and alkaline phosphatase inhibition studies. Most of the tested compounds showed promising activities, amongst them (6k) and (6q) showed excellent acetylcholinesterase inhibitory activity with IC50 0.241 ± 0.012 and 0.260 ± 0.013 µM, respectively, as compared with those of standard drug whereas the compound (6p), with IC50 0.044 ± 0.001 µM, was found to be the most potent inhibitor of alkaline phosphatase
一个新的4,5-二取代-2,4-二氢-3 H -1,2,4-三唑-3-硫酮(6a – s)和2,5-二取代-1,3,4-噻二唑(通过在4 N氢氧化钠水溶液中回流和分别与多磷酸搅拌过夜,将各种1,4-二取代的硫代氨基脲衍生物(5a - s)进行分子内脱氢环化反应,合成7a - h)。这些化合物的结构由IR,1 H和13表征13 C NMR,元素分析和质谱研究。筛选所有合成的化合物的乙酰胆碱酯酶和碱性磷酸酶抑制研究。大多数所测试的化合物显示有希望的活动,在他们之中(6K)和(6Q)表现出优异的乙酰胆碱酯酶抑制活性用IC 50 0.241±0.012和0.260±0.013μM,分别作为与标准药物的,而化合物(比较6P) IC 50为0.044±0.001 µM,是最有效的碱性磷酸酶抑制剂。
