A series of 4-alkoxybenzamidines was synthesized, varying the number of carbons of the alkyl chain, and their potency as phospholipase A2 (PLA2) inhibitors was evaluated. The relationship between their capacity to inhibit PLA2 activity and their lipophilicity was examined. The optimum of the inhibitory effect against two extracellular PLA2S from rabbit platelets and bovine pancreas was observed with
合成了一系列4-烷氧基苯甲m,改变了烷基链上的碳原子数,并评估了它们作为磷脂酶A2(PLA2)抑制剂的功效。检查了它们抑制PLA2活性的能力与亲脂性之间的关系。使用带有12和14个碳原子的烷基链的化合物,观察到了对来自兔血小板和牛胰腺的两种胞外PLA2S的最佳抑制作用。这些4-十二烷基和十四烷基氧杂苯甲m抑制牛胰腺和兔血小板溶解产物PLA2S,IC50值分别为3 microM和5-5.8 microM。抑制机制是竞争性的。另外,显示4-十四烷基氧杂苯甲m在体内对角叉菜胶诱导的大鼠爪水肿起抗炎作用。
