A series of novel aurones bearing amine and carbamate functionalities at various positions (rings A and/or B) of the scaffold was synthesized and evaluated for their acetylcholinesterase and butyrylcholinesterase inhibitory activities. Structure–activity relationship study disclosed several potent submicromolar acetylcholinesterase inhibitors (AChEIs) particularly aurones bearing piperidine and pyrrolidine
Design, synthesis and anticholinesterase activity of a novel series of 1-benzyl-4-((6-alkoxy-3-oxobenzofuran-2(3H)-ylidene) methyl) pyridinium derivatives
benzofuranone-ylidene-methyl benzylpyridinium derivatives (6a–u) were synthesized as acetylcholinesterase inhibitors. The anticholinesteraseactivity of synthesized compounds was measured using colorimetric Ellman’s method. It was revealed that some synthesized compounds exhibited high anticholinesteraseactivity, among them compound 6b was the most active compound (IC50 = 10 ± 6.87 nM).
