Matrix Metalloproteinase Inhibitor compounds This invention relates to novel chemical compounds, processes for their preparation, pharmaceutical formulations containing them and their use in therapy. The compounds of the invention are inhibitors of matrix metalloproteinase enzymes (MMPs). Matrix metalloproteinase enzymes play a major role in extracellular matrix component degradation and remodelling. Examples of MMPs include collagenase 1, 2 and 3, gelatinase A and B, stromelysin 1,2 and 3, matrilysin, macrophage metalloelastase, enamelysin and membrane type 1,2,3 and 4 MMP. The enzymes are secreted by connective tissue cells and inflammatory cells. Enzyme activation can not only initiate tissue damage but induce increased inflammatory cell infiltration into the tissue, leading to more enzyme production and subsequent tissue damage. For example, elastin fragments produced by MMP degradation are believed to stimulate inflammation by attracting macrophages to the site of MMP activity. Inhibition of MMPs provides a means for treating disease states wherein inappropriate metalloprotease activity results in degradation of connective tissue and inflammation.

Compounds of the invention may conveniently be administered in amounts of, for example, 0.01 to 100mg/kg body weight, preferably 0.1 to 25 mg/kg body weight, more preferably 0.3 to 5mg/kg body weight,. The compounds may be given more than once daily to be equivalent to the total daily dose. The precise dose will of course depend on the age and condition of the patient and the particular route of administration chosen and will ultimately be at the discretion of the attendant physician. No toxicological effects are expected when a compound according to the present invention is administered in the above mentioned dose range. Compounds of the invention may be tested for in vitro activity in accordance with the following assay: The fluorescent peptide substrate used in the MMP-12 assay is FAM-Gly-Pro-Leu-Gly- Leu-Phe-Ala-Arg-Lys(TAMRA), where FAM represents carboxyfluorescein, and TAMRA represents tetramethylrhodamine. MMP12 catalytic domain (residues 106-268) protein was expressed in E. coli in the form of insoluble inclusion bodies & stored in concentrated solution under denaturing conditions (8M guanidine hydrochloride). Enzyme was refolded into active form in situ by direct dilution into assay reactions. The 51 µL reactions are run in NUNC-brand black.square 384-well plates, each well containing 2 µM substrate, 20 nM enzyme, and 0.001-100 µM inhibitor, in 50 mM HEPES, pH 7.5,150 mM NaCI, 10 mM CaCI2,1 µM ZnAc, 0.6 mM CHAPS, and 2 % DMSO. Postitive control wells contain no inhibitor. Negative control wells are effected by either pre-dispensing the EDTA quench (see below) or by omiting enyme. Reactions are incubated at ambient temperature for 120 min, then quenched by the addition of 15µL of 100mM EDTA. Product formation in each well is quantified by measuring flourescense with a Molecular Devices Acquest. The excitation wavelength is set at 485 nM, and the emmision wavelenght is 530 nM. IC50 values were obtained by first calculating the percent inhibition (%l) at each inhibitor concentration (%l = 100*(1-(I-C2)/(C1-C2)), where C1 is the mean of the positive controls, and C2 is the mean of the negative controls), then fitting the %l vs. inhibitor concentration [I] data to: %I=A+((B-A)/(1+((C/[I]ˆD))), where A is the lower asymptote, B is the upper asymptote, C is the IC50 value, and D is the slope factor. When tested in this assay, compounds of Examples 1 to 12 had IC50s below 100 micromolar.
