Abstract

In this work, a series of derivatives containing 1,2,3-triazole and isoxazole were synthesized. All of them were evaluated as novel dual AChE inhibitors. Most of synthesized compounds showed moderate to good inhibitory potency toward AChE. Among them, N-((1-(4-methylbenzyl)-1H-1,2,3-triazol-4-yl)methyl)-5-(p-tolyl)isoxazole-3-carboxamide (5m) was the most potent AChE inhibitor, being 12-fold more potent than rivastigmine, as the reference drug. Also, molecular modeling revealed that compound 5m targeted both the catalytic anionic site (CAS) and the peripheral anionic site (PAS) of AChE. ©2017 Bentham Science Publishers.
