Abstract

The design of an acetylcholinesterase inhibitor with multifunctional properties became the perspective for the development of an effective drug against Alzheimer's disease. Towards this target, 1-{4-hydroxy-3-[(piperidin-1-yl)methyl]phenyl}ethan-1-one (chalcone 3) was prepared and studied as an acetylcholinesterase inhibitor. The novel chalcone 3 was synthesised via Claisen-Schmidt condensation reaction with 84% yield and characterized using 1D and 2D NMR spectroscopy. The in vitro bioactivity studies of chalcone 3 demonstrated excellent inhibitory activity against AChE (IC50 1.0 nM) showing 33-fold better inhibition than donepezil, biometal chelating ability and moderate antioxidant activity. Chalcone 3 with these fascinating multifunctional proprieties can be a good candidate for the development of AD treatments. A molecular modelling investigation revealed that chalcone 3 showed dual binding inhibition of AChE enzyme. XRD shows short intra- and inter-molecular interactions with two chalcone 3 molecules per cell. Interesting Hirshfeld Surface Analysis (HSA) was conducted showing explicit agreement with the XRD analysis.
