Abstract

Type-2 Diabetes Mellitus (T2DM) is one of the most common metabolic disorders in the world and over the past three decades its incidence has increased drastically. α-Glucosidase inhibitors are used to control the hyperglycemic affect of T2DM. Herein, we report the synthesis, α-glucosidase inhibition, structure activity relationship, pharmacokinetics and docking analysis of various novel chromone based thiosemicarbazones 3(a-r). The derivatives displayed potent activity against α-glucosidase with IC₅₀ in range of 0.11 ± 0.01-79.37 ± 0.71 µM. Among all the synthesized compounds, 3a (IC₅₀ = 0.17 ± 0.026 µM), 3 g (IC₅₀ = 0.11 ± 0.01 µM), 3n (IC₅₀ = 0.55 ± 0.02 µM), and 3p (IC₅₀ = 0.43 ± 0.025 µM) displayed higher inhibitory activity as compared to the standard, acarbose. Moreover, we have developed a statistically significant 2D-QSAR model (R²_tr:0.9693; F: 50.4647 and Q²_LOO:0.9190), which can be used in future to further design potent thiosemicarbazones as inhibitors of α-glucosidase.
