Abstract

In this study, a novel series of 2,4-dioxochroman-1,2,3-triazole hybrids 8a-l was synthesized by click reaction. These compounds were screened against α-glucosidase through in vitro and in silico evaluations. All the synthesized hybrids exhibited excellent α-glucosidase inhibition in comparison to standard drug acarbose. Representatively, 3-((((1-(3,4-dichlorobenzyl)-1H-1,2,3-triazol-4-yl)methyl)amino)methylene)chroman-2,4-dione 8h with IC50 = 20.1 ± 1.5 µM against α-glucosidase, was 37-times more potent than acarbose. Enzyme kinetic study revealed that compound 8h was a competitive inhibitor against α-glucosidase. In silico docking study on chloro derivatives 8h, 8g, and 8i were also performed in the active site of α-glucosidase. Evaluations on obtained interaction modes and binding energies of these compounds confirmed the results obtained through in vitro α-glucosidase inhibition. © 2020 Bentham Science Publishers.
