Acetylcholinesterase (AChE) inhibitors played an important role in developing a cure for Alzheimer’ s disease. In order to study on the influence of modifications at different groups and side chains on the AChE inhibitory ability and the active sites of 7H-thiazolo[3,2-b][1,2,4]triazin-7-one derivatives, fourteen 3,6-diaryl-7H-thiazolo[3,2-b][1,2,4]triazin-7-one derivatives were designed and synthesized. The study of AChE inhibitory activity was carried out using the Ellman colorimetric assay with huperzine-A as the positive control drug. Most of the target compounds exhibited more than 50% inhibition at 10 μM. Some target compounds showed strong inhibition against AChE. The molecular fields analysis and preliminary structureactivity relationships are discussed.
乙酰胆碱酯酶(AChE)抑制剂在开发阿尔茨海默病的治疗方法中扮演了重要角色。为了研究不同基团和侧链修饰对7H-噻唑并[3,2-b][1,2,4]三嗪-7-酮衍生物的AChE抑制能力和活性部位的影响,设计并合成了十四个3,6-二芳基-7H-噻唑并[3,2-b][1,2,4]三嗪-7-酮衍生物。使用Ellman比色法以石杉碱甲作为阳性对照药物进行了AChE抑制活性的研究。大多数目标化合物在10 μM下表现出超过50%的抑制作用。某些目标化合物显示出对AChE的强烈抑制作用。讨论了分子场分析和初步的构效关系。
