A series of novel compounds 6a–h, 8i–1, 10s–v, and 16a–d were synthesized and evaluated, together with the known analogs 11a–f, for their inhibitory activities towards acetylcholinesterase (AChE) and butyrylcholinesterase (BChE). The inhibitory activities of AChE and BChE were evaluated in vitro by Ellman method. The results show that some compounds have good inhibitory activity against AChE and BChE
合成并评估了一系列新型化合物 6a-h、8i-1、10s-v 和 16a-d,以及已知的类似物 11a-f,评估它们对乙酰胆碱酯酶 (AChE) 和丁酰胆碱酯酶 (BChE) 的抑制活性。采用Ellman法评价AChE和BChE的体外抑制活性。结果表明,部分化合物对AChE和BChE具有良好的抑制活性。其中,化合物8i对AChE(eeAChE IC50 = 0.39 μM)和BChE(eqBChE IC50 = 0.28 μM)均表现出最强的抑制作用。酶抑制动力学和分子模型研究表明,化合物 8i 同时与 AChE 和 BChE 的外周阴离子位点 (PAS) 和催化位点 (CAS) 结合。此外,化合物8i的细胞毒性低于他克林,表明其作为抗阿尔茨海默病(抗AD)药物的潜在安全性。总之,这些数据表明化合物8i是一种有前途的治疗AD的多效药物。
