Description
RELATED APPLICATION
[0001] This application claims the benefit of U.S. Provisional
application 62/008,012, filed on Jun. 5, 2014, the content of which
is incorporated by reference in its entirety.
TECHNICAL FIELD OF THE INVENTION
[0002] The present invention relates to quinoline compounds useful
as antagonists of P2X7. The invention also provides
pharmaceutically acceptable compositions comprising compounds of
the present invention and methods of using said compositions in the
treatment of various disorders.
BACKGROUND OF THE INVENTION
[0003] The P2X7 receptor is a ligand-gated ion channel that belongs
to the Purinergic Receptor Family. The receptor is expressed on
many cell types related to the immune and nervous systems. In the
nervous system P2X7 is expressed on microglia, oligodendrocytes and
astrocytes. Brief activation of the P2X7 receptor channel with its
endogenous ligand ATP leads to several downstream events including
the processing and release of the proinflammatory cytokine
IL1-.beta. from monocytes and macrophages. P2X7 activation also
plays an important role in regulating the glutamate release/uptake
in astrocytes.
[0004] P2X7 receptors are ionotropic receptors activated by ATP,
which may regulate neurotransmission in the CNS by activating
presynaptic and/or postsynaptic P2X7 receptors on central and
peripheral neurons and glia (Deuchars S. A. et al., J. Neurosci.
21:7143-7152, (2001), Kanjhan R. et al., J. Comp. Neurol. 407:11-32
(1997), Le K. T. et al., Neuroscience 83:177-190 (1998)).
Activation of the P2X7 receptor on cells of the immune system
(macrophages, mast cells and lymphocytes) leads to release of
interleukin-1.beta. (IL-1.beta.), giant cell formation,
degranulation, and L-selectin shedding. ATP is able to increase
local release and process of IL-1 in rats through a P2X7 receptor
mediated mechanism following lipopolysaccharide (LPS)
intraperitoneal injections (Griffiths et al., J. Immunology Vol.
154, pages 2821-2828 (1995); Solle et al., J. Biol. Chemistry, Vol.
276, pages 125-132, (2001)).
[0005] Antagonism of the P2X7 receptor is considered to be an
attractive therapeutic approach for the treatment of multiple
sclerosis and Alzheimer's disease, due to its significant role in
dampening the CNS inflammation and supporting neuroprotection.
SUMMARY OF THE INVENTION
[0006] It has now been found that compounds of this invention, and
pharmaceutically acceptable compositions thereof, are effective as
antagonists of P2X7. Such compounds have general formula I:
##STR00001##
or a pharmaceutically acceptable salt thereof, wherein each of Ring
A, Z, R.sup.1, R.sup.2, m, and n, is as defined and described in
embodiments herein.
[0007] Compounds of the present invention, and pharmaceutically
acceptable compositions thereof, are useful for treating a variety
of diseases, disorders or conditions, associated with P2X7
activity. Such diseases, disorders, or conditions include those
described herein.

phenoxazinyl, tetrahydroquinolinyl, tetrahydroisoquinolinyl, and
pyrido[2,3-b]-1,4-oxazin-3(4H)-one. A heteroaryl group is
optionally mono- or bicyclic. The term "heteroaryl" is used
interchangeably with the terms "heteroaryl ring", "heteroaryl
group", or "heteroaromatic", any of which terms include rings that
are optionally substituted. The term "heteroaralkyl" refers to an
alkyl group substituted by a heteroaryl, wherein the alkyl and
heteroaryl portions independently are optionally substituted.
[0021] As used herein, the terms "heterocycle", "heterocyclyl",
"heterocyclic radical", and "heterocyclic ring" are used
interchangeably and refer to a stable 5- to 7-membered monocyclic
or 7-10-membered bicyclic heterocyclic moiety that is either
saturated or partially unsaturated, and having, in addition to
carbon atoms, one or more, preferably one to four, heteroatoms, as
defined above. When used in reference to a ring atom of a
heterocycle, the term "nitrogen" includes a substituted nitrogen.
As an example, in a saturated or partially unsaturated ring having
0-3 heteroatoms selected from oxygen, sulfur or nitrogen, the
nitrogen is N (as in 3,4-dihydro-2H-pyrrolyl), NH (as in
pyrrolidinyl), or +NR (as in N-substituted pyrrolidinyl).
[0022] A heterocyclic ring can be attached to its pendant group at
any heteroatom or carbon atom that results in a stable structure
and any of the ring atoms can be optionally substituted. Examples
of such saturated or partially unsaturated heterocyclic radicals
include, without limitation, tetrahydrofuranyl, tetrahydropyranyl,
tetrahydrothiophenyl pyrrolidinyl, piperidinyl, pyrrolinyl,
morpholinyl, tetrahydroquinolinyl, tetrahydroisoquinolinyl,
decahydroquinolinyl, oxazolidinyl, piperazinyl, dioxanyl,
dioxolanyl, diazepinyl, oxazepinyl, thiazepinyl, morpholinyl, and
quinuclidinyl. The terms "heterocycle", "heterocyclyl",
"heterocyclyl ring", "heterocyclic group", "heterocyclic moiety",
and "heterocyclic radical", are used interchangeably herein, and
also include groups in which a heterocyclyl ring is fused to one or
more aryl, heteroaryl, or cycloaliphatic rings, such as indolinyl,
3H-indolyl, chromanyl, phenanthridinyl, or tetrahydroquinolinyl,
where the radical or point of attachment is on the heterocyclyl
ring. A heterocyclyl group is optionally mono- or bicyclic. The
term "heterocyclylalkyl" refers to an alkyl group substituted by a
heterocyclyl, wherein the alkyl and heterocyclyl portions
independently are optionally substituted.
[0023] As used herein, the term "partially unsaturated" refers to a
ring moiety that includes at least one double or triple bond. The
term "partially unsaturated" is intended to encompass rings having
multiple sites of unsaturation, but is not intended to include aryl
or heteroaryl moieties, as herein defined.
[0024] As described herein, certain compounds of the invention
contain "optionally substituted" moieties. In general, the term
"substituted", whether preceded by the term "optionally" or not,
means that one or more hydrogens of the designated moiety are
replaced with a suitable substituent. "Substituted" applies to one
or more hydrogens that are either explicit or implicit from the
structure (e.g.,
##STR00002##
refers to at least
##STR00003##
and
##STR00004##
refers to at least
##STR00005##
Unless otherwise indicated, an "optionally substituted" group has a
suitable substituent at each substitutable position of the group,
and when more than one position in any given structure is
substituted with more than one substituent selected from a
specified group, the substituent is either the same or different at
every position. Combinations of substituents envisioned by this
invention are preferably those that result in the formation of
stable or chemically feasible compounds. The term "stable", as used
herein, refers to compounds that are not substantially altered when
subjected to conditions to allow for their production, detection,
and, in certain embodiments, their recovery, purification, and use
for one or more of the purposes disclosed herein.
[0025] Suitable monovalent substituents on a substitutable carbon

[0047] As used herein, the term "pharmaceutically acceptable salt"
refers to those salts which are, within the scope of sound medical
judgment, suitable for use in contact with the tissues of humans
and lower animals without undue toxicity, irritation, allergic
response and the like, and are commensurate with a reasonable
benefit/risk ratio. Pharmaceutically acceptable salts are well
known in the art. For example, S. M. Berge et al., describe
pharmaceutically acceptable salts in detail in J. Pharmaceutical
Sciences, 1977, 66, 1-19, incorporated herein by reference.
Pharmaceutically acceptable salts of the compounds of this
invention include those derived from suitable inorganic and organic
acids and bases. Examples of pharmaceutically acceptable, nontoxic
acid addition salts are salts of an amino group formed with
inorganic acids such as hydrochloric acid, hydrobromic acid,
phosphoric acid, sulfuric acid and perchloric acid or with organic
acids such as acetic acid, oxalic acid, maleic acid, tartaric acid,
citric acid, succinic acid or malonic acid or by using other
methods used in the art such as ion exchange. Other
pharmaceutically acceptable salts include adipate, alginate,
ascorbate, aspartate, benzenesulfonate, benzoate, bisulfate,
borate, butyrate, camphorate, camphorsulfonate, citrate,
cyclopentanepropionate, digluconate, dodecylsulfate,
ethanesulfonate, formate, fumarate, glucoheptonate,
glycerophosphate, gluconate, hemisulfate, heptanoate, hexanoate,
hydroiodide, 2-hydroxy-ethanesulfonate, lactobionate, lactate,
laurate, lauryl sulfate, malate, maleate, malonate,
methanesulfonate, 2-naphthalenesulfonate, nicotinate, nitrate,
oleate, oxalate, palmitate, pamoate, pectinate, persulfate,
3-phenylpropionate, phosphate, pivalate, propionate, stearate,
succinate, sulfate, tartrate, thiocyanate, p-toluenesulfonate,
undecanoate, valerate salts, and the like.
[0048] Salts derived from appropriate bases include alkali metal,
alkaline earth metal, ammonium and N.sup.+(C.sub.1-4alkyl).sub.4
salts. Representative alkali or alkaline earth metal salts include
sodium, lithium, potassium, calcium, magnesium, and the like.
Further pharmaceutically acceptable salts include, when
appropriate, nontoxic ammonium, quaternary ammonium, and amine
cations formed using counterions such as halide, hydroxide,
carboxylate, sulfate, phosphate, nitrate, loweralkyl sulfonate and
aryl sulfonate.
[0049] Unless otherwise stated, structures depicted herein are also
meant to include all isomeric (e.g., enantiomeric, diastereomeric,
tautomers, and geometric (or conformational)) forms of the
structure; for example, the R and S configurations for each
asymmetric center, Z and E double bond isomers, and Z and E
conformational isomers. Therefore, single stereochemical isomers as
well as enantiomeric, diastereomeric, and geometric (or
conformational) mixtures of the present compounds are within the
scope of the invention. Unless otherwise stated, all tautomeric
forms of the compounds of the invention are within the scope of the
invention.
[0050] Additionally, unless otherwise stated, structures depicted
herein are also meant to include compounds that differ only in the
presence of one or more isotopically enriched atoms. For example,
compounds having the present structures including the replacement
of hydrogen by deuterium or tritium, or the replacement of a carbon
by a .sup.13C- or .sup.14C-enriched carbon are within the scope of
this invention. In some embodiments, the group comprises one or
more deuterium atoms.
[0051] There is furthermore intended that a compound of the formula
I includes isotope-labeled forms thereof. An isotope-labeled form
of a compound of the formula I is identical to this compound apart
from the fact that one or more atoms of the compound have been
replaced by an atom or atoms having an atomic mass or mass number
which differs from the atomic mass or mass number of the atom which
usually occurs naturally. Examples of isotopes which are readily
commercially available and which can be incorporated into a
compound of the formula I by well-known methods include isotopes of
hydrogen, carbon, nitrogen, oxygen, phos-phorus, fluo-rine and
chlorine, for example .sup.2H, .sup.3H, .sup.13C, .sup.14C,
.sup.15N, .sup.18O, .sup.17O, .sup.31P, .sup.32P, .sup.35S,
.sup.18F and .sup.36CI, respectively. A compound of the formula I,
a prodrug, thereof or a pharmaceutically acceptable salt of either
which contains one or more of the above-mentioned isotopes and/or
other isotopes of other atoms is intended to be part of the present
invention. An isotope-labeled compound of the formula I can be used
in a number of beneficial ways. For example, an isotope-labeled
compound of the formula I into which, for example, a radioisotope,
such as .sup.3H or .sup.14C, has been incorporated, is suitable for
medicament and/or substrate tissue distribution assays. These
radioisotopes, i.e. tritium (.sup.3H) and carbon-14 (.sup.14C), are
particularly preferred owing to simple preparation and excellent
detectability. Incorporation of heavier isotopes, for example
deuterium (.sup.2H), into a compound of the formula I has
therapeutic advantages owing to the higher metabolic stability of
this isotope-labeled compound. Higher metabolic stability
translates directly into an increased in vivo half-life or lower
dosages, which under most circumstances would represent a preferred
embodiment of the present invention. An isotope-labeled compound of
the formula I can usually be prepared by carrying out the
procedures disclosed in the synthesis schemes and the related
description, in the example part and in the preparation part in the
present text, replacing a non-isotope-labeled reactant by a readily
available isotope-labeled reactant. Compounds of the invention may
be substituted by .sup.18F, for use as PET imaging agents.
[0052] Deuterium (.sup.2H) can also be incorporated into a compound
of the formula I for the purpose in order to manipulate the
oxidative metabolism of the compound by way of the primary kinetic
isotope effect. The primary kinetic isotope effect is a change of
the rate for a chemical reaction that results from exchange of
isotopic nuclei, which in turn is caused by the change in ground
state energies necessary for covalent bond formation after this
isotopic exchange. Exchange of a heavier isotope usually results in
a lowering of the ground state energy for a chemical bond and thus
causes a reduction in the rate in rate-limiting bond breakage. If
the bond breakage occurs in or in the vicinity of a saddle-point
region along the coordinate of a multi-product reaction, the
product distribution ratios can be altered substantially. For
explanation: if deuterium is bonded to a carbon atom at a
non-exchangeable position, rate differences of k.sub.M/k.sub.D=2-7
are typical. If this rate difference is successfully applied to a
corn-pound of the formula I that is susceptible to oxidation, the
profile of this compound in vivo can be drastically modified and
result in improved pharmacokinetic properties.
[0053] When discovering and developing therapeutic agents, the
person skilled in the art is able to optimize pharmacokinetic
parameters while retaining desirable in vitro properties. It is
reasonable to assume that many compounds with poor pharmacokinetic
profiles are susceptible to oxidative metabolism. In vitro liver
microsomal assays currently available provide valuable information
on the course of oxidative metabolism of this type, which in turn
permits the rational design of deuterated compounds of the formula
I with improved stability through resistance to such oxidative
metabolism. Significant improvements in the pharmacokinetic
profiles of compounds of the formula I are thereby obtained, and
can be expressed quantitatively in terms of increases in the in
vivo half-life (t/2), concen-tra-tion at maximum therapeutic effect
(C.sub.max), area under the dose response curve (AUC), and F; and
in terms of reduced clearance, dose and materials costs.
[0054] The following is intended to illustrate the above: a
compound of the formula I which has multiple potential sites of
attack for oxidative metabolism, for example benzylic hydrogen
atoms and hydrogen atoms bonded to a nitrogen atom, is prepared as
a series of analogues in which various combinations of hydrogen
atoms are replaced by deuterium atoms, so that some, most or all of
these hydrogen atoms have been replaced by deuterium atoms.
Half-life determinations enable favorable and accurate
determination of the extent of the extent to which the improvement
in resistance to oxidative metabolism has improved. In this way, it
is determined that the half-life of the parent compound can be
extended by up to 100% as the result of deuterium-hydrogen exchange
of this type.
[0055] Deuterium-hydrogen exchange in a compound of the formula I
can also be used to achieve a favorable modification of the
metabolite spectrum of the starting compound in order to diminish
or eliminate undesired toxic metabolites. For example, if a toxic
metabolite arises through oxidative carbon-hydrogen (C--H) bond
cleavage, it can reasonably be assumed that the deuterated analogue
will greatly diminish or eliminate production of the unwanted
metabolite, even if the particular oxidation is not a
rate-determining step. Further information on the state of the art
with respect to deuterium-hydrogen exchange may be found, for
example in Hanzlik et al., J. Org. Chem. 55, 3992-3997, 1990,

[0209] The method of the invention can be performed either in-vitro
or in-vivo. The susceptibility of a particular cell to treatment
with the compounds according to the invention can be particularly
determined by in-vitro tests, whether in the course of research or
clinical application. Typically, a culture of the cell is combined
with a compound according to the invention at various
concentrations for a period of time which is sufficient to allow
the active agents to antagonize P2X7 activity, usually between
about one hour and one week. In-vitro treatment can be carried out
using cultivated cells from a biopsy sample or cell line.
[0210] The host or subject can belong to any mammalian species, for
example a primate species, particularly humans; rodents, including
mice, rats and hamsters; rabbits; horses, cows, dogs, cats, etc.
Animal models are of interest for experimental investigations,
providing a model for treatment of human disease.
[0211] For identification of a signal transduction pathway and for
detection of interactions between various signal transduction
pathways, suitable models or model systems have been developed, for
example cell culture models and models of transgenic animals. For
the determination of certain stages in the signal transduction
cascade, interacting compounds can be utilized in order to modulate
the signal. The compounds according to the invention can also be
used as reagents for testing P2X7-dependent signal transduction
pathways in animals and/or cell culture models or in the clinical
diseases mentioned in this application.
[0212] The use according to the previous paragraphs of the
specification may be either performed in-vitro or in-vivo models.
The modulation can be monitored by the techniques described in the
course of the present specification. In certain embodiments, the
in-vitro use is preferably applied to samples of humans suffering
from P2X7-related disorders. Testing of several specific compounds
and/or derivatives thereof makes the selection of that active
ingredient possible that is best suited for the treatment of the
human subject. The in-vivo dose rate of the chosen derivative is
advantageously pre-adjusted to the P2X7 susceptibility and/or
severity of disease of the respective subject with regard to the
in-vitro data. Therefore, the therapeutic efficacy is remarkably
enhanced. Moreover, the subsequent teaching of the present
specification concerning the use of the compounds according to
formula (I) and its derivatives for the production of a medicament
for the prophylactic or therapeutic treatment and/or monitoring is
considered as valid and applicable without restrictions to the use
of the compound for the antagonism of P2X7 activity if
expedient.
[0213] The invention also relates to the use of compounds according
to formula (I) and/or physiologically acceptable salts thereof for
the prophylactic or therapeutic treatment and/or monitoring of
diseases that are caused, mediated and/or propagated by P2X7
activity. Furthermore, the invention relates to the use of
compounds according to formula (I) and/or physiologically
acceptable salts thereof for the production of a medicament for the
prophylactic or therapeutic treatment and/or monitoring of diseases
that are caused, mediated and/or propagated by P2X7 activity. In
certain embodiments, the invention provides the use of a compound
according to formula I or physiologically acceptable salts thereof,
for the production of a medicament for the prophylactic or
therapeutic treatment of a P2X7-mediated disorder.
[0214] Compounds of formula (I) and/or a physiologically acceptable
salt thereof can furthermore be employed as intermediate for the
preparation of further medicament active ingredients. The
medicament is preferably prepared in a non-chemical manner, e.g. by
combining the active ingredient with at least one solid, fluid
and/or semi-fluid carrier or excipient, and optionally in
conjunction with a single or more other active substances in an
appropriate dosage form.
[0215] The compounds of formula (I) according to the invention can
be administered before or following an onset of disease once or
several times acting as therapy. The aforementioned compounds and
medical products of the inventive use are particularly used for the
therapeutic treatment. A therapeutically relevant effect relieves
to some extent one or more symptoms of a disorder, or returns to
normality, either partially or completely, one or more
physiological or biochemical parameters associated with or
causative of a disease or pathological condition. Monitoring is
considered as a kind of treatment provided that the compounds are
administered in distinct intervals, e.g. in order to booster the
response and eradicate the pathogens and/or symptoms of the disease
completely. Either the identical compound or different compounds
can be applied. The methods of the invention can also be used to
reducing the likelihood of developing a disorder or even prevent
the initiation of disorders associated with P2X7 activity in
advance or to treat the arising and continuing symptoms.
[0216] In the meaning of the invention, prophylactic treatment is
advisable if the subject possesses any preconditions for the
aforementioned physiological or pathological conditions, such as a
familial disposition, a genetic defect, or a previously passed
disease.
[0217] The invention furthermore relates to a medicament comprising
at least one compound according to the invention and/or
pharmaceutically usable derivatives, salts, solvates and
stereoisomers thereof, including mixtures thereof in all ratios. In
certain embodiments, the invention relates to a medicament
comprising at least one compound according to the invention and/or
physiologically acceptable salts thereof.
[0218] A "medicament" in the meaning of the invention is any agent
in the field of medicine, which comprises one or more compounds of
formula (I) or preparations thereof (e.g. a pharmaceutical
composition or pharmaceutical formulation) and can be used in
prophylaxis, therapy, follow-up or aftercare of patients who suffer
from diseases, which are associated with P2X7 activity, in such a
way that a pathogenic modification of their overall condition or of
the condition of particular regions of the organism could establish
at least temporarily.
[0219] In another aspect, the invention provides for a kit
consisting of separate packs of an effective amount of a compound
according to the invention and/or pharmaceutically acceptable
salts, derivatives, solvates and stereoisomers thereof, including
mixtures thereof in all ratios, and optionally, an effective amount
of a further active ingredient. The kit comprises suitable
containers, such as boxes, individual bottles, bags or ampoules.
The kit may, for example, comprise separate ampoules, each
containing an effective amount of a compound according to the
invention and/or pharmaceutically acceptable salts, derivatives,
solvates and stereoisomers thereof, including mixtures thereof in
all ratios, and an effective amount of a further active ingredient
in dissolved or lyophilized form.
[0220] As used herein, the terms "treatment," "treat," and
"treating" refer to reversing, alleviating, delaying the onset of,
or inhibiting the progress of a disease or disorder, or one or more
symptoms thereof, as described herein. In some embodiments,
treatment is administered after one or more symptoms have
developed. In other embodiments, treatment is administered in the
absence of symptoms. For example, treatment is administered to a
susceptible individual prior to the onset of symptoms (e.g., in
light of a history of symptoms and/or in light of genetic or other
susceptibility factors). Treatment is also continued after symptoms
have resolved, for example to prevent or delay their
recurrence.
[0221] The compounds and compositions, according to the method of
the present invention, are administered using any amount and any
route of administration effective for treating or lessening the
severity of a disorder provided above. The exact amount required
will vary from subject to subject, depending on the species, age,
and general condition of the subject, the severity of the
infection, the particular agent, its mode of administration, and
the like. Compounds of the invention are preferably formulated in
dosage unit form for ease of administration and uniformity of
dosage. The expression "dosage unit form" as used herein refers to
a physically discrete unit of agent appropriate for the patient to
be treated. It will be understood, however, that the total daily
usage of the compounds and compositions of the present invention
will be decided by the attending physician within the scope of
sound medical judgment. The specific effective dose level for any
particular patient or organism will depend upon a variety of
factors including the disorder being treated and the severity of
the disorder; the activity of the specific compound employed; the
specific composition employed; the age, body weight, general
health, sex and diet of the patient; the time of administration,
route of administration, and rate of excretion of the specific
compound employed; the duration of the treatment; drugs used in
combination or coincidental with the specific compound employed,
and like factors well known in the medical arts.
[0222] Pharmaceutically acceptable compositions of this invention
can be administered to humans and other animals orally, rectally,
parenterally, intracisternally, intravaginally, intraperitoneally,
topically (as by powders, ointments, or drops), bucally, as an oral
or nasal spray, or the like, depending on the severity of the
infection being treated. In certain embodiments, the compounds of
the invention are administered orally or parenterally at dosage
levels of about 0.01 mg/kg to about 100 mg/kg and preferably from
about 1 mg/kg to about 50 mg/kg, of subject body weight per day,
one or more times a day, to obtain the desired therapeutic
effect.
[0223] Liquid dosage forms for oral administration include, but are
not limited to, pharmaceutically acceptable emulsions,
microemulsions, solutions, suspensions, syrups and elixirs. In
addition to the active compounds, the liquid dosage forms
optionally contain inert diluents commonly used in the art such as,
for example, water or other solvents, solubilizing agents and
emulsifiers such as ethyl alcohol, isopropyl alcohol, ethyl
carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate,
propylene glycol, 1,3-butylene glycol, dimethylformamide, oils (in
particular, cottonseed, groundnut, corn, germ, olive, castor, and
sesame oils), glycerol, tetrahydrofurfuryl alcohol, polyethylene
glycols and fatty acid esters of sorbitan, and mixtures thereof.
Besides inert diluents, the oral compositions can also include
adjuvants such as wetting agents, emulsifying and suspending
agents, sweetening, flavoring, and perfuming agents.
[0224] Injectable preparations, for example, sterile injectable
aqueous or oleaginous suspensions are formulated according to the
known art using suitable dispersing or wetting agents and
suspending agents. The sterile injectable preparation are also a
sterile injectable solution, suspension or emulsion in a nontoxic
parenterally acceptable diluent or solvent, for example, as a
solution in 1,3-butanediol. Among the acceptable vehicles and
solvents that may be employed are water, Ringer's solution, U.S.P.
and isotonic sodium chloride solution. In addition, sterile, fixed
oils are conventionally employed as a solvent or suspending medium.
For this purpose any bland fixed oil can be employed including
synthetic mono- or diglycerides. In addition, fatty acids such as
oleic acid are used in the preparation of injectables.
[0225] Injectable formulations can be sterilized, for example, by
filtration through a bacterial-retaining filter, or by
incorporating sterilizing agents in the form of sterile solid
compositions which can be dissolved or dispersed in sterile water
or other sterile injectable medium prior to use.
[0226] In order to prolong the effect of a compound of the present
invention, it is often desirable to slow the absorption of the
compound from subcutaneous or intramuscular injection. This is
accomplished by the use of a liquid suspension of crystalline or
amorphous material with poor water solubility. The rate of
absorption of the compound then depends upon its rate of
dissolution that, in turn, may depend upon crystal size and
crystalline form. Alternatively, delayed absorption of a
parenterally administered compound form is accomplished by
dissolving or suspending the compound in an oil vehicle. Injectable
depot forms are made by forming microencapsule matrices of the
compound in biodegradable polymers such as
polylactide-polyglycolide. Depending upon the ratio of compound to
polymer and the nature of the particular polymer employed, the rate
of compound release can be controlled. Examples of other
biodegradable polymers include poly(orthoesters) and
poly(anhydrides). Depot injectable formulations are also prepared
by entrapping the compound in liposomes or microemulsions that are
compatible with body tissues.
[0227] Compositions for rectal or vaginal administration are
preferably suppositories which can be prepared by mixing the
compounds of this invention with suitable non-irritating excipients
or carriers such as cocoa butter, polyethylene glycol or a
suppository wax which are solid at ambient temperature but liquid
at body temperature and therefore melt in the rectum or vaginal
cavity and release the active compound.
[0228] Solid dosage forms for oral administration include capsules,
tablets, pills, powders, and granules. In such solid dosage forms,
the active compound is mixed with at least one inert,
pharmaceutically acceptable excipient or carrier such as sodium
citrate or dicalcium phosphate and/or a) fillers or extenders such
as starches, lactose, sucrose, glucose, mannitol, and silicic acid,
b) binders such as, for example, carboxymethylcellulose, alginates,
gelatin, polyvinylpyrrolidinone, sucrose, and acacia, c) humectants
such as glycerol, d) disintegrating agents such as agar-agar,
calcium carbonate, potato or tapioca starch, alginic acid, certain
silicates, and sodium carbonate, e) solution retarding agents such
as paraffin, f) absorption accelerators such as quaternary ammonium
compounds, g) wetting agents such as, for example, cetyl alcohol
and glycerol monostearate, h) absorbents such as kaolin and
bentonite clay, and i) lubricants such as talc, calcium stearate,
magnesium stearate, solid polyethylene glycols, sodium lauryl
sulfate, and mixtures thereof. In the case of capsules, tablets and
pills, the dosage form also optionally comprises buffering
agents.
[0229] Solid compositions of a similar type are also employed as
fillers in soft and hard-filled gelatin capsules using such
excipients as lactose or milk sugar as well as high molecular
weight polyethylene glycols and the like. The solid dosage forms of
tablets, dragees, capsules, pills, and granules can be prepared
with coatings and shells such as enteric coatings and other
coatings well known in the pharmaceutical formulating art. They
optionally contain opacifying agents and can also be of a
composition that they release the active ingredient(s) only, or
preferentially, in a certain part of the intestinal tract,
optionally, in a delayed manner. Examples of embedding compositions
that can be used include polymeric substances and waxes. Solid
compositions of a similar type are also employed as fillers in soft
and hard-filled gelatin capsules using such excipients as lactose
or milk sugar as well as high molecular weight polethylene glycols
and the like.
[0230] The active compounds can also be in micro-encapsulated form
with one or more excipients as noted above. The solid dosage forms
of tablets, dragees, capsules, pills, and granules can be prepared
with coatings and shells such as enteric coatings, release
controlling coatings and other coatings well known in the
pharmaceutical formulating art. In such solid dosage forms the
active compound may be admixed with at least one inert diluent such
as sucrose, lactose or starch. Such dosage forms also comprise, as
is normal practice, additional substances other than inert
diluents, e.g., tableting lubricants and other tableting aids such
a magnesium stearate and microcrystalline cellulose. In the case of
capsules, tablets and pills, the dosage forms optionally also
comprise buffering agents. They optionally contain opacifying
agents and can also be of a composition that they release the
active ingredient(s) only, or preferentially, in a certain part of
the intestinal tract, optionally, in a delayed manner. Examples of
embedding compositions that can be used include polymeric
substances and waxes.
[0231] Dosage forms for topical or transdermal administration of a
compound of this invention include ointments, pastes, creams,
lotions, gels, powders, solutions, sprays, inhalants or patches.
The active component is admixed under sterile conditions with a
pharmaceutically acceptable carrier and any needed preservatives or
buffers as required. Ophthalmic formulation, ear drops, and eye
drops are also contemplated as being within the scope of this
invention. Additionally, the present invention contemplates the use
of transdermal patches, which have the added advantage of providing
controlled delivery of a compound to the body. Such dosage forms
can be made by dissolving or dispensing the compound in the proper
medium. Absorption enhancers can also be used to increase the flux
of the compound across the skin. The rate can be controlled by
either providing a rate controlling membrane or by dispersing the
compound in a polymer matrix or gel.
[0232] The compounds of the invention can also be utilized as
commercial research reagents for various medical research and
diagnostic uses. Such uses can include but are not limited to: use
as a calibration standard for quantifying the activities of
candidate P2X7 antagonists in a variety of functional assays; use
as blocking reagents in random compound screening, i.e. in looking
for new families of P2X7 receptor ligands, the compounds can be
used to block recovery of the presently claimed P2X7 compounds; use
in the co-crystallization with P2X7 receptor, i.e. the compounds of
the present invention will allow formation of crystals of the
compound bound to P2X7, enabling the determination of
receptor/compound structure by x-ray crystallography; other
research and diagnostic applications, etc.; use in assays as probes
for determining the expression of P2X7 on the surface of cells; and
developing assays for detecting compounds which bind to the same
site as the P2X7 binding ligands.
[0233] The compounds of formula (I), their salts, isomers,
tautomers, enantiomeric forms, diastereomers, racemates,
derivatives, prodrugs and/or metabolites are characterized by a
high specificity and stability, low manufacturing costs and
convenient handling. These features form the basis for a
reproducible action, wherein the lack of cross-reactivity is
included, and for a reliable and safe interaction with the target
structure.
[0234] The term "biological sample", as used herein, includes,
without limitation, cell cultures or extracts thereof; biopsied
material obtained from a mammal or extracts thereof; and blood,
saliva, urine, feces, semen, tears, or other body fluids or
extracts thereof.
[0235] Antagonism of P2X7 activity in a biological sample is useful
for a variety of purposes that are known to one of skill in the
art. Examples of such purposes include, but are not limited to,
blood transfusion, organ transplantation, biological specimen
storage, and biological assays.

Example 146
IL-1.beta. Release Assay
[0582] The activation of P2X7 by ATP leads to a fast transient
activation of cells resulting in influx of Ca.sup.2+ followed by
conversion of pro-IL-1.beta. to active IL-1.beta.. The functional
activity of P2X7 compounds was measured by the release of mature
IL-1.beta. in the culture medium of THP-1 cells, detected by
sandwich ELISA. Cells were maintained in complete growth medium
(RPMI 1640+10% HI-FCS+2 mM L-glutamine+1.times.PS). Every 3 days,
the medium was renewed by diluting the cells 1/3 to 1/4 as cell
density did not exceed 0.5 million cells per ml (seeding cell
density @1.times.10.sup.5/ml). THP-1 cells were harvested from the
flask in 50 ml by centrifugation for 3 min at 100 g. The cells were
resuspended to 2.times.10.sup.5 cells/ml in medium supplemented
with 0.5 .mu.M PMA and incubated. The cells were washed and
resuspended to 1.5.times.10.sup.5 cells/ml in medium complemented
with 10 ng/ml LPS, and the cells were primed for 4 h at 37.degree.
C., 5% CO.sub.2. After addition of 20 .mu.L of prediluted test
compounds, blank, standard and control reagents, cells were
incubated for a further 20 min at 37.degree. C. and stimulated with
0.8 mM BzATP for 30 minutes. The cells were centrifuged,
supernatant was collected and the presence of mature IL-1.beta. was
detected using Dual human IL-1b kit following manufacturer's
instruction. The tetrahydrobenzodiazepine analogs effectively
modulated the activity of P2X7 in the cells as measured by the
levels of pro-inflammatory cytokine IL-1.beta., which is released
by the activation of P2X7 receptor.
Pore Permeation Assay
[0583] Agonist-induced pore formation was determined by measuring
cellular uptake of YO PRO fluorescence dye in HEK293 transfected
with human P2X7 receptor. A HEK293 cell over expressing human P2X7
was harvested using HQTase reagent to detach the cells from T75 cm
flask. The harvested cells are centrifuged @1200 rpm for 5 min at
room temperature. The viability of cells was determined by Trypan
blue dye and the cells are plated @10,000 cell/well in 50 ul volume
in a 384W BD Poly lysine coated plate and incubated overnight at 37
C. After overnight incubation, the culture medium was replaced with
35 ul/well assay buffer (5 mM KCl, 0.1 mM CaCl2, 5 mM Glucose, 10
mM HEPES buffer pH7.4 containing 125 mM NaCl. The serial dilution
of compounds was performed using Bravo liquid handling instrument
and the compounds were added using Bravo to the cell assay plate
starting at 2.5 uM with three dilutions for 10 points. The positive
control inhibitor compound was added to column 23. The plate was
shaken slowly on a plate shaker for 10 seconds. The cells were
incubated with the compound for 20 minutes at room temperature.
After the incubation period, YO PRO dye (1 uM) along with BzATP (10
uM) were added to cells at 10 ul/well. The plate was centrifuged at
1000 rpm for 5 seconds and incubated at room temperature for 30
minutes. The uptake of YO PRO dye into the cells was measured using
Envision Fluorescence plate reader instrument (Perkin Elmer).
