Abstract

Diabetes mellitus is a major worldwide health concern that has several serious complications including retinopathy, neuropathy, nephropathy and macrovascular diseases. Dipeptidyl peptidase-IV (DPP-IV) inhibitors, gliptins, are a new class of antidiabetic agents that potentiates the action of incretins in decreasing the blood glucose levels. In the present study, synthesis and characterization of a series of 10 N4-sulfonamido-acrylic and phthalamic acid methyl esters (3a-e and 5a-e) were achieved. In vitro anti-DPP-IV activity of the synthesized compounds was evaluated, where compound 3b demonstrated the best activity with a percent (%) inhibition of 41.7 at 10 μM concentrations and an IC50 of 23.9 μM. Moreover, Glide docking experiments revealed that our targeted compounds accommodate the binding site of DPP-IV and tend to form H-bonding with the backbones of R125, E206, S209, D545, K554, W629, Y631 and G632. Modeling findings recommend the attachment of bulky hydrophobic group on the ester side of the structure in addition to harboring extra aromatic rings that might be beneficial for better binding interaction and biological activity.
