Description

ACICLIC METALOPROTEASE INHIBITORS TECHNICAL FIELD This invention relates to compounds that are useful for treating diseases, conditions and disorders associated with unwanted metalloprotease activity.
BACKGROUND OF THE INVENTION Several structurally related metalloproteases [MP] carry out the degradation of structural proteins. Usually, these metalloproteinases act on the intercellular matrix and, in this way, they are related to the degradation and remodeling of the tissues. These proteins are called metalloproteases or MP. There are several different MP families, classified by sequence homology. Several known MP families are described in the art, as well as examples thereof. These MPs include matrix metalloproteases [MMP], zinc metalloproteases, many of the membrane-bound metalloproteases, TNF conversion enzymes, angiotensin converting enzymes (ACE), disintegrins, including ADAM (See Wolfsberg et al, 131 J. Cell Bio, 275-78, October 1995), and enkephalinases. Examples of MP include human skin fibroblast collagenase, human skin fibroblast gelatinase, human sputum collagenase, aggrecanase and gelatinase and human stromelysin. It is believed that collagenase, stromelysin, aggrecanase and related enzymes are important in mediating the symptomatology of several diseases. Potential therapeutic indications of MP inhibitors have been mentioned in written materials. See, for example, US patent. 5,506,242 (Ciba Geigy Corp); patent of E.U.A. 5,403,952 (Merck &Co); PCT published application WO 96/06074 (British Bio Tech Ltd); PCT publication WO 96/00214 (Ciba Geigy); WO 95/35275 (British Bio Tech Ltd); WO 95/35276 (British Bio Tech Ltd); WO 95/33731 (Hoffman-LaRoche); WO 95/33709 (Hoffman-LaRoche); WO 95/32944 (British Bio Tech Ltd); WO 95/26989 (Merck); WO 9529892 (DuPont Merck); WO 95/24921 (Ins.

Co. Ltd.); JP 7304770 (Kanebo Ltd.); and Bird et.al J. Med Chem vol. 37, pp. 158-69 (1994). Examples of potential therapeutic uses of MP inhibitors include rheumatoid arthritis (Mullins, D.E., et.al, Biochem. Biophvs. Acta. (1983) 695: 117-214); osteoarthritis (Henderson, B., et.al, Druqs of the Future (1990) 15: 495-508); the metastasis of tumor cells (ibid, Broadhurst, MJ, et.al, European patent application 276,436 (published in 1987), Reich, R., et.al, 48 Cancer Res. 3307-3312 (1988), and various ulcerations or ulcerative tissue conditions, for example, ulcerative conditions may originate in the cornea as a result of alkali burns or as a result of infection by Pseudomonas aeruginosa, Acanthamoeba, herpes simplex and vaccinia virus Other examples of conditions characterized by activity of unwanted metalloprotease include periodontal disease, bullous epidermolysis, fever, inflammation and scleritis (Cf. DeCicco et.al, WO 95 29892, published November 9, 1995.) In view of the intervention of said metalloproteases in various disease conditions Attempts have been made to prepare inhibitors for these enzymes Several of these inhibitors are described in written materials Examples include US Patent No. 5,183, 900, issued on February 2, 1993 to Galardy; the patent of E.U.A. No. 4,996,358, issued February 26, 1991 to Handa et.al; the patent of E.U.A. No. 4,771, 038, issued September 13, 1988 to Wolanin et.al; the patent of E.U.A.

Metalloprotease inhibitors are useful in the treatment of diseases caused, at least in part, by structural protein degradation. Although a variety of inhibitors have been prepared, there is a continuing need for potent matrix metalloprotease inhibitors, useful in the treatment of such diseases. Applicants have surprisingly discovered that the lactam-containing acyclic compounds of the present invention are potent metalloprotease inhibitors.
OBJECTIVES OF THE INVENTION Therefore, an object of the invention is to provide compounds useful in the treatment of conditions and diseases that are characterized by unwanted MP activity. It is also an object of the invention to provide potent inhibitors of metalloproteases. Another objective of the invention is to provide pharmaceutical compositions that include those inhibitors. It is also an object of the invention to provide a method of treatment for diseases related to metalloproteases.
BRIEF DESCRIPTION OF THE INVENTION The invention provides compounds that are useful as inhibitors of metalloproteases and that are effective in treating characterized conditions by the excessive activity of these enzymes. In particular, this invention relates to a compound having a structure according to formula (I) (i) where, A is S02Ar, COAr, CONHAr, PORAr, where Ar is a portion monocyclic or bicyclic aromatic or a monocyclic or bicyclic heteroaromatic portion, substituted or unsubstituted; Ri is alkyl or hydrogen; R2, R3 and R4 are each independently, chosen from hydrogen, alkyl, aryl, heteroaryl, arylalkyl, alkoxyalkyl, alkyl heterocycle, heterocyclealkyl, and these substituents may be substituted or unsubstituted; rings can be formed by R2 and R3, Ri and R2 or R3 and R4; X is a bond, an alkyl of (C-i-Cß) or a heteroatom chosen from O, N, NZ, S, SO or S02; Y is a bond, an alkyl of (C? -C6), CO, C02, CONH, or a heteroatom chosen from O, N, NZ, S, SO or S02; and Z is hydrogen, COR4, COOR4, CONHR4, R4, CSR4, CSNHR4 and S02R4. This structure also includes an optical isomer, diastereomer or enantiomer for the formula (I), or a pharmaceutically acceptable salt, or biohydrolyzable amide, ester or imide thereof, an optical isomer, diastereomer or enantiomer for the formula (I), or a pharmaceutically acceptable salt, or biohydrolyzable amide, ester or imide thereof. This structure also includes an optical isomer, diastereomer or enantiomer for the formula (I), or a pharmaceutically acceptable salt, or biohydrolyzable amide, ester or imide thereof. These compounds have the ability to inhibit at least one mammalian metalloprotease. Accordingly, in other aspects, the invention is directed to pharmaceutical compositions containing the compounds of the formula (I), and to methods for treating diseases characterized by unwanted metalloprotease activity using these compounds or the pharmaceutical compositions containing them.
Metalloproteases that are active at a particular unwanted site (e.g., an organ or certain cell types) can be identified by conjugating the compounds of the invention to an identification ligand, specific for a marker at that site, such as an antibody or fragment thereof or a receptor ligand. Methods of conjugation are known in the art. Also, the invention is directed to various methods that take advantage of the unique properties of these compounds. Thus, in another aspect, the invention is directed to the compounds of formula (I) conjugated to solid supports. These conjugates can be used as affinity reagents for the purification of a desired metalloprotease. In another aspect, the invention is directed to the compounds of the formula (I) conjugated in a tag. Since the compounds of the invention bind to at least one metalloprotease, the label can be used to detect the presence of relatively high levels of metalloprotease, preferably a cell culture in vivo or in vitro of a matrix metalloprotease. In addition, the compounds of the formula (I) can be conjugated to vehicles that allow the use of these compounds in immunization protocols to prepare antibodies specifically immunoreactive with the compounds of the invention. Typical conjugation methods are known in the art. Then, these antibodies are useful for therapy and to monitor the dosage of the inhibitors.

"Optical isomer", "stereoisomer" and "diastereomer", as they are referred to herein, have the normal meanings recognized in the art (Cf., Hawlev's Condensed Chemical Dictionary, 11th edition). The illustration of specific protected forms and other derivatives of compounds of the formula (I) is not intended to be limiting. The application of other useful protection groups, salt forms, etc., is within the skill of the person skilled in the art. As already defined and used herein, substituent groups can be substituted. That substitution can be with one or more substituents. Such substituents include those listed in C. Hansch and A.

According to the present invention, "mammalian metalloprotease" means any enzyme containing a metal and found in mammalian sources, which has the ability to catalyze the degradation of collagen, gelatin or proteoglycan under suitable test conditions. Suitable test conditions can be found, for example, in the U.S. patent. No. 4,743,587, which refers to the procedure of Cawston et.al, Anal. Biochem. (1979) 99: 340-345; Weingarten, H., et.al describe the use of a synthetic substrate in Biochem. Biophv. Res. Comm. (1984) 139: 1184-1187. Of course, it is possible to resort to any normal method to analyze the degradation of these structural proteins. The metalloprotease enzymes mentioned herein are all zinc-containing proteases that are similar in structure to, for example, human stromelysin or skin fibroblast collagenase. The ability of the candidate compounds to inhibit metalloprotease activity can, of course, be analyzed in the tests described above. The isolated metalloprotease enzymes can be used to confirm the inhibitory activity of the compounds of the invention, or raw extracts containing the scale of enzymes capable of degrading tissues can be used.
Compounds: The compounds of the invention are described in the Brief Description of the Invention. The preferred element A is S02Ar, where Ar is a monocyclic or bicyclic aromatic portion or a monocyclic or bicyclic heteroaromatic portion. This portion can be substituted or unsubstituted and can be carbocyclic or heterocyclic; the preferred heteroatoms include oxygen, sulfur and nitrogen, the most preferred being nitrogen. With nitrogen it is meant that the valence of nitrogen is preferred, so that if the preferred aromatic portion is benzimidazole, the nitrogen includes NH, to preserve the valence. The most preferred aromatic compounds include phenyl and pyridyl, even more preferably, phenyl. Element Ar includes substituted Ar; the substitution may be any number of substituents and at any position in the aromatic portion. The most preferred substituents are alkoxy, aryloxy, aryl, alkyl and halo. Where the Ar portion is monocyclic it is preferred that the substitution be in the 2 or 4 position as to the binding of the Ar to the sulfur, phosphorus, oxygen, nitrogen or coal of the carbonyl of the portion A. Ri includes alkyl, hydrogen, more preferably, hydrogen. R2, R3 and R4 are independently selected from hydrogen, alkyl, aryl, heteroaryl, arylalkyl, heterocycle, heterocycloalkyl, and these substituents can be substituted or unsubstituted. X includes a bond or a heteroatom chosen from O, N or S. Of course, the valence of nitrogen leaves room for = N = and -NZ-, and both are considered herein. Z includes COR4, COOR, CONHR and In addition, the rings can be formed by R2 and R3, to thereby form a "spirocyclic ring system", and R1 and R2 or R3 and R can form rings. Preferably, those rings are 5-7 elements in size.
Preparation of the compound: The hydroxamic compounds of the formula (I) can be prepared by the use of a variety of procedures. The general schemes include the following. The hydroxamic compounds of the formula (I) can be prepared by the use of a variety of procedures. The preferred methods in general for making the compounds include the following: A) Preparation of the NHA portion of the molecule and preparation of the hydroxamic acid: It is preferable that this portion of the synthesis proceed through different courses depending on the desired substituent. Where A is S02Ar, COAr, or PORAr, the synthesis proceeds through the use of amide chemistry. However, where A is CONHAr, it is preferable that the amino acid derivative react with the isocyanate ArNCO, as illustrated below. To make it easier, R1 and the portion of C (R2, R3, X-Y-R) is replaced with Q in this scheme: A = SO2Ar, COAr, PORAr NHAr A = CONHAr R 'is alkyl, alkoxy, hydrogen or any other portion with which an acyl halide or the like may then be made which can be used in the synthesis of hydroxamic acid. Then, the hydroxamic acid portion is prepared by normal methods, preferably by the preparation of an acyl halide and the hydroxylamine treatment.
B) Preparation of the "Q portion" rC (R2.R3, XY-R4) 1 Q [C (R2, R3, XY-R4)] can be added by a strong base, using for example metal hydrides with carbonyl compound, in an acidic carbon, which would be present in the alpha position for the carbonyl. Of course, the person skilled in the art would recognize that any free amine in an amino acid would require coverage for reasonable yields, as illustrated below. To make it easier, Ri is illustrated as H, and A is different from CONHAr. The person skilled in the art will be able to elaborate molecules with different substitution based on this illustrative scheme: M is a metal, preferably an alkali metal or alkaline earth metal R1 is an alkyl, benzyl, lower aryl or similarly saponified group X is preferably a halide or suitable leaving group, suitable for an acyl halide synthesis, more preferably is fluorine chlorine; or if the amidation is adequate it can be OH 1 AX, organic base, 2 (CF3CO) 2 ?, 3 ROH d-aspartic acid -R4 AHN 1 Hydrolysis of ester 2 Preparation of hydroxamic acid HO X "Y -R4 The compounds of this invention can also support base synthesis, such as in a column, or in a combination synthesis.
The supports for said synthetic methods are already in the commercial market and the methods for using them are known in general. The organic bases are used in the synthesis, almost always these are nitrogenous bases, and the preferred bases include piperidine, triethylamine (TEA), diisopropylamine (DIPEA), and the like. For illustrative purposes, two common materials and related general procedures are described: a) Chlorotrityl-polystyrene resin 1 pipepdine, 2 reactive coupling c c NHFmoc A = SC ^ Ar, COAr, PORAr, NHCONHAr TFA is trifluoroacetic acid or another suitable acid that will break the molecule from the resin, and does not react with the finished product. b) Wanq resin The compounds of the formula (I) are easily prepared from amino acids, amino acid derivatives and the like. Preferably, alpha-amino reacts with a compound having halo or a suitable leaving group. Of course, where the amino acid is not available, functionality can be reversed in the reagents, i.e., a leaving group of alphacarbonyl can be reacted with an amino group. Preferably, a primary amino compound under basic conditions displaces the halide or the leaving group. Amino acids include not only the twenty commonly occurring amino acids and their derivatives (for example, sarcosine, hydroxyproline, 2-aminobutyric acid, pipicolic acid and the like) and any of those d-amino acids, but also any alpha-amino acid. Many are known or available in the market, such as, from Sigma (St. Louis, MO) or Aldrich (Milwaukee, Wl). For those amino acids that are not available, variants of the amino acids can be made by any of the various methods known in the art. By the use of the following examples and the foregoing explanation, one skilled in the art can generate a variety of compounds in a similar manner, using the above scheme as a guide. These steps can be varied to increase the performance of the desired product. The person skilled in the art will also recognize that the judicious choice of reagents, solvents and temperatures is an important component in a successful synthesis. While determining the optimal conditions, etc. it is routine, it will be understood that to elaborate a variety of compounds these can be generated in a similar way by means of the guide of the previous scheme. The starting materials used in the preparation of the compounds of the invention are known, are manufactured by known methods or are commercially available as a starting material.
It is recognized that one skilled in the art of organic chemistry can easily perform normal manipulations of organic compounds without further direction; that is, it is within the scope and practice of the expert to carry out such manipulations. These include, but are not limited to, reduction of carbonyl compounds to their corresponding alcohols, oxidations of hydroxyl and similiar, acylations, aromatic substitutions, both electrophilic and nucleophilic, etherification, esterification and saponification and the like. Examples of these manipulations are described in standard texts, such as March, Advanced Orqanic Chemistrv, (Wiley), Carey and Sundberg, Advanced Orqanic Chemistry (Vol. 2). The skilled artisan will readily appreciate that certain reactions are best performed when hides or protects another functionality in the molecule, thereby avoiding any unwanted side reactions and / or increasing the reaction yield. Often, the person skilled in the art uses protective groups to achieve the increase of said yields or to avoid unwanted reactions. These reactions are found in written material and are also within the reach of the person skilled in the art. Examples of many of these manipulations can be found, for example, in T. Greene, Protectinq Groups in Orqanic Synthesis. Of course, amino acids used as starting materials with reactive side chains are preferably blocked to avoid unwanted side reactions.
The compounds of the invention may have one or more chiral centers. As a result, an optical isomer, including diastereomer and enantiomer, can be selectively prepared on others; for example, by means of chiral starting materials, catalysts or solvents, or stereoisomers or optical isomers can be prepared, including diastereomers and enantiomers (a racemic mixture). Since the compounds of the invention can exist as racemic mixtures, mixtures of optical isomers, including diastereomers and enantiomers or stereoisomers can be separated using known methods, such as for example chiral salts, chiral chromatography and the like. Furthermore, it is recognized that an optical isomer, including diastereomer and enantiomer, or stereoisomer, may have favorable properties over others. Thus, when describing and claiming the invention, when describing a racemic mixture, it is clearly observed that optical isomers are also described and claimed, including diastereomers and enantiomers, or stereoisomers basically without the others.
Methods of use Metalloproteinases (MP) found in the body function, in part, by degrading the extracellular matrix, which comprises proteins and extracellular glycoproteins. These proteins and glycoproteins play an important role in maintaining the size, shape, structure and stability of the tissue in the body. Metalloprotease inhibitors are useful in the treatment of diseases caused, at least in part, by the degradation of these proteins. It is known that MPs are intimately related to tissue remodeling. As a result of this activity, it has been mentioned that they are active in many disorders that include either: tissue degradation; including degenerative diseases, such as arthritis, multiple sclerosis and the like, metastasis or mobility of tissues in the body: tissue remodeling, including fibrotic disease, scarring, benign hyperplasia and the like. The compounds of the present invention treat diseases, disorders and / or undesired conditions that are characterized by an undesired or elevated activity of that class of proteases. For example, the compounds can be used to inhibit proteases that: destroy structural proteins (ie, proteins that maintain the stability and structure of tissues); interfere with intracellular / intracellular signaling, including those involved in cytokine regulation and / or cytokine processing and / or inflammation, tissue degradation and other diseases [Mohler KM, et.al, Nature 370 (1994) 218-220; Gearing AJH, et.al, Nature 370 (1994) 555-557; McGeehan GM, et.al, Nature 370 (1994) 558-561], and / or facilitate unwanted processes in the subject being treated, for example, the processes of sperm maturation, ovule fertilization and the like.
As used herein, a "disorder related to MP "or" MP-related disease "is that which has to do with an unwanted or elevated MP activity in the biological manifestation of the disease or disorder, in the biological cascade leading to the disorder, or as a symptom of the disorder. This "intervention" of MP includes: the activity of unwanted or elevated MP as a "cause" of the disorder or biological manifestation, whether the activity has been genetically elevated, by infection, by autoimmunity, trauma, biomechanical causes, quality of life [eg, obesity] or for some other cause, MP as part of the observable manifestation of the disease or disorder, that is, the disease or disorder can be measured in terms of the increase in MP activity, or from a certain point Clinically, unwanted or elevated MP levels indicate the disease MPs do not need to be the "hallmark" of the disease or disorder, unwanted or elevated MP activity is part of the biochemical cascade or cell which results or relates to the disease or disorder. In this regard, the inhibition of MP activity disrupts the cascade and thus controls the disease. Fortunately, many MPs are not evenly distributed in the body. Therefore, the distribution of MP expressed in various tissues is often specific for these tissues. For example, the distribution of metalloproteases involved in the degradation of joint tissues is not the same as the distribution of metalloproteases found in other tissues. Accordingly, although not essential for activity or efficacy, certain disorders are preferably treated with compounds that act on specific MPs found in the affected tissues or regions of the body. For example, a compound that exhibits a greater degree of affinity and inhibition for MP found in the joints (e.g., chondrocytes) would be preferred than other compounds that are less specific for the treatment of a disease found there. In addition, certain inhibitors have greater bioavailability than others for certain tissues, and this judicious choice of inhibitor, with the selectivity described above provides a specific treatment of the disorder, disease or unwanted condition. For example, the compounds of this invention vary in their ability to penetrate the central nervous system. In this way, the compounds can be selected to produce mediated effects through MP found specifically outside the central nervous system. The determination of the specificity of an MP inhibitor of a certain MP is within the ability of the expert in that field. Proper test conditions can be found in written material. There is a specific knowledge of the tests for stromelysin and collagenase. For example, the patent of E.U.A. No. 4,743,587 refers to the procedure of Cawston et.al, Anal Biochem (1979) 99: 340-345. Weingarten, H., et.al describe the use of a synthetic substrate in a test in Biochem Biophv Res Comm (1984) 139: 1184-1187. Of course, any standard method for analyzing the degradation of structural proteins by MP can be used. The ability of the compounds of the invention to inhibit the activity of metalloproteases, of course, can be proven in the tests found in the written material or variations thereof. The isolated metalloprotease enzymes can be used to confirm the inhibitory activity of the compounds of the invention, or crude extracts containing the scale of enzymes that can degrade the tissues can be used. As a result of the inhibitory effect of MP of the compounds of the invention, these are also useful in the treatment of the following disorders by virtue of their metalloprotease activity. The compounds of this invention are also useful for prophylactic or acute treatment. They are administered in the way that experts in the fields of medicine or pharmacology wish. It is immediately apparent to the person skilled in the art that the preferred routes of administration will depend on the state of the disease being treated, as well as on the chosen dosage form. Preferred routes for systemic administration include peroral and parenteral administration. However, one skilled in the art will readily appreciate the convenience of administering the MP inhibitor directly to the affected area for many disorders. For example, it may be convenient to administer MP inhibitors directly to the area of the disease or condition, such as in an area affected by surgical trauma (eg, angioplasty), an area affected by scarring or burns (eg, topical to the skin). ). Since bone remodeling is related to MP, the compounds of the invention are useful to prevent prosthesis from loosening. In the art it is known that with the passage of time the prostheses become loose, become painful and can cause another injury to the bone, which would require a replacement. The need for replacement of such prostheses includes such as in, joint replacements (for example, hip, knee and shoulder replacements), dentures, including dentures, bridges and prostheses secured to the maxilla and / or mandible. MP are also active in the remodeling of the cardiovascular system (for example, in congestive heart failure). It has been suggested that one of the reasons why angioplasty has a higher-than-expected rate of long-term insufficiency (reobstruction with time) is because MP activity is not desired or is high in response to what the body can do. recognize as "injury" to the base membrane of the blood vessel. Thus, regulation of MP activity in indications such as dilated cardiomyopathy, congestive heart failure, atherosclerosis, plaque rupture, reperfusion injury, ischemia, chronic obstructive pulmonary disease, restenosis by angioplasty and aortic aneurysm may increase the success of long term of any other treatment, or it can be a treatment in itself. In the care of the skin, the MPs participate in the remodeling or "renewal" of the skin. As a result, MP regulation improves the treatment of skin conditions, including but not limited to, repair, regulation and prevention of wrinkles, as well as repair of skin damage caused by ultraviolet rays. Such treatment includes prophylactic treatment or treatment before the physiological manifestations are evident. For example, MP can be applied as a pre-exposure treatment to prevent damage by ultraviolet rays and / or during or after exposure to prevent or minimize post-exposure damage. In addition, MPs are involved in disorders and skin diseases related to abnormal tissues resulting from an abnormal manifestation, including metalloprotease activity, such as epidermolysis bullosa, psoriasis, scleroderma and atopic dermatitis. The compounds of the invention are also useful for treating the consequences of "normal" skin injuries, including scarring or "shrinkage" of tissues, for example, after burns. Inhibition of MP is also useful in skin-related surgical procedures to prevent scar formation and the promotion of normal tissue growth, including in those applications reattaching the limb and refractory surgery (either by laser or incision ). In addition, MPs are related to disorders that include irregular remodeling of other tissues, such as bone, for example, in otosclerosis and / or osteoporosis, or for specific organs, such as liver cirrhosis and pulmonary fibrotic disease. Similarly, in diseases such as multiple sclerosis, PM can intervene in the irregular modeling of the blood-brain barrier and / or nerve tissue myelin sheaths. In this way, the regulation of MP activity can be used as a strategy in the treatment, prevention and control of these diseases. Likewise, it is thought that MPs are involved in many infections, including cytomegalovirus.; retinitis [CMV]; HIV and the resulting syndrome, AIDS. MP can also intervene in extravascularization, where the surrounding tissue needs to be degraded to allow new blood vessels, as in angiofibrone and hemangioma. Since MPs degrade the extracellular matrix, it is observed that inhibitors of these enzymes can be used as agents for birth control, for example to prevent ovulation, to prevent the penetration of sperm into and through the extracellular environment of the ovule, as well as the implantation of the fertilized ovum and to prevent sperm maturation. In addition, it is also observed that they are useful to prevent or stop premature labor and delivery. Since MPs are involved in the inflammatory response and in cytokine processing, the compounds are also useful as anti-inflammatories for use in diseases in which inflammation prevails, including, inflammatory bowel disease, Crohn's disease, ulcerative colitis, pancreatitis, diverticulitis, asthma or related lung disease, rheumatoid arthritis, gout and Reiter's syndrome.
When autoimmunity is the cause of the disorder, the immunological response often triggers the activity of MP and cytokine. The regulation of MPs in the treatment of said autoimmune disorders is a useful treatment strategy. Accordingly, PM inhibitors can be used for the treatment of disorders including, lupus erimatosus, ankylosing spondylitis and autoimmune keratitis. Sometimes side effects of autoimmune therapy result in exacerbation of other conditions mediated by MP; inhibitory therapy of MP is also effective here, for example, in fibrosis induced by autoimmune therapy. In addition, other fibrotic diseases lend themselves to this type of therapy, including lung disease, bronchitis, emphysema, cystic fibrosis, acute respiratory fatigue syndrome (especially the acute phase response). When MPs intervene in the unwanted degradation of tissue by exogenous agents, they can be treated with MP inhibitors. For example, they are effective as an antidote for rattlesnake bite, as antivesics, in the treatment of allergic inflammations, septicemia and shock. In addition, they are useful as antiparasitic (e.g., in malaria) and anti-infectious. For example, they are believed to be useful in the treatment or prevention of viral infections, including infection that would result in herpes, "cold" (e.g., rhinoviral infection), meningitis, hepatitis, HIV infection and AIDS.
It is also believed that MP inhibitors are useful in the treatment of Alzheimer's disease, amyotrophic lateral sclerosis (ALS), muscular dystrophy, complications derived from or that originate from diabetes, especially those that include loss of tissue viability. , coagulation, Graft disease vs. Host, leukemia, cachexia, anorexia, proteinuria and perhaps the regulation of hair growth. For some diseases, conditions or disorders, the inhibition of MP is contemplated as a preferred method of treatment. Said diseases, conditions or disorders include arthritis (including osteoarthritis and rheumatoid arthritis), cancer (especially the prevention or control of growth and tumor metastasis), eye disorders (especially corneal ulceration, lack of corneal healing, macular degeneration and pterygium); and diseases of the gums (especially periodontal disease and gingivitis). Preferred compounds for, but not limited to the treatment of arthritis (including osteoarthritis and rheumatoid arthritis) are those compounds that are selective for metalloproteases and disintegrin metalloproteases. Preferred compounds for, but not limited to the treatment of cancer (especially the prevention or combating of growth and tumor metastasis) are those compounds that preferably inhibit gelatinases or type IV collagenases. Preferred compounds for, but not limited to the treatment of ocular disorders (especially corneal ulceration, lack of healing of the cornea, macular degeneration and pterygium) are those compounds that broadly inhibit metalloproteases. Preferably, these compounds are administered topically, more preferably in a drop or gel. Preferred compounds for, but not limited to the treatment of gum diseases (especially periodontal disease and gingivitis) are those compounds that preferably inhibit collagenases.
Compositions: The compositions of the invention comprise: (a) a safe and effective amount of a compound of the formula (I); and (b) a pharmaceutically acceptable carrier. As already mentioned, it is known that numerous diseases are mediated by excessive or unwanted metalloprotease activity. These include tumor metastasis, osteoarthritis, rheumatoid arthritis, inflammations of the skin, ulcerations, particularly of the cornea, reactions to infections, periodontitis and the like. In this manner, the compounds of the invention are useful in therapy with respect to conditions related to this undesired activity. Therefore, the compounds of the invention can be formulated into pharmaceutical compositions useful for the treatment or prophylaxis of these conditions.

Preferably, the compositions of this invention are provided in unit dosage form. As used herein, a "unit dose form" is a composition of this invention that contains an amount of a compound of the formula (I) that is suitable for administration to an animal, preferably a mammal, in a single dose, according to the proper medical practice. These compositions preferably contain from about 5 mg (milligrams) to about 1000 mg, more preferably from about 10 mg to about 50 mg, still more preferably from about 10 mg to about 300 mg of a compound of the formula (I) . The compositions of this invention can be in any variety of suitable forms (for example) for oral, rectal, topical, nasal, ocular or parenteral administration. Depending on the specific route of administration desired, a variety of pharmaceutically acceptable carriers well known in the art may be employed. These include liquid or solid fillers, diluents, hydrotropes, surfactants and encapsulating substances. Optional pharmaceutically active materials may be included, which do not substantially interfere with the inhibitory activity of the compound of the formula (I). The amount of vehicle employed together with the compound of the formula (I) is sufficient to provide a practical amount of material for administration per unit dose of the compound of the formula (I). Techniques and compositions for making dosage forms useful in the methods of this invention are described in the following references, all incorporated herein by reference: Modern Pharmaceutics, Chapters 9 and 10 (Banker &Rhodes, editors, 1979); Lieberman et.al, Pharmaceutical Dosaqe Forms: Tablets (1981); and Ansel, Introduction to Pharmaceutical Dosaqe Forms 2nd. edition (1976). In addition to the present compound, the compositions of the present invention contain a pharmaceutically acceptable carrier. The term "pharmaceutically acceptable vehicle"as used herein, means one or more compatible solid or liquid filling or encapsulating substances or diluents that are suitable for administration to an animal, preferably a mammal. The term "compatible" as used herein, means that the components of the composition can be mixed with the present compound and with each other, such that there is no interaction that could substantially reduce the pharmaceutical efficacy of the composition under normal situations of use. Of course, pharmaceutically acceptable carriers should have sufficiently high purity and toxicity low enough to make them suitable for administration to the animal, preferably a mammal under treatment. Some examples of substances that can serve as pharmaceutically acceptable carriers or components thereof are sugars, such as lactose, glucose and sucrose.; starches such as corn starch and potato starch; cellulose and its derivatives, such as sodium carboxymethyl cellulose, ethyl cellulose and methyl cellulose; powdered tragacanth; malt; jelly; talcum powder; solid lubricants, such as stearic acid and magnesium stearate; calcium sulfate; vegetable oils, such as peanut oil, cottonseed oil, sesame oil, olive oil, corn oil and theobroma oil; polyols such as propylene glycol, glycerin, sorbitol, mannitol and polyethylene glycol; alginic acid; emulsifiers such as TWEENS®; wetting agents such as sodium laurisulfate; coloring agents; flavoring agents; tabletting agents, stabilizers; antioxidants; conservatives; water without pyrogens; isotonic saline solution and phosphate buffer solutions.

If the present compound is to be injected, the preferred pharmaceutically acceptable carrier is sterile physiological saline with a blood-compatible suspension agent, whose pH has been adjusted to about 7.4. Various oral dosage forms can be employed, including solid forms such as tablets, capsules, granules and powders. These oral forms comprise a safe and effective amount, usually at least about 5% and preferably about 25% to about 50%, of the compound of the formula (I). The tablets can be compressed, comminuted, enteric-coated, sugar-coated, film-coated or multiple-compressed, containing binders, lubricants, diluents, disintegrating agents, coloring agents, flavoring agents, flow-inducing agents and lubricants. appropriate fusion. The liquid oral dosage forms include aqueous solutions, emulsions, suspensions, solutions and / or suspensions reconstituted from non-effervescent granules and effervescent preparations reconstituted from effervescent granules, containing suitable solvents, preservatives, emulsifying agents, suspending agents, diluents, sweeteners, fusion agents, coloring agents and flavoring agents. The pharmaceutically acceptable carrier suitable for the preparation of unit dosage forms for peroral administration is well known in the art. Almost always, the tablets comprise, as inert diluents, pharmaceutically compatible and conventional adjuvants, such as calcium carbonate, sodium carbonate, mannitol, lactose and cellulose; binders such as starch, gelatin and sucrose; disintegrants such as starch; alginic acid and croscarmellose; lubricants such as magnesium stearate, stearic acid and talc. Slip agents such as silicon dioxide can be used to improve the flow characteristics of the powder mixture. Coloring agents such as FD &C dyes can be added to improve appearance. Sweetening and flavoring agents such as aspartame, saccharin, menthol, peppermint and fruit flavors are also useful adjuvants for chewable tablets. Almost always, the capsules include one or more of the solid diluents already described. The selection of the components of the vehicle depends on secondary considerations such as taste, cost and shelf stability, which are not decisive for the purposes of the present invention and which one skilled in the art can elaborate with ease. Peroral compositions also include liquid solutions, emulsions, suspensions and the like. Pharmaceutically acceptable carriers suitable for the preparation of such compositions are well known in the art. Typical vehicle components for syrups, elixirs, emulsions and suspensions include ethanol, glycerol, propylene glycol, polyethylene glycol, liquid sucrose, sorbitol and water. For a suspension, typical suspending agents include methylcellulose, carboxymethylcellulose, AVICEL RC-591, tragacanth and sodium alginate.; typical wetting agents include lecithin and polysorbate 80; and typical preservatives include methylparaben and sodium benzoate. Peroral liquid compositions may also contain one or more components such as the sweeteners, flavoring agents and colorants described above. Said compositions can also be coated by conventional methods, usually with pH or time sensitive coatings, such that the present compound is released into the gastrointestinal tract, close to the desired topical application, or repeatedly to prolong the desired action. Almost always, said dosage forms include, but are not limited to, one or more of the following: cellulose acetate phthalate, polyvinylacetate phthalate, dihydroxypropylmethylcellulose phthalate, ethylcellulose, Eudragit coatings, waxes and lacquer. The compositions of the present invention may optionally include other drug actives. Other compositions useful for achieving systemic delivery of the present compounds include sublingual, buccal and nasal dosage forms. Almost always said compositions comprise one or more soluble filler substances such as sucrose, sorbitol and mannitol; and binders such as acacia, microcrystalline cellulose, carboxymethylcellulose and hydroxypropylmethylcellulose. They are also described above and may include slip agents, lubricants, sweeteners, colorants, antioxidants and flavoring agents. The compositions of the present invention can also be administered topically to a subject, e.g., by direct placement or dispersion of the composition on the epidermal or epithelial tissue of the subject, or transdermally by means of a "patch". Such compositions include, for example, lotions, creams, solutions, gels and solids. Preferably these topical compositions comprise a safe and effective amount, usually at least about 0.1% and preferably about 1% to about 5%, of the compound of the formula (I). Vehicles suitable for topical administration preferably remain in place on the skin as a continuous film, and are resistant to removal by transpiration or immersion in water. In general, the carrier is of an organic nature and the compound of formula (I) can be dispersed or dissolved therein. The vehicle may include emollients, emulsifiers, thickening agents and pharmaceutically acceptable solvents, and the like.
Methods of administration This invention also provides methods for treating or preventing disorders associated with excessive or undesired activity of the metalloprotease in an animal, preferably a mammal, by administering a safe and effective amount of a compound of the formula (I) to said mammal. subject. As used herein, the phrase "a disorder associated with excessive or unwanted metalloprotease activity" is any disorder characterized by protein degradation. The methods of the invention are useful in the treatment of disorders, such as, for example, osteoarthritis, periodontitis, corneal ulceration, tumor invasion and rheumatoid arthritis. The compounds and compositions of the formula (I) of this invention can be administered topically or systemically. Systemic application includes any method for introducing a compound of formula (I) into body tissues, eg, intra-articular administration (especially in the treatment of rheumatoid arthritis), intrathecal, epidural, intramuscular, transdermal, intravenous, intraperitoneal , subcutaneous, sublingual, rectal and oral. Preferably, the compounds of the formula (I) of the present invention are administered orally. The specific dose of inhibitor to be administered, the duration of treatment and treatment whether topical or systemic are independent. The dosage and treatment regimen will also depend on factors such as the specific compound of the formula (I) that is used, the indication of the treatment, the ability of the compound of the formula (I) to reach minimal inhibitory concentrations at the metalloprotease site. which will be inhibited, the subject's personal attributes (such as weight), cooperation with the treatment regimen and the presence and severity of any side effects of the treatment. Almost always, for a human adult (weighing about 70 kilograms), about 5 mg to about 3,000 mg, more preferably about 5 mg to about 1,000 mg, more preferably about 10 mg to about 300 mg of the compound of the formula (I) per day for systemic administration. It is understood that these dosing scales are by way of example only and that daily administration can be adjusted depending on the factors mentioned above. A preferred method of administration for the treatment of rheumatoid arthritis is oral or parenteral by intra-articular injection. As is known and practiced in the art, all formulations for parenteral administration must be sterile. For mammals, especially humans (assuming an approximate body weight of 70 kilograms), individual doses of about 10 mg to about 1000 mg are preferred. A preferred method of systemic administration is oral. Individual doses of about 10 mg to about 1000 mg, preferably about 10 mg to about 300 mg, are preferred. It is possible to resort to topical administration to deliver the compound of the formula (I) systemically or to treat a subject locally. The amounts of the compound of the formula (I) that will be administered topically depend on factors such as skin sensitivity, type and location of the tissue to be treated; the composition and the vehicle (if any) to be administered; the compound of the specific formula (I) to be administered, as well as the particular disorder to be treated and the degree to which the systemic effects are desired (different from the local ones).
The inhibitors of the invention can be directed to specific sites where the metalloprotease is accumulated by selection ligands. For example, to target the inhibitors to the metalloprotease contained in a tumor, the inhibitor is conjugated to an antibody or fragment thereof that is immunoreactive with a tumor marker, as is commonly understood in the preparation of immunotoxins in general. The selection ligand may also be a suitable ligand for a receptor that is in the tumor. Any selection ligand that specifically reacts with a marker for the target tissue can be used. The methods for coupling the compound of the invention to the selection ligand are already known and are similar to those described below for coupling to the vehicle. The conjugates are formulated and administered as described above. For localized conditions, topical administration is preferred. For example, to treat ulcerated cornea, direct application to the affected eye can use a formulation such as eye drops or spray. For the treatment of the cornea, the compounds of the invention can also be formulated as gels, drops or ointments, or they can be incorporated into collagen or a hydrophilic polymer shell. The materials can also be inserted as a contact lens or reservoir, or as a subconjunctive formulation. For the treatment of inflammations of the skin, the compound is applied locally and topically, in gel, paste, ointment or ointment. Therefore, the mode of treatment reflects the nature of the condition, and suitable formulations for any selected route are available in the art. Of course, in all of the foregoing, the compounds of the invention may be administered alone or as mixtures, and the compositions may additionally include additional drugs or excipients, as appropriate for the indication. Some of the compounds of the invention also inhibit bacterial metalloproteases, although generally at a level lower than that shown by mammalian metalloproteases. Some bacterial metalloproteases appear to be less dependent on the stereochemistry of the inhibitor, while substantial differences are found between the diastereomers in their ability to inactivate mammalian proteases. In this way, this pattern of activity can be used to distinguish between mammalian and bacterial enzymes.
Preparation and use of antibodies The compounds of the invention can also be used in immunization protocols to obtain immunospecific antisera for the compounds of the invention. Since the compounds of the invention are relatively small, they are conveniently coupled to antigenically neutral vehicles, such as the limpet hemocyanin (KLH) that is commonly used or whey albumin vehicles. For those compounds of the invention having a carboxyl functionality, coupling to the carrier could be performed by methods generally known in the art. For example, the carboxyl residue can be reduced to an aldehyde and coupled to vehicle via reaction with side chain amino groups in protein-based vehicles, optionally followed by reduction of the imino bond formed. The carboxyl residue can also be reacted with side chain amino groups by condensation agents, such as dicyclohexylcarbodiimide or other carbodiimide dehydration agents. The linker compounds can also be used to effect the coupling; Pierce Chemical Company, Rockford, Ill provides the homobifunctional and heterobifunctional linkers. The resulting immunogenic complex can then be injected into suitable mammals, such as mice, rabbits and the like. Suitable protocols include the repeated injection of the immunogen in the presence of adjuvants according to a program that promotes the production of antibodies in the serum. Immune serum concentrations can be easily measured using immunoassay methods, now common in the art, using the compounds of the invention as antigens. The obtained antisera can be used directly or monoclonal antibodies can be obtained by culturing lymphocytes from the peripheral blood or spleen of the immunized animal and immortalizing the antibody producing cells, followed by identification of the appropriate antibody producers by normal immunoassay techniques.
Then, polyclonal or monoclonal preparations are useful for monitoring therapy regimens or prophylaxis relative to the compounds of the invention. Suitable samples, such as those derived from blood, serum, urine or saliva can be tested to verify the presence of the inhibitor administered on several occasions during the treatment protocol by normal immunoassay techniques employing the antibody preparations of the invention. The compounds of the invention can also be coupled to labels such as scintigraphic labels, e.g., technetium 99 or 1-131, through normal coupling methods. The labeled compounds are administered to subjects to determine sites of excessive amounts of one or more metalloproteases in vivo. The ability of the inhibitors to selectively bind to metalloproteases to capture the distribution of these enzymes in situ is then exploited. The techniques can also be employed in histological procedures and the labeled compounds of the invention can be used in competitive immunoassays. The following non-limiting examples illustrate the compounds, compositions and uses of the present invention.
EXAMPLES The compounds are analyzed using 1 H and 13 C NMR, elemental analysis, mass spectrum and / or IR spectrum, as appropriate.
Inert solvents are almost always used, preferably in dry form. For example, tetrahydrofuran (THF) is distilled from sodium and benzophenone, diisopropylamine is distilled from calcium hydride and the rest of the solvents are purchased to the appropriate degree. Chromatography is performed on silica gel (70-230 mesh, Aldrich) or (230-400 mesh, Merck) as appropriate. Thin-layer chromatography (TLC) analysis is performed on glass-mounted silica gel plates (200-200 mesh; Baker) and visualized with UV or 5% phosphomolybdic acid in EtOH.

To this was added Na- (Fmoc)) - Nß- (Dde) -diaminopropionic acid (3.1 g, 6.3 mmol) followed by triethylamine (0.9 ml, 6.3 mmol) and 1- (3-dimethylaminopropyl) -3-ethylcarbodiimide hydrochloride. (1.2 g, 6.3 mmol). The mixture was stirred until all the components were dissolved, at which point hydroxybenzotriazole (0.1 g, 0.63 mmol) was added and the suspension was stirred for 23 hours. The resin was filtered and washed with various portions of dichloromethane and methanol. The resin was dried under vacuum for 16 hours. The production and the new load values were determined by separating a small amount of the derived resin (0.036 g) with 95% TFA / H20. Production 10 mg (95%), MS m / z 491 [M + H] +. The new load value was determined as 0.601 mmoles / g. The previously loaded resin was transferred to a 96-well reaction block of the Advanced Chemtech 496 MOS robot. Functionalized resin (0.050 g, 0.03 mmol) was added to each of the 80 wells. All subsequent procedures were developed in each of the 80 wells.
Deprotection with Fmoc: The resin was suspended in N, N-dimethylformamide (0.5 ml) and a 20% solution of piperidine in DMF (1.5 ml) was added thereto. The reaction was stirred for 20 minutes and subsequently the resin was filtered. This protocol was repeated once again. After the final filtration, the resin was washed with DMF (2x2 ml). The resin was again washed twice with DCE (1x2 ml) and MTH (1x2 ml) in an alternating manner.
Formation of alpha sulfonamide (Ri): The resin was suspended in THF (0.5 ml) and to this was added a 0.5 M solution of the sulfonyl chloride in THF (1.0 ml) (see table 1) followed by a 1.0 M solution of DiPEA in THF (0.5 ml). The reaction was stirred for 20 hours and then filtered. The resin was washed with DCE (2x2 ml) followed by methanol (2x2 ml) and DCE (2x2 ml) in an alternating manner.
Deprotection with Dde: The resin was treated with 2% hydrazine in DMF (1.5 ml). The resin was stirred for 25 minutes and then filtered. Following the final filtration, the resin was washed with DMF (2x2 ml). The resin was subsequently washed twice each with DCE (1x2 ml) and MTH (1x2 ml) in an alternating manner.
Formation of Beta sulfonamide (R?): The resin was suspended in THF (0.5 ml) and a 0.5 M solution of sulfonyl chloride in THF (1.0 ml) was added (see table 1) followed by a 1.0 M solution. of DiPEA in THF (0.5 ml). The reaction was stirred 20 hours and then filtered. The resin was washed with DCE (2x2 ml) followed by methanol (2x2 ml) and DCE (2x2 ml) in an alternating manner.
Hydroxylamine separation: Hydroxylamine hydrochloride (9.2 g) was dissolved in methanol (50 ml) by heating. In a separate flask, potassium hydroxide (10.3 g) was dissolved in hot methanol (25 ml). Both solutions were allowed to cool to almost room temperature before the KOH solution was slowly added to the hydroxylamine solution. The exothermic reaction produced a white precipitate which was removed by filtration. The filtrate was collected and stored in an ice box for 72 hours. After 72 hours, the filtrate was again filtered, placed in an amber container and stored in the refrigerator. The resin was suspended in THF (1.25 ml) and the separation mixture (0.250 ml) was added thereto. The reaction was allowed to stir for 72 hours at which time the resin was filtered and the filtrate was collected. The resin was washed once with methanol (0.5 ml) and this wash was added to the filtrate. A solution of 1N HCl (0.170 ml) was added to the filtrate and all volatiles were removed by evaporation.
