Design of novel N-phenylnicotinamides as selective cyclooxygenase-1 inhibitors
摘要:
A series of N-phenylnicotinamides (1-40) were designed and evaluated in vitro for their COX inhibitory activities. Most of the synthesized compounds were proved to be potent and selective inhibitors of COX-1. Compound 28 showed the most potent COX-1 inhibitory activity (COX-1 IC50 = 0.68 +/- 0.07 mu M) and good selectivity (COX-2 IC50 > 100 mu M). This compound may be useful as a lead compound for superior COX-1 inhibitors. On the basis of the biological results, structure-activity relationships for the COX-1-inhibitory activities of the synthesized N-phenylnicotinamides were discussed concisely. (C) 2010 Elsevier Ltd.
