synthesized, and tested for their ability to inhibit AChE, butyrylcholinesterase (BChE), AChE‐induced and self‐induced β‐amyloid (Aβ) aggregation and β‐secretase (BACE‐1), and to cross the blood–brain barrier. The new heterodimers consist of a unit of racemic or enantiopure huprine Y or X and a donepezil‐related 5,6‐dimethoxy‐2‐[(4‐piperidinyl)methyl]indane moiety as the active site and peripheral site to
已设计,合成和测试了新的双结合位点乙酰胆碱酯酶(AChE)抑制剂家族抑制AChE,丁酰胆碱酯酶(BChE),AChE诱导和自诱导的β-淀粉样蛋白(Aβ)聚集和β-分泌酶的能力(BACE-1),并穿越血脑屏障。新的异二聚体由外消旋或对映体纯的鸟嘌呤Y或X以及与多奈哌齐相关的5,6-二甲氧基-2-[(4-哌啶基)甲基]茚满部分组成,作为活性位点和中峡谷的外围位点相互作用的部分分别通过短的低聚亚甲基接头连接。分子动力学模拟和动力学研究支持与AChE的双位点结合。新的异二聚体是人类AChE的有效抑制剂,是人类BChE,AChE诱导和自诱导的Aβ聚集以及BACE-1的中度有效抑制剂,
