those skilled in the art. Sustained-release
capsules may, depending on their chemical nature, release the
compounds for a few weeks up to over 100 days. Depending on the
chemical nature and the biological stability of the therapeutic
reagent, additional strategies for protein stabilization may be
employed.
[0372] All of the formulations described herein may benefit from
antioxidants, metal chelating agents, thiol containing compounds
and other general stabilizing agents. Examples of such stabilizing
agents, include, but are not limited to: (a) about 0.5% to about 2%
w/v glycerol, (b) about 0.1% to about 1% w/v methionine, (c) about
0.1% to about 2% w/v monothioglycerol, (d) about 1 mM to about 10
mM EDTA, (e) about 0.01% to about 2% w/v ascorbic acid, (f) 0.003%
to about 0.02% w/v polysorbate 80, (g) 0.001% to about 0.05% w/v.
polysorbate 20, (h) arginine, (i) heparin, (j) dextran sulfate, (k)
cyclodextrins, (l) pentosan polysulfate and other heparinoids, (m)
divalent cations such as magnesium and zinc; or (n) combinations
thereof.
Methods of Dosing and Treatment Regimens
[0373] The compounds of Formula (G), Formula (G-I), and Formula
(G-II), can be used in the preparation of medicaments for the
treatment of leukotriene-dependent or leukotriene mediated diseases
or conditions. 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 of any of Formula
(G), Formula (G-I), or Formula (G-II), or a pharmaceutically
acceptable salt, pharmaceutically acceptable N-oxide,
pharmaceutically active metabolite, pharmaceutically acceptable
prodrug, or pharmaceutically acceptable solvate thereof, in
therapeutically effective amounts to said subject
[0374] 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. It is considered
well within the skill of the art for one to determine such
therapeutically effective amounts by routine experimentation
(including, but not limited to, a dose escalation clinical
trial).
[0375] 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. It is considered well within the skill of the
art for one to determine such prophylactically effective amounts by
routine experimentation (e.g., a dose escalation clinical trial).
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.
[0376] 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.
[0377] 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, and 365 days. The
dose reduction during a drug holiday may be from 10%-100%,
including by way of example only 10%, 15%, 20%, 25%, 30%, 35%, 40%,
45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, and
100%.
[0378] 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.
[0379] The amount of a given agent that will correspond to such an
amount will vary depending upon factors such as the particular
compound, disease condition and its severity, the identity (e.g.,
weight) of the subject or host in need of treatment, but can
nevertheless be routinely determined in a manner known in the art
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 0.02-5000 mg per
day, preferably 1-1500 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.
[0380] 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.
[0381] The daily dosages appropriate for the compounds of Formula
(G), Formula (G-I), and Formula (G-II), described herein are from
about 0.01 to 2.5 mg/kg per body weight. 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 100 mg, conveniently
administered 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 comprise from about 1 to 50 mg active
ingredient. 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.
[0382] 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.
Use of FLAP Modulators to Prevent and/or Treat
Leukotriene-Dependent or Leukotriene Mediated Diseases or
Conditions
[0383] The therapy of leukotriene-dependent or leukotriene mediated
diseases or conditions is designed to modulate the activity of
FLAP. Such modulation may include, by way of example only,
inhibiting or antagonizing FLAP activity. For example, a FLAP
inhibitor can be administered in order to decrease synthesis of
leukotrienes within the individual, or possibly to downregulate or
decrease the expression or availability of the FLAP mRNA or
specific splicing variants of the FLAP mRNA. Downregulation or
decreasing expression or availability of a native FLAP mRNA or of a
particular splicing variant could minimize the expression or
activity of a defective nucleic acid or the particular splicing
variant and thereby minimize the impact of the defective nucleic
acid or the particular splicing variant.
[0384] In accordance with one aspect, compositions and methods
described herein include compositions and methods for treating,
preventing, reversing, halting or slowing the progression of
leukotriene-dependent or leukotriene mediated diseases or
conditions once it becomes clinically evident, or treating the
symptoms associated with or related to leukotriene-dependent or
leukotriene mediated diseases or conditions, by administering to
the subject a compound of any of Formula (G), Formula (G-I), or
Formula (G-II), or pharmaceutical composition or medicament which
includes a compound of any of Formula (G), Formula (G-I), or
Formula (G-II). The subject may already have a
leukotriene-dependent or leukotriene mediated disease or condition
at the time of administration, or be at risk of developing a
leukotriene-dependent or leukotriene mediated disease or condition.
The symptoms of leukotriene-dependent or leukotriene mediated
diseases or conditions in a subject can be determined by one
skilled in the art and are described in standard textbooks.
[0385] The activity of 5-lipoxygenase activating protein in a
mammal may be directly or indirectly modulated by the
administration of (at least once) an effective amount of at least
one compound of any of Formula (G), Formula (G-I), or Formula
(G-II), or pharmaceutical composition or medicament which includes
a compound of any of Formula (G), Formula (G-I), or Formula (G-II),
to a mammal Such modulation includes, but is not limited to,
reducing and/or inhibiting the activity of 5-lipoxygenase
activating protein. In addition, the activity of leukotrienes in a
mammal may be directly or indirectly modulated, including reducing
and/or inhibiting, by the administration of (at least once) an
effective amount of at least one compound of any of Formula (G),
Formula (G-I), or Formula (G-II), or pharmaceutical composition or
medicament which includes a compound of any of Formula (G), Formula
(G-I), or Formula (G-II), to a mammal. Such modulation includes,
but is not limited to, reducing and/or inhibiting the activity of
5-lipoxygenase activating protein.

Combination Treatments
[0408] In certain instances, it may be appropriate to administer at
least one compound of any of Formula (G), Formula (G-I), or Formula
(G-II), 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 is inflammation, then it
may be appropriate to administer an anti-inflammatory 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 of 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. By way of example only,
in a treatment for asthma involving administration of one of the
compounds described herein, increased therapeutic benefit may
result by also providing the patient with other therapeutic agents
or therapies for asthma. 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.
[0409] It is known to those of skill in the art that
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. A combination
treatment regimen may encompasses treatment regimens in which
administration of a FLAP or 5-LO inhibitor described herein is
initiated prior to, during, or after treatment with a second agent
described above, and continues until any time during treatment with
the second agent or after termination of treatment with the second
agent. It also includes treatments in which a FLAP or 5-LO
inhibitor described herein and the second agent being used in
combination are administered simultaneously or at different times
and/or at decreasing or increasing intervals during the treatment
period. Combination treatment further includes periodic treatments
that start and stop at various times to assist with the clinical
management of the patient. For example, a FLAP or 5-LO inhibitor
described herein in the combination treatment can be administered
weekly at the onset of treatment, decreasing to biweekly, and
decreasing further as appropriate.
[0410] Compositions and methods for combination therapy are
provided herein. In accordance with one aspect, the pharmaceutical
compositions disclosed herein are used to treat
leukotriene-dependent or leukotriene mediated conditions. In
accordance with another aspect, the pharmaceutical compositions
disclosed herein are used to treat respiratory diseases, where
treatment with a FLAP inhibitor is indicated, in particular asthma,
and to induce bronchodilation in a subject. In one embodiment,
pharmaceutical compositions disclosed herein are used to treat a
subject suffering from a vascular inflammation-driven disorder. In
one embodiment, the pharmaceutical compositions disclosed herein
are used to treat a subject susceptible to myocardial infarction
(MI).
[0411] Combination therapies described herein can be used as part
of a specific treatment regimen intended to provide a beneficial
effect from the co-action of a FLAP inhibitors described herein and
a concurrent treatment. 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 type of respiratory disorder and the type
of bronchodilation 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.
[0412] 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).
[0413] In any case, the multiple therapeutic agents (one of which
is one of the compounds 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.
[0414] In addition, the compounds of any of Formula (G), Formula
(G-I), or Formula (G-II), may also 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 any of Formula (G),
Formula (G-I), or Formula (G-II), 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.
[0415] The compounds of any of Formula (G), Formula (G-I), or
Formula (G-II), 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 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 about 1 month 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, and more preferably from
about 1 month to about 3 years.
[0416] By way of example, therapies which combine compounds of any
of Formula (G), Formula (G-I), or Formula (G-II), with inhibitors
of leukotriene synthesis or leukotriene receptor antagonists,
either acting at the same or other points in the leukotriene
synthesis pathway, could prove to be particularly useful for
treating leukotriene-dependent or leukotriene mediated diseases or
conditions. In addition, by way of example, therapies which combine
compounds of any of Formula (G), Formula (G-I), or Formula (G-II),
with inhibitors of inflammation could prove to be particularly
useful for treating leukotriene-dependent or leukotriene mediated
diseases or conditions.
[0417] Anti-Inflammatory Agents
[0418] In another embodiment described herein, methods for
treatment of leukotriene-dependent or leukotriene mediated
conditions or diseases includes administered to a patient
compounds, pharmaceutical compositions, or medicaments described
herein in combination with an anti-inflammatory agent including,
but not limited to, arthrotec, asacol, auralglan, azulfidine,
daypro, etodolac, ponstan, salofalk, and solumedrol; non-steroidal
anti-inflammatory agents, by way of example, aspirin (Bayer.TM.,
Bufferin.TM.), indomethacin (Indocin.TM.), rofecoxib (Vioxx.TM.),
celecoxib (Celebrex.TM.), valdecoxib (Bextra.TM.), diclofenac,
etodolac, ketoprofen, Iodine, mobic, nabumetone, naproxen,
piroxicam; and corticosteroids, by way of example, celestone,
prednisone, and deltasone. Corticosteroids do not directly inhibit
leukotriene production, therefore co-dosing with steroids could
provide additional anti-inflammatory benefit.
[0419] By way of example, asthma is a chronic inflammatory disease
characterized by pulmonary eosinophilia and airway
hyperresponsiveness. Zhao et al., Proteomics, Jul. 4, 2005. In
patients with asthma, leukotrienes may be released from mast cells,
eosinophils, and basophils. The leukotrienes are involved in
contraction of airway smooth muscle, an increase in vascular
permeability and mucus secretions, and have been reported to
attract and activate inflammatory cells in the airways of
asthmatics (Siegel et al., ed., Basic Neurochemistry, Molecular,
Cellular and Medical Aspects, Sixth Ed., Lippincott Williams &
Wilkins, 1999). Thus, in another embodiment described herein, the
methods for treatment of respiratory diseases includes
administration to a patient compounds, pharmaceutical compositions,
or medicaments described herein in combination with an
anti-inflammatory agent.
[0420] Leukotriene Receptor Antagonists
[0421] In another embodiment described herein, methods for
treatment of leukotriene-dependent or leukotriene mediated
conditions or diseases includes administered to a patient
compounds, pharmaceutical compositions, or medicaments described
herein in combination with leukotriene receptor antagonists
including, but are not limited to, CysLT.sub.1/CysLT.sub.2 dual
receptor antagonists and CysLT.sub.1 receptor anatagonists. In
another embodiment described herein, methods for treatment of
leukotriene-dependent or leukotriene mediated conditions or
diseases includes administered to a patient compounds,
pharmaceutical compositions, or medicaments described herein in
combination with a CysLT.sub.1/CysLT.sub.2 dual receptor
antagonist. CysLT.sub.1/CysLT.sub.2 dual receptor antagonists
include, but are not limited to, BAY u9773, Cuthbert et al EP
00791576 (published 27 Aug. 1997), DUO-LT (Galczenski et al, D38,
Poster F4 presented at American Thoracic Society, May 2002) and
Tsuji et al, Org. Biomol. Chem., 1, 3139-3141, 2003. For a
particular patient, the most appropriate formulation or method of
use of such combination treatments may depend on the type of
leukotriene-dependent or leukotriene mediated disorder, the time
period in which the FLAP inhibitor acts to treat the disorder and
the time period in which the CysLT.sub.1/CysLT.sub.2 dual receptor
antagonist acts to inhibit CysLT receptor activity. By way of
example only, such combination treatments may be used for treating
a patient suffering from a respiratory disorders.
[0422] In another embodiment described herein, methods for
treatment of leukotriene-dependent or leukotriene mediated
conditions or diseases includes administered to a patient
compounds, pharmaceutical compositions, or medicaments described
herein in combination with a CysLT.sub.1 receptor antagonist.
CysLT.sub.1 receptor antagonists include, but are not limited to,
Zafirlukast ("Accolate.TM."), Montelukast ("Singulair.TM."),
Prankulast ("Onon.TM."), and derivatives or analogs thereof. Such
combinations may be used to treat leukotriene-dependent or
leukotriene mediated disorder, including respiratory disorders.
[0423] The co-administration of a FLAP or 5-LO inhibitor described
herein with a CysLT.sub.1 receptor antagonist or a dual
CysLT.sub.1/CysLT.sub.2 receptor antagonist may have therapeutic
benefit over and above the benefit derived from the administration
of a either a FLAP or 5-LO inhibitor or a CysLT.sub.1R antagonist
alone. In the case that substantial inhibition of leukotriene
production has undesired effects, partial inhibition of this
pathway through the amelioration of the effects of the
proinflammatory LTB.sub.4 and cysteinyl leukotrienes combined with
the block of the CysLT.sub.1 receptor and/or dual
CysLT.sub.1/CysLT.sub.2 receptor block may afford substantial
therapeutic benefits, particularly for respiratory diseases.

[0425] In another embodiment described herein, methods for
treatment of leukotriene-dependent or leukotriene mediated
conditions or diseases, such as proliferative disorders, including

compositions, or medicaments described herein in combination with
at least one additional agent selected from anti-inflammatory
agents, such as corticosteroids, azathioprine or

[0432] Treatment of Leukotriene based conditions or diseases using
CysLT.sub.1/CysLT.sub.2 Receptor Antagonists
[0433] In accordance with another aspect, the compositions and
methods described herein are designed to deliver a
CysLT.sub.1/CysLT.sub.2 dual receptor antagonist to block the CysLT
receptor activity. The term "CysLT antagonist" or "CysLT receptor
antagonist" or "leukotriene receptor antagonist" refers to a
therapy that decreases the signaling of CysLTs through CysLT
receptors. CysLT typically refers to either LTC.sub.4, LTD.sub.4 or
LTE.sub.4. Cysteinyl leukotrienes are potent smooth muscle
constricting agents, particularly in respiratory and circulatory
systems. These are mediated via at least two cell receptors,
CysLT.sub.1 and CysLT.sub.2. The CysLT.sub.1 receptor and
CysLT.sub.2 receptors are G-protein-coupled receptors with seven
putative transmembrane regions and an intracellular domain that
interacts with G-proteins, Evans et al, Prostaglandins and Other
Lipid Mediators, 68-69, p587-597, (2002). Examples of
CysLT.sub.1/CysLT.sub.2 dual receptor antagonists are BAY u9773,
Cuthbert et al EP 00791576 (published 27 Aug. 1997), DUO-LT
(Galczenski et al, D38, Poster F4 presented at American Thoracic
Society, May 2002) and Tsuji et al, Org. Biomol. Chem., 1,
3139-3141, 2003.
[0434] In certain embodiments, methods for treatment of
leukotriene-dependent or leukotriene mediated diseases or
conditions includes administering to patients compounds,
pharmaceutical compositions, or medicaments comprising a
CysLT.sub.1/CysLT.sub.2 receptor antagonist. By way of example,
such compounds, pharmaceutical compositions, or medicaments may be
used as treatment and/or prevention for respiratory diseases
including, but not limited to, chronic stable asthma.
[0435] Diagnostic Methods for Patient Identification
[0436] The screening of "leukotriene-responsive patients" which may
be selected for treatment with compounds of any of Formula (G),
Formula (G-I), or Formula (G-II), or pharmaceutical compositions or
medicaments described herein which include compounds of any of
Formula (G), Formula (G-I), or Formula (G-II), or other FLAP
modulators, may be accomplished using techniques and methods
described herein. Such techniques and methods include, by way of
example, evaluation of gene haplotypes (genotype analysis),
monitoring/measurement of biomarkers (phenotype analysis),
monitoring/measurement of functional markers (phenotype analysis),
which indicate patient response to known modulators of the
leukotriene pathway, or any combination thereof.
[0437] Genotype Analysis: FLAP Polymorphisms
[0438] Human FLAP has been purified and cloned and is an 18
kilodalton membrane-bound protein which is most highly expressed in
human neutrophils. The FLAP gene is located at 13q12 and the gene
has been linked to increased risk for both myocardial infarction
and stroke in several populations. A number of polymorphisms and
haplotypes in the gene encoding FLAP have been identified in
individuals (U.S. Patent Application 2005113408; Sayers, Clin. Exp.
Allergy, 33(8):1103-10, 2003; Kedda, et al., Clin. Exp. Allergy,
35(3):332-8, 2005). Particular FLAP haplotypes have been linked to
myocardial infarction and stroke in several populations
(Helgadottir A et al. Nature Genet. 36:233-239 (2004); Helgadottir
A et al. Am J Hum Genet. 76:505-509 (2004); Lohmussaar E et al.
Stroke 36: 731-736 (2005); Kajimoto K et al. Circ J 69:1029-1034
(2005). Previously, polymorphisms in certain genes have been
demonstrated to correlate with responsiveness to given therapies,
for example, the responsiveness of cancers to particular
chemotherapeutic agents (Erichsen, et al., Br. J. Cancer,
90(4):747-51, 2004; Sullivan, et al., Oncogene, 23(19):3328-37,
2004). Therefore, patients who are under consideration for
treatment with the novel FLAP inhibitors described herein, or drug
combinations that include such novel FLAP inhibitors, may be
screened for potential responsiveness to treatment based on their
FLAP polymorphisms, or haplotypes.
[0439] Additionally, polymorphisms in any of the synthetic or
signaling genes dedicated to the leukotriene pathway could result
in a patient who is more responsive or less responsive to
leukotriene modulator therapy (either FLAP or 5-LO inhibitor or
leukotriene receptor antagonists). The genes dedicated to the
leukotriene pathway are 5-lipoxygenase, 5-lipoxygenase-activating
protein, LTA.sub.4 hydrolase, LTC.sub.4 synthase, LTB.sub.4
receptor 1 (BLT.sub.1), LTB.sub.4 receptor 2 (BLT.sub.2), cysteinyl
leukotriene receptor 1 (CysLT.sub.1R), cysteinyl leukotriene
receptor 2 (CysLT.sub.2R). For example, the 5-LO gene has been
linked to aspirin intolerant asthma and airway hyperresponsiveness
(Choi J H et al. Hum Genet. 114:337-344 (2004); Kim, S H et al.
Allergy 60:760-765 (2005). Genetic variants in the promoter region
of 5-LO have been shown to predict clinical responses to a 5LO
inhibitor in asthmatics (Drazen et al, Nature Genetics, 22,
p168-170, (1999). The LTC.sub.4 synthase gene has been linked to
atopy and asthma (Moissidis I et al. Genet Med 7:406-410 (2005).
The CysLT.sub.2 receptor has been linked to asthma and atopy
(Thompson M D et al. Pharmacogenetics 13:641-649 (2003); Pillai S G
et al. Pharmacogenetics 14:627-633 (2004); Park J S et al.
Pharmacogenet Genomics 15:483-492 (2005); Fukai H et al.
Pharmacogenetics 14:683-690 (2004). Any polymorphisms in any
leukotriene pathway gene or combination of polymorphisms or
haplotypes may result in altered sensitivity of the patient to
therapy aimed at reducing the pathological effects of leukotrienes.
Selection of patients who might best respond to the leukotriene
modulator therapies described herein may include knowledge of
polymorphisms in the leukotriene pathway genes and also knowledge
of the expression of leukotriene-driven mediators. Patient
selection could be made on the basis of leukotriene pathway
genotype alone, phenotype alone (biomarkers or functional markers)
or any combination of genotype and phenotype.
[0440] A "haplotype," as described herein, refers to a combination
of genetic markers ("alleles"). A haplotype can comprise one or
more alleles (e.g., a haplotype containing a single SNP), two or
more alleles, three or more alleles, four or more alleles, or five
or more alleles. The genetic markers are particular "alleles" at
"polymorphic sites" associated with FLAP. A nucleotide position at
which more than one sequence is possible in a population is
referred to herein as a "polymorphic site." Where a polymorphic
site is a single nucleotide in length, the site is referred to as a
single nucleotide polymorphism ("SNP"). For example, if at a
particular chromosomal location, one member of a population has an
adenine and another member of the population has a thymine at the
same position, then this position is a polymorphic site, and, more
specifically, the polymorphic site is a SNP. Polymorphic sites can
allow for differences in sequences based on substitutions,
insertions or deletions. Each version of the sequence with respect
to the polymorphic site is referred to herein as an "allele" of the
polymorphic site. Thus, in the previous example, the SNP allows for
both an adenine allele and a thymine allele.
[0441] Typically, a reference sequence is referred to for a
particular sequence. Alleles that differ from the reference are
referred to as "variant" alleles. The term "variant FLAP" as used
herein, refers to a sequence that differs from a reference FLAP
sequence, but is otherwise substantially similar. The genetic
markers that make up the haplotypes described herein are FLAP
variants. In certain embodiments the FLAP variants are at least
about 90% similar to a reference sequence. In other embodiments the
FLAP variants are at least about 91% similar to a reference
sequence. In other embodiments the FLAP variants are at least about
92% similar to a reference sequence. In other embodiments the FLAP
variants are at least about 93% similar to a reference sequence. In
other embodiments the FLAP variants are at least about 94% similar
to a reference sequence. In other embodiments the FLAP variants are
at least about 95% similar to a reference sequence. In other
embodiments the FLAP variants are at least about 96% similar to a
reference sequence. In other embodiments the FLAP variants are at
least about 97% similar to a reference sequence. In other
embodiments the FLAP variants are at least about 98% similar to a
reference sequence. In other embodiments the FLAP variants are at
least about 99% similar to a reference sequence.
[0442] Additionally, in certain embodiments the FLAP variants
differ from the reference sequence by at least one base, while in
other embodiments the FLAP variants differ from the reference
sequence by at least two bases. In other embodiments the FLAP
variants differ from the reference sequence by at least three
bases, and in still other embodiments the FLAP variants differ from
the reference sequence by at least four bases.
[0443] Additional variants can include changes that affect a
polypeptide, e.g., the FLAP polypeptide. The polypeptide encoded by
a reference nucleotide sequence is the "reference" polypeptide with
a particular reference amino acid sequence, and polypeptides
encoded by variant alleles are referred to as "variant"
polypeptides with variant amino acid sequences. The FLAP nucleic
acid sequence differences, when compared to a reference nucleotide
sequence, can include the insertion or deletion of a single
nucleotide, or of more than one nucleotide, resulting in a frame
shift; the change of at least one nucleotide, resulting in a change
in the encoded amino acid; the change of at least one nucleotide,
resulting in the generation of a premature stop codon; the deletion
of several nucleotides, resulting in a deletion of one or more
amino acids encoded by the nucleotides; the insertion of one or
several nucleotides, such as by unequal recombination or gene
conversion, resulting in an interruption of the coding sequence;
duplication of all or a part of a sequence; transposition; or a
rearrangement of a nucleotide sequence, as described in detail
above. Such sequence changes alter the polypeptide encoded by a
FLAP nucleic acid. For example, if the change in the nucleic acid
sequence causes a frame shift, the frame shift can result in a
change in the encoded amino acids, and/or can result in the
generation of a premature stop codon, causing generation of a
truncated polypeptide.
[0444] By way of example, a polymorphism associated with a
susceptibility to myocardial infarction (MI), acute coronary
syndrome (ACS), stroke or peripheral arterial occlusive disease
(PAOD) can be a synonymous change in one or more nucleotides (i.e.,
a change that does not result in a change in the amino acid
sequence). Such a polymorphism can, for example, alter splice
sites, decrease or increase expression levels, affect the stability
or transport of mRNA, or otherwise affect the transcription or
translation of the polypeptide. The haplotypes described below are
found more frequently in individuals with MI, ACS, stroke or PAOD
than in individuals without MI, ACS, stroke or PAOD. Therefore,
these haplotypes may have predictive value for detecting a
susceptibility to MI, ACS, stroke or PAOD in an individual.
[0445] Several variants of the FLAP gene have been reported to
correlate with the incidence of myocardial infarction in patients
(Hakonarson, JAMA, 293(18):2245-56, 2005), plus FLAP gene markers
reportedly associated with the risk for developing asthma have been
described in U.S. Pat. No. 6,531,279. Methods for identifying FLAP
sequence variants are described, e.g., in U.S. Publication No.
2005/0113408, and in U.S. Pat. No. 6,531,279, incorporated herein
by reference herein in their entirety.
[0446] By way of example only, a haplotype associated with a
susceptibility to myocardial infarction or stroke comprises markers
SG13S99, SG13S25, SG13S377, SG13S106, SG13S32 and SG13S35 at the
13q12-13 locus. Or, the presence of the alleles T, G, G, G, A and G
at SG13S99, SG13S25, SG13S377, SG13S106, SG13S32 and SG13S35,
respectively (the B6 haplotype), is diagnostic of susceptibility to
myocardial infarction or stroke. Or, a haplotype associated with a
susceptibility to myocardial infarction or stroke comprises markers
SG13S99, SG13S25, SG13S106, SG13S30 and SG13S42 at the 13q12-13
locus. Or, the presence of the alleles T, G, G, G and A at SG13S99,
SG13S25, SG13S106, SG13S30 and SG13S42, respectively (the B5
haplotype), is diagnostic of susceptibility to myocardial
infarction or stroke Or, a haplotype associated with a
susceptibility to myocardial infarction or stroke comprises markers
SG13S25, SG13S106, SG13S30 and SG13S42 at the 13q12-13 locus. Or,
the presence of the alleles G, G, G and A at SG13S25, SG13S106,
SG13S30 and SG13S42, respectively (the B4 haplotype), is diagnostic
of susceptibility to myocardial infarction or stroke. Or, a
haplotype associated with a susceptibility to myocardial infarction
or stroke comprises markers SG13S25, SG13S106, SG13S30 and SG13S32
at the 13q 12-13 locus. Or, the presence of the alleles G, G, G and
A at SG13S25, SG13S106, SG13S30 and SG13S32, respectively (the Bs4
haplotype), is diagnostic of susceptibility to myocardial
infarction or stroke. In such embodiments just described, patients
who are under consideration for treatment with compounds of any of
Formula (G), Formula (G-I), or Formula (G-II), or drug combinations
described herein that include compounds of any of Formula (G),
Formula (G-I), or Formula (G-II), may be screened for potential
responsiveness to treatment with compounds of any of Formula (G),
Formula (G-I), or Formula (G-II), based on such haplotypes.
[0447] By way of example only, a haplotype associated with a
susceptibility to myocardial infarction or stroke comprises markers
SG13S99, SG13S25, SG13S114, SG13S89 and SG13S32 at the 13q12-13
locus. Or, the presence of the alleles T, G, T, G and A at SG13S99,
SG13S25, SG13S114, SG13S89 and SG13S32, respectively (the AS
haplotype), is diagnostic of susceptibility to myocardial
infarction or stroke. Or, a haplotype associated with a
susceptibility to myocardial infarction or stroke comprises markers
SG13S25, SG13S114, SG13S89 and SG13S32 at the 13q12-13 locus. Or,
the presence of the alleles G, T, G and A at SG13S25, SG13S114,
SG13S89 and SG13S32, respectively (the A4 haplotype), is diagnostic
of susceptibility to myocardial infarction or stroke. In such
embodiments just described, patients who are under consideration
for treatment with compounds of any of Formula (G), Formula (G-I),
or Formula (G-II), or drug combinations described herein that
include compounds of any of Formula (G), Formula (G-I), or Formula
(G-II), may be screened for potential responsiveness to treatment
with compounds of any of Formula (G), Formula (G-I), or Formula
(G-II), based on such haplotypes.
[0448] Detecting haplotypes can be accomplished by methods known in
the art for detecting sequences at polymorphic sites, and therefore
patients may be selected using genotype selection of FLAP, 5-LO or
other leukotriene pathway gene polymorphisms. The presence or
absence of a leukotriene pathway gene polymorphism or haplotype can
be determined by various methods, including, for example, using
enzymatic amplification, restriction fragment length polymorphism
analysis, nucleic acid sequencing, electrophoretic analysis of
nucleic acid from the individual, or any combination thereof. In
certain embodiments, determination of a SNP or haplotype may
identify patients who will respond to, or gain benefit from,
treatment with compounds of any of Formula (G), Formula (G-I), or
Formula (G-II). By way of example, methods of diagnosing a
susceptibility to myocardial infarction or stroke in an individual,
comprises determining the presence or absence of certain single
nucleotide polymorphisms (SNPs) or of certain haplotypes, wherein
the presence of the SNP or the haplotype is diagnostic of
susceptibility to myocardial infarction or stroke.
[0449] Phenotype Analysis: Biomarkers
[0450] Patients who are under consideration for treatment with
compounds of any of Formula (G), Formula (G-I), or Formula (G-II),
or drug combinations described herein that include compounds of any
of Formula (G), Formula (G-I), or Formula (G-II), may be screened
for potential responsiveness to treatment based on
leukotriene-driven inflammatory biomarker phenotypes. Patient
screening based on leukotriene-driven inflammatory biomarker
phenotypes may be used as an alternative to, or it may be
complimentary with, patient screening by leukotriene pathway gene
haplotype detection. The term "biomarker" as used herein refers to
a characteristic which can be measured and evaluated as an
indicator of normal biological processes, pathological processes,
or pharmacological responses to therapeutic intervention. Thus a
biomarker may be any substance, structure or process which can be
measured in the body, or its products, and which may influence or
predict the incidence of outcome or disease. Biomarkers may be
classified into markers of exposure, effect, and susceptibility.
Biomarkers can be physiologic endpoints, by way of example blood
pressure, or they can be analytical endpoints, by way of example,
blood glucose, or cholesterol concentrations. Techniques, used to
monitor and/or measure biomarkers include, but are not limited to,
NMR, LC-MS, LC-MS/MS, GC-MS, GC-MS/MS, HPLC-MS, HPLC-MS/MS, FT-MS,
FT-MS/MS, ICP-MS, ICP-MS/MS, peptide/protein sequencing, nucleic
acid sequencing, electrophoresis techniques, immuno-assays,
immuno-blotting, in-situ hybridization, fluorescence in-situ
hybridization, PCR, radio-immuno assays, and enzyme-immuno assays.
Single nucleotide polymorphisms (SNPs) have also been useful for
the identification of biomarkers for propensity to certain diseases
and also susceptibility or responsiveness to drugs such as
chemotherapeutic agents and antiviral agents. These techniques, or
any combination thereof, may be used to screen patients for
leukotriene-dependent or leukotriene mediated diseases or
conditions, wherein such patients may be beneficially treated with
compounds of any of Formula (G), Formula (G-I), or Formula (G-II),
or drug combinations described herein that include compounds of any
of Formula (G), Formula (G-I), or Formula (G-II).
[0451] By way of example only, patients may be selected for
treatment with compounds of any of Formula (G), Formula (G-I), or
Formula (G-II), or drug combinations described herein that include
compounds of any of Formula (G), Formula (G-I), or Formula (G-II),
by screening for enhanced inflammatory blood biomarkers such as,
but not limited to, stimulated LTB.sub.4, LTC.sub.4, LTE.sub.4,
myeloperoxidase (MPO), eosinophil peroxidase (EPO), C-reactive
protein (CRP), soluble intracellular adhesion molecule (sICAM),
monocyte chemoattractant protein (MCP-1), monocyte inflammatory
protein (MIP-1.alpha.), interleukin-6 (IL-6), the TH2 T cell
activators interleukin 4 (IL-4), and 13 (IL-13) and other
inflammatory cytokines. In certain embodiments, patients with
inflammatory respiratory diseases, including but not limited to,
asthma and COPD, or with cardiovascular diseases, are selected as
those most likely to be responsive to leukotriene synthesis
inhibition using compounds of any of Formula (G), Formula (G-I), or
Formula (G-II), by using a panel of leukotriene driven inflammatory
biomarkers.
[0452] Phenotype Analysis: Functional Markers
[0453] Patients who are under consideration for treatment with
compounds of any of Formula (G), Formula (G-I), or Formula (G-II),
or drug combinations described herein that include compounds of any
of Formula (G), Formula (G-I), or Formula (G-II), may be screened
for response to known modulators of the leukotriene pathway.
Patient screening by evaluation of functional markers as indicators
of a patient's response to known modulators of the leukotriene
pathway may be used as an alternative to, or it may be
complimentary with, patient screening by leukotriene pathway gene
haplotype detection (genotype analysis) and/or
monitoring/measurement of leukotriene-driven inflammatory biomarker
phenotypes. Functional markers may include, but are not limited to,
any physical characteristics associated with a leukotriene
dependent condition or disease, or knowledge of current or past
drug treatment regimens.
[0454] By way of example only, the evaluation of lung volume and/or
function may be used as a functional marker for
leukotriene-dependent or leukotriene mediated diseases or
conditions, such as respiratory diseases. Lung function tests may
be used to screen patients, with such leukotriene-dependent or
leukotriene mediated diseases or conditions, for treatment using
compounds of any of Formula (G), Formula (G-I), or Formula (G-II),
or pharmaceutical compostitons or medicaments which include
compounds of any of Formula (G), Formula (G-I), or Formula (G-II).
Such tests include, but are not limited to, evaluation of lung
volumes and capacities, such as tidal volume, inspiratory reserve
volume, expiratory reserve volume, residual volume, inspiratory
capacity, functional residual capacity, vital capacity, total lung
capacity, respiratory minute volume, alveolar ventilation, timed
vital capacity, and ventilatory capacity. Method of measurement of
lung volumes and capacities include, but are not limited to,
maximum expiratory flow volume curve, forced expiratory volume in 1
sec. (FEV1), peak expiratory flow rate. In addition, other lung
function tests used as functional markers for patient evaluation
described herein include, but are not limited to, respiratory
muscle power, maximum inspiratory pressure, maximum expiratory
pressure, transdiaphragmatic pressure, distribution of ventilation,
single breath nitrogen test, pulmonary nitrogen washout, and gas
transfer.
[0455] Additionally, the knowledge of a patients past or current
treatment regimen may be used as a functional marker to assist in
screening patients for treatment of leukotriene dependent
conditions or diseases using compounds of any of Formula (G),
Formula (G-I), or Formula (G-II), or pharmaceutical compositions or
medicaments which include compounds of any of Formula (G), Formula
(G-I), or Formula (G-II). By way of example only, such treatment
regimens may include past or current treatment using zileuton
(Zyflo.TM.), montelukast (Singulair.TM.), pranlukast (Onon.TM.),
zafirlukast (Accolate.TM.)
[0456] Also, patients who are under consideration for treatment
with compounds of any of Formula (G), Formula (G-I), or Formula
(G-II), or drug combinations described herein that include
compounds of any of Formula (G), Formula (G-I), or Formula (G-II),
may be screened for functional markers which include, but are not
limited to, reduced eosinophil and/or basophil, and/or neutrophil,
and/or monocyte and/or dendritic cell and/or lymphocyte
recruitment, decreased mucosal secretion, decreased mucosal edema,
and/or increased bronchodilation.
[0457] Methods for the identification of a patient in need of
treatment for leukotriene-dependent or leukotriene mediated
conditions or diseases, and exemplary, non-limiting treatment
methods are shown in FIG. 12, FIG. 13 and FIG. 14, wherein a
patient sample is analyzed and the information obtained is used to
identify possible treatment methods. It is expected that one
skilled in the art will use this information in conjunction with
other patient information, including, but not limited to age,
weight, sex, diet, and medical condition, to choose a treatment
method. It is also expected that each piece of information will be
given a particular weight in the decision process. In certain
embodiments, the information obtained from the diagnostic methods
described above and any other patient information, including, but
not limited to age, weight, sex, diet, and medical condition, are
incorporated into an algorithm used to elucidate a tretment method,
wherein each piece of information will be given a particular weight
in the decision process.
[0458] In certain embodiments a patient sample is analyzed for
leukotriene gene haplotypes, by way of example only, FLAP
haplotypes, and the information obtained identifies a patient in
need of treatment using various treatment methods. Such treatment
methods include, but are not limited to, administering a
therapeutic effective amount of a compound of any of Formula (G),
Formula (G-I), or Formula (G-II), or pharmaceutical composition or
medicament which includes a compound of any of Formula (G), Formula
(G-I), or Formula (G-II), administering a therapeutic effective
amount of a compound of any of Formula (G), Formula (G-I), or
Formula (G-II), or pharmaceutical composition or medicament which
includes a compound of any of Formula (G), Formula (G-I), or
Formula (G-II), in combination with a therapeutic effective amount
of a leukotriene receptor antagonist (by way of example,
CysLT.sub.1/CysLT.sub.2 antagonist or CysLT.sub.1 antagonist), or
administering a therapeutic effective amount of a compound of any
of Formula (G), Formula (G-I), or Formula (G-II), or pharmaceutical
composition or medicament which includes a compound of any of
Formula (G), Formula (G-I), or Formula (G-II), in combination with
a therapeutic effective amount of another anti-inflammatory agent.
In other embodiments a patient sample is analyzed for leukotriene
gene haplotypes, by way of example only, FLAP haplotypes, and/or
phenotype biomarkers, and/or phenotype functional marker responses
to leukotriene modifying agents. The patient may then be treated
using various treatment methods. Such treatment methods include,
but are not limited to, administering a therapeutic effective
amount of a compound of any of Formula (G), Formula (G-I), or
Formula (G-II), or pharmaceutical composition or medicament which
includes a compound of any of Formula (G), Formula (G-I), or
Formula (G-II), administering a therapeutic effective amount of a
compound of any of Formula (G), Formula (G-I), or Formula (G-II),
or pharmaceutical composition or medicament which includes a
compound of any of Formula (G), Formula (G-I), or Formula (G-II),
in combination with a therapeutic effective amount of a leukotriene
receptor antagonist (by way of example, CysLT.sub.1/CysLT.sub.2
antagonist or CysLT.sub.1 antagonist), or administering a
therapeutic effective amount of a compound of any of Formula (G),
Formula (G-I), or Formula (G-II), or pharmaceutical composition or
medicament which includes a compound of any of Formula (G), Formula
(G-I), or Formula (G-II), in combination with a therapeutic
effective amount of another anti-inflammatory agent. In still other
embodiments a patient sample is analyzed for leukotriene gene
haplotypes, by way of example only, FLAP haplotypes, and phenotype
biomarkers, and phenotype functional marker responses to
leukotriene modifying agents. The patient may then be treated using
various treatment methods. Such treatment methods include, but are
not limited to, administering a therapeutic effective amount of a
FLAP inhibitor, or pharmaceutical composition or medicament which
includes a FLAP inhibitor, administering a therapeutic effective
amount of a FLAP inhibitor, or pharmaceutical composition or
medicament which includes a FLAP inhibitor, in combination with a
therapeutic effective amount of a leukotriene receptor antagonist
(by way of example, CysLT.sub.1/CysLT.sub.2 antagonist or
CysLT.sub.1 antagonist), or administering a therapeutic effective
amount of a FLAP inhibitor, or pharmaceutical composition or
medicament which includes a FLAP inhibitor, in combination with a
therapeutic effective amount of another anti-inflammatory
agent.

conditions shown in Scheme A is described for the synthesis of
3-[3-tert-butylsulfanyl-1-[4-(6-methoxy-pyridin-3-yl)-benzyl]-5-(pyridin--
2-ylmethoxy)-1H-indol-2-yl]-2,2-dimethyl-propionic acid (Compound
2-19).

[0495] A mixture of 4-acetamidophenol (Sigma-Aldrich; 73.6 g),
2-chloromethylpyridine hydrochloride (80 g) and cesium carbonate
(320 g) in DMF (1 L) was stirred at 70.degree. C. for 2 days. The
mixture was cooled, poured into water (2 L) and extracted with
EtOAC (.times.6). The organic layers were washed with brine, dried
(MgSO.sub.4) and filtered to give a tan solid (A-1, 114 g) which
was used as such in the next step.
Step 2: 4-(Pyridin-2-ylmethoxy)-phenylamine hydrochloride
[0496] A-1 (114 g) was dissolved in EtOH (1 L) and to this was
added KOH (50 g) in water (200 mL). The solution was heated to

3-[3-tert-Butylsulfanyl-5-(pyridin-2-ylmethoxy)-1H-indol-2-yl]-2,2--
dimethyl-propionic acid ethyl ester (A-4; 20.0 g, 45.4 mmol) was
dissolved in DMF (150 mL) and cooled to -10.degree. C. under
N.sub.2. Sodium hydride (60% dispersion in mineral oil; 2.0 g, 50.0
mmol) was added portionwise, and the reaction was stirred at
-10.degree. C. for 45 minutes until the foam had disappeared. To
this dark brown-reddish solution was added methanesulfonic acid
4-(6-methoxy-pyridin-3-yl)-benzyl ester (Int-72; 16.0 g, 54.5 mmol)
in DMF dropwise. The reaction was then stirred at -10.degree. C.
for 1 hour and allowed to warm to room temperature slowly. After 16
hours, LCMS confirmed the formation of the product. The reaction
was quenched with saturated NH.sub.4Cl and diluted with methyl
tert-butyl ether (MTBE) and water. The aqueous phase was extracted
twice with MTBE. The combined organic layers were dried over
MgSO.sub.4, filtered, and concentrated, and the crude product was
purified by column chromatography to give the desired product
(A-5).
Step 6:
3-[3-tert-Butylsulfanyl-1-[4-(6-methoxy-pyridin-3-yl)-benzyl]-5-(-
pyridin-2-ylmethoxy)-1H-indol-2-yl]-2,2-dimethyl-propionic acid
[0500] A-5 (21.5 g, 33.7 mmol) was dissolved in THF (100 mL) and
MeOH (100 mL) and stirred until it became a clear solution. 3N LiOH
aqueous solution (56 mL, 168.5 mmol) was added and the reaction was
refluxed at 80.degree. C. for 2 hours. LCMS confirmed the formation
of the product, so the reaction was cooled to room temperature and
partitioned between EtOAc and water. The pH of the aqueous solution
was adjusted to pH 1 with 10% HCl, and the aqueous phase was
extracted three times with EtOAc. The combined organic layers were
washed with water, dried over MgSO.sub.4, filtered, and
concentrated to give the desired free acid (A-6).

FLAP Binding Assays
[0555] A non-limiting example of such a FLAP binding assay is as
follows:
Packed human polymorphonuclear cell pellets (1.8.times.109 cells)
(Biological Speciality Corporation) were resuspended, lysed and
100,000g membranes prepared as described (Charleson et al. Mol.
Pharmacol, 41, 873-879, 1992). 100,000.times.g pelleted membranes
were resuspended in Tris-Tween assay buffer (100 mM Tris HCl pH
7.4, 140 mM NaCl, 2 mM EDTA, 0.5 mM DTT, 5% glycerol, 0.05% Tween
20) to yield a protein concentration of 50-100 ug/mL. 10 uL
membrane suspension was added to 96 well Millipore plate, 78 .mu.L
Tris-Tween buffer, 10 .mu.L .sup.3H MK886 or .sup.3H
3-[5-(pyrid-2-ylmethoxy)-3-tert-butylthio-1-benzyl-indol-2-yl]-2,2-dimeth-
ylpropionic acid (or .sup.125I MK591 derivative Eggler et al, J.
Labelled Compounds and Radiopharmaceuticals, 1994, vXXXIV, 1147))
to 30,000 cpm, 2 .mu.L inhibitor and incubated for 30 minutes at
room temperature. 100 .mu.L ice-cold washed buffer was added to the
incubation mixture. Plates were then filtered and washed 3.times.
with 200 .mu.L ice cold Tris-Tween buffer, scintillation bottoms
sealed, 100 .mu.L scintillant added, shaken for 15 minutes then
counted in a TopCount. Specific binding was determined as defined
as total radioactive binding minus non-specific binding in the
presence of 10 .mu.M MK886. IC.sub.50s were determined using
Graphpad prism analysis of drug titration curves.

Human Blood LTB.sub.4 inhibition Assay
[0556] A non-limiting example of such a human blood LTB.sub.4
inhibition assay is as follows:
Blood was drawn from consenting human volunteers into heparinized
tubes and 125 .mu.L aliquots added to wells containing 2.5 .mu.L
50% DMSO (vehicle) or 2.5 .mu.L drug in 50% DMSO. Samples were
incubated for 15 minutes at 37.degree. C. 2 .mu.L calcium ionophore
A23817 (from a 50 mM DMSO stock diluted just prior to the assay in
Hanks balanced salt solution (Invitrogen)) to 1.25 mM) was added,
solutions mixed and incubated for 30 minutes at 37.degree. C.
Samples were centrifuged at 1,000 rpm (.about.200.times.g) for 10
minutes at 4.degree. C., plasma removed and a 1:100 dilution
assayed for LTB.sub.4 concentration using ELISA (Assay Designs).
Drug concentrations to achieve 50% inhibition (IC50's) of vehicle
LTB.sub.4 were determined by nonlinear regression (Graphpad Prism)
of % inhibition versus log drug concentration.
Example 12
Rat peritoneal Inflammation and Edema Assay
[0557] A non-limiting example of such a rat peritoneal inflammation
and edema assay is as follows:
[0558] The in vivo efficacy of leukotriene biosynthesis inhibitors
was assessed using a rat model of peritoneal inflammation. Male
Sprague-Dawley rats (weighing 200-300 grams) received a single
intraperitoneal (i.p.) injection of 3 mL saline containing zymosan
(5 mg/mL) followed immediately by an intravenous (i.v.) injection
of Evans blue dye (2 mL of 1.5% solution). Compounds were
administered orally (3 mL/kg in 0.5% methylcellulose vehicle) 2 to
4 hours prior to zymosan injection. One to two hours after zymosan
injection, rats were euthanized, and the peritoneal cavity was
flushed with 10 mL phosphate buffered saline solution (PBS). The
resulting fluid was centrifuged at 1,200 rpm for 10 minutes.
Vascular edema was assesses by quantifying the amount of Evans blue
dye in the supernatant using a spectrophotometer (Absorbance 610
nm). LTB.sub.4 and cysteinyl leukotriene concentrations in the
supernatant were determined by ELISA. Drug concentrations to
achieve 50% inhibition of plasma leakage (Evans blue dye) and
inhibition of peritoneal LTB.sub.4 and cysteinyl leukotrienes could
be calculated by nonlinear regression (Graphpad Prism) of %
inhibition versus log drug concentration.,

Human Leukocyte Inhibition Assay
[0559] A non-limiting example of a human leukocyte inhibition assay
is as follows:
Blood was drawn from consenting human volunteers into heparanized
tubes and 3% dextran, 0.9% saline equal volume added. After
sedimentation of red blood cells a hypotonic lysis of remaining red
blood cells was performed and leukocytes sedimented at 1000 rpm.
The pellet was resuspended at 1.25.times.10.sup.5 cells/mL and
aliquoted into wells containing 2.5 .mu.L 20% DMSO (vehicle) or 2.5
.mu.L drug in 20% DMSO. Samples were incubated for 5 minutes at
37.degree. C. and 2 .mu.L calcium ionophore A23817 (from a 50 mM
DMSO stock diluted just prior to the assay in Hanks balanced salt
solution (Invitrogen)) to 1.25 mM) was added, solutions mixed and
incubated for 30 minutes at 37.degree. C. Samples were centrifuged
at 1,000 rpm (.about.200.times.g) for 10 minutes at 4.degree. C.,
plasma removed and a 1:4 dilution assayed for LTB.sub.4
concentration using ELISA (Assay Designs). Drug concentrations to
achieve 50% inhibition (IC50's) of vehicle LTB.sub.4 were
determined by nonlinear regression (Graphpad Prism) of % inhibition
versus log drug concentration. The compounds presented in Tables
1-4 had assays of 1 nM to 5 .mu.M with this assay.
