We established the stereoselective synthesis of (E)-3-methoxycarbonyl-2,4,6-trienal compound A and discovered that the compound A showed more powerful inhibitory activity toward phospholipase A2(PLA2) from bovine pancreas than manoalide which is a typical PLA2 inhibitor. As the inhibitory mechanism of PLA2 by A, the irreversible formation of dihydropyridine derivative resulting from the reaction of
我们建立了(E)-3-甲氧基羰基-2,4,6-三烯醛化合物A的立体选择性合成方法,发现该化合物A对牛胰腺中磷脂酶A 2(PLA 2)的抑制作用比对作为主体的Manoalide具有更强的抑制作用。典型的PLA 2抑制剂。作为PLA的抑制机构2由甲,二氢吡啶衍生物由此而来从反应不可逆地形成甲与PLA赖氨酸残基2是基于模型的反应方案。此外,A 通过MALDI-TOF-MS肽图分析发现,Lys56被选择性地修饰了包括在该酶的界面识别位点中的Lys56。
