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.
