A novel series of 4-[N-methyl-N-[(E)-3-[4-(methylsulfonyl)phenyl]-2- propenoyl]amino]benzenesulfonamides has been prepared and evaluated as membrane-bound phospholipase A2 inhibitors. A structure-activity relationship study indicated that the optimum potency was realized with the N-(phenylalkyl)piperidine derivatives 3 and 4. These compounds inhibited the liberation of arachidonic acid from the rabbit
制备了一系列新的4- [N-甲基-N-[(E)-3- [4-(甲基磺酰基)苯基] -2-丙烯酰基]氨基]苯磺酰胺,并将其评估为膜结合磷脂酶A2抑制剂。构效关系研究表明,N-(苯基烷基)哌啶衍生物3和4实现了最佳效价。这些化合物抑制了花生四烯酸从兔心脏膜组分中的释放,IC30值分别为0.028和0.009 microM。 。几种在体外被证明是有效抑制剂的化合物(3、4和28)在结扎前通过静脉给药显着降低了冠状动脉闭塞大鼠的心肌梗塞面积。N-(1-苄基-4-哌啶基)-4- [N-甲基-N-[(E)-3- [4-(甲基磺酰基)苯基] -2-丙烯酰基]氨基]-苯磺酰胺(3,ER- 3826),
