A novel series of meta-substituted ethanediamide and 2-butenediamide derivatives were synthesized and tested for their ability to inhibit electric eel acetylcholinesterase (AChE) and equine serum butyrylcholinesterase (BuChE). The synthesized compounds were evaluated against ChE enzymes using the colorimetric method described by Ellman et al. (Biochem. Pharmacol., 7, 1961). It was revealed that some synthesized compounds exhibited high anticholinesterase activity, among which compounds 1f and 2f were the most active inhibitors against BuChE (IC50 value=1.47 µM) and AChE (IC50 value=2.09 µM), respectively. Docking simulations revealed that the inhibitors 1f and 2f are capable of simultaneously binding the peripheral anionic site as well as the catalytic anionic site of both ChE enzymes. These derivatives are considered interesting candidates for Alzheimer’s disease treatment.
一系列新型含取代基的乙二酰胺和2-丁烯二酰胺衍生物被合成并测试其抑制电鳗乙酰胆碱酯酶(AChE)和马血清丁酰胆碱酯酶(BuChE)的能力。合成的化合物采用Ellman等人描述的比色法(《生物化学与药理学》,7卷,1961年)对抗胆碱酯酶(ChE)酶进行评估。研究显示,部分合成化合物表现出高度的抗胆碱酯酶活性,其中化合物1f和2f分别是BuChE(IC50值=1.47µM)和AChE(IC50值=2.09µM)的最有效抑制剂。对接模拟揭示,抑制剂1f和2f能够同时结合两种ChE酶的外周阴离子位点和催化阴离子位点。这些衍生物被认为是阿尔茨海默病治疗的潜在有趣候选药物。
