derivatives were designed, synthesized and evaluated as potential multifunctional AChE inhibitors against Alzheimer’s disease. Most of them exhibited potent AChE inhibitory activity, high selectivity for AChE over BuChE, and moderate to good inhibitory potency toward Aβ aggregation. Specifically, compound 12c was the strongest AChE inhibitor, being 20-fold more potent than galanthamine and twofold
设计,合成和评估了一系列新的类黄酮衍生物,它们可作为对抗阿尔茨海默氏病的潜在多功能AChE抑制剂。他们中的大多数在丁酰胆碱酯酶表现出强大的乙酰胆碱酯酶抑制活性,高选择性乙酰胆碱酯酶,并适度向好的抑制能力β聚集。具体而言,化合物12C是最强的乙酰胆碱酯酶抑制剂,为20倍雪花胺更有效和双重比他克林更有效的,并且它也有能力抑制β聚集(接近参考化合物)并起金属螯合剂的作用。分子建模和酶动力学研究表明,它同时针对AChE的催化活性位点和外围阴离子位点。因此,应该对这类化合物进行彻底和系统的研究以治疗阿尔茨海默氏病。
