Aldose reductase, play an important role in the pathogenesis of diabetic complications such as neuropathy, nephropathy and retinopathy. Therefore design of aldose reductase inhibitors has received considerable attention. In the present study molecular insights were explored through docking and QSAR. The quantification of the structural features of Phenyl(6-phenylpyrazin-2-yl)methanone analogs inferred that atomic Senderson electronegativity, van der Waals volume and charge distribution on the molecule are decisive for the aldose reductase inhibitory activity. Moreover, docking study depicted that benzonoid system of scaffold is crucial for - interaction with the side chain of key aromatic amino acids i.e. TRP111 and TRP20. These structural insights might provide significant roadmap for continuing search of potential ARIs prior to synthesis.
