摘要: 本文构建乙酰胆碱酯酶抑制剂微量筛选模型,分别对检测波长、保温时间、底物浓度、酶浓度等因素条件进行优化,结果表明,乙酰胆碱酯酶抑制剂微量筛选模型最优参数为:测定波长为410 nm,反应时间20 min,ATCh浓度4 mmol/L,AChE浓度为0.5 U/mL。此外,应用50%甲醇为样品溶剂。分别利用毒扁豆碱、石杉碱甲为阳性对照,对乙酰胆碱酯酶抑制剂筛选模型进行验证。结果显示,该微量筛选模型具有良好的稳定性、特异性和灵敏性,可用于乙酰胆碱酯酶抑制剂的规模化筛选。

Abstract: To optimize the micro screening assay for acetylcholinesterase inhibitors(AChEIs),wavelength,incubation time,substrate concentration,enzyme concentration and the solvent used in the screening were evaluated.Physostigmine and huperzine A were tested as positive drugs to verify the reliability of the model.Results showed that the micro screening model for AChEIs was optimized with wavelength 410 nm,incubation time 20 min,substrate concentration 4 mmol/L,AChE concentration 0.5U/mL.In addition,50% aqueous methanol was selected as an unified solvent to dissolve the samples in the screening.Physostigmine and huperzine A test indicated that the optimized micro screening system is stable,reliable and sensitive that can be successfully used to largescale screening of AChEIs.

Key words: acetylcholinesterase, inhibitor, microscreening model
