multiple inhibitors of cholinesterases (acetyl- and butyryl-, AChE and BChE) and monoamine oxidase B (MAO B) as potential anti-Alzheimer molecules. Starting from a previously reported potent MAO B inhibitor (3), we studied single-point modifications at the benzyloxy or at the basic moiety. The in vitro screening highlighted triple-acting compounds (6, 8, 9, 16, 20) showing nanomolar and selective MAO B inhibition
研究了一系列 4-氨甲基-7-苄氧基-2H-色烯-2-酮,旨在鉴定多种胆碱酯酶(乙酰基和丁酰基、AChE 和 BChE)和单胺氧化酶 B (MAO B) 的潜在抑制剂抗阿尔茨海默病分子。从先前报道的有效 MAO B 抑制剂 (3) 开始,我们研究了苄氧基或碱性部分的单点修饰。体外筛选突出显示了三效化合物 (6、8、9、16、20),显示出纳摩尔级选择性 MAO B 抑制作用以及低微摩尔水平下针对 ChE 的 IC50 值。对 AChE 进行酶动力学分析并对目标酶进行对接模拟,以深入了解作用机制和合理的结合模式。
