Abstract

Alzheimer's disease (AD) is a multifactorial syndrome with several target proteins contributing to its etiology. In this study, we conducted a structure-based design and successfully produced a series of new multi-site AChE inhibitors with a novel framework. Compound 2e, characterized by a central benzamide moiety linked to an isoquinoline at one side and acetophenone at the other, was the most potent candidate with K(i) of 6.47nM against human AChE. Particularly, it showed simultaneous inhibitory effects against BChE, Aβ aggregation, and β-secretase. We therefore conclude that compound 2e is a very promising multi-function lead for the treatment of AD.
