inhibit AChE, butyrylcholinesterase (BChE), AChE-induced and self-induced β-amyloid (Aβ) aggregation. The new hybrids consist of a unit of 1-azabenzanthrone and a tacrine or its congener, connected through an oligomethylene linker containing an amine group at variable position. These hybrids exhibit high AChE inhibitory activity with IC50 values in the nanomolar range in most cases. Moreover, five out
一系列的双结合位点乙酰胆碱酯酶抑制剂已被设计,合成和其抑制乙酰胆碱酯酶,丁酰胆碱酯酶(BChE的)的能力进行测试,乙酰胆碱酯酶诱导的和自感应β淀粉样蛋白(β)集合。新的杂种由1-氮杂苯并蒽酮和他克林或其同类物组成,它们通过在可变位置上含有胺基的低聚亚甲基接头连接。在大多数情况下,这些杂种表现出高的AChE抑制活性,IC 50值在纳摩尔范围内。此外,五出这一系列的12个杂交体,特别是那些带有四氢部分,显示出在朝向乙酰胆碱酯酶诱导的和自感应的体外抑制活性的显著β 聚集,使其成为有希望的抗阿尔茨海默氏症候选药物。
