Description: 6,5-FUSED BICYCLIC HETEROCYCLES FIELD OF THE INVENTION The invention provides 6,5-fused bicyclic compounds, pharmaceutical compositions thereof, and methods of making and using such compounds and compositions to inhibit the 15-lipoxygenase enzyme, and thus treat diseases with an inflammatory component. BACKGROUND OF THE INVENTION Hypercholesterolemia can induce monocytes to migrate into the arterial wall and mature into foam cells or tissue macrophages that accumulate fatty material, including cholesterol esters. For example, continued creation of foam cells thickens the inner lining of medium and large arteries, thereby forming atherosclerotic plaques or lesions containing cholesterol, smooth muscle cells, and connective tissue cells. Affected arteries lose elasticity and become narrowed or obstructed by the plaques. These events are the hallmark of the disease atherosclerosis. Furthermore, atherosclerotic plaques may collect calcium, become brittle, and even rupture, triggering the formation of a blood clot or thrombus capable of occluding an artery and causing a stroke or a heart attack. In addition to atherosclerosis, hypercholesterolemia plays a role in peripheral vascular diseases of small arteries, veins, and lymphatics. Thus, hypercholesterolemia may also affect the arms, legs, kidneys, and other vital organs in addition to the heart and brain. Cholesterol is transported in blood in particles called lipoproteins, such as low-density lipoproteins. Low-density lipoproteins also contain polyunsaturated fatty acids and are necessary for foam cell formation. Lipoxygenases are enzymes that catalyze the oxidation of polyunsaturated fatty acids and esters thereof, including those found in low-density lipoproteins. For example, the enzyme 15-lipoxygenase (15-LO) oxidizes esterified polyenoic fatty acids. 15-LO has been implicated in inflammatory disorders and in the origin and recruitment of foam cells. In addition to modifying lipoproteins involved in the formation of foam cells, 15-LO also mediates an inflammatory reaction in the atherosclerotic lesion. In human monocytes, 15-LO is induced by the cytokine IL-4. Inhibitors of 15-LO are therefore useful to prevent and treat diseases with an inflammatory component such as asthma, psoriasis, osteoarthritis, rheumatoid arthritis, colorectal cancer, and atherosclerosis. For example, it has been shown that treatment with an inhibitor of 15-LO suppressed atherogenesis, or the production of atheroma, a fatty degeneration of the arterial wall, in rabbits fed a high-fat diet. An object of this invention is to provide new 6,5-fused heterocycles that are potent inhibitors of 15-LO, and are thus useful for the treatment of diseases and disorders containing an inflammatory component.

Terms Certain terms used herein are defined below and by their usage throughout this disclosure. Alkyl groups include aliphatic (i.e., hydrocarbon radicals containing hydrogen and carbon atoms) with a free valence. Alkyl groups are understood to include straight chain and branched structures. Preferred alkyl groups have from 1 to 6 carbon atoms. Examples of typical alkyl groups include methyl, ethyl, propyl, isopropyl, butyl, n-butyl, isobutyl, t-butyl, pentyl, isopentyl, 2,3-dimethylpropyl, hexyl, 2,3-dimethyl hexyl, 1,1-dimethylpentyl, heptyl, and octyl. Cycloalkyl groups are C3-Cg cyclic structures, examples of which include cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, and cyclooctyl. Alkyl and cycloalkyl groups can be substituted with 1, 2, 3 or more substituents which are independently selected from halo (fluoro, chloro, bromo, or iodo), hydroxy, amino, alkoxy, alkylamino, dialkylamino, cycloalkyl, aryl, aryloxy, arylalkyloxy, heterocyclic radical, (heterocyclic radical)oxy, (amino)sulfonyl, N-acetyl, O-acetyl, C1-C4 thioalkyl, C1-C4 alkoxy, COORg, SO3Na, SO3H, SO2NH2, cyano, CH2NH2, acetyl, trifluoromethyl, and nitro. Specific examples include COOH, thiomethyl, methoxy, ethoxy, dimethylamino, ethylmefhylamino, diethylamino, and chloro.

Synthesis The invention compounds can be synthesized according to the following thirteen schemes, or variants thereof. Compounds of the present invention can be prepared using the general synthetic procedure shown in Scheme 1. The parent heterocycles can be purchased or synthesized by methods known to those skilled in the art (A.R. Katritzky and C.W. Rees, "Comprehensive Heterocyclic Chemistry, The Structures, Reactions, Synthesis, and Uses of Heterocyclic Compounds," Pergamon Press, NY, 1984;4(3.09):497-529). The free NH of the heterocycle is protected using the benzenesulfonyl group. The heterocycle of formula (1) is treated with benzenesulfonyl chloride and a base such as potassium or sodium hydroxide in a solvent such as methanol or ethanol to give the protected heterocycle of formula (2). The protected heterocycle of formula (2) is then deprotonated using a base such as n-BuLi in a solvent such as THF or diethyl ether, and the resulting organolithium species is then brominated with bromine to give a compound of formula (3). Lithium-halogen exchange with a base such as n-BuLi in a solvent such as THF or diethyl ether, followed by reaction with triisopropyl borate at temperatures ranging from -20°C to -78°C converts the compound of formula (3) to the boronic acid of formula (4). Suzuki coupling of the compound of formula (4) with the aryl bromide of formula (5) in the presence of tetrakis(triphenylphosphine)palladium (0) as catalyst and a base such as aqueous potassium carbonate in a solvent such as toluene gives the protected aryl heterocycle of formula (6). Reduction of the nitro group in the compound of formula (6) can be accomplished with Raney nickel and hydrogen gas in a solvent such as THF or DMF to give the amino compound of formula (7). The compound of formula (7) can be deprotected using HBr in glacial acetic acid to give the compound of formula (8). The compound of formula (8) can be reacted with a variety of compounds such as for example, sulfonyl chlorides, isothiocyanates, aryl halides, and acylchlorides to yield a variety of compounds of the present invention such as for example, sulfonamides, thioureas, N-aryl analogs, and reductive amination products. Alternatively, compounds of the present invention can be prepared as shown in Scheme 2. In Scheme 2, the bromo compound of formula (3) can be treated with hexamethylditin in a solvent such as benzene using a catalyst such as tetrakis(triphenylphosphine) palladium (0) at reflux temperatures to give the trimethyltin compound of formula (9). Stille coupling of the compound of formula (9) with the aryl bromide of formula (5) in the presence of tetrakis(triphenylphosphine) palladium (0) as catalyst in a solvent such as benzene gives the compound of formula (6) , which can be converted to compounds of the present invention as described for Scheme 1. In addition to the general methods of Schemes 1 and 2, which can be applied to the synthesis of all target compounds, there are other methods available for the synthesis of compounds of the present invention containing more specific ring systems. For the preparation of compounds of the present invention containing the 1 H-pyrrolo [2,3 -bjpyridine ring system, the method of Houlihan W.J., Parrino V.A., Uike Y., J. Org. Chem., 1981;46:4511-4515 can be employed as shown in Scheme 3. In Scheme 3, a key amide of formula (12) is prepared by reacting the acid of formula (10), which is commercially available, with oxalyl chloride in a solvent such as THF with a catalyst such as DMF to give the corresponding acid chloride, which is then coupled with 2-amino-3 -methyl pyridine of formula (11) in a solvent such as toluene using a base such as sodium or potassium carbonate at reflux temperatures to give the amide of formula (12). Treatment of the amide of formula (12) with 2 or 3 equivalents of a base such as n-BuLi or LDA in a solvent such as THF or diethyl ether at temperatures ranging from -20°C to +25°C gives the aryl heterocycle of formula (13), which can be converted to sulfonamides, thioureas, N-aryl analogs, and reductive amination products according to the procedure described above for Scheme 1 to provide compounds of the present invention containing the lH-pyrrolo[2,3-b]pyridine ring system. In addition, compounds of the present invention containing the 1 H-pyrrolo [3 ,2-b]pyridine ring system can be prepared using the method of Houlihan et al., by replacing 2-amino-3 -methyl pyridine of formula (11) with 3-amino-2-methyl pyridine of formula (28) to give a compound of formula (30) as shown in Scheme 7. A compound of formula (30) can be converted to sulfonamides, thioureas, N-aryl analogs, and reductive amination products according to the procedures described above for Scheme 1 to also provide compounds of the present invention containing the 1 H-pyrrolo [3 ,2-b]pyridine ring system. Alternatively, compounds of the present invention containing the 1H- pyrrolo[2,3-b]pyridine ring system can be prepared utilizing the method of Davis M ., Wakefield B.J., Wardell J.A., Tetrahedron, 1992;48:939-952 as shown in Scheme 4. In Scheme 4, deprotonation of 3-methylpyridine of formula (15) with a base such as LDA in a solvent such as THF or diethyl ether at temperatures ranging from -20°C to 15°C, followed by reaction of the corresponding anion with the commercially available benzonitrile of formula (14) gives an intermediate of formula (16), which on treatment with additional base cyclizes to give a compound of formula (13). The compound of formula (13) can be converted to sulfonamides, thioureas, N-aryl analogs, and reductive amination products according to the procedures described above for Scheme 1 to provide compounds of the present invention containing the lH-pyrrolo[2,3-b]pyridine ring system. In addition, compounds of the present invention containing the lH-pyrrolo[2,3-b]pyrazine ring system can be prepared using the method of Wakefield et al., by replacing 3-methylpyridine of formula (15) with 2-methylpyrazine of formula (31) to give a compound of formula (33) as shown in Scheme 8. A compound of formula (33) can be converted to sulfonamides, thioureas, N-aryl analogs, and reductive amination products according to the procedures described above for Scheme 1 to provide compounds of the present invention containing the lH-pyrrolo[2,3-b]pyrazine ring system. In addition, components of the present invention containing the 7H-pyrrolo[2,3-d]pyrimidine ring system can also be prepared using the method of Wakefield et al. by replacing 3-methylpyridine of formula (15) with 5-methylpyrimidine of formula (34) to give a compound of formula (36) as shown in Scheme 9. A compound of formula (36) can be converted to sulfonamides, thioureas, N-aryl analogs, and reductive amination products according to the procedures described above for Scheme 1 to provide compounds of the present invention containing the 7H-pyrrolo[2,3-d]pyrimidine ring system. For preparation of compounds of the present invention containing the lH-pyrrolo[2,3-c]pyridine ring system, the method of Fisher M.H., Schwartzkopf G., Jr., Hoff D.R., J. Med. Chem., 1972;15:1168-1171 can be employed as shown in Scheme 5. In Scheme 5, condensation of 3-nitropicoline of formula (17) with the commercially available aldehyde of formula (18) in the presence of a base such as piperidine in a solvent such as methanol or ethanol gives the styrylpyridine of formula (19). The styrylpyridine of formula (19) can be reductively cyclized using triethyl phosphite in a solvent such as benzene at reflux temperatures to yield a compound of formula (20). A compound of formula (20) can be converted to sulfonamides, thioureas, N-aryl analogs, and reductive amination products according to the procedures described above for Scheme 1 to provide compounds of the present invention containing the 1H- pyrrolo[2,3-c]pyridine ring system. For preparation of compounds of the present invention containing the lH-pyrrolo[3,2-c]pyridine ring system, another method of Fisher et al., Supra., 1972 can be employed as shown in Scheme 6. In Scheme 6, treatment of 4-chloro- 3 -methyl pyridine of formula (21) with an oxidizing agent such as m-chloroperoxybenzoic acid in a solvent such as dichloromethane or 1,2-dichloroethane at temperatures ranging from -10 C to 50°C gives the corresponding N-oxide of formula (22). The N-oxide of formula (22) is condensed with an aldehyde of formula (18) in the same manner as described in Scheme 5 for the conversion of a compound of formula (18) to a compound of formula (19) to give compound of formula (23). The compound of formula (23) is then reacted with hydrazine in a solvent such as methanol or ethanol to give the hydrazino derivative of formula (24). Reaction of the hydrazino derivative of formula (24) with aqueous sodium nitrite in an acid such as dilute (10%) hydrochloric acid at ambient temperatures gives the azido compound of formula (25), which is thermally decomposed in a solvent such as toluene at reflux temperatures to give the cyclized product formula (26). Reduction of the nitro group and deoxygenation of the pyridine-N-oxide in the cyclized product of formula (26) can be accomplished with Raney nickel and hydrogen gas in a solvent such as THF or DMF to give an amino compound of formula (27). An amino compound of formula (27) can be converted to sulfonamides, thioureas, N-aryl analogs, and reductive amination products according to the procedures described above for Scheme 1 to provide compounds of the present invention containing the 1H- pyrrolo[3,2-c]pyridine ring system. Compounds of the present invention containing the tetrahydroindole ring system can be prepared as shown in Schemes 10 and 11. In Scheme 10, the method of Hippeli C, Zimmer R., Reissig H.-U., Liebigs Ann. Chem., 1990:469-474 was employed. In this method, treatment of the commercially available ketone of formula (36) with a brominating agent such as N-bromosuccinimide in a solvent such as chloroform or carbon tetrachloride gives the bromo compound of formula (37). Treatment of the bromo compound of formula (37) with hydroxylamine in an aqueous methanol or ethanol solution gives the α-bromooxime of formula (38). Treatment of the α-bromooxime of formula (38) with the silyl enol ether of formula (39) and a base such as sodium carbonate in a solvent such as chloroform or dichloromethane at ambient temperatures gives the dihydro-l,2-oxazine of formula (40). Treatment of the dihydro-l,2-oxazine of formula (40) with molybdenum hexacarbonyl in acetonitrile at reflux temperatures results in deoxygenation and ring contraction to yield the tetrahydroindole of formula (41). The tetrahydroindole of formula (41) can be converted to sulfonamides, thioureas, N-aryl analogs, and reductive amination products according to the procedures described above for Scheme 1 to provide compounds of the present invention containing the tetrahydroindole ring system. Alternatively, compounds of the present invention containing the tetrahydroindole ring system can be prepared according to the method of Chiu P-K, Sammes M. P., Tetrahedron, 1988;44:3531-3538 as shown in Scheme 11. In Scheme 11, the requisite 1,4-diketone of formula (43) can be prepared by a Stork alkylation of the enamine of formula (42) with the bromo compound of formula (37) in a solvent such as dioxane at reflux temperatures. Paal-Knorr cyclization of the 1 ,4-diketone of formula (43) with liquid ammonia yields the desired compound of formula (41). The compound of formula (41) can be converted to sulfonamides, thioureas, N-aryl analogs, and reductive amination products according to the procedures described above for Scheme 1 to provide compounds of the present invention containing the tetrahydroindole ring system. Further compounds of the invention with a fused imidazole ring system, such as those of formula (A), can be made according to Scheme 12. Referring to Scheme 12, a diamino compound of formula (B) is condensed with an activated carboxylic acid compound of formula (C), such as an acid halide or an imidazolide, to give the desired imidazo compound of formula (D). This condensation is a two-step process in which an intermediate amide is formed which then dehydrates to give the imidazo compound of formula (D). These two steps can be done in one pot by refluxing with phosphorous oxychloride. The nitro group of the imidazo compound of formula (D) is reduced with an appropriate reagent such as Raney nickel with hydrogen gas or zinc in acetic acid to give the aniline compound of formula (E). The aniline compound of formula (E) can be converted to a compound of formula (A), wherein Q], Q2, Q3, Q4, R4, R5, and R a are as defined above for the compound of formula (A), according to procedures known in the arts of organic and medicinal chemistries for the N-substitution of imidiazole derivatives and the preparations of sulfonamides, thioureas, N-aryl analogs, reductive amination analogs, and the like described above for Scheme 1. An alternative to the above method for the preparation of a compound of formula (A) is illustrated in Scheme 13, wherein the imidazole ring is synthesized last.

BIOLOGICAL EXAMPLE 1 Rabbit Reticulocyte 15-LO Assay (hl5LO): The hl5LO assay measures inhibition of 15-LO catalyzed oxidation of linoleic acid to the hydroperoxy fatty acid 13-(S)HPODE, a conjugated diene. In the hl5LO assay, a test compound is incubated with 15-LO enzyme in the presence of the linoleic acid substrate. For example, 2 units (U) of rabbit reticulocyte 15-LO and 174 μM linoleic acid are incubated with a known amount of a test compound for 15 minutes at 4°C. The total reaction volume is 100 μL in phosphate buffered saline (PBS) containing 0.2% sodium cholate. The reaction is stopped with 100 μL of mobile phase and 10 μL of triethyl phosphite. 13 -(S)HPODE is reduced with triethyl phosphite to the more stable 13-hydroxyoctadecadienoate (13-HODE), which prevents artificial, nonenzymatic Hpidperoxidation and product breakdown in the sample. 13-HPODE is quantitated by comparing peak areas of individual samples with those from a standard curve generated using authentic 13-HODE. The test reaction is compared to a control reaction, which is identical to the test reaction except no test compound is present. Percent inhibition is calculated as the amount of 13-HODE produced in the test reaction divided by the amount of 13-HODE produced in the control reaction, expressed as a percent. 15-LO is obtained from phenylhydrazine-treated rabbits and purified according to the method of Rapoport (Rapoport et al., European Journal of Biochemistry, 1979;96:545-561). BIOLOGICAL EXAMPLE 2 Monocyte Recruitment: The recruitment or chemotaxis of monocytes is assayed by methods well- known to those skilled in the art. In particular, the method set forth in J. Clin. Invest., 1988;82:1853-1863, which is hereby incorporated by reference, can be used. BIOLOGICAL EXAMPLE 3 Collagen-Induced Arthritis in Mice: Type II collagen-induced arthritis (CIA) in mice is an experimental model of arthritis that has a number of pathologic, immunologic, and genetic features in common with rheumatoid arthritis. Type II collagen (CII) is a major component of joint cartilage. The disease CIA is induced by immunization of DBA/1 mice with 100 μg of type II collagen delivered intradermally in Freund's complete adjuvant. Disease susceptibility in this model is regulated by the Class II MHC gene locus, which is analogous to the known association of rheumatoid arthritis with the HLA-DR4 gene locus. A progressive and inflammatory arthritis develops in the majority of the immunized mice, characterized by paw width increases of up to 100%. A test compound is administered to mice in a range of amounts, such as 20, 60, 100, and 200 mg of test compound per kilogram of body weight per day. The duration of the test can be several weeks to a few months, such as 40, 60, or 80 days. A clinical scoring index is used to assess disease progression independently in each paw from Stage 1, erythema and edema (score=l), to Stage 2, joint distortion (score=2), to Stage 3, joint ankylosis (score=3). The disease CIA is variable in that it can affect one or all paws in an animal, resulting in a total possible score of 12 for each mouse. Histopathology of an arthritic joint reveals synovitis, pannus formation, and cartilage and bone erosions. All mouse strains that are susceptible to CIA are high antibody responders to type II collagen, and exhibit a marked cellular response to CII. BIOLOGICAL EXAMPLE 4 SCW-Induced Monoarticular Arthritis: Arthritis is induced as described by Schwab et al., Infection and Immunity, 1991;59:4436-4442, which is hereby incorporated by reference, with minor modifications. Rats receive 6 μg of sonicated streptococcal cell wall (SCW) particles (in 10 μL Dulbecco's PBS [DPBS]) by an intraarticular injection into the right tibiotalar joint on Day 0. On Day 21, the DTH is initiated with 100 μg of SCW (250 μL) administered IN. For oral compound studies, compounds are suspended in vehicle (0.5% hydroxypropyl-methylcellulose/0.2% Tween 80), sonicated, and administered twice daily (10 mL/kg volume) beginning 1 hour prior to reactivation with SCW. Compounds are administered in amounts between 10 and 500 mg/kg body weight/day, such as 20, 30, 60, 100, 200, and 300 mg/kg/day. Edema measurements are obtained by determining the baseline volumes of the sensitized hindpaw before reactivation on Day 21, and comparing them with volumes at subsequent time points such as Day 22, 23, 24, and 25. Paw volume is determined by mercury plethysmography. BIOLOGICAL EXAMPLE 5 Murine Ovalbumin-Induced Eosinophilia: The murine ovalbumin-induced eosinophilia assay measures the increase of eosinophil cells in lungs and upper airways in animals administered a compound of the present invention versus control animals administered only vehicle. In this assay, female C57BL/6 mice are obtained from the Jackson Laboratory (Bar Harbor, ME). All animals are given food and water ad libitum. Mice are sensitized with a single IP injection of ovalbumin (ONA) (Grade N, Sigma Chemical Company, St. Louis, MO) adsorbed to aluminum potassium sulfate (alum), (10 μg ONA + 9 mg alum in 200 μL saline), or vehicle control (9 mg alum in 200 μL saline) on Day 0. On Day 14, the mice are challenged with a 12-minute inhalation of an aerosol consisting of 1.5% ONA (weight/volume) in saline produced by a nebulizer (small particle generator, model SPAG-2; ICΝ Pharmaceuticals, Costa Mesa, CA). Groups of eight mice are dosed with oral vehicle (0.5% hydroxypropylmethylcellulose/0.25% polyoxethylene-sorbitan monooleate [TWEEΝ-80]), or a test compound at 10, 30, or 100 mg/kg in oral vehicle, 200 μL per mouse PO. Dosing is performed once per day starting on Day 7 or 13, and extending through Day 16. For determination of pulmonary eosinophilia, 3 days after the first OVA aerosol challenge (Day 17), the mice are anesthetized with an IP injection of anesthetic (Ketamine/Acepromazine/Xylazine), and the tracheae is exposed and cannulated. The lungs and upper airways are lavaged twice with 0.5 mL of cold PBS. A portion (200 μL) of the bronchoalveolar lavage (BAL) fluid is enumerated using a Coulter counter Model ZB1 (Coulter Electronics, Hialeah, FL). The remaining BAL fluid is then centrifuged at 300 x g for 5 minutes, and the cells are resuspended in 1 mL of Hank's Balanced salts (HBSS) (Gibco BRL) containing 0.5% fetal calf serum (HyClone) and 10 mM N-2-hydroxyethylpiperazine- N'-2-ethanesulfonic acid (HEPES) (Gibco BRL). The cell suspension is centrifuged in a cytospin (Shandon Southern Instruments, Sewickley, PA) and stained by Diff Quick (American Scientific Products, McGraw Park, IL) to differentiate BAL leukocytes into neutrophil, eosinophil, monocyte, or lymphocyte subsets. The number of eosinophils in the BAL fluid is determined by multiplying the percentage of eosinophils by the total cell count. BIOLOGICAL EXAMPLE 6 Human Lysate 15-LO Assay (HUM15LO): The HUM15LO assay measures inhibition of 15-LO catalyzed oxidation of linoleic acid to the hydroperoxy fatty acid 13-(S)HPODE, a conjugated diene. In the HUM15LO assay, a test compound was incubated with 15-LO enzyme in the presence of the linoleic acid substrate. For example, a known amount of a compound of the present invention and 100 μL of human 15-LO and 174 μM of linoleic acid in PBS containing 0.2% sodium cholate were incubated for 15 minutes at 4°C. The test reaction was stopped with 100 μL of mobile phase and 10 μL of triethyl phosphite. 13-(S)HPODE was reduced with triethyl phosphite to the more stable 13-hydroxyoctadecadienoate (13-HODE), which prevents artificial, nonenzymatic Hpidperoxidation and product breakdown in the sample. 13-HPODE was quantitated by comparing peak areas of individual samples with those from a standard curve generated using authentic 13-HODE. The test reaction was compared to a control reaction, which is identical to the test reaction except a test compound is not present. Percent inhibition was calculated as the amount of 13-HODE produced in the test reaction divided by the amount of 13-HODE produced in the control reaction, expressed as a percent. Human 15-LO was generated in a recombinant 15-lipoxygenase bacculovirus expression system, using Gibco/BRL/Life Technologies' Bac-to-Bac expression reagents; T4 DNA ligase, Kanamycin, Gentamicin, tetracycline, penicillin, streptomycin, Bluo-gal, IPTG, DHlOBac competent cells, SOC, LB medium, Sf-900 II SFM media, Sf9 insect cells, Cell Fectin, and EcoRI, BamHI, and Kpnl restriction enzymes. Human lysate data for representative compounds: 5-(3H-Imidazo[4,5-b]pyridin-2-yl)-2-methoxy-phenylamine (Chemical Example 1): 39% inhibition at 10 μM; and Thiophene-2-sulfonic acid [5-(3H-Imidazo[4,5-b]pyridin-2-yl)~2-methoxy- phenyl]-amide (Chemical Example 2): IC50 = 10 μM.
