Synthesis and biological evaluation of 3-[4-(amino/methylsulfonyl)phenyl]methylene-indolin-2-one derivatives as novel COX-1/2 and 5-LOX inhibitors
摘要:
Fourteen new 3-[4-(amino/methylsulfonyl) phenyl]methylene-indolin-2-one derivatives were synthesized. Six compounds displayed potent inhibitory activities against COX-1/2 and 5-LOX with IC(50) in the range of 0.10-9.87 mu M. Particularly, 10f exhibited well balanced inhibitory action on these enzymes (IC(50) = 0.10-0.56 mu M). More importantly, 10f and several other compounds had comparable or stronger anti-inflammatory and analgesic activities, but better gastric tolerability in vivo, as compared with darbufelone mesilate and tenidap sodium. Therefore, our findings may aid in the design of new and safe anti-inflammatory reagents for the intervention of painful inflammatory diseases, such as rheumatoid arthritis at clinic.

The first catalytic enantioselective decarboxylative Mannich-typereaction of N-unprotected ketimines is reported, directly providing N-unprotected 3-tetrasubstituted 3-aminooxindoles in high yield and ee without protection/deprotection steps. The utility of this reaction is demonstrated in the short step synthesis of (+)-AG-041R.
