Özet

Abstract: Objective: Naphthoquinones are compounds that are common in nature which have biological activity depending on the attachment of new substituted groups. Methods: In the present study, the inhibition effects of newly synthesized naphthoquinones derivatives (I), (IIa–IId) on alpha-glucosidase, alpha-amylase, xanthine oxidase, and trypsin and antioxidant properties were investigated by in vitro studies. Results and Discussion: The synthesized compounds (IIb) (784.04 ± 79.95 µM) and (IId) (477.55 ± 1.18µM) compounds on alpha-glucosidase activity were found to have a lower IC50 value when compared to the positive control—acarbose (1628.48 ± 32.89 µM) as well as molecular docking results. Compound (IId) (690.45 ± 5.48 µM) had high 2,2-diphenyl-1-picrylhydrazil (DPPH) scavenging activity, with an IC50 value lower than that of the positive control butylated hydroxytoluene (BHT, 961.92 ± 6.41 µM). The results indicated that synthesized compounds had a dose-dependent inhibition effect on the enzymes. Conclusions: In the in vitro studies, compounds (IIb) and (IId) were strong alpha-glucosidase inhibitors as well as compound (IId) had high DPPH scavenging activity.
