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:
我们在这封信中描述了吡咯啉-2-酮作为有效的纤溶酶原激活物抑制剂1(PAI-1)抑制剂的一种新的合成方法。评价了由一锅法在NaOH水溶液中由N -2-氧乙基酰胺和醛合成的吡咯啉-2-一衍生物的PAI-1抑制活性。在这些衍生物中,发现化合物16和18具有有效的PAI-1抑制活性(化合物16:IC 50:0.69μM,化合物18:IC 50:0.65μM)。
