(7a-o) were designed, synthesized and evaluated as multi-potent anti-Alzheimer drug candidates. The screening results showed that most of them exhibited a significant ability to inhibit ChEs, certain selectivity for AChE over BuChE and strong potency inhibitory of self-induced β-amyloid (Aβ) aggregation. All IC50 values of biological activity were at the nanomolar range. Especially, compound 7c displayed
设计,合成和评估了一系列苯甲酸酯(或苯乙酸酯或肉桂酸酯)-他克林杂种(7 a - o)作为多效抗阿尔茨海默氏症候选药物。筛选结果表明,它们中的大多数具有抑制ChEs的能力,相对于BuChE具有一定的AChE选择性和对自诱导的β-淀粉样蛋白(Aβ)聚集的强力抑制作用。所有的IC 50生物活性值均在纳摩尔范围内。特别地,化合物7c显示出最大的抑制AChE的能力,IC 50值为5.63 nM,选择性最高,BuChE / AChE之比为64.6。此外,它还具有IC 50对Aβ聚集的有效抑制作用。值为51.81 nM。Lineweaver-Burk图和分子建模研究表明,化合物7c靶向ChEs的CAS和PAS。结构-活性关系分析表明,通过乙酰基与他克林相连的芳香环的电子密度在确定抑制活性中起着重要作用。
