their multifunctional properties against cholinesterases (ChEs) and monoamine oxidases (MAOs). The in vitro enzymatic assay results revealed that the tested hydrazones have exhibited excellent cholinesterase inhibition profile. Compound 4i, (E)-N'-(2,3-dichlorobenzylidene)benzo[d][1,3]dioxole-5-carbohydrazide showed promising dual inhibitory profile against AChE (0.048 ± 0.007 μM), BChE (0.89 ± 0.018 μM)
摘要 合成了具有可变芳基部分的胡椒酸衍生腙文库,并研究了它们针对胆碱酯酶(ChE)和单胺氧化酶(MAO)的多功能特性。体外酶测定结果表明,测试的腙表现出优异的胆碱酯酶抑制特性。化合物4i , (E ) -N' -(2,3-二氯亚苄基)苯并[d][1,3]二氧杂环戊烯-5-碳酰肼显示出对 AChE (0.048 ± 0.007 μM)、BChE (0.89 ± 0.018) 的双重抑制特性。 μM) 和 MAO-B (0.95 ± 0.12 μM) 酶。SAR 探索表明,连接缩氨基脲支架的两个芳基结合位点的连接体被一个原子截断,相对抑制了 AChE 抑制潜力。动力学研究表明,化合物4i以竞争性方式可逆地抑制 AChE 酶 ( K i = 8.0 ± 0.076 nM),同时对 MAO-B 表现出非竞争性可逆抑制特性 ( K i = 9.6 ± 0.021 µM)。此外,针对 ChE 和 MAO
