We describe in this Letter a new synthetic method for pyrrolin-2-ones as potent plasminogen activator inhibitor-1 (PAI-1) inhibitors. Pyrrolin-2-one derivatives synthesized from N-2-oxoethylamides and aldehydes in aqueous NaOH by one-pot were evaluated for their PAI-1 inhibitory activity. Among these derivatives, compounds 16 and 18 were found to possess potent PAI-1 inhibitory activity (compound 16: IC(50): 0.69microM, compound 18: IC(50): 0.65microM).
在这封信件中,我们描述了一种新的吡咯啉-2-酮类化合物的合成方法,该化合物是有效的纤溶酶原激活物抑制剂-1(PAI-1)抑制剂。通过一锅法,用 N-2-氧代乙基酰胺和醛在氢氧化钠水溶液中合成了吡咯啉-2-酮衍生物,并对它们的 PAI-1 抑制活性进行了评价。在这些衍生物中,化合物 16 和 18 被发现具有很强的 PAI-1 抑制活性(化合物 16:IC(50):0.69μM,化合物 18:IC(50):0.65μM)。
