Indazole derivatives as JNK inhibitors and compositions and methods related thereto

1. FIELD OF THE INVENTION

[0002] This invention is generally directed to indazole derivatives useful as Jun N-terminal kinase (JNK) inhibitors, compositions comprising the indazole derivatives and methods for their use.

2. BACKGROUND OF THE INVENTION

[0003] The Jun N-terminal kinase (JNK) pathway is activated by exposure of cells to environmental stress or by treatment of cells with pro-inflammatory cytokines. Targets of the JNK pathway include the transcription factors c-jun and ATF2 (Whitmarsh A. J., and Davis R. J. J. Mol. Med. 74:589-607, 1996). These transcription factors are members of the basic leucine zipper (bZIP) group that bind as homo- and hetero-dimeric complexes to AP-1 and AP-1-like sites in the promoters of many genes (Karin M., Liu Z. G. and Zandi E. Curr. Opin. Cell Biol. 9:240-246, 1997). JNK binds to the N-terminal region of c-jun and ATF-2 and phosphorylates two sites within the activation domain of each transcription factor (Hibi M., Lin A., Smeal T, Minden A., Karin M. Genes Dev. 7:2135-2148, 1993; Mohit A. A., Martin M. H., and Miller C. A. Neuron 14:67-75, 1995). Three JNK enzymes have been identified as products of distinct genes (Hibi et al, supra; Mohit et al., supra). Ten different isoforms of JNK have been identified. These represent alternatively spliced forms of three different genes: JNK1, JNK2 and JNK3. JNK1 and 2 are ubiquitously expressed in human tissues, whereas JNK3 is selectively expressed in the brain, heart and testis (Dong C., Yang D., Wysk M., Whitmarsh A., Davis R., Flavell R. Science 270:1-4, 1998). Gene transcripts are alternatively spliced to produce four-JNK1 isoforms, four-JNK2 isoforms and two-JNK3 isoforms. JNK1 and 2 are expressed widely in mammalian tissues, whereas JNK3 is expressed almost exclusively in the brain. Selectivity of JNK signaling is achieved via specific interactions of JNK pathway components and by use of scaffold proteins that selectively bind multiple components of the signaling cascade. JIP-1 (JNK-interacting protein-1) selectively binds the MAPK module, MLK→NKK2→JNK. It has no binding affinity for a variety of other MAPK cascade enzymes. Different scaffold proteins are likely to exist for other MAPK signaling cascades to preserve substrate specificity.

[0004] JNKs are activated by dual phosphorylation on Thr-183 and Tyr-185. JNKK1 (also known as MKK 4) and JNKK2 (MKK7), two MAPKK level enzymes, can mediate JNK activation in cells (Lin A., Minden A., Martinetto H., Claret F. -Z., Lange-Carter C., Mercurio F., Johnson G. L., and Karin M. Science 268:286-289, 1995; Toumier C., Whitmarsh A. J., Cavanagh J., Barrett T., and Davis R. J. Proc. Nat. Acad. Sci. USA 94:7337-7342, 1997). JNKK2 specifically phosphorylates JNK, whereas JNKK1 can also phosphorylate and activate p38. Both JNKK1 and JNKK2 are widely expressed in mammalian tissues. JNKK1 and JNKK2 are activated by the MAPKKK enzymes, MEKK1 and 2 (Lange-Carter C. A., Pleiman C. M., Gardner A. M., Blumer K. J., and Johnson G. L. Science 260:315-319, 1993; Yan M., Dai J. C., Deak J. C., Kyriakis J. M., Zon L. I., Woodgett J. R., and Templeton D. J. Nature 372:798-781, 1994). Both MEKK1 and MEKK2 are widely expressed in mammalian tissues. Activation of the JNK pathway has been documented in a number of disease settings, providing the rationale for targeting this pathway for drug discovery. In addition, molecular genetic approaches have validated the pathogenic role of this pathway in several diseases. For example, autoimmune and inflammatory diseases arise from the over-activation of the immune system. Activated immune cells express many genes encoding inflammatory molecules, including cytokines, growth factors, cell surface receptors, cell adhesion molecules and degradative enzymes. Many of these genes are regulated by the JNK pathway, through activation of the transcription factors AP-1 and ATF-2, including TNFα, IL-2, E-selectin and matrix metalloproteinases such as collagenase-1 (Manning A.M. and Mercurio F. Exp. Opin Invest. Drugs 6: 555-567, 1997). Monocytes, tissue macrophages and tissue mast cells are key sources of TNFα production. The JNK pathway regulates TNFα production in bacterial lipopolysaccharide-stimulated macrophages, and in mast cells stimulated through the FceRII receptor (Swantek J. L., Cobb M. H., Geppert T. D. Mol. Cell. Biol. 17:6274-6282, 1997; Ishizuka T., Tereda N., Gerwins P., Hamelmann E., Oshiba A., Fanger G. R., Johnson G. L., and Gelfland E. W. Proc. Nat. Acad. Sci. USA 94:6358-6363, 1997). Inhibition of JNK activation effectively modulates TNFα secretion from these cells. The JNK pathway therefore regulates production of this key pro-inflammatory cytokine. Matrix metalloproteinases (MMPs) promote cartilage and bone erosion in rheumatoid arthritis, and generalized tissue destruction in other autoimmune diseases. Inducible expression of MMPs, including MMP-3 and MMP-9, type II and IV collagenases, are regulated via activation of the JNK pathway and AP-1 (Gum R., Wang H., Lengyel E., Juarez J., and Boyd D). Oncogene 14:1481-1493, 1997). In human rheumatoid synoviocytes activated with TNFα, IL-1, or Fas ligand the JNK pathway is activated (Han Z., Boyle D. L., Aupperle K. R., Bennett B., Manning A. M., Firestein G. S. J. Pharm. Exp. Therap. 291:1-7, 1999; Okamoto K., Fujisawa K., Hasunuma T., Kobata T., Sumida T., and Nishioka K. Arth & Rheum 40: 919-26, 1997). Inhibition of JNK activation results in decreased AP-1 activation and collagenase-1 expression (Han et al., supra). The JNK pathway therefore regulates MMP expression in cells involved in rheumatoid arthritis.

[0005] Inappropriate activation of T lymphocytes initiates and perpetuates many autoimmune diseases, including asthma, inflammatory bowel disease and multiple sclerosis. The JNK pathway is activated in T cells by antigen stimulation and CD28 receptor co-stimulation and regulates production of the growth factor IL-2 and cellular proliferation (Su B., Jacinto E., Hibi M., Kallunki T., Karin M., Ben—Neriah Y. Cell 77:727-736, 1994; Faris M., Kokot N., Lee L., and Nel A. E. J. Biol. Chem. 271:27366-27373, 1996). Peripheral T cells from mice genetically deficient in JNKK1 show decreased proliferation and IL-2 production after CD28 co-stimulation and PMA/Ca2+ ionophore activation, providing important validation for the role of the JNK pathway in these cells (Nishina H., Bachmann M., Oliveria-dos-Santos A. J., et al. J. Exp. Med. 186: 941-953, 1997). It is known that T cells activated by antigen receptor stimulation in the absence of accessory cell-derived co-stimulatory signals lose the capacity to synthesize IL-2, a state called clonal anergy. This is an important process by which auto—Reactive T cell populations are eliminated from the peripheral circulation. Of note, anergic T cells fail to activate the JNK pathway in response to CD3- and CD28—Receptor co-stimulation, even though expression of the JNK enzymes is unchanged (Li W., Whaley C. D., Mondino A., and Mueller D. L. Science 271: 1272-1276, 1996). Recently, the examination of JNK-deficient mice revealed that the JNK pathway plays a key role in T cell activation and differentiation to T helper 1 and 2 cell types. JNK1 or JNK2 knockout mice develop normally and are phenotypically unremarkable. Activated naïve CD4+ T cells from these mice fail to produce IL-2 and do not proliferate well (Sabapathy, K, Hu, Y, Kallunki, T, Schreiber, M, David, J- P, Jochum, W, Wagner, E, Karin, M. Curr Biol 9:116-125, 1999). It is possible to induce T cell differentiation in T cells from these mice, generating Th1 cells (producers of IFN-g and TNFβ) and Th2 effector cells (producers of IL-4, IL-5, IL-6, IL-10 and IL-13). Deletion of either JNK1 or JNK2 in mice resulted in a selective defect in the ability of Th1 effector cells to express IFNg. This suggests that JNK1 and JNK2 do not have redundant functions in T cells and that they play different roles in the control of cell growth, differentiation and death. The JNK pathway therefore, is an important point for regulation of T cell responses to antigen.

[0006] Cardiovascular disease (“CVD”) accounts for nearly one quarter of total annual deaths worldwide. Vascular disorders such as atherosclerosis and restenosis result from dysregulated growth of the vessel wall, restricting blood flow to vital organs. The JNK pathway is activated by atherogenic stimuli and regulates local cytokine and growth factor production in vascular cells (Yang D D, Conze D, Whitmarsh A J, et al, Immunity, 9:575, 1998). In addition, alterations in blood flow, hemodynamic forces and blood volume lead to JNK activation in vascular endothelium, leading to AP-1 activation and pro-atherosclerotic gene expression (Aspenstrom P., Lindberg U., and Hall A. Curr. Biol. 6:70-77, 1996). Ischemia and ischemia coupled with reperfusion in the heart, kidney or brain result in cell death and scar formation, which can ultimately lead to congestive heart failure, renal failure or cerebral dysfunction. In organ transplantation, reperfusion of previously ischemic donor organs results in acute leukocyte-mediated tissue injury and delay of graft function. The JNK pathway is activated by ischemia and reperfusion (Li Y., Shyy J., Li S., Lee J., Su B., Karin M., Chien S Mol. Cell. Biol. 16:5947-5954, 1996), leading to the activation of JNK—Responsive genes and leukocyte-mediated tissue damage. In a number of different settings JNK activation can be either pro- or anti-apoptotic. JNK activation is correlated with enhanced apoptosis in cardiac tissues following ischemia and reperfusion (Pombo C M, Bonventre J V, Avruch J, Woodgett J R, Kyriakis J. M, Force T. J. Biol. Chem. 269:26546-26551, 1994).

[0007] Cancer is characterized by uncontrolled growth, proliferation and migration of cells. Cancer is the second leading cause of death with 500,000 deaths and an estimated 1.3 million new cases in the United States in 1996. The role of signal transduction pathways contributing to cell transformation and cancer is a generally accepted concept. The JNK pathway leading to AP-1 appears to play a critical role in cancer. Expression of c-jun is altered in early lung cancer and may mediate growth factor signaling in non-small cell lung cancer (Yin T., Sandhu G., Wolfgang C. D., Burrier A., Webb R. L., Rigel D. F. Hai T., and Whelan J. J. Biol. Chem. 272:19943-19950, 1997). Indeed, over-expression of c-jun in cells results in transformation, and blocking c-jun activity inhibits MCF-7 colony formation (Szabo E., Riffe M., Steinberg S. M., Birrer M. J., Linnoila R. I. Cancer Res. 56:305-315, 1996). DNA-damaging agents, ionizing radiation and tumor necrosis factor activate the JNK pathway. In addition to regulating c-jun production and activity, JNK activation can regulate phosphorylation of p53, and thus can modulate cell cycle progression (Chen T. K., Smith L. M., Gebhardt D. K., Birrer M. J., Brown P. H. Mol. Carcinogenesis 15:215-226, 1996). The oncogene BCR-Ab1, associated with t(9,22) Philadelphia chromosome translocation of chronic myelogenous leukemia, activates JNK and leads to transformation of hematopoietic cells (Milne D. M., Campbell L. E., Campbell D. G., Meek D. W. J. Biol. Chem. 270:5511-5518, 1995). Selective inhibition of JNK activation by a naturally occurring JNK inhibitory protein, called JIP-1, blocks cellular transformation caused by BCR-Ab1 expression (Raitano A. B., Halpern J. R., Hambuch T. M., Sawyers C. L. Proc. Nat. Acad. Sci USA 92:11746-11750, 1995). Thus, JNK inhibitors may block transformation and tumor cell growth.

[0079] The compounds of this invention may generally be made by organic synthesis techniques known to those skilled in the art, as well as by the following general techniques and by the procedures set forth in the Examples. To that end, the compounds of this invention may be made according to the following Reaction Schemes 1 through 7 (it should be noted that, in the following reaction schemes, hydrogen atoms are sometimes not depicted and one skilled in organic chemistry would appreciate such accepted shorthand notation):

[0080] In Reaction Scheme 1, indazoles of this invention may be prepared by techniques well known to those skilled in the art of organic synthesis. Starting from an appropriately 5-substituted indazole, the 3-position may be activated for substitution by use of a suitable dihalogen (X2). If necessary, a protecting group is then added to the nitrogen at the 1-position (N-1) to give 1. The halogen may be displaced by an appropriately activated A—R1 moiety to give 2; see, e.g., Reaction Schemes 2 and 5. Alternatively, an appropriately substituted phenyl ketone may be cyclized to give indazole 2 see, e.g., Reaction Schemes 3 and 4. The G moiety may then be left unchanged, displaced or transformed into the desired R2; see, e.g., Reaction Schemes 3 through 6. Deprotection of N-1 gives indazoles of structure (I).

[0081] Reaction Scheme 2 illustrates synthetic sequences that yield compounds containing various A moieties. Suitable starting materials are commercially available indazoles with the desired R2 or may be readily prepared, e.g., as in Reaction Schemes 5 and 6. The starting indazole is halogenated at the 3-position with a suitable reagent, e.g., Br2. It is then protected at N-1 with any suitable nitrogen protecting group to give 3. Suitable protecting groups include but are not limited to acetyl, methoxyethoxymethyl and tetrahydropyranyl. Indazoles, wherein A is a direct bond, may be produced from 3 by displacement of the halogen with an appropriately activated RI moiety. For example, in the presence of a suitable Pd(0) or Pd(II) catalyst, Rl-boronic acids may be coupled via a Suzuki reaction to give, after deprotection, compound (II). Analogously, compounds (IV) and (V) may be prepared from suitable alkene and alkyne precursors in the presence of an appropriate Pd(0) catalyst. The cis isomer of indazole (IV) may also be prepared by partial reduction of (V) by, e.g., hydrogenation over BaSO4 that has been treated with quinoline. Compound (m) may be prepared from (IV) via reduction, e.g., with hydrogen in the presence of Pd-C.

[0082] Reaction Scheme 3 illustrates several syntheses of compound (VI) wherein R1 is depicted as a substituted phenyl group for purposes of illustration only. In Scheme 3A, a phenyl ketone, appropriately substituted at Y and R2, serves as the starting material. When Y is an amino group, the starting material may be cyclized by exposure, first to HNO2 and then to a reducing agent, such as SnCl2, to give compound (VI). Alternatively, when Y is a leaving group such as halogen (e.g., F or Cl), heating the phenyl ketone in the presence of hydrazine effects cyclization to indazole (VI).

[0083] In Scheme 3B, halogenated indazole 3 may be coupled with a suitable substituted phenyl moiety and deprotected to give compound (VI), wherein A is a direct bond. By way of example, a phenyl boronic acid substituted with 0-4 R3 groups will react with a protected 3-bromo-1H-indazole in the presence of a Pd(II) catalyst to yield compound (VI).

[0084] Scheme 3C illustrates an alternative synthesis of compound (VI) from the 5-halo-phenyl ketone; this route allows introduction of R2 groups later in the sequence. 4-Bromo-aniline is acylated with a suitably activated A-R1 moiety, heated in the presence of an appropriate Lewis acid such as ZnCl2. For example, a suitably activated A-R, group is an acid halide such as carbonyl chloride. The resulting ketone 4 is cyclized as in Scheme 3A, and protected with appropriate groups at the N-1 position as in Scheme 2. The R2 group may be introduced via a Pd-catalyzed coupling as in Scheme 2, and the protecting group removed to yield compound (VI).

[0085] The synthesis of the embodiment wherein R2 is an amino carbonyl-containing group is shown by Reaction Scheme 4. In analogy to Scheme 3A, a suitably substituted 4-nitro-phenyl ketone may be cyclized, depending on Y, by exposure either to hydrazine or to HNO2 and a reducing agent. After protection of N-1, the nitro-group may be reduced by, e.g., hydrogenation over Pd-C, to give 7. The resulting amine may optionally be substituted with R4, by, e.g., reductive amination, using procedures well known to one skilled in the art of organic synthesis. Compound 8 is acylated with a suitable activated carbonyl moiety and deprotected to give compound (VII). Alternatively, 7 may be hydrolyzed to the 5-hydroxy compound, 9.

[0086] Reaction Scheme 5 illustrates a synthetic route for the further embodiment of (I) wherein R2 is a carboxamide. Commercially available 5-amino-i H-indazole is substituted with cyanide at the 5-position to give 10 by treatment with HNO2, followed, after neutralization to ca. pH 7, by treatment with a cyanide source, e.g., a mixture of CuCn and NaCN. Nitrile 10 may be activated at the 3-position, protected at N-i and subsequently substituted with an appropriate A-R1 moiety according to procedures of Scheme 2. The resulting compound, 12, may be hydrolyzed in aqueous acid to give carboxylate 13. Activation of 13 by a suitable method, followed by treatment with R5R4NH and deprotection gives the carboxamide, 14. Suitable activation methods include but are not limited to 1) conversion of the carboxylate to an acyl halide (e.g., chloride) and coupling in the presence of pyridine or a related base; and 2) use of a coupling agent suitable for amide bond formation (e.g., dicyclohexylcarbodiimide).

[0087] Reaction Scheme 6 illustrates the additional embodiment wherein R2 is a five-membered heterocyclic substituent. In Scheme 6A, nitrile 12 is deprotected at N-1 and converted to the tetrazole 15 by use of an electrophilic azide source (e.g., a trialkyl tin such as (Bu)3SnN3). Nitrile 12 may also be converted to the unsubstituted triazole 17 in four steps. The nitrile is first transformed to the carboxamide by exposure to aqueous base under oxidizing conditions (e.g., NaOH and H2O2). The N-1 protecting group is removed to give intermediate 16. The carboxamide is heated with DMF acetal and subsequently treated with hydrazine under acidic conditions to give the desired triazole.

[0088] Scheme 6B illustrates the synthesis of imidazole and substituted triazole derivatives at R2. Nitrile 12 is deprotected and converted to the imidate or thioimidate by heating in the appropriate alcohol or thiol under acidic conditions to give 18. Subsequent exposure to 1-amino-2,2-dimethoxyethane and gentle heating effects formation of imidazole 19. Alternatively, heating 18 with alkyl, aryl or heterocyclic hydrazides under basic conditions (e.g., in presence of a tertiary organoamine such as triethylamine) results in production of 3-substituted triazole 20.

[0089] Pyrazole derivatives maybe synthesized according to Scheme 6C. Nitrile 12 may be deprotected at N-1 to give starting material 21. Treatment of the latter nitrile with a suitable organometallic agent, e.g., methyl lithium, yields a methyl ketone intermediate. Subsequent treatment by heating with DMF acetal followed by exposure to hydrazine gives pyrazole 22.

[0090] Scheme 7 depicts alternative routes to 5-triazole derivatives of 1H-indazoles. In scheme 7A nitrile 11 is converted to triazole 23 under conditions similar to those employed in Scheme 6B. A suitable protecting group, e.g., trityl, is incorporated onto the free triazole nitrogen to give 24. A-R1 is then added to position-3 by a boronic acid or other suitable derivative. Finally, the triazole protecting group is removed under, e.g., acidic conditions, to give indazole 17.

[0091] In Scheme 7B, starting material 25 is prepared by activation of 13 as, e.g., an acid halide such as chloride. Subsequent reaction with a protected hydrazide followed by removal of protecting groups yields hydrazide 26. By way of example, when PG=acetyl and PG2=t-butyl-oxycarbonyl, the protecting groups are removed by sequential treatment with ammonia followed by acid, e.g., HCl. Indazole 26 is treated with an appropriate imidate to give 27 and converted to triazole 20 by heating in a polar solvent, e.g., DMF.

[0092] Pharmaceutically acceptable salts of compounds of structure (I) are also within the scope of this invention. To this end, the compound may generally be utilized as the free base. Alternatively, the compounds may be used in the form of acid addition salts. Acid addition salts of the free base amino compounds of the present invention may be prepared by methods well known in the art, and may be formed from organic and inorganic acids. Suitable organic acids include maleic, fumaric, benzoic, ascorbic, succinic, methanesulfonic, acetic, oxalic, propionic, tartaric, salicylic, citric, gluconic, lactic, mandelic, cinnamic, aspartic, stearic, palmitic, glycolic, glutamic, and benzenesulfonic acids. Suitable inorganic acids include hydrochloric, hydrobromic, sulfuric, phosphoric, and nitric acids. Thus, the term “pharmaceutically acceptable salt” of a compound of structure (I) is intended to encompass any and all acceptable salt forms.

[0093] Pharmaceutically acceptable salts of this invention may be formed by conventional and known techniques, such as by reacting a compound of this invention with a suitable acid as disclosed above. Such salts are typically formed in high yields at moderate temperatures, and often are prepared by merely isolating the compound from a suitable acidic wash in the final step of the synthesis. The salt-forming acid may dissolved in an appropriate organic solvent, or aqueous organic solvent, such as an alkanol, ketone or ester. On the other hand, if the compound of this invention is desired in the free base form, it may be isolated from a basic final wash step, according to known techniques. For example, a typical technique for preparing hydrochloride salt is to dissolve the free base in a suitable solvent, and dry the solution thoroughly, as over molecular sieves, before bubbling hydrogen chloride gas through it.

[0094] The compound of this invention may also exist in various isomeric forms, including configurational, geometric and conformational isomers, as well as existing in various tautomeric forms, particularly those that differ in the point of attachment of a hydrogen atom. As used herein, the term “isomer” is intended to encompass all isomeric forms of a compound, including tautomeric forms of the compound.

[0095] As used herein, the term “prodrug” refers to any derivative of indazoles of this invention that are metabolized or otherwise converted into an active form upon introduction into the body of an animal. Prodrugs are well known to those skilled in the art of pharmaceutical chemistry, and provide benefits such as increased adsorption and half-life. Prodrugs of this invention may be formed when, for example, hydroxy groups are esterified or alkylated, or when carboxyl groups are esterified. Those skilled in the art of drug delivery will readily appreciate that the pharmacokinetic properties of indazoles of this invention may be controlled by an appropriate choice of moieties to produce prodrug derivatives.

In certain embodiments, more than one compound of the invention is administered to a patient. Methods of administration include but are not limited to intradermal, intramuscular, intraperitoneal, intravenous, subcutaneous, epidural, oral, sublingual, intranasal, intracerebral, intravaginal, transdermal, rectally, by inhalation, or topically, particularly to the ears, nose, eyes, or skin. The preferred mode of administration is left to the discretion of the practitioner, and will depend in-part upon the site of the medical condition. In most instances, administration will result in the release of the compounds of the invention into the bloodstream.

[0127] In specific embodiments, it may be desirable to administer one or more compounds of the invention locally to the area in need of treatment.

In yet another embodiment, a controlled-Release system can be placed in proximity of the target of the compounds of the invention, e.g., the liver, thus requiring only a fraction of the systemic dose (see, e.g., Goodson, in Medical Applications of Controlled Release, supra, vol. 2, pp. 115-138 (1984)). Other controlled-Release systems discussed in the review by Langer, 1990, Science 249:1527-1533) may be used.

The term “vehicle” refers to a diluent, adjuvant, excipient, or carrier with which a compound of the invention is administered. Such pharmaceutical vehicles can be liquids, such as water and oils, including those of petroleum, animal, vegetable or synthetic origin, such as peanut oil, soybean oil, mineral oil, sesame oil and the like. The pharmaceutical vehicles can be saline, gum acacia, gelatin, starch paste, talc, keratin, colloidal silica, urea, and the like. In addition, auxiliary, stabilizing, thickening, lubricating and coloring agents may be used. When administered to a patient, the compounds of the invention and pharmaceutically acceptable vehicles are preferably sterile. Water is a preferred vehicle when the compound of the invention is administered intravenously. Saline solutions and aqueous dextrose and glycerol solutions can also be employed as liquid vehicles, particularly for injectable solutions. Suitable pharmaceutical vehicles also include excipients such as starch, glucose, lactose, sucrose, gelatin, malt, rice, flour, chalk, silica gel, sodium stearate, glycerol monostearate, talc, sodium chloride, dried skim milk, glycerol, propyleneglycol, water, ethanol and the like. The present compositions, if desired, can also contain minor amounts of wetting or emulsifying agents, or pH buffering agents The present compositions can take the form of solutions, suspensions, emulsion, tablets, pills, pellets, capsules, capsules containing liquids, powders, sustained-release formulations, suppositories, emulsions, aerosols, sprays, suspensions, or any other form suitable for use. In one embodiment, the pharmaceutically acceptable vehicle is a capsule (see e.g., U.S. Pat. No. 5,698,155). Other examples of suitable pharmaceutical vehicles are described in “Remington's Pharmaceutical Sciences” by E. W. Martin.

[0134] In a preferred embodiment, the compounds of the invention are formulated in accordance with routine procedures as a pharmaceutical composition adapted for intravenous administration to human beings. Typically, compounds of the invention for intravenous administration are solutions in sterile isotonic aqueous buffer. Where necessary, the compositions may also include a solubilizing agent. Compositions for intravenous administration may optionally include a local anesthetic such as lignocaine to ease pain at the site of the injection. Generally, the ingredients are supplied either separately or mixed together in unit dosage form, for example, as a dry lyophilized powder or water free concentrate in a hermetically sealed container such as an ampoule or sachette indicating the quantity of active agent. Where the compound of the invention is to be administered by infusion, it can be dispensed, for example, with an infusion bottle containing sterile pharmaceutical grade water or saline. Where the compound of the invention is administered by injection, an ampoule of sterile water for injection or saline can be provided so that the ingredients may be mixed prior to administration.

[0135] Compositions for oral delivery may be in the form of tablets, lozenges, aqueous or oily suspensions, granules, powders, emulsions, capsules, syrups, or elixirs, for example. Orally administered compositions may contain one or more optional agents, for example, sweetening agents such as fructose, aspartame or saccharin; flavoring agents such as peppermint, oil of wintergreen, or cherry; coloring agents; and preserving agents, to provide a pharmaceutically palatable preparation. Moreover, where in tablet or pill form, the compositions may be coated to delay disintegration and absorption in the gastrointestinal tract thereby providing a sustained action over an extended period of time. Selectively permeable membranes surrounding an osmotically active driving compound are also suitable for orally administered compounds of the invention. In these later platforms, fluid from the environment surrounding the capsule is imbibed by the driving compound, which swells to displace the agent or agent composition through an aperture. These delivery platforms can provide an essentially zero order delivery profile as opposed to the spiked profiles of immediate release formulations. A time delay material such as glycerol monostearate or glycerol stearate may also be used. Oral compositions can include standard vehicles such as mannitol, lactose, starch, magnesium stearate, sodium saccharine, cellulose, magnesium carbonate, etc. Such vehicles are preferably of pharmaceutical grade.

[0136] The dose of a compound of this invention to be administered to a patient, such as a human, is rather widely variable and subject to the judgment of the attending physician. The general range of effective administration rates of the compounds of this invention are from about 0.05 mg/day to about 250 mg/day, and typically from about 0.25 mg/day to 60 mg/day. Of course, it is often practical to administer the daily dose of compound in portions, at various hours of the day. However, in any given case, the amount of compound administered will depend on such factors as the solubility of the active component, the formulation used, subject condition (such as weight), and/or the route of administration.

[0137] Further, the effect of the compounds of this invention may be delayed or prolonged by proper formulation. For example, a slowly soluble pellet of the compound may be prepared and incorporated in a tablet or capsule. The technique may be improved by making pellets of several different dissolution rates and filling capsules with a mixture of the pellets. Tablets or capsules may be coated with a film which resists dissolution for a predictable period of time. Even the parenteral preparations may be made long-acting, by dissolving or suspending the compound in oily or emulsified vehicles which allow it to disperse only slowly in the serum.

[0138] The following examples are offered by way of illustration, not limitation. (To this end, it should be noted that one or more hydrogen atoms may be omitted from the drawn structures consistent with accepted shorthand notation of such organic compounds, and that one skilled in the art would readily appreciate their presence.)

The c-Jun phosphorylation is terminated by addition of 150 μL of 12.5% trichloroacetic acid. After 30 minutes, the precipitate is harvested onto a filter plate, diluted with 50 μL of the scintillation fluid and quantified by a counter. The IC50 values are calculated as the concentration of the test compound at which the c-Jun phosphorylation is reduced to 50% of the control value. Preferred compounds of the present invention have an IC50 value ranging 0.01-10 μM in this assay.

[1983] Jurkat T-Cell 11-2 Production Assay

[1984] Jurkat T cells (clone E6-1) are purchased from the American Tissue Culture Collection and maintained in growth media consisting of RPMI 1640 medium containing 2 mM L-glutamine (Mediatech), with 10% fetal bovine serum (Hyclone) and penicillin/streptomycin. All cells are cultured at 37° C. in 95% air and 5% CO2. Cells are plated at a density of 0.2×106 cells per well in 200 μL of media. Compound stock (20 mM) is diluted in growth media and added to each well as a 10× concentrated solution in a volume of 25 μL, mixed, and allowed to pre-incubate with cells for 30 minutes. The compound vehicle (dimethylsulfoxide) is maintained at a final concentration of 0.5% in all samples. After 30 minutes the cells are activated with PHA (phorbol myristate acetate; final concentration 50 μg/mL) and PHA (phytohemagglutinin; final concentration 2 μg/mL). PMA and PHA are added as a lOx concentrated solution made up in growth media and added in a volume of 25 μL per well. Cell plates are cultured for 10 hours. Cells are pelleted by centrifugation and the media removed and stored at −20° C. Media aliquots are analyzed by sandwich ELISA for the presence of IL-2 as per the manufacturers instructions (Endogen). The IC50 values are calculated as the concentration of the test compound at which the 11-2 production was reduced to 50% of the control value. Preferred compounds of the present invention have an IC50 value ranging 0.1-30 μM in this assay.

[1985] Rat in Vivo LPS-Induced TNF-α Production Assay

[1986] Male CD rats procured from Charles River Laboratories at 7 weeks of age were allowed to acclimate for one week prior to use. A lateral tail vein was cannulated percutaneously with a 22-gage over-the-needle catheter under brief isoflurane anesthesia. Rats were administered test compound either by intravenous injection via the tail vein catheter or oral gavage 15 to 180 min prior to injection of 0.05 mg/kg LPS (E. Coli 055:BS). Catheters were flushed with 2.5 mL/kg of normal injectable saline. Blood was collected via cardiac puncture 90 minutes after LPS challenge. Plasma was prepared using lithium heparin separation tubes and frozen at −80° C. until analyzed. TNF-(X levels were determined using a rat specific TNF-α ELISA kit (Biosource). The ED50 values are calculated as the dose of the test compound at which the TNF-A production is reduced to 50% of the control value. Preferred compounds of the present invention have an ED50 value ranging 1-30 mg/kg in this assay.
