Description

BICCLIC DERIVATIVES OF HYDROXAMIC ACID BACKGROUND OF THE INVENTION The present invention relates to bicyclic hydroxamic acid derivatives and to pharmaceutical compositions and methods of treatment. The compounds of the present invention are inhibitors of zinc metalloendopeptidases, especially those belonging to the subfamilies of the matrix metalloproteinases (also called MMPs or matrixmas) and reprolysin (also known as adamlisine) of the metcincins (Rawlings, et al., Methods in Enzvmoloqv, 248, 183-228 (1995) and Stocker, et al .. Protein Science, 4, 823-840 (1995)). The MMP subfamily of enzymes, currently contains seventeen members (MMP-1, MMP-2, MMP-3, MMP-7, MMP-8, MMP-9, MMP-10, MMP-11, MMP-12, MMP-13) , MMP-14, MMP-15, MMP-16, MMP-17, MMP-18, MMP-19 and MMP-20). Most MMPs are well known for their function of regulating the renewal of extracellular matrix proteins and, as such, play important roles in normal physiological processes such as reproduction, development and differentiation. In addition, MMPs are expressed in many pathological situations in which an abnormal renewal of connective tissue is occurring. For example, it has been shown that MMP-13, an enzyme with potent activity in the degradation of type II collagen (the main cartilage collagen), is overexpressed in cartilage with osteoarthritis (Mitchell, et al., J. Clin. Invest., 97, 764 (1996)). Other MMPs (MMP-2, MMP-3, MMP-8, MMP-9 and MMP-12) are also overexpressed in the cartilage with osteoarthritis and it is expected that the inhibition of some or all of these MMPs will slow down or block the loss Accelerated cartilage typical of joint diseases such as osteoarthritis and rheumatoid arthritis. Mammalian reprolysins are known as ADAM (A Dissintegrin And Metalloproteinase (a disintegrin and metalloproteinase) (Wolfberg, et al., J. Cell Biol., 131, 175-278 (1995)) and contain a disintegrin domain in addition to a domain similar to a metalloproteinase: Twenty-three different ADAMs have been identified to date, ADAM-17, also known as tumor necrosis factor-alpha (TACE), is ADAM-17 (TACE). responsible for the cleavage of tumor necrosis factor alpha (TNF-a, also known as cachectin) bound to cells.TNF-a is recognized to be involved in many infectious and autoimmune diseases (W. Friers, FEBS Letters, 285, 199 (1991)) In addition, it has been shown that TNF-a is the principal mediator of the inflammatory response seen in sepsis and septic shock (Spooner, et al., Clinical Immunology and Immunopatholoqy, 62 S1 1 (1992 ).) There are two forms of TNF-a, a prot Type II membrane eine with a relative molecular mass of 26,000 (26kD) and a soluble form of 17kD generated from the cell-bound protein by a specific proteolytic cleavage. The soluble 17 kD form of TNF-α is released by the cell and is associated with the deleterious effects of TNF-α. This form of TNF-a is also capable of acting in places far from the synthesis site. Thus, TACE inhibitors prevent the formation of soluble TNF-a and prevent the deleterious effects of soluble factor. The selected compounds of the invention are potent inhibitors of aggrecanase, an important enzyme in the degradation of cartilage aggrecan. Aggrecanase is also considered an ADAM. The loss of aggrecan from the cartilage matrix is an important factor in the progression of joint diseases such as osteoarthritis and rheumatoid arthritis, and it is expected that the inhibition of aggrecanase slows down or blocks the cartilage loss in these diseases . . Other ADAMs that have shown expression in pathological situations include ADAM TS-1 (Kuno, et al., J. Biol. Chem .. 272, 556-562 (1997)), and ADAM 10, 12 and 15 (Wu, et al .. Biochem Biophis, Res. Comm., 235, 437-442, (1997)). As knowledge of the expression, physiological substrates and disease association of ADAMs increases, the full significance of the inhibitory function of this class of enzymes will be appreciated. Diseases in which the inhibition of MMP and / or ADAM will provide a beneficial therapeutic effect include: arthritis (including osteoarthritis and rheumatoid arthritis), inflammatory bowel disease, Crohn's disease, emphysema, acute respiratory distress syndrome, asthma, chronic obstructive pulmonary disease, Alzheimer's disease, organ transplant toxicity, cachexia, allergic reactions, allergic contact hypersensitivity, cancer, tissue ulceration, restenosis, periodontal disease, epidermolysis bullosa, osteoporosis, lack of firmness in joint implants infections, atherosclerosis (including rupture of atherosclerotic plaques), aortic aneurysm (including abdominal aortic aneurysm and cerebral aortic aneurysm), congestive heart failure, myocardial infarction, stroke, cerebral ischaemia, head trauma, spinal cord injury, neurodegenerative disorders (acute and chronic), autoimmune diseases, Huntington's disease, Parkinson's disease, migraine, depression, peripheral neuropathy, pain, cerebral amyloid angiopathy, nootropic or cognitive augmentation, amyotrophic lateral sclerosis, multiple sclerosis, ocular angiogenesis, corneal injury, macular degeneration , abnormal healing of wounds, burns, diabetes, tumor invasion, tumor growth, tumor metastasis, scarring of the cornea, scleritis, AIDS, sepsis, septic shock and other diseases characterized by expression of metalloproteinases or ADAM. This invention also relates to a method for using the compounds of the invention in the treatment of the above diseases in mammals, especially in humans, and to pharmaceutical compositions useful therefor.
It is recognized that in different pathological situations different combinations of MMP and ADAM are expressed. In the case of individual diseases, such inhibitors may be preferred with specific selectivities by individual ADAM and / or MMPs. For example, rheumatoid arthritis is an inflammatory disease of the joints characterized by excessive levels of TNF and loss of constituents of the joint matrix. In this case, a compound that inhibits TACE and the loss of constituents of the joint matrix. In this case, a compound that inhibits TACE and aggrecanase, as well as MMPs such as MMP-13, may be the preferred therapy. In contrast, in a less inflammatory joint disease such as osteoarthritis, compounds that inhibit MMPs that degrade the matrix, such as MMP-13, but not TACE, may be preferred. The present inventors have also discovered that it is possible to design inhibitors with differential metalloproteinase activity. Specifically, for example, the inventors have been able to design molecules that selectively inhibit matrix metalloproteinase-13 (MMP-13) preferably with respect to MMP-1. Inhibitors of matrix metalloproteinases are known in the literature.

Stock solutions (10 mM) of inhibitors were prepared in dimethylsulfoxide and then diluted using the following scheme: 10 mM? 120 μM? 12 μM? 1.2 μM? 0.12 μM Twenty-five microliters of each concentration are then added, in triplicate, to the appropriate wells of a 96-well Microfluor plate. The final inhibitor concentration will be a 1: 4 dilution after the addition of enzyme and substrate. Positive controls (with enzyme, without inhibitor) are placed in wells D7-D12 and negative controls (without enzyme and without inhibitor) are arranged in wells D1-D6.

Control medium and IL-1 medium are added to the wells (450 μl) followed by the compound (50 μl) to start the assay. The plates are incubated at 37 ° C with a 5% CO2 atmosphere. When a release of 40-50% is reached (when the CPM value of the IL-1 medium is 4-5 times greater than that of the control medium) as assessed by liquid scintillation counting (LSC) of medium samples, the trial is finished (9-12 hours). The medium is removed from all wells and placed in scintillation tubes. The scintillation fluid is added and the radioactive counts (LSC) are acquired. To solubilize the cell layers, 500 μl of papain digestion buffer (0.2 M Tris, pH 7.0, 5 mM EDTA, 5 mM DTT and 1 mg / ml papain) is added to each well. The plates with digestion solution are incubated at 60 ° C overnight. The cell layer is removed from the plates the next day and placed in scintillation tubes. Then the scintillation liquid is added and the samples (LSC) are counted. The percentage of counts released from the total present in each well is determined. Averages of the triplicates are obtained by subtracting the background effect of the control of each well. The percent inhibition of the compound is based on IL-1 samples as 0% inhibition (100% total counts).
