  Synthesis and biological evaluation of methanesulfonamide analogues of rofecoxib: Replacement of methanesulfonyl by methanesulfonamido decreases cyclooxygenase-2 selectivity

  摘要：

  A new group of 3-(4-substituted-phenyl)-4-(4-methylsulfonamidophenyl)-2(5H)furanones in which the methylsulfonyl (MeSO2) COX-2 pharmacophore present in rofecoxib was replaced by a methanesulfonamido (MeSO2NH) moiety, and where the substituent at the para-position of the C-3 phenyl ring was simultaneously varied (H, F, Cl, Br, Me, OMe), were evaluated to determine the combined effects of steric and electronic substituent properties upon COX-1 and COX-2 inhibitory potency and COX isozyme selectivity. Structure-activity relationship (SAR) studies showed that compounds having a neutral (H), or electronegative halogen (F, Cl, Br), substituent at the para-position of the C-3 phenyl ring inhibited both COX-1 and COX-2 with COX-2 selectivity indexes in the 3.1-39.4 range. In contrast, compounds having an electron-donating Me or OMe substituent were selective inhibitors of COX-2 (COX-1 IC50 > 100 mu M). These SAR,data indicate the 3-aryl-4-(4-methylsulfonamidophenyl)-2(5H)furanone scaffold provides a suitable template to design COX inhibitors with variable COX-2 selectivity indexes.
