Abstract: With the target to develop small molecules based anti-diabetic agents, we, herein, report the design, synthesis and biological studies on Lys-Pro and Gly-Pro esters, and a Phe-Pro-Phe tripeptide inhibiting the activity of glycoprotein dipeptidyl peptidase-4 (DPP-4). Since DPP-4 cleaves the glucagon like peptide (GLP-1) and glucose dependent insulinotropic polypeptide (GIP) hormones which are responsible for inducing insulin secretion, the results of present studies could be significant in making control over glycemia. The structural analysis of DPP-4 and its binding mode with the substrate as well as the reported inhibitors provided the background for the design of new molecules. Among the 17 compounds screened against DPP-4, 14 compounds displayed IC₅₀ better than the known drug Sitagliptin. Collectively, a highly encouraging set of molecules was identified that may prove as the clinical candidates for the treatment of diabetes.
