to design new molecules and evaluate their anticholinesterase and amyloid beta (Aβ1-42) inhibition activities as multifunctional drug candidates for the treatment of Alzheimer's disease (AD). A series of 5,6-dimethoxy-1H-indene-2-carboxamides (1-22) was synthesized; cholinesterase inhibitory activities of the compounds were measured according to Ellman's colorimetric assay, while the thioflavin T assay
这项研究的目的是设计新分子并评估其抗胆碱酯酶和淀粉样蛋白β(Aβ1-42)的抑制活性,作为治疗阿尔茨海默氏病(AD)的多功能候选药物。合成了一系列的5,6-二甲氧基-1H-茚-2-羧酰胺(1-22); 根据Ellman的比色测定法测量化合物的胆碱酯酶抑制活性,而硫黄素T测定法用于测量对Aβ1-42聚集的抑制。结果表明,大多数化合物对BuChE的抑制活性均高于AChE。发现化合物20和21是最有效的BuChE抑制剂,IC50值分别为1.08和1.09μM。化合物16、20、21和22显示出对Aβ1-42聚集的显着抑制。动力学分析表明,最有效的BuChE抑制剂(20)充当非竞争性抑制剂。对接研究表明,抑制剂20与BuChE的PAS表现出许多潜在的氢键结合。这些结果表明,化合物20可能是用于预防和治疗AD的特别有前途的多功能药物。
