The present invention relates generally to amide containing heterobicyclic metalloprotease inhibiting compounds, and more particularly to heterobicyclic MMP-13 inhibiting compounds.
Matrix metalloproteinases (MMPs) and aggrecanases (ADAMTS=a disintegrin and metalloproteinase with thrombospondin motif) are a family of structurally related zinc-containing enzymes that have been reported to mediate the breakdown of connective tissue in normal physiological processes such as embryonic development, reproduction, and tissue remodelling. Over-expression of MMPs and aggrecanases or an imbalance between extracellular matrix synthesis and degradation has been suggested as factors in inflammatory, malignant and degenerative disease processes. MMPs and aggrecanases are, therefore, targets for therapeutic inhibitors in several inflammatory, malignant and degenerative diseases such as rheumatoid arthritis, osteoarthritis, osteoporosis, periodontitis, multiple sclerosis, gingivitis, corneal epidermal and gastric ulceration, atherosclerosis, neointimal proliferation (which leads to restenosis and ischemic heart failure) and tumor metastasis.
The ADAMTSs are a group of proteases that are encoded in 19 ADAMTS genes in humans. The ADAMTSs are extracellular, multidomain enzymes whose functions include collagen processing, cleavage of the matrix proteoglycans, inhibition of angiogenesis and blood coagulation homoeostasis (Biochem. J. 2005, 386, 15-27; Arthritis Res. Ther. 2005, 7, 160-169; Curr. Med. Chem. Anti-Inflammatory Anti-Allergy Agents 2005, 4, 251-264).
The mammalian MMP family has been reported to include at least 20 enzymes, (Chem. Rev. 1999, 99, 2735-2776). Collagenase-3 (MMP-13) is among three collagenases that have been identified. Based on identification of domain structures for individual members of the MMP family, it has been determined that the catalytic domain of the MMPs contains two zinc atoms; one of these zinc atoms performs a catalytic function and is coordinated with three histidines contained within the conserved amino acid sequence of the catalytic domain. MMP-13 is over-expressed in rheumatoid arthritis, osteoarthritis, abdominal aortic aneurysm, breast carcinoma, squamous cell carcinomas of the head and neck, and vulvar squamous cell carcinoma. The principal substrates of MMP-13 are fibrillar collagens (types I, II, III) and gelatins, proteoglycans, cytokines and other components of ECM (extracellular matrix).
The activation of the MMPs involves the removal of a propeptide, which features an unpaired cysteine residue complexes the catalytic zinc (II) ion. X-ray crystal structures of the complex between MMP-3 catalytic domain and TIMP-1 and MMP-14 catalytic domain and TIMP-2 also reveal ligation of the catalytic zinc (II) ion by the thiol of a cysteine residue. The difficulty in developing effective MMP inhibiting compounds comprises several factors, including choice of selective versus broad-spectrum MMP inhibitors and rendering such compounds bioavailable via an oral route of administration.
The present invention relates to a new class of heterobicyclic amide containing pharmaceutical agents which inhibits metalloproteases. In particular, the present invention provides a new class of metalloprotease inhibiting compounds that exhibit potent MMP-13 inhibiting activity and/or activity towards MMP-3, MMP-8, MMP-12, ADAMTS-4, and ADAMTS-5.

The term “N-oxide” denotes compounds that can be obtained in a known manner by reacting a compound of the present invention including a nitrogen atom (such as in a pyridyl group) with hydrogen peroxide or a peracid, such as 3-chloroperoxy-benzoic acid, in an inert solvent, such as dichloromethane, at a temperature between about −10-80° C., desirably about 0° C.
The term “polymorph” denotes a form of a chemical compound in a particular crystalline arrangement. Certain polymorphs may exhibit enhanced thermodynamic stability and may be more suitable than other polymorphic forms for inclusion in pharmaceutical formulations.
The compounds of the invention can contain one or more chiral centers and/or double bonds and, therefore, exist as stereoisomers, such as double-bond isomers (i.e., geometric isomers), enantiomers, or diastereomers. According to the invention, the chemical structures depicted herein, and therefore the compounds of the invention, encompass all of the corresponding enantiomers and stereoisomers, that is, both the stereomerically pure form (e.g., geometrically pure, enantiomerically pure, or diastereomerically pure) and enantiomeric and stereoisomeric mixtures.
The term “racemic mixture” denotes a mixture that is about 50% of one enantiomer and about 50% of the corresponding enantiomer relative to all chiral centers in the molecule. Thus, the invention encompasses all enantiomerically-pure, enantiomerically-enriched, and racemic mixtures of compounds of Formulas (I) through (VI).
Enantiomeric and stereoisomeric mixtures of compounds of the invention can be resolved into their component enantiomers or stereoisomers by well-known methods. Examples include, but are not limited to, the formation of chiral salts and the use of chiral or high performance liquid chromatography “HPLC” and the formation and crystallization of chiral salts. See, e.g., Jacques, J., et al., Enantiomers, Racemates and Resolutions (Wiley-Interscience, New York, 1981); Wilen, S. H., et al., Tetrahedron 33:2725 (1977); Eliel, E. L., Stereochemistry of Carbon Compounds (McGraw-Hill, NY, 1962); Wilen, S. H., Tables of Resolving Agents and Optical Resolutions p. 268 (E. L. Eliel, Ed., Univ. of Notre Dame Press, Notre Dame, Ind., 1972); Stereochemistry of Organic Compounds, Ernest L. Eliel, Samuel H. Wilen and Lewis N. Manda (1994 John Wiley & Sons, Inc.), and Stereoselective Synthesis A Practical Approach, Mihaly Nogradi (1995 VCH Publishers, Inc., NY, N.Y.). Enantiomers and stereoisomers can also be obtained from stereomerically- or enantiomerically-pure intermediates, reagents, and catalysts by well-known asymmetric synthetic methods.
“Substituted” is intended to indicate that one or more hydrogens on the atom indicated in the expression using “substituted” is replaced with a selection from the indicated group(s), provided that the indicated atom's normal valency is not exceeded, and that the substitution results in a stable compound. When a substituent is keto (i.e., ═O) group, then 2 hydrogens on the atom are replaced.

In some embodiments the compounds of Formula (I)-(III) are synthesized by the general methods shown in Scheme 1 to Scheme 3.
Methyl acetopyruvate is condensed (e.g. MeOH/reflux, aqueous HCl/100° C. or glacial AcOH/95° C.) with an amino substituted 5-membered heterocycle (e.g. 1H-pyrazol-5-amine) to afford a bicyclic ring system as a separable mixture of regioisomer A and regioisomer B (Scheme 1).
The regioisomer A of the bicyclic ring system from Scheme 1 (e.g. 7-methyl-pyrazolo[1,5-a]pyrimidine-5-carboxylic acid methyl ester) is oxidized (e.g. selenium dioxide/120-130° C. and then oxone®/room temperature) to afford the corresponding carboxylic acid (Scheme 2). Activated acid coupling (e.g. oxalyl chloride, PyBOP, PyBrOP, EDCI/HOAt or HATU/HOAt) with RARBNH (e.g. 4-fluoro-3-methyl-benzylamine) in a suitable solvent gives the desired amide after purification. Saponification (e.g. aqueous LiOH/dioxane, NaOH/MeOH or TMSnOH/80° C.) and further activated acid coupling (e.g. oxalyl chloride, PyBOP, PyBrOP, EDCI/HOAt, HATU/HOAt, N-cyclohexyl-carbodiimide-N′-methyl-polystyrene or polystyrene-IIDQ) with RCRDNH gives the desired bicyclic bisamide inhibitor after purification. If necessary, the R group can be further manipulated (e.g. saponification of a COOMe group in R).
The regioisomer B of the bicyclic ring system from Scheme 1 (e.g. 5-methyl-pyrazolo[1,5-a]pyrimidine-7-carboxylic acid methyl ester) is treated similarly as shown in Scheme 2 to give the desired bicyclic bisamide inhibitor after purification (Scheme 3). If necessary, the R group can be further manipulated (e.g. saponification of a COOMe group in R).

2-Chloro-6-methyl-pyrimidine-4-carboxylic acid methyl ester is reduced (e.g. NaBH4/MeOH) to the corresponding alcohol and protected with a suitable protecting group [PG, e.g. (2-methoxyethoxy)methyl] (Scheme 4). The obtained intermediate is stirred with hydrazine hydrate at 70° C. to afford the corresponding hydrazino pyrimidine after concentration. Cyclization with a suitable reagent (e.g. triethylortho formate) gives the protected hydroxymethyl substituted bicyclic ring system as a separable mixture of regioisomer A and regioisomer B.
The regioisomer A of the protected hydroxymethyl substituted bicyclic ring system from Scheme 4 (e.g. 7-(2-methoxy-ethoxymethoxymethyl)-5-methyl-[1,2,4]triazolo[4,3-a]pyrimidine) is deprotected (e.g. HCl/THF) and then oxidized (e.g. KMnO4 in aqueous Na2CO3/50° C.) to afford the corresponding carboxy substituted bicyclic ring system (Scheme 5). Esterifcation (e.g. thionyl chloride/MeOH) and oxidation (e.g. selenium dioxide/70° C.) of this intermediate gives the corresponding carboxylic acid. Activated acid coupling (e.g. oxalyl chloride, PyBOP, PyBrOP, EDCI/HOAt or HATU/HOAt) with RARBNH (e.g. 4-fluoro-3-methyl-benzylamine) in a suitable solvent gives the desired amide after purification. Saponification (e.g. aqueous LiOH/dioxane, NaOH/MeOH or TMSnOH/80° C.) and further activated acid coupling (e.g. oxalyl chloride, PyBOP, PyBrOP, EDCI/HOAt, HATU/HOAt) with RCRDNH gives the desired bicyclic bisamide inhibitor after purification. If necessary, the R group can be further manipulated (e.g. saponification of a COOMe group in R).

If necessary, the R group can be further manipulated (e.g. saponification of a COOMe group in R).
2-Chloro-6-methyl-pyrimidine-4-carboxylic acid methyl ester is oxidized (e.g. selenium dioxide/105° C.) to the corresponding carboxylic acid (Scheme 7). Activated acid coupling (e.g. oxalyl chloride) with RARBNH (e.g. 4-fluoro-3-methyl-benzylamine) in a suitable solvent gives the desired amide after purification. Saponification (e.g. aqueous LiOH/THF) and further activated acid coupling (e.g. PyBOP) with RCRDNH (e.g. 4-aminomethyl-benzoic acid methyl ester) gives the corresponding benzotriazol-1-yloxy substituted pyrimidine bisamide.
A benzotriazol-1-yloxy substituted pyrimidine bisamide from Scheme 7 (e.g. 4-({[2-(benzotriazol-1-yloxy)-6-(4-fluoro-3-methyl-benzylcarbamoyl)-pyrimidine-4-carbonyl]-amino}-methyl)-benzoic acid methyl ester) is stirred with hydrazine hydrate at room temperature to afford the corresponding hydrazino pyrimidine bisamide after concentration (Scheme 8). Cyclization with a suitable reagent (e.g. phosgene) gives the corresponding bicyclic bisamide inhibitor as a mixture of regioisomer A and regioisomer B. If necessary, the R group can be further manipulated (e.g. saponification of a COOMe group in R).
In some embodiments the compounds of Formula (IV)-(VI) are synthesized by the general methods shown in Scheme 9 to Scheme 11.
An ester and amino substituted heterocycle (e.g. 3-amino-1H-pyrrole-2-carboxylic acid ethyl ester) is condensed (e.g. EtOH/reflux) with formamidine to give a hydroxy substituted bicyclic ring system (Scheme 9). This intermediate is then converted into the corresponding bromo derivative using a suitable reagent (e.g. POBr3/80° C.). The resulting bromide is heated to (e.g. 80° C.) with a suitable catalyst (e.g. Pd(OAc)2, dppf) and base (e.g. Et3N) under a carbon monoxide atmosphere in a suitable solvent (e.g. MeOH) to give the corresponding bicyclic methylester after purification. Nitration (e.g. concentrated HNO3/0° C. to room temperature) and saponification (e.g. aqueous LiOH) gives the corresponding nitro substituted bicyclic carboxylic acid. Activated acid coupling (e.g. EDCI/HOAt) with RARBNH (e.g. 6-aminomethyl-4H-benzo[1,4]oxazin-3-one) in a suitable solvent gives the desired amide. This intermediate is stirred with a suitable catalyst (e.g. Pd/C) and acid (e.g. AcOH) under a hydrogen atmosphere to afford corresponding amino substituted bicyclic amide after purification.
The amino substituted bicyclic amide from scheme 9 (e.g. 3-amino-1H-pyrazolo[4,3-d]pyrimidine-7-carboxylic acid 3-chloro-4-fluoro-benzylamide) and the carbonyl compound (CO)RCRD (e.g. 4-fluorobenzaldehyde) is stirred with a suitable reducing agent (e.g. NaCNBH3) and a small amount of acid (e.g. AcOH) in a suitable solvent (e.g. MeOH) to give the corresponding bicyclic inhibitor after purification (Scheme 10). If necessary, the R group can be further manipulated (e.g. saponification of a COOMe group in R).

If necessary, the R group can be further manipulated (e.g. saponification of a COOMe group in R).
