Abstract

Aims: The current study aimed to develop new thiourea derivatives as potential α-glucosidase inhibitors for the management of hyperglycemia in patients of Type 2 diabetes, with a focus on identifying safer and more effective antidiabetic agents. Materials & methods: New thiourea derivatives (1-16) were synthesized through single-step chemical transformation and evaluated for in vitro α-glucosidase inhibition. Kinetic studies identified the mode of inhibition, free energy and type of interactions were analyzed through density functional theory and molecular docking. Results & conclusion: Compound 5 was identified as the most potent, noncompetitive and noncytotoxic inhibitor of α-glucosidase Enzyme with a half-maximal inhibitory concentration of 24.62 ± 0.94 μM. Computational studies reinforce experimental results, demonstrating significant Enzyme interactions via hydrophobic and π-π stacking forces.
