7% of cell viability, respectively, at 10 μM). The preliminary SARs analysis indicated that benzene ring is the key factor for the neuroprotective activity and the bromo atom substituted at 4-position of the benzene ring favors the neuroprotective activity. In addition, the fluoro group in the benzene ring appears not beneficial for the neuroprotective activity. Graphical abstract
摘要一系列新的基于苯并噻唑基-1,3,4-恶二唑衍生物的合成和评价它们的抗Aβ的神经保护作用25-35诱导的SH-SY5Y细胞毒性。生物测定结果表明,大多数测试化合物显示出有希望的神经保护活性。特别是,化合物2-[[[[[5-[(4-溴苯基甲基)硫基] -1,3,4-恶二唑-2-基]甲基]硫基]苯并噻唑显示出最强的活性(10.7%的细胞活力) μM),优于阳性对照EGCG(10μM时细胞活力的90.7%)。此外,化合物2-[[[[[5-[(2-溴苯基甲基)硫代] -1,3,4-恶二唑-2-基]甲基]硫代]苯并噻唑,2-[[[[5-[(4-溴- 2-氟苯基甲基)硫代] -1,3,4-恶二唑-2-基]甲基]硫代]苯并噻唑和2-[[[[5-[(4-甲氧基苯基甲基)硫代] -1,3,4-恶二唑- 2-基]甲基]硫代]苯并噻唑的神经保护活性与EGCG相似(在10μM时分别为87.7、89.1和87.
