Abstract :In this study, a novel series of benzofuran derivatives (2a-2k) were synthesized and the structures of the obtained compounds were elucidated by 1H NMR, 13C NMR and HRMS spectra. The compounds were investigated for their anticholinesterase and antioxidant potentials. The ferrous ion chelating activity of the compound 2g at 50 µM concentration was 68.25%, surpassing those of rutin and BHT (13.21% and 2.57%, respectively). Besides, according to DPPH radical scavenging activity assay, compound 2g exhibited the most potent antioxidant activity with an IC50 value of 30.14 ± 0.005 µM, when compared to standard gallic acid (IC50= 29.48 ± 0.014 µM). Furthermore, compounds 2d (10.33%) and 2i (20.17%), showed the highest inhibitory activity against AChE and BChE, respectively. Compound 2i exhibits important interactions with the active site of BChE, according to the in silico molecular docking study. Also, the in silico ADMET study revealed the desirable pharmacokinetic properties of compound 2i. Therefore, compounds 2g and 2i could be deemed as promising candidates for the designing dual functional antioxidant and butyrylcholinesterase inhibitors in the management of Alzheimer’s disease.
