Abstract:

This paper describes the design and synthesis of a series of chalcone derivatives based on naringenin as the lead compound. The compounds were evaluated for their activities against AChE and BuChE using principles of new drug design. The intermediate benzopyran-3-formaldehyde was synthesized from commercial ortho-hydroxybenzaldehyde and acrolein using K2CO3 as a catalyst. The target compounds were obtained through the Claisen-Schmidt reaction of benzopyran-3-formaldehyde and substituted acetophenone. The inhibitory effects of the chalcone compounds against AChE and BuChE were determined using Ellman’s method. Eight compounds showed certain inhibitory activities against AChE and BuChE, with compound 2d exhibiting higher activity against cholinesterase. Molecular docking studies revealed that 2d had a significant interaction with AChE and BuChE. This study suggested that chalcone compounds, including coumarin, might provide a potential pathway for discovering new anti-AD precursors.
