•Synthesis of triazinoindole derivatives.•In vitro α-glucosidase inhibitory activity.•Identification of a novel class of α-glucosidase inhibitors.•Structure–activity relationship established.•Molecular docking.
A new series of triazinoindole analogs 1–11 were synthesized, characterized by EI-MS and 1H NMR, evaluated for α-glucosidase inhibitory potential. All eleven (11) analogs showed different range of α-glucosidase inhibitory potential with IC50 value ranging between 2.46±0.008 and 312.79±0.06μM when compared with the standard acarbose (IC50, 38.25±0.12μM). Among the series, compounds 1, 3, 4, 5, 7, 8, and 11 showed excellent inhibitory potential with IC50 values 2.46±0.008, 37.78±0.05, 28.91±0.0, 38.12±0.04, 37.43±0.03, 36.89±0.06 and 37.11±0.05μM respectively. All other compounds also showed good enzyme inhibition. The binding modes of these analogs were confirmed through molecular docking.
