Benzothiazole-triazole derivatives 6a–6s have been synthesized and characterized by 1HNMR and 13C-NMR. All synthetic compounds were screened for their in vitro α-glucosidase inhibitory activity by using Baker’s yeast α-glucosidase enzyme. The majority of compounds exhibited a varying degree of α-glucosidase inhibitory activity with IC50 values between 20.7 and 61.1 μM when compared with standard acarbose (IC50 = 817.38 μM). Among the series, compound 6s (IC50 = 20.7 μM) bearing a chlorine group at the 5-position of the benzothiazole ring and a tertbutyl group at the para position of the phenyl ring, was found to be the most active compound. Preliminary structure-activity relationships were established. Molecular docking studies were performed to predict the binding interaction of the compounds in the binding pocket of the enzyme.
