A new series of cyano-pyrazoline derivatives with a secondary amine at P-2 site was synthesized through achiral and chiral synthetic methods and evaluated for their ability to inhibit dipeptidyl peptidase IV (DP-IV). Compound 5i revealed good in vivo efficacy (ED50: 4.1 mg/kg; in vivo DP-IV inhibition). Also chiral derivative (11b) having (S)-configuration of compound 5i was found to be more potent.

A synthetic route has been developed for incorporating pyrazoline derivatives as proline surrogates in constrained X-Pro peptidomimetics. The route allows for the synthesis of dipeptide building blocks having either a six or seven-membered-ring annulated onto the pyrazoline moiety, as well as for the asymmetric synthesis of analogs having substituents on N-terminal side of the building block.
