A series of 4-hydroxyl aurone derivatives were designed synthesized and evaluated as potential multifunctional agents for the treatment of Alzheimer's disease. The results demonstrated that most of the derivatives exhibited good multifunctional properties. Among them, compound 14e displayed good inhibitory activities of self- and Cu(2+)-induced Aβ1-42 aggregation with 99.2% and 84.0% at 25μM, respectively
设计合成了一系列的4-羟基金酮衍生物,并将其评估为治疗阿尔茨海默氏病的潜在多功能剂。结果表明,大多数衍生物表现出良好的多功能性能。其中,化合物14e在25μM时表现出良好的自我抑制和Cu(2+)诱导的Aβ1-42聚集的抑制活性,分别为99.2%和84.0%,并且具有高抗氧化活性,其值为Trolox的1.90倍。此外,14e还显示出对单胺氧化酶A和B的显着抑制活性,IC50值分别为0.271μM和0.393μM。然而,6-甲氧基金氧烷15a-c显示出对MAO-B的极好的选择性。此外,代表性化合物14e和15b在体外显示出良好的金属螯合能力和血脑屏障(BBB)渗透性。
