Abstract

A novel series of acridone linked to 1,2,3-triazole derivatives have been synthesized and evaluated in vitro for their acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) inhibitory activities. The synthetic approach was started from the reaction of 2-bromobenzoic acid with aniline derivatives and subsequent cyclization reaction to give acridone derivatives. Then, reaction of the later compounds with propargyl bromide followed by azide-alkyne cycloaddition reaction (click reaction) led to the formation of the title compounds in good yields. Among the synthesized compounds, 10-((1-(4-chlorobenzyl)-1H-1,2,3-triazol-4-yl)methyl)-2-methoxyacridin-9(10H)-one 9g, depicted the most potent anti-AChE activity (IC50 Combining double low line 7.31 μ1/4M). Also, docking study confirmed the results obtained through in vitro experiments and predicted possible binding conformation. © 2015 Elsevier Masson SAS.
