Abstract

Background: α-Glucosidase is a hydrolyzing enzyme that plays a crucial role in the degradation of carbohydrates and starch to glucose. Hence, α-glucosidase is an important target in car-bohydrate mediated diseases such as diabetes mellitus. Objective: In this study, novel coumarin containing dithiocarbamate derivatives 4a-n were synthesized and evaluated against α-glucosidase in vitro and in silico. Methods: These compounds were obtained from the reaction between 4-(bromomethyl)-7-methoxy-2H-chromen-2-one 1, carbon disulfide 2, and primary or secondary amines 3a-n in the presence of potassium hydroxide and ethanol at room temperature. In vitro α-glucosidase inhibition and kinetic study of these compounds were performed. Furthermore, a docking study of the most potent compounds was also performed by Auto Dock Tools (version 1.5.6). Results: Obtained results showed that all the synthesized compounds exhibited prominent inhibi-tory activities (IC50 = 85.0 ± 4.0-566.6 ± 8.6 µM) in comparison to acarbose as a standard inhibitor (IC50 = 750.0 ± 9.0 µM). Among them, the secondary amine derivative 4d with pendant indole group was the most potent inhibitor. Enzyme kinetic study of the compound 4d revealed that this compound competes with a substrate to connect to the active site of α-glucosidase and therefore is a competitive inhibitor. Moreover, a molecular docking study predicted that this compound inter-acted with the α-glucosidase active site pocket. Conclusion: Our results suggest that the coumarin-dithiocarbamate scaffold can be a promising lead structure for designing potent α-glucosidase inhibitors for the treatment of type 2 diabetes. © 2021 Bentham Science Publishers.
