were designed and synthesized based on 2,3,4,9-tetrahydro-1H-carbazole attached benzyl pyridine moieties. In-vitro assay revealed that all of the designed compounds were selective and potent BuChE inhibitors. The most potent BuChE inhibitor was compound 6i (IC50 = 0.088 ± 0.0009 μM) with the mixed-type inhibition. Docking study revealed that 6i is a dual binding site BuChE inhibitor. Also, Pharmacokinetic
丁酰胆碱酯酶(BuChE)抑制剂已成为治疗阿尔茨海默氏病(AD)的有趣靶标。基于2,3,4,9-四氢-1H-咔唑连接的苄基吡啶部分,设计和合成了一系列双结合位点BuChE抑制剂。体外测定表明,所有设计的化合物均为选择性和有效的BuChE抑制剂。最有效的BuChE抑制剂是化合物6i(IC 50 = 0.088±0.0009μM),具有混合型抑制作用。对接研究表明6i是BuChE双重结合位点抑制剂。同样,6i的药代动力学特性与Lipinski的定律是准确的。此外,化合物6i表现出神经保护和β-分泌酶(BACE1)抑制活性。该化合物还可以分别在100μM和10μM的浓度下抑制AChE诱导的Aβ肽和自身诱导的Aβ肽聚集。通常,结果显示为具有治疗AD潜在治疗潜力的新型有效BuChE抑制剂。
