Title: Synthesis and biological evaluation of 3,6-diaryl-7H-thiazolo[3,2-b] [1,2,4]triazin-7-one derivatives as acetylcholinesterase inhibitors. Author: Jin Z, Yang L, Liu SJ, Wang J, Li S, Lin HQ, Wan DC, Hu C. Journal: Arch Pharm Res; 2010 Oct; 33(10):1641-9. PubMed ID: 21052939. Abstract: 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 structure-activity relationships are discussed.[Abstract] [Full Text] [Related] [New Search]
