all the synthesized derivatives can cross the blood–brain barrier (BBB) successfully. Docking analyses were performed by employing an induced-fit docking approach in the GLIDE module of Schrodinger, and the results were in agreement with their in vitro inhibitory activities. The present study resulted in the discovery of potent dual inhibitors toward MAO-B and BACE1, and these lead compounds can be fruitfully
设计、合成了一系列带有硝基的烯酰胺 ( NEA1 – NEA5 ),并评估了它们对单胺氧化酶 (MAO) 和 β 位点淀粉样前体蛋白裂解酶 1(β-分泌酶,BACE1)的抑制作用。化合物NEA3和NEA1表现出比标准品(拉扎贝胺和帕吉林的IC 50值分别 = 0.11 和 0.14 µM )更有效的 MAO-B 抑制(IC 50值分别 = 0.0092 和 0.016 µM )。此外,NEA3和NEA1对 MAO-B 的选择性指数 (SI) 值高于 MAO-A(SI 分别 >1652.2 和 >2500.0)。抑制作用和动力学研究表明NEA3和NEA1是可逆和竞争性抑制剂,对于 MAO-B ,K i值分别为 0.013 ± 0.005 和 0.0049 ± 0.0002 µM。此外,NEA3和NEA1均显示出有效的 BACE1 抑制作用,IC 508.02 ± 0.13 和 8.21 ± 0
