BACKGROUND OF THE INVENTION
Matrix metalloproteinases (MMPs) 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 remodeling as well as pathological conditions such as rheumatoid arthritis (RA), osteoarthritis (OA), osteoporosis, atherosclerosis and tumor metastasis. MMP family comprises of more than 20 members in human including collagenases (MMP-1, MMP-8, MMP-13), gelatinases (MMP-2, MMP-9), stromelysins (MMP-3, MMP-10, MMP-11), matrilysins (MMP-7, MMP-26), membrane-type (MMP-14, MMP-15, MMP-16, MMP-17, MMP-24, MMP-25), as well as metalloelastases (MMP-12, MMP-19, MMP-20, MMP-22, MMP-23) (Nat Rev Drug Discov., 2007, 6, 480-98).
The most significant members of the MMP family with respect to OA pathology are the collagenases (MMP-1, -8, and -13) which are responsible for type II collagen breakdown (Nat Rev Drug Discov 2007, 6, 480-98; Semin Cell Dev Biol, 2008, 19, 61-8). In recent years, increasing evidence suggests that MMP-13 is the main collagenase responsible for degradation of type II collagen in OA. MMP-13 is not found in normal adult tissues but is specifically expressed in the articular cartilage of OA patients (J Rheumato., 11996, 23, 590-5; J Clin Invest 1996, 97, 2011-9; J Clin Inves., t1996, 97, 761-8; J Clin Invest., 1997, 99, 1534-45). Analysis of human OA cartilage shows a correlation between presence of MMP-13 and MMP-specific collagen cleavage products with disease severity (Arthritis Rheum., 1983, 26, 63-8; J Rheumatol., 2005, 32, 876-86). In vitro data demonstrate that MMP-13 selective inhibitors prevent cytokine-induced collagen loss in human and bovine cartilage ex-plant cultures (Arthritis Rheum. 2009, 60, 2008-18; J Biol Chem 2007 282, 27781-91).
Preclinical models of OA have elevated MMP-13 expression and MMP-13-induced collagen cleavage products in cartilage, synovial fluid, and urine which have been shown to correlate with disease progression (Osteoarthritis Cartilage 2005 13, 139-45; Arthritis Rheum., 1998 41, 877-90). Transgenic mice expressing active human MMP-13 through a cartilage-specific promoter demonstrate pathological changes in articular cartilage of the mouse joints similar to those observed in human OA (J Clin Invest., 2001 107, 35-44; Arthritis Rheum., 2003 48, 1077). In contrast, MMP-13 deficient mice show significantly reduced cartilage degradation as compared to the wild-type following destabilization of the medial meniscus (Arthritis Rheum., 2009 60, 3723-33). Lastly, an orally active MMP-13 selective inhibitor was chondroprotective in rat medial meniscus tear (MMT), rabbit and dog anterior cruciate ligament/medial menisectomy models of OA (Arthritis Rheum., 2009 60, 2008-18; J Biol. Chem., 2007 282, 27781-91, Arthritis Rheum., 2010 62, 3006-15). Taken together, these data indicate that MMP-13 plays an important role in development and progression of the OA in preclinical models and that selective inhibition of MMP-13 can halt breakdown of cartilage thereby preventing joint destruction.
The catalytic zinc domain in MMPs has been the primary focus of inhibitor design. The modification of substrates by introducing zinc chelating groups has generated potent inhibitors such as peptide hydroxamates and thiol-containing peptides (Drug Discov Today, 2007 12, 640-6). Over the last 10-15 years, many non-selective MMP inhibitors have advanced to Phase II clinical trials in treatment of diseases such as cancer, rheumatoid arthritis and OA. However, none of these inhibitors have advanced to late stage trials due to a number of significant challenges: A) Highly variable pharmacokinetics and often poor oral bioavailability. B) All of these non-selective inhibitors target the zinc-binding site which is common to all matrix metalloproteinases. The clinical utility of non-selective MMP inhibitors has been restricted by dose-dependent musculoskeletal effects in humans [joint stiffness, inflammation, pain in arms and shoulders termed “musculoskeletal syndrome” (MSS)] (Arthritis Res Ther., 2007 9, R109). No specific MMP has been implicated in MSS and it is believed that non-selective inhibition of multiple MMPs is the primary cause of this toxicity. Although no specific MMP has been implicated in MSS, there is substantial evidence that MMP-13 does not play a major role in development of MSS. Clinical data from humans with mis-sense mutation of MMP13 are characterized by defective growth and modeling of vertebrae and long bones and do not exhibit signs of MSS (J Clin Invest., 2005 115, 2832-42). Preclinical data from mice deficient of MMP-13 also demonstrate growth defects but no histological signs of fibrodysplasia (MSS) (Development, 2004 131, 5883-95). Finally, a 2-week rat model of fibrodysplasia (MSS) study has shown that animals dosed with a highly selective MMP-13 inhibitor do not develop histological signs of fibrodysplasia as compared to animals dosed with a pan-MMP inhibitor (Arthritis Rheum., 2009 60, 2008-18); (J Biol Chem 2007 282, 27781-91).
Hence, there continues to be a need to find new selective MMP-13 inhibitors with an acceptable therapeutic window making them clinically attractive in the treatment of diseases.

Compounds of Formula (I) of the invention can be used alone or in combination with an additional agent, e.g., a therapeutic agent, said additional agent being selected by the skilled artisan for its intended purpose. For example, the additional agent can be a therapeutic agent art-recognized as being useful to treat the disease or condition being treated by the compound of the present invention. The additional agent also can be an agent that imparts a beneficial attribute to the therapeutic composition e.g., an agent that affects the viscosity of the composition.
It should further be understood that the combinations which are to be included within this invention are those combinations useful for their intended purpose. The agents set forth below are illustrative for purposes and not intended to be limited. The combinations, which are part of this invention, can be the compounds of the present invention and at least one additional agent selected from the lists below. The combination can also include more than one additional agent, e.g., two or three additional agents if the combination is such that the formed composition can perform its intended function.
Preferred combinations are non-steroidal anti-inflammatory drug(s) also referred to as NSAIDS which include drugs like ibuprofen. Other preferred combinations are corticosteroids including prednisolone; the well known side-effects of steroid use can be reduced or even eliminated by tapering the steroid dose required when treating patients in combination with the compounds of this invention. Non-limiting examples of therapeutic agents for rheumatoid arthritis with which a compound of Formula (I) of the invention can be combined include the following: cytokine suppressive anti-inflammatory drug(s) (CSAIDs); antibodies to or antagonists of other human cytokines or growth factors, for example, TNF, LT, IL-1, IL-2, IL-3, IL-4, IL-5, IL-6, IL-7, IL-8, IL-12, IL-15, IL-16, IL-21, IL-23, interferons, EMAP-II, GM-CSF, FGF, and PDGF.

In this invention, the following definitions are applicable:
A “therapeutically effective amount” is an amount of a compound of Formula (I) or a combination of two or more such compounds, which inhibits, totally or partially, the progression of the condition or alleviates, at least partially, one or more symptoms of the condition. A therapeutically effective amount can also be an amount which is prophylactically effective. The amount which is therapeutically effective will depend upon the patient's size and gender, the condition to be treated, the severity of the condition and the result sought. For a given patient, a therapeutically effective amount can be determined by methods known to those of skill in the art.
“Pharmaceutically acceptable salts” refers to those salts which retain the biological effectiveness and properties of the free bases and which are obtained by reaction with inorganic acids, for example, hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, and phosphoric acid or organic acids such as sulfonic acid, carboxylic acid, organic phosphoric acid, methanesulfonic acid, ethanesulfonic acid, p-toluenesulfonic acid, citric acid, fumaric acid, maleic acid, succinic acid, benzoic acid, salicylic acid, lactic acid, tartaric acid (e.g. (+) or (−)-tartaric acid or mixtures thereof), amino acids (e.g. (+) or (−)-amino acids or mixtures thereof), and the like. These salts can be prepared by methods known to those skilled in the art.
Certain compounds of Formula (I) which have acidic substituents may exist as salts with pharmaceutically acceptable bases. The present invention includes such salts. Examples of such salts include sodium salts, potassium salts, lysine salts, TRIS salts, meglumine salts and arginine salts. These salts may be prepared by methods known to those skilled in the art.
Certain compounds of Formula (I) and their salts may exist in more than one crystal form and the present invention includes each crystal form and mixtures thereof.
Certain compounds of Formula (I) and their salts may also exist in the form of solvates, for example hydrates, and the present invention includes each solvate and mixtures thereof.
Certain compounds of Formula (I) may contain one or more chiral centers, and exist in different optically active forms. When compounds of Formula (I) contain one chiral center, the compounds exist in two enantiomeric forms and the present invention includes both enantiomers and mixtures of enantiomers, such as racemic mixtures. The enantiomers may be resolved by methods known to those skilled in the art, for example by formation of diastereoisomeric salts which may be separated, for example, by crystallization; formation of diastereoisomeric derivatives or complexes which may be separated, for example, by crystallization, gas-liquid or liquid chromatography; selective reaction of one enantiomer with an enantiomer-specific reagent, for example enzymatic esterification; or gas-liquid or liquid chromatography in a chiral environment, for example on a chiral support for example silica with a bound chiral ligand or in the presence of a chiral solvent. It will be appreciated that where the desired enantiomer is converted into another chemical entity by one of the separation procedures described above, a further step is required to liberate the desired enantiomeric form. Alternatively, specific enantiomers may be synthesized by asymmetric synthesis using optically active reagents, substrates, catalysts or solvents, or by converting one enantiomer into the other by asymmetric transformation.
When a compound of Formula (I) contains more than one chiral center, it may exist in diastereoisomeric forms. The diastereoisomeric compounds may be separated by methods known to those skilled in the art, for example chromatography or crystallization and the individual enantiomers may be separated as described above. The present invention includes each diastereoisomer of compounds of Formula (I), and mixtures thereof.
Certain compounds of Formula (I) may exist in different tautomeric forms or as different geometric isomers, and the present invention includes each tautomer and/or geometric isomer of compounds of Formula (I) and mixtures thereof.
Certain compounds of Formula (I) may exist in different stable conformational forms which may be separable. Torsional asymmetry due to restricted rotation about an asymmetric single bond, for example because of steric hindrance or ring strain, may permit separation of different conformers. The present invention includes each conformational isomer of compounds of Formula (I) and mixtures thereof.
Certain compounds of Formula (I) may exist in zwitterionic form and the present invention includes each zwitterionic form of compounds of Formula (I) and mixtures thereof.
As used herein the term “pro-drug” refers to an agent which is converted into the parent drug in vivo by some physiological chemical process (e.g., a pro-drug on being brought to the physiological pH is converted to the desired drug form). Pro-drugs are often useful because, in some situations, they may be easier to administer than the parent drug. They may, for instance, be bioavailable by oral administration whereas the parent drug is not. The pro-drug may also have improved solubility in pharmacological compositions over the parent drug. An example, without limitation, of a pro-drug would be a compound of the present invention wherein it is administered as an ester (the “pro-drug”) to facilitate transmittal across a cell membrane where water solubility is not beneficial, but then it is metabolically hydrolyzed to the carboxylic acid once inside the cell where water solubility is beneficial.
Pro-drugs have many useful properties. For example, a pro-drug may be more water soluble than the ultimate drug, thereby facilitating intravenous administration of the drug. A pro-drug may also have a higher level of oral bioavailability than the ultimate drug. After administration, the pro-drug is enzymatically or chemically cleaved to deliver the ultimate drug in the blood or tissue.
Exemplary pro-drugs upon cleavage release the corresponding free acid, and such hydrolyzable ester-forming residues of the compounds of this invention include but are not limited to carboxylic acid substituents wherein the free hydrogen is replaced by (C1-C4)alkyl, (C1-C12)alkanoyloxymethyl, (C4-C9)1-(alkanoyloxy)ethyl, 1-methyl-1-(alkanoyloxy)-ethyl having from 5 to 10 carbon atoms, alkoxycarbonyloxymethyl having from 3 to 6 carbon atoms, 1-(alkoxycarbonyloxy)ethyl having from 4 to 7 carbon atoms, 1-methyl-1-(alkoxycarbonyloxy)ethyl having from 5 to 8 carbon atoms, N-(alkoxycarbonyl)aminomethyl having from 3 to 9 carbon atoms, 1-(N-(alkoxycarbonyl)amino)ethyl having from 4 to 10 carbon atoms, 3-phthalidyl, 4-crotonolactonyl, gamma-butyrolacton-4-yl, di-N,N—(C1-C2)alkylamino(C2-C3)alkyl (such as (3-dimethylaminoethyl), carbamoyl-(C1-C2)alkyl, N,N-di(C1-C2)-alkylcarbamoyl-(C1-C2)alkyl and piperidino-, pyrrolidino- or morpholino(C2-C3)alkyl.
Other exemplary pro-drugs release an alcohol of Formula (I) wherein the free hydrogen of the hydroxyl substituent is replaced by (C1-C6)alkanoyloxymethyl, 1-((C1-C6)alkanoyloxy)ethyl, 1-methyl-1-((C1-C6)alkanoyloxy)ethyl, (C1-C2)alkoxycarbonyloxymethyl, N—(C1-C6)alkoxycarbonylamino-methyl, succinoyl, (C1-C6)alkanoyl, α-amino(C1-C4)alkanoyl, arylacetyl and α-aminoacyl, or α-aminoacyl-α-aminoacyl wherein said α-aminoacyl moieties are independently any of the naturally occurring L-amino acids found in proteins, P(O)(OH)2, —P(O)(O(C1-C6)alkyl)2 or glycosyl (the radical resulting from detachment of the hydroxyl of the hemiacetal of a carbohydrate).
Other exemplary pro-drugs release an amine of Formula (I) wherein the free hydrogen of the amine group is replaced by —C(O)alkyl, —C(O)O-alkyl, N-phosphonoxyalkyl, alkyl, cycloalkyl, aryl, heteroaryl or heterocyclyl, wherein the alkyl, cycloalkyl, aryl, heteroaryl or heterocyclyl can be optionally substituted with, for example, halogen and hydroxyl.
The term “heterocyclic”, “heterocyclyl” or “heterocyclylene”, as used herein, include non-aromatic ring systems, including, but not limited to, monocyclic, bicyclic, and tricyclic rings, which can be completely saturated or which can contain one or more units of unsaturation. (for the avoidance of doubt, the degree of unsaturation does not result in an aromatic ring system) and have 5 to 12 atoms including at least one heteroatom, such as nitrogen, oxygen, or sulfur. For purposes of exemplification, which should not be construed as limiting the scope of this invention, the following are examples of heterocyclic rings: azepinyl, azetidinyl, 1,4-dioxanyl, indolinyl, isoindolinyl, morpholinyl, piperazinyl, piperidinyl, pyrrolidinyl, quinucludinyl, thiomorpholinyl, tetrahydropyranyl, tetrahydrofuranyl, tetrahydroindolyl, thiomorpholinyl and tropanyl.

For example when a ring system is termed aromatic, it should have its it electrons in the ring in accordance with the requirement to possess aromaticity. In the case where a ring system becomes partly aromatic, it means one of the cyclic rings is aromatic and the ring to which it is fused is non-aromatic. All non-aromatic ring systems do not comply with the definition of aromaticity known to person having ordinary skill in the art.

The term “heteroaryl” or “heteroarylene” as used herein, include aromatic ring systems, including, but not limited to, monocyclic, bicyclic and tricyclic rings, and have 5 to 12 atoms including at least one heteroatom, such as nitrogen, oxygen, or sulfur.

As used herein, “alkyl” and “alkylene” include straight chained or branched hydrocarbons which are completely saturated. For purposes of exemplification, which should not be construed as limiting the scope of this invention, examples of alkyls are methyl, ethyl, propyl, isopropyl, butyl, pentyl, hexyl and isomers thereof.

As used herein, “aryl” or “arylene” groups include aromatic carbocyclic ring systems (e.g. phenyl) and fused polycyclic aromatic ring systems. For purposes of exemplification, which should not be construed as limiting the scope of this invention, aryl groups include phenyl, naphthyl, biphenyl and 1,2,3,4-tetrahydronaphthyl.
As used herein, “cycloalkyl” or “cycloalkylene” means C3-C12 monocyclic or multicyclic (e.g., bicyclic, tricyclic, etc.) hydrocarbons that are completely saturated or have one or more unsaturated bonds but do not amount to an aromatic group. For purposes of exemplification, which should not be construed as limiting the scope of this invention, examples of a cycloalkyl group are cyclopropyl, cyclobutyl, cyclopentyl, cyclopentenyl, cyclohexyl and cyclohexenyl.
As used herein, many moieties (i.e. alkyl, alkylene, cycloalkyl, cycloalkylene, aryl, arylene, heteroaryl, heteroarylene, heterocyclyl or heterocyclylene) or substituents are referred to as being either “substituted” or “optionally substituted”. When a moiety is modified by one of these terms, unless otherwise noted, it denotes that any portion of the moiety that is known to one skilled in the art as being available for substitution can be substituted, which includes one or more substituents, where if more than one substituent are present, then each substituent may be independently selected. Such means for substitution are well-known in the art and/or taught by the instant disclosure. For purposes of exemplification, which should not be construed as limiting the scope of this invention, some examples of groups that are substituents: deuterium, optionally substituted (C1-C8)alkyl groups, optionally substituted (C2-C8) alkenyl groups, (C2-C8) alkynyl groups, optionally substituted (C3-C10)cycloalkyl groups, optionally substituted (C1-C8) alkoxy groups, halogen (F, Cl, Br or I), halogenated (C1-C8) alkyl groups (for example but not limited to —CF3), optionally substituted heterocyclyl groups, optionally substituted heteroaryl groups, —OH, —SH, —optionally substituted —(C1-C8) alkoxy, —optionally substituted —(C1-C8) thio alkoxy, —NH(C1-C8)alkyl groups, —N((C1-C8)alkyl)2 groups, —NH2, —NH—(C3-C6) cycloalkyl, —NH—(C1-C6)alkyl-optionally substituted heterocycle, —NH-heterocycle, —C(O)-optionally substituted (C1-C8)alkyl groups, —C(O)NH2, —C(O)NH(C1-C8)-optionally substituted alkyl, —C(O)N((C1-C8)alkyl)2, —C(O)NH—O—(C1-C8)alkyl, —C(O)N(C1-C8)alkyl-O—(C1-C8)alkyl, —C(O)NH-optionally substituted heteroaryl, —C(O)H, —C(O)—(C1-C8)alkyl groups, —C(O)-optionally substituted (C3-C10) cyclo alkyl groups, —C(O)OH, —C(O)O(C1-C8)alkyl groups, —NHC(O)H, —NHC(O)(C1-C8) optionally substituted alkyl groups, —NHC(O)(C3-C8) optionally substituted cycloalkyl groups, —N((C1-C8)alkyl)C(O)H, —N((C1-C8)alkyl)C(O)(C1-C8) optionally substituted alkyl groups, —NHC(O)NH2, —NHC(O)NH-optionally substituted (C1-C8)alkyl groups, —N((C1-C8)alkyl)C(O)NH2 groups, —NHC(O)N-optionally substituted ((C1-C8)alkyl)2 groups, —N((C1-C8)alkyl)C(O)N((C1-C8)alkyl)2 groups, —N((C1-C8)alkyl)C(O)NH((C1-C8)alkyl), —NHS(O)2—(C1-C8) optionally substituted alkyl, —NHS(O)2NH2, —NHS(O)2NH(C1-C6)alkyl, —NHS(O)2N(C1-C6)alkyl)2, —CN, —NO2, —O—C(O)—(C1-C8)alkyl, —O—S(O)2-heteroaryl, —O—S(O)2-aryl, —S(C1-C8)alkyl groups, —S(O)(C1-C8)alkyl groups, —S(O)2(C1-C8)alkyl groups, —S(O)2(C3-C10)cycloalkyl groups, —S(O)2N((C1-C8)alkyl)2 groups, —S(O)2NH(C1-C8)alkyl groups, —S(O)2NH(C3-C8)cycloalkyl groups, —S(O)2NH2 groups, —S(O)2-optionally substituted heteroaryl groups, —S(O)2-optionally substituted heterocyclyl groups, —NHS(O)2(C1-C8)alkyl groups, —N((C1-C8)alkyl)S(O)2(C1-C8)alkyl groups, —(C1-C8)alkyl-O—(C1-C8)alkyl groups, —O—(C1-C8)alkyl-O—(C1-C8)alkyl groups, —NHOH, —NHO(C1-C8)alkyl groups, —O-halogenated (C1-C8)alkyl groups (for example but not limited to —OCF3), oxo, —S(O)2-halogenated (C1-C8)alkyl groups (for example but not limited to —S(O)2CF3), —S-halogenated (C1-C8)alkyl groups (for example but not limited to —SCF3), —(C1-C6)alkyl-optionally substituted heterocycle (for example but not limited to azetidine, morpholine, piperidine, piperazine, pyrrolidine, tetrahydrofuran, thiomorpholine, or pyran), —(C1-C6)alkyl-heteroaryl (for example but not limited to tetrazole, imidazole, furan, pyrazine or pyrazole), —optionally substituted phenyl, —NHC(O)O—(C1-C6)alkyl groups, —N((C1-C6)alkyl)C(O)O—(C1-C6)alkyl groups, —C(═NH)—(C1-C6)alkyl groups, —C(═NOH)—(C1-C6)alkyl groups, or —C(═N—O—(C1-C6)alkyl)-(C1-C6)alkyl groups.
One or more compounds of this invention can be administered to a human patient by themselves or in pharmaceutical compositions where they are mixed with biologically suitable carriers or excipient(s) at doses to treat or ameliorate a disease or condition as described herein. Mixtures of these compounds can also be administered to the patient as a simple mixture or in suitable formulated pharmaceutical compositions. A therapeutically effective dose refers to that amount of the compound or compounds sufficient to result in the prevention or attenuation of a disease or condition as described herein. Techniques for formulation and administration of the compounds of the instant application may be found in references well known to one of ordinary skill in the art, such as “Remington's Pharmaceutical Sciences,” Mack Publishing Co., Easton, Pa., latest edition.
Suitable routes of administration may, for example, include oral, eyedrop, rectal, transmucosal, topical, or intestinal administration; parenteral delivery, including intramuscular, subcutaneous, intramedullary injections, as well as intrathecal, direct intraventricular, intravenous, intraperitoneal, intranasal, or intraocular injections.
Alternatively, one may administer the compound in a local rather than a systemic manner, for example, via injection of the compound directly into an edematous site, often in a depot or sustained release formulation.
Furthermore, one may administer the drug in a targeted drug delivery system, for example, in a liposome coated with endothelial cell-specific antibody.
The pharmaceutical compositions of the present invention may be manufactured in a manner that is itself known, e.g., by means of conventional mixing, dissolving, granulating, dragee-making, levigating, emulsifying, encapsulating, entrapping or lyophilizing processes.
Pharmaceutical compositions for use in accordance with the present invention thus may be formulated in a conventional manner using one or more physiologically acceptable carriers comprising excipients and auxiliaries which facilitate processing of the active compounds into preparations which can be used pharmaceutically. Proper formulation is dependent upon the route of administration chosen.
For injection, the agents of the invention may be formulated in aqueous solutions, preferably in physiologically compatible buffers such as Hanks' solution, Ringer's solution, or physiological saline buffer. For transmucosal administration, penetrants appropriate to the barrier to be permeated are used in the formulation. Such penetrants are generally known in the art.
For oral administration, the compounds can be formulated readily by combining the active compounds with pharmaceutically acceptable carriers well known in the art. Such carriers enable the compounds of the invention to be formulated as tablets, pills, dragees, capsules, liquids, gels, syrups, slurries, suspensions and the like, for oral ingestion by a patient to be treated.
Pharmaceutical preparations for oral use can be obtained by combining the active compound with a solid excipient, optionally grinding a resulting mixture, and processing the mixture of granules, after adding suitable auxiliaries, if desired, to obtain tablets or dragee cores. Suitable excipients are, in particular, fillers such as sugars, including lactose, sucrose, mannitol, or sorbitol; cellulose preparations such as, for example, maize starch, wheat starch, rice starch, potato starch, gelatin, gum tragacanth, methyl cellulose, hydroxypropylmethyl-cellulose, sodium carboxymethylcellulose, and/or polyvinylpyrrolidone (PVP). If desired, disintegrating agents may be added, such as the cross-linked polyvinyl pyrrolidone, agar, or alginic acid or a salt thereof such as sodium alginate.
Dragee cores are provided with suitable coatings. For this purpose, concentrated sugar solutions may be used, which may optionally contain gum arabic, talc, polyvinyl pyrrolidone, carbopol gel, polyethylene glycol, and/or titanium dioxide, lacquer solutions, and suitable organic solvents or solvent mixtures. Dyestuffs or pigments may be added to the tablets or dragee coatings for identification or to characterize different combinations of active compound doses.
Pharmaceutical preparations that can be used orally include push-fit capsules made of gelatin, as well as soft, sealed capsules made of gelatin and a plasticizer, such as glycerol or sorbitol. The push-fit capsules can contain the active ingredients in admixture with filler such as lactose, binders such as starches, and/or lubricants such as talc or magnesium stearate and, optionally, stabilizers. In soft capsules, the active compounds may be dissolved or suspended in suitable liquids, such as fatty oils, liquid paraffin, or liquid polyethylene glycols. In addition, stabilizers may be added. All formulations for oral administration should be in dosages suitable for such administration.
For buccal administration, the compositions may take the form of tablets or lozenges formulated in conventional manner.
For administration by inhalation, the compounds for use according to the present invention are conveniently delivered in the form of an aerosol spray presentation from pressurized packs or a nebuliser, with the use of a suitable propellant, e.g., dichlorodifluoromethane, trichlorofluoromethane, dichlorotetrafluoroethane, carbon dioxide or other suitable gas. In the case of pressurized aerosol the dosage unit may be determined by providing a valve to deliver a metered amount. Capsules and cartridges of e.g. gelatin for use in an inhaler or insufflator may be formulated containing a powder mix of the compound and a suitable powder base such as lactose or starch.
The compounds can be formulated for parenteral administration by injection, e.g. bolus injection or continuous infusion. Formulations for injection may be presented in unit dosage form, e.g. in ampoules or in multi-dose containers, with an added preservative. The compositions may take such forms as suspensions, solutions or emulsions in oily or aqueous vehicles, and may contain formulatory agents such as suspending, stabilizing and/or dispersing agents.
Pharmaceutical formulations for parenteral administration include aqueous solutions of the active compounds in water-soluble form. Additionally, suspensions of the active compounds may be prepared as appropriate oily injection suspensions. Suitable lipophilic solvents or vehicles include fatty oils such as sesame oil, or synthetic fatty acid esters, such as ethyl oleate or triglycerides, or liposomes. Aqueous injection suspensions may contain substances which increase the viscosity of the suspension, such as sodium carboxymethyl cellulose, sorbitol, or dextran. Optionally, the suspension may also contain suitable stabilizers or agents which increase the solubility of the compounds to allow for the preparation of highly concentrated solutions.
Alternatively, the active ingredient may be in powder form for constitution with a suitable vehicle, e.g., sterile pyrogen-free water, before use.
The compounds may also be formulated in rectal compositions such as suppositories or retention enemas, e.g., containing conventional suppository bases such as cocoa butter or other glycerides.
In addition to the formulations described previously, the compounds may also be formulated as a depot preparation. Such long acting formulations may be administered by implantation (for example subcutaneously or intramuscularly or by intramuscular injection). Thus, for example, the compounds may be formulated with suitable polymeric or hydrophobic materials (for example as an emulsion in an acceptable oil) or ion exchange resins, or as sparingly soluble derivatives, for example, as a sparingly soluble salt.
An example of a pharmaceutical carrier for the hydrophobic compounds of the invention is a cosolvent system comprising benzyl alcohol, a nonpolar surfactant, a water-miscible organic polymer, and an aqueous phase. The cosolvent system may be the VPD co-solvent system. VPD is a solution of 3% w/v benzyl alcohol, 8% w/v of the nonpolar surfactant polysorbate 80, and 65% w/v polyethylene glycol 300, made up to volume in absolute ethanol. The VPD co-solvent system (VPD:5W) consists of VPD diluted 1:1 with a 5% dextrose in water solution. This co-solvent system dissolves hydrophobic compounds well, and itself produces low toxicity upon systemic administration. Naturally, the proportions of a co-solvent system may be varied considerably without destroying its solubility and toxicity characteristics. Furthermore, the identity of the co-solvent components may be varied: for example, other low-toxicity nonpolar surfactants may be used instead of polysorbate 80; the fraction size of polyethylene glycol may be varied; other biocompatible polymers may replace polyethylene glycol, e.g. polyvinyl pyrrolidone; and other sugars or polysaccharides may substitute for dextrose.
Alternatively, other delivery systems for hydrophobic pharmaceutical compounds may be employed. Liposomes and emulsions are well known examples of delivery vehicles or carriers for hydrophobic drugs. Certain organic solvents such as dimethysulfoxide also may be employed, although usually at the cost of greater toxicity. Additionally, the compounds may be delivered using a sustained-release system, such as semipermeable matrices of solid hydrophobic polymers containing the therapeutic agent. Various sustained-release materials have been established and are well known by those skilled in the art. Sustained-release capsules may, depending on their chemical nature, release the compounds for a few hours up to over several days. Depending on the chemical nature and the biological stability of the therapeutic reagent, additional strategies for protein stabilization may be employed.
The pharmaceutical compositions also may comprise suitable solid or gel phase carriers or excipients. Examples of such carriers or excipients include but are not limited to calcium carbonate, calcium phosphate, various sugars, starches, cellulose derivatives, gelatin, and polymers such as polyethylene glycols.
Many of the compounds of the invention may be provided as salts with pharmaceutically compatible counterions. Pharmaceutically compatible salts may be formed with many acids, including but not limited to hydrochloric, sulfuric, acetic, lactic, tartaric, malic, succinic, etc. Salts tend to be more soluble in aqueous or other protonic solvents than are the corresponding free base forms.
Pharmaceutical compositions suitable for use in the present invention include compositions wherein the active ingredients are contained in an effective amount to achieve its intended purpose. More specifically, a therapeutically effective amount means an amount effective to prevent development of or to alleviate the existing symptoms of the subject being treated. Determination of the effective amounts is well within the capability of those skilled in the art.
For any compound used in a method of the present invention, the therapeutically effective dose can be estimated initially from cellular assays. For example, a dose can be formulated in cellular and animal models to achieve a circulating concentration range that includes the IC50 as determined in cellular assays (i.e., the concentration of the test compound which achieves a half-maximal inhibition of a given protein kinase activity). In some cases it is appropriate to determine the IC50 in the presence of 3 to 5% serum albumin since such a determination approximates the binding effects of plasma protein on the compound. Such information can be used to more accurately determine useful doses in humans. Further, the most preferred compounds for systemic administration effectively inhibit protein kinase signaling in intact cells at levels that are safely achievable in plasma.
A therapeutically effective dose refers to that amount of the compound that results in amelioration of symptoms in a patient. Toxicity and therapeutic efficacy of such compounds can be determined by standard pharmaceutical procedures in cell cultures or experimental animals, e.g., for determining the maximum tolerated dose (MTD) and the ED50 (effective dose for 50% maximal response). The dose ratio between toxic and therapeutic effects is the therapeutic index and it can be expressed as the ratio between MTD and ED50. Compounds which exhibit high therapeutic indices are preferred. The data obtained from these cell culture assays and animal studies can be used in formulating a range of dosage for use in humans. The dosage of such compounds lies preferably within a range of circulating concentrations that include the ED5 s with little or no toxicity. The dosage may vary within this range depending upon the dosage form employed and the route of administration utilized. The exact formulation, route of administration and dosage can be chosen by the individual physician in view of the patient's condition (see e.g. Fingl et al., 1975, in “The Pharmacological Basis of Therapeutics”, Ch. 1 p. 1). In the treatment of crises, the administration of an acute bolus or an infusion approaching the MTD may be required to obtain a rapid response.
Dosage amount and interval may be adjusted individually to provide plasma levels of the active moiety which are sufficient to maintain the kinase modulating effects, or minimal effective concentration (MEC). The MEC will vary for each compound but can be estimated from in vitro data; e.g. the concentration necessary to achieve 50-90% inhibition of protein kinase using the assays described herein. Dosages necessary to achieve the MEC will depend on individual characteristics and route of administration. However, HPLC assays or bioassays can be used to determine plasma concentrations.
Dosage intervals can also be determined using the MEC value. Compounds should be administered using a regimen which maintains plasma levels above the MEC for 10-90% of the time, preferably between 30-90% and most preferably between 50-90% until the desired amelioration of symptoms is achieved. In cases of local administration or selective uptake, the effective local concentration of the drug may not be related to plasma concentration.
The amount of composition administered will, of course, be dependent on the subject being treated, on the subject's weight, the severity of the affliction, the manner of administration and the judgment of the prescribing physician.
The compositions may, if desired, be presented in a pack or dispenser device which may contain one or more unit dosage forms containing the active ingredient. The pack may for example comprise metal or plastic foil, such as a blister pack. The pack or dispenser device may be accompanied by instructions for administration. Compositions comprising a compound of the invention formulated in a compatible pharmaceutical carrier may also be prepared, placed in an appropriate container, and labelled for treatment of an indicated condition.
In some formulations it may be beneficial to use the compounds of the present invention in the form of particles of very small size, for example as obtained by fluid energy milling.
The use of compounds of the present invention in the manufacture of pharmaceutical compositions is illustrated by the following description. In this description the term “active compound” denotes any compound of the invention but particularly any compound which is the final product of one of the following Examples.
a) Capsules
In the preparation of capsules, 10 parts by weight of active compound and 240 parts by weight of lactose can be de-aggregated and blended. The mixture can be filled into hard gelatin capsules, each capsule containing a unit dose or part of a unit dose of active compound.
b) Tablets
Tablets can be prepared, for example, from the following ingredients.

The active compound, the lactose and some of the starch can be de-aggregated, blended and the resulting mixture can be granulated with a solution of the polyvinylpyrrolidone in ethanol. The dry granulate can be blended with the magnesium stearate and the rest of the starch. The mixture is then compressed in a tabletting machine to give tablets each containing a unit dose or a part of a unit dose of active compound.
c) Enteric Coated Tablets
Tablets can be prepared by the method described in (b) above. The tablets can be enteric coated in a conventional manner using a solution of 20% cellulose acetate phthalate and 3% diethyl phthalate in ethanol:dichloromethane (1:1).
d) Suppositories
In the preparation of suppositories, for example, 100 parts by weight of active compound can be incorporated in 1300 parts by weight of triglyceride suppository base and the mixture formed into suppositories each containing a therapeutically effective amount of active ingredient.
In the compositions of the present invention the active compound may, if desired, be associated with other compatible pharmacologically active ingredients. For example, the compounds of this invention can be administered in combination with another therapeutic agent that is known to treat a disease or condition described herein. For example, with one or more additional pharmaceutical agents that inhibit or prevent the production of VEGF or angiopoietins, attenuate intracellular responses to VEGF or angiopoietins, block intracellular signal transduction, inhibit vascular hyperpermeability, reduce inflammation, or inhibit or prevent the formation of edema or neovascularization. The compounds of the invention can be administered prior to, subsequent to or simultaneously with the additional pharmaceutical agent, whichever course of administration is appropriate. The additional pharmaceutical agents include, but are not limited to, anti-edemic steroids, NSAIDS, ras inhibitors, anti-TNF agents, anti-IL1 agents, antihistamines, PAF-antagonists, COX-1 inhibitors, COX-2 inhibitors, NO synthase inhibitors, Akt/PTB inhibitors, IGF-1R inhibitors, PI3 kinase inhibitors, calcineurin inhibitors and immunosuppressants. The compounds of the invention and the additional pharmaceutical agents act either additively or synergistically. Thus, the administration of such a combination of substances that inhibit angiogenesis, vascular hyperpermeability and/or inhibit the formation of edema can provide greater relief from the deletrious effects of a hyperproliferative disorder, angiogenesis, vascular hyperpermeability or edema than the administration of either substance alone. In the treatment of malignant disorders combinations with antiproliferative or cytotoxic chemotherapies or radiation are included in the scope of the present invention.
The present invention also comprises the use of a compound of Formula (I) as a medicament.
The following examples are for illustrative purposes and are not to be construed as limiting the scope of the present invention.

Assays

Time Resolved Fluorescence Resonance Energy Transfer (FRET) Enzyme Assays

    
    


A recombinant human MMP13 catalytic domain (CD) construct encompassing residues 20-274 (SWISS-PROT P45452) was generated by synthetic gene methods and bacterial expression. MMP-13 activity assays were performed using the recombinant human MMP-13 CD at a 0.4 nM concentration and the fluorogenic substrate (QXL-520)-K-P-L-A ̃Nva-Dap(5-FAM)-A-R-NH2 (Anaspec cat #60554-01, San Jose, Calif.) at a 0.25 μM concentration in assay buffer containing 50 μM Tris, pH 7.5, 10 mM CaCl2, 150 mM NaCl, 0.05% Brij 35. The assay is based on the cleavage of this substrate by MMP-13, resulting in decrease of FRET between the donor-acceptor pair and subsequent fluorescence enhancement. The assays were carried out in 384-well plates (Greiner cat #781076, Germany) for 60 min at RT. After the incubation period, the reaction was quenched by the addition of 5 μL of 500 mM EDTA (100 mM final concentration) (Rankem, Cat #E0120, India) mixed well and the rate of substrate hydrolysis was determined by monitoring change in fluorescence at excitation and emission wavelengths of 485 nm and 535 nm respectively. Fluorescence was measured on a Victor V5 plate reader (Perkin Elmer, Turku, Finland). The test compounds used for assessing the potency of inhibition of MMP-13 activity were dissolved in DMSO (final DMSO concentration in the assay was 5%). Selected compounds were also screened against full length MMP13 (R&D Systems (Cat. No. 511-MM-010), Minneapolis, Minn.) at 2 nM concentration using the same fluorogenic substrate mentioned above. The enzyme was activated using 1 m Mp-aminophenylmercuric acetate—APMA (Cat #A-9563, Sigma, Germany).
Selectivity assays for all other MMPs and TACE were performed using the same MMP FRET substrate (0.25 M) and catalytic domain of human MMPs/TACE enzymes. Concentration and catalog number for the enzymes used in the assay were as follows: MMP-2 CD (12.5 nM) (Cat. No. BML-SE237-0010), MMP-3 CD (20 nM) (Cat. No. BML-SE109-0010), MMP-7 CD (12.5 nM) (Cat. No. BML-SE181-0010), MMP-8 CD (3.13 nM) (Cat. No. BML-SE255-0010), MMP-9 CD (1.56 nM) (Cat. No. BML-SE244-0010), MMP-12 CD (1.56 nM) (Cat. No. BML-SE138-0010), MMP-14 CD (10 nM) (Cat. No. BML-SE259-0010) and TACE (25 nM) (Cat. No. PF133). All MMP CD enzymes were purchased from Enzo Life Sciences, Plymouth Meeting, Pa. and TACE enzyme was obtained from EMD Chemical, Gibbstown, N.J.
Selectivity assays for ADAMTS-4 and ADAMTS-5 were performed using TAMRA-G-R-D-V-Q-E ̃F-R-G-V-T-A-V-T-R-K(QSY7)-R-G-R amide as substrate at concentrations of 0.5 μM for ADAMTS-4 and 1 μM for ADAMTS-5. The enzyme concentrations for ADAMTS-4 and ADAMTS-5 were 4 and 25 nM respectively and the rate of substrate hydrolysis was determined by monitoring change in fluorescence at excitation and emission wavelengths of 544 nm and 590 nm. Recombinant human ADAMTS-4 (residues 1-579, SWISS-PROT 075173) and ADAMTS-5 (residues 19-622, SWISS-PROT Q9UNAO) were generated by synthetic gene methods and bacterial expression for the assay.
Data analysis: The percent inhibition of the enzyme activity in presence of test compounds were calculated using the equation, percent (%) Inhibition=100−[(Fi/Fc)*100] where Fc is the fluorescence corresponding to initial enzyme activity and Fi is the fluorescence corresponding to the enzyme activity in presence of inhibitor. The IC50 values were calculated by fitting the dose-response data to a sigmoidal curve fitting equation using Graph Pad prism software (Version 5, La Jolla, Calif.).
Acute Exogenous Full Length MMP-13 Induced Cartilage Degradation in Male Lewis Rats
The test compound was prepared in 1% Tween 80 in 0.5% hydroxypropyl methyl cellulose at desirable concentration for dosing (1, 3, 10, 30, 100 mg/kg). One day before actual start of experiment the hairs around the left knee joint of male LEW/HanTMHsd rats (250-320 g; Harlan Laboratories) were clipped to which activated full length (FL) MMP-13 (prepared in-house; 5 or 10 μg in 100 μL/joint) or 100 μL PBS was injected. The animals were dosed with vehicle or test compounds at 1-10 mL/kg body weight at appropriate time before intra articular administration of FL-MMP-13 protein based on t-max of compounds. At time 0 hour, in vehicle control group, 100 μL filtered Dulbecco's phosphate buffered saline 1× (Invitrogen Ref no. 14190) was injected to left knee joint space using 1⁄2 cc insulin syringes (BD Biosciences Catalogue No. 328468) after anesthetizing with isoflourane (Forane® Abbott Laboratories, USA). For compound treated animal groups, 100 μL of activated FL-MMP-13 was injected. Two hours post challenge with PBS or FL-MMP13, animals were sacrificed using CO2 exposure. Blood was collected from heart puncture into sodium heparin or lithium heparin (100 IU/mL of 0.9% NaCl) vials for plasma drug concentration analysis. Plasma was separated and stored at −20° C. until drug concentration analysis. After sacrifice of animals, 100 μL of filtered Dulbecco's phosphate buffered saline (1×) was injected in to the left knee joint space using a 1⁄2 cc insulin syringe. The synovial fluid was aspirated out and collected into a pre-labeled EDTA tube (BD Biosciences, Catalogue No. 365974) and kept on ice. Synovial fluid samples were spun down for 5 min at 16.1 relative centrifugal force and aliquoted into 96 well polypropylene round bottomed plates, sealed with aluminum seal. Samples were stored at −20° C. until analysis. Synovial fluid wais analyzed for cartilaps (CTX-II) (Immunodiagnostic Systems INC-Nordic bioscience, serum preclinical cartilaps ELISA, catalogue no AC-08F1) as per manufacturer's instructions. Drug concentration in synovial fluid and plasma was estimated by LCMS-MS using a validated method. Lower limit of detection is 1-5 ng/mL.
Cartilaps (CTX-II) levels in synovial fluid of FL-MMP13 injected male Lewis rats treated with vehicle or test compound was subtracted from PBS injected control group synovial fluid levels. The average PBS subtracted CTX-II levels in FL-MMP-13 injected group is considered as 100% response. Mean PBS subtracted CTX-II levels in treated groups were used for calculation of % inhibition. Logarithmically transformed data of % inhibition of CTX-II levels at various dose levels along with corresponding plasma and synovial fluid drug levels were used for estimation of ED50 concentration using four parameter curve fit (GraphPad Prism 5 software).
Acute Rat Medial Meniscus Tear (MMT) Model of Osteoarthritis in Male Lewis Rats
The test compound was prepared in 1% Tween 80 in 0.5% hydroxypropyl methyl cellulose at desirable concentration for dosing (1, 3, 10, 30, 100 mg/kg). On the day of surgery (day 0), male LEW/HanTM Hsd rats were anesthetized in the anesthesia chamber using isoflurane (5%) with oxygen fixture. Anesthetized animals were placed on a temperature controlled surgery table. The skin over the medial aspect of the right femoro-tibial joint was clipped to remove the hair and surgically prepared with 70% alcohol wipe, followed by povidone-iodine and again by 70% alcohol wipe. The anaesthetized animals were placed on dorsal recumbence and transferred to a nose cone with 2-3% isoflurane and oxygen mixture to maintain anesthesia during surgery.
The animal's right leg was held in horizontal and flexion position supporting the knee joint depression with index fingernail. A horizontal incision of 1 cm length just near the knee joint depression was carried out. The fascia was cleaned by blunt dissection with straight scissor. The medial collateral ligament was located and cut with scalpel blade so that the two cut ends move in opposite direction (top and bottom). Through blunt dissection the medial meniscus, which is a shining body, was visualized and cut through the full thickness at its narrowest point to pull the cut meniscus back. The joint cavity was flushed with sterile saline and the skin incision was sutured with vicryl suture of size 3-0 (Ethilon, Catalogue no: NW2515). All procedures except medial meniscus tear were performed for sham surgery animals. Povidone iodine solution was applied on surgical site. Intactness of skin suture was checked daily, resutured where necessary. All animals were monitored daily for 6 days.
On day 6, the animals were dosed orally either twice (once in the morning and once in the evening) or once (in the evening) with vehicle or test compound at various dose levels. On day 7, one more dose of vehicle or test compound was administered. Three hours after last dosing, the animals were sacrificed with carbon dioxide exposure, synovial space of surgical knee joint was lavaged with 100 μL of filtered Dulbecco's phosphate buffered saline (1×) and synovial fluid was collected using a 1⁄2 cc insulin syringe. The synovial fluid was aspirated out and collected into pre-labeled EDTA tube (BD Biosciences, Catalogue No. 365974), and the samples were kept on ice. Blood was collected from heart puncture into sodium heparin or lithium heparin (100 IU/mL of 0.9% NaCl) vials for plasma drug concentration analysis. Plasma was separated and stored at −20° C. until analysis. Synovial fluid samples were spun down for 5 min at 16.1 relative centrifugal force. Synovial fluid was aliquoted into 96 well polypropylene round bottomed plates (Corning, catalogue no. 3799) and sealed with aluminum seal. Samples were stored at −20° C. Synovial fluid samples were analyzed for cartilaps (CTX-II) (Immunodiagnostic Systems INC-Nordic bioscience, serum preclinical cartilaps ELISA, Catalogue no AC-08F1) as per manufacturer's instructions. Drug concentration in synovial fluid and plasma was estimated by LCMS-MS using a validated method. Lower limit of detection is 1-5 ng/mL.
CTX-II levels in synovial fluid of MMT male Lewis rats treated with vehicle or test compound was subtracted from sham surgery control group synovial fluid levels. The average sham surgery group subtracted CTX-II levels in MMT vehicle treated group is considered as 100% response. Mean sham surgery group subtracted CTX-II levels in treated groups were used for calculation of % inhibition. Logarithmically transformed data of % inhibition of CTX-II levels at various dose levels along with corresponding plasma and synovial fluid drug levels were used for estimation of ED50 concentration using four parameter curve fit (GraphPad Prism 5 software).
