A group of (E)-and (Z)-1,2,3-triaryl-2-propen-1-one derivatives possessing a methylsulfonyl COX-2 pharmacophore at the para position of the C-1 phenyl ring were synthesized and evaluated as selective COX-2 inhibitors. In vitro COX-1/COX-2 structure–activity relationships were determined by varying the substituents on the C-3 propenone moiety. Among the 1,2,3-triaryl-2-propen-1-ones, (Z)-1-(4-(meth
合成并评估了一组在C-1苯环对位具有甲基磺酰基COX-2药效团的(E)和(Z)-1,2,3-三芳基-2-丙烯-1-酮衍生物作为选择性COX-2抑制剂。体外COX-1 / COX-2构效关系是通过改变C-3丙烯酮部分上的取代基来确定的。在1,2,3-三芳基-2-丙烯-1-酮中,(Z)-1-(4-(甲基磺酰基)苯基)-2,3-二苯基丙-2-烯-1-酮(3b)显示抑制COX-2的效力和选择性最高(COX-2 IC 50 = 0.07μM;选择性指数= 201)。该ž -propenones也被发现比他们更有效和选择性Ë-COX-2抑制活性的异构体。获得的结构活性数据表明,丙烯酮的几何形状以及C-3丙烯酮上的取代基类型对于COX-2抑制活性很重要。
