Discovery of CGS 27023A, a Non-Peptidic, Potent, and Orally Active Stromelysin Inhibitor That Blocks Cartilage Degradation in Rabbits
摘要:
Structure-activity relationships of a lead hydroxamic acid inhibitor of recombinant human stromelysin were systematically defined by taking advantage of a concise synthesis that allowed diverse functionality to be explored at each position in a template. An ex vivo rat model and an in vivo rabbit model of stromelysin-induced cartilage degradation were used to further optimize these analogs for oral activity and duration of action. The culmination of these modifications resulted in CGS 27023A, a potent, orally active stromelysin inhibitor that blocks the erosion of cartilage matrix.

Non-peptidic inhibitors of procollagen C-proteinase (PCP) were designed from substrate leads. Compounds were optimized for potency and selectivity, with N-substituted aryl sulfonamide hydroxamates having the best combination of these properties. Compounds 89 and 60 have IC50 values of 10 and 80 nM, respectively, against PCP; excellent selectivity over MMP's 1, 2, and 9; and activity in cell-based collagen deposition assays.
