Abstract A series of C4-substituted tertiary nitrogen-bearing 2′-hydroxychalcones were designed and synthesised based on a previous mixed type acetylcholinesterase inhibitor. Majority of the 2′-hydroxychalcone analogues displayed a better inhibition against acetylcholinesterase (AChE) than butyrylcholinesterase (BuChE). Among them, compound 4c was identified as the most potent AChE inhibitor (IC50:
摘要 基于先前的混合型乙酰胆碱酯酶抑制剂,设计合成了一系列C4取代的叔含氮2'-羟基查耳酮。与丁酰胆碱酯酶 (BuChE) 相比,大多数 2'-羟基查耳酮类似物对乙酰胆碱酯酶 (AChE) 的抑制效果更好。其中,化合物4c被确定为最有效的 AChE 抑制剂 (IC 50 : 3.3 µM),并且对 AChE 的选择性高于 BuChE (比率 >30:1)。分子对接研究表明,化合物4c与 AChE 的外围阴离子位点 (PAS) 和催化阴离子位点 (CAS) 区域相互作用。ADMET 分析证实了化合物4c的治疗潜力基于其穿透血脑屏障。总体而言,结果表明这种 2'-羟基查耳酮值得进一步研究阿尔茨海默病 (AD) 的治疗线索。
