Initialin silicoscreening process was used to find potential ligands that were later evaluated for α-amylase and α-glucosidase inhibitory potential.ResultsThe docking results revealed that the synthesized compounds were well accommodated in the binding pockets of α-glucosidase. Especially,5eand5jshowed similar interaction pattern, as previously reported Casuarine-enzyme complex.In vitroanalysis suggests that compounds5a-5kshowed varying degrees of α-amylase and α-glucosidase inhibitory activity. Amongst them,5eand5jdemonstrated good enzyme inhibition while remaining compounds showed low to moderate inhibitory potential.ConclusionsAddition of 2,5 dimethoxy substituent (2,5-dimethoxybenzaldehyde) (5e)or hydroxy, methoxy substituents (6-methoxy-2-naphthol aldehyde) (5j)at ortho and meta position exhibited good α-amylase and α-glucosidase inhibition. Hence this study provides several insights on improving the pharmacological profile of triazole containing compounds that can be adopted to design and develop novel glucosidase inhibitors.
