【摘要】 目的:寻找具有钙离子拮抗作用和乙酰胆碱酯酶抑制活性双重作用机制的早老性痴呆(Alzheimer′sDisease,AD)新型抑制剂。方法:间二苯酚为底物,AD-mix-β作不对称双羟基化试剂进行凯林内酯类香豆素的全合成;所有产物进行乙酰胆碱酯酶(AchE)抑制活性测试。结论:立体选择性地合成cis3′-R,4′R-二取代角型二氢吡喃香豆素,但AchE抑制活性明显低于cis3′-R,4′R-二取代线型二氢吡喃香豆素。更多还原

【Abstract】 AIM:To obtain new typical compounds with dual mechanism,antagonizing Ca²⁺and inhibiting acetylcholinesterase,on Alzheimer’s disease.METHODS:Resorcinol was chosen as primitive substrate,and AD-mix-β as asymmetrically dihydroxylated reagent;all products were screened against acetylcholinesterase in vitro.RESULTS:cis-3′R,4′R-disubstituted angular dihydropyranocoumarins were synthesized enantioselectively,however,its inhibitory activity on acetylcholinesterase is distinctively lower than that of cis-3′R,4′R-disubstituted linear dihydropyranocoumarins.更多还原
