Design, Synthesis, and Biological Evaluation of 7H-Thiazolo[3,2-b]-1,2,4-triazin-7-one Derivatives as Dual Binding Site Acetylcholinesterase Inhibitors

A series of 7H-thiazolo[3,2-b]-1,2,4-triazin-7-one derivatives were designed, synthesized and evaluated as dual binding site acetylcholinesterase inhibitors. The target compounds exhibited promising inhibitory activity for AChE. The structure-activity relationships were discussed and their binding conformation and simultaneous interactions mode were further clarified by the molecular docking studies.
