series of compounds obtained by fusing the cholinesterase inhibitor donepezil and the antioxidant ebselen were designed as multi-target-directed ligands against Alzheimer’s disease. An in vitro assay showed that some of these molecules did not exhibit highly potent cholinesterase inhibitory activity but did have various other ebselen-related pharmacological effects. Among the molecules, compound 7d, one
通过将胆碱酯酶抑制剂多奈哌齐和抗氧化剂依布硒啉融合获得的一系列新化合物被设计为针对阿尔茨海默氏病的多靶标配体。体外测定表明,这些分子中的某些分子没有表现出强效的胆碱酯酶抑制活性,但确实具有与依布硒仑相关的各种其他药理作用。在这些分子中,发现化合物7d是最有效的乙酰胆碱酯酶抑制剂之一(电泳电乙酰胆碱酯酶的IC 50值为0.042μM,人乙酰胆碱酯酶的IC 50值为0.097μM),是一种强丁酰胆碱酯酶抑制剂(IC 50值为1.586μM),拥有快速的H 2 O 2和过氧亚硝酸盐清除活性,谷胱甘肽过氧化物酶样活性(ν 0 = 123.5μM分钟-1),并且是哺乳动物的TrxR的基板。小鼠毒性试验显示,剂量高达2000 mg / kg时无急性毒性。根据体外血脑屏障模型,7d能够穿透中枢神经系统。
