heterocycles (e.g., morpholine, tetrahydroisoquinoline, benzimidazole, piperidine) and alkylene spacers (2 to 10 methylene groups between carbamate and heterocycle) in the carbamate residue was synthesized and characterized in vitro for their binding affinity, binding kinetics, and carbamate hydrolysis. These novel BChE inhibitors are highly selective for hBChE over human acetycholinesterase (hAChE), yielding
在这项研究中,假性不可逆丁酰胆碱酯酶(BChE)抑制剂的氨基甲酸酯结构针对与酶的更长结合时间进行了优化。合成了一组在氨基甲酸酯残基中带有不同杂环的化合物(例如吗啉,四氢异喹啉,苯并咪唑,哌啶)和亚烷基间隔基(氨基甲酸酯和杂环之间的2至10个亚甲基),并在体外对其结合亲和力,结合动力学,和氨基甲酸酯水解。这些新型BChE抑制剂对h BChE的选择性高于人乙酰胆碱酯酶(h AChE),可产生短,中和长效纳摩尔hBChE抑制剂(氨基甲酰化酶的半衰期为1至28小时)。抑制剂在鼠海马细胞系和阿尔茨海默氏病(AD)的药理小鼠模型中显示神经保护特性,表明BChE抑制对于AD的疾病改良治疗具有显着的益处。
