evaluated as novel dual inhibitors of Alzheimer's disease (AD). Most of the compounds exhibited a potent ability to inhibit amyloid-β (Aβ) aggregation and monoamine oxidases. In particular, compound 4x exhibited remarkable inhibitory activities against monoamine oxidases (IC50, 0.027 ± 0.004 μM for MAO-B; 3.275 ± 0.040 μM for MAO-A) and Aβ1-42 aggregation (54.0 ± 1.1%, 25 μM). Moreover, compound 4x showed
已经设计,合成和评估了一系列香豆素-精氨酸-杂种化合物杂种(4a-x),作为阿尔茨海默氏病(AD)的新型双重抑制剂。大多数化合物显示有效的能力,以抑制淀粉样蛋白β(A β)聚集和单胺氧化酶。特别是,化合物4倍表现出对单胺氧化酶显着的抑制活性(IC 50,0.027±0.004 μ M代表MAO-B; 3.275±0.040 μ M代表MAO-A)和A β 1-42聚集(54.0±1.1%,25 μ M)。此外,化合物4x根据体外显示低毒细胞毒性试验。血脑屏障的平行人工膜通透性测定结果表明,化合物4x可能会穿过血脑屏障。总的来说,这些发现表明化合物4x是AD疗法的有效和有希望的候选者。
