摘要
A group of 1,3-diarylurea derivatives, possessing a methylsulfonyl pharmacophore at the para-position of the N-1 phenyl ring, in conjunction with a N-3 substituted-phenyl ring (4-F, 4-Cl, 4-Me, 4-OMe), were designed and synthesized for evaluation as selective cyclooxygenase-2 (COX-2) inhibitors. In vitro COX-1/COX-2 isozyme inhibition structure - activity studies identified 1-(4methylsulfonylphenyl)-3-(4- methoxyphenyl) urea (4e) as a potent COX-2 inhibitor (IC50 = 0.11 mu M) with a high COX-2 selectivity index ( SI = 203.6) comparable to the reference drug celecoxib (COX-2 IC50 = 0.06 mu M; COX-2 SI =405). The structure - activity data acquired indicate that the urea moiety constitutes a suitable scaffold to design new acyclic 1,3-diarylurea derivatives with selective COX-2 inhibitory activity.
