Abstract
As part of a project aimed at developing new agents for potential application in Alzheimer's disease, a new series of acetophenone derivatives which possess alkylamine side chains were designed, synthesized and assayed as acetylcholinesterase (AChE) inhibitors that could simultaneously bind to the peripheral and catalytic sites of the enzyme. The compounds were synthesized, and the inhibitory activities toward AChE and butyrylcholinesterase (BuChE) in vitro were determined using a modified Ellman method. Of the compounds tested, 6 derivatives were found to inhibit AChE in the micromolar range. The best compound, 2e, had an IC50 of 0.13 μM. A detailed molecular modeling study was performed to explore the interaction of 2e with AChE.
