and screened as novel potential anti-Alzheimer drug candidates. These compounds showed potent inhibition activity towards cholinesterases (ChEs), among of them, 9i was the most potent one towards acetylcholinesterase (eeAChE, IC50 = 3.9 nM; hAChE, IC50 = 65.2 nM). 9i could also effectively block β-amyloid (Aβ) self-aggregation with an inhibition ratio of 47% at 20 μM. In addition, its strong anti-oxidation
合成了一系列新颖的他克林-酚酸二杂合物和他克林-酚酸-木二嗪三杂合物,表征并筛选为新型潜在的抗阿尔茨海默氏症候选药物。这些化合物显示出对胆碱酯酶(ChEs)的有效抑制活性,其中9i是对乙酰胆碱酯酶最有效的抑制因子(ee AChE,IC 50 = 3.9 nM;h AChE,IC 50 = 65.2 nM)。9i还可以有效地阻止β-淀粉样蛋白(Aβ)的自聚集,在20μM时的抑制率为47%。此外,其强大的抗氧化活性可以保护PC12细胞免受CoCl 2的影响-在实验条件下受损,而没有神经毒性。此外,其肝毒性在体外和体内均低于他克林。动力学和分子建模研究表明,9i以混合类型工作,可以同时与AChE的催化活性位点(CAS)和外围阴离子位点(PAS)相互作用。因此,9i是用于治疗AD的有希望的多功能候选药物。
