MMP-13 inhibitors: A dysregulation of matrix metalloproteinase (MMP)-13 has been correlated with pathophysiological conditions like human carcinomas, rheumatoid arthritis, and osteoarthritis. This makes MMP-13 a suitable target for drug development. Since the family of MMPs comprises more than 23 different members in humans, a potential drug candidate should selectively and potently inhibit MMP-13 in order to avoid side effects resulting from a lack of selectivity. Additionally, the desired drug candidate should have a suitable pharmacokinetic profile. To realize the aim of developing potent and selective inhibitors of MMP-13 that are metabolically more stable, the chemical structure of lead compound 41, a potent and selective picomolar inhibitor of MMP-13 from an earlier work of KALININ et al., was extensively varied to access structurally diverse inhibitors. First, to avoid a possible O-dealkylation, the oxymethylene moiety of the lipophilic side chain of 41 was replaced with ethylene, vinylene, and acetylene moieties. These varied lipophilic side chains were accessed from starting materials like 1,4-diiodobenzene (43), 1-bromo-4-iodobenzene (80), and 4-iodoaniline (49) by employing reactions like C-C couplings, catalytic hydrogenation, semi-reduction of alkynes, diazotization, and desilylation. The respective fluorinated derivatives were obtained by reacting the various hydroxylated side chains with DAST. Starting from hydroxyproline derivative 57, amide 59, the central building block of the synthesis, was obtained by benzoylation, MITSUNOBU, and saponification reactions. Thus, hydroxamic acids I were obtained after SONOGASHIRA coupling reactions of the various side chains with aryl iodide 59 and aminolyses with hydroxylamine. In order to replace the carbonyl function of 41 with a sulfonyl moiety, which is more stable to hydrolysis, proline derivative 57 was transformed into diastereomeric sulfonamides II via sulfonylation, MITSUNOBU, and saponification reactions. Hence, sulfonamide-based hydroxamic acids 72 and 73 were afforded by C-C couplings with ether-based terminal alkyne 71 and aminolyses.
