en original New resveratrol analogs as improved biologically active structures: design, synthesis and computational modeling
New analogs of the well-known bioactive trihydroxy-stilbene resveratrol were synthesized to investigate their potential biological activity. The focus was on assessing their ability to inhibit cholinesterase enzymes (ChEs) and their antioxidative properties, which were thoroughly examined. New resveratrol analogs were synthesized through Wittig or McMurry reaction in moderate-to-good yields. In all synthetic pathways, mixtures of cis- and trans-isomers were obtained, then separated by chromatography, and trans-isomers were isolated as targeted structures. The stilbene derivatives underwent evaluation for antioxidant activity (AOA) using DPPH and CUPRAC assay, and their potential to inhibit acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) was also measured. The biological tests have shown that the same compounds exhibited significant antioxidative and butyrylcholinesterase inhibitory potential, as evidenced by lower IC50 values compared to the established standards, trans-resveratrol, and galantamine, respectively. Additionally, molecular docking of the selected synthesized potential inhibitors to the enzyme's active site was performed, followed by assessing the complex stability using molecular dynamics simulation lasting 100 nanoseconds. Lastly, the new compounds underwent examination to determine their potential mutagenicity.
