ranging from 0.42 nM to 79.66 nM. Amongst them, 7k, 7m and 7p, all with a 6 carbon linker between tacrine and isatin Schiff base exhibited the strongest inhibitory activity against AChE with IC50 values of 0.42 nM, 0.62 nM and 0.95 nM, respectively. They were 92-, 62- and 41-fold more active than tacrine (IC50 = 38.72 nM) toward AChE. Most of the compounds also showed a potent BuChE inhibition among
设计,合成和评估了一系列新颖的他克林-依斯汀-希夫汀席夫碱杂合衍生物(7a-p),作为对抗阿尔茨海默氏病(AD)的多目标候选药物。生物学测定表明,这些化合物大多数对乙酰胆碱酯酶(AChE)和丁酰胆碱酯酶(BuChE)表现出有效的抑制活性,并且对AChE的选择性高于BuChE。还发现它们充当出色的金属螯合剂。发现化合物7k和7m是AChE诱导的淀粉样β(Aβ)聚集的良好抑制剂。大多数化合物以0.42 nM至79.66 nM的IC50值抑制AChE。其中7k,7m和7p都在他克林和isatin Schiff碱之间具有6个碳连接基,对AChE表现出最强的抑制活性,IC50值分别为0.42 nM,0.62 nM和0.95 nM,分别。它们对他汀AChE的活性比他克林(IC50 = 38.72 nM)高92倍,62倍和41倍。大多数化合物还显示出有效的BuChE抑制作用,其中7d的BuChE的IC50值为0
