    Compounds with homopiperazine skeleton are designed to find a potent DPP-IV inhibitor without inhibiting CYP. Thus a series of beta-aminoacyl-containing homopiperazine derivatives was synthesized and evaluated. Compounds with acid moiety were found to be potent inhibitors of DPP-IV without inhibiting CYP 3A4. More specifically, compound 7m showed nanomolar activity with no inhibition towards five subtypes of CYPs, was considered as a prototype for further derivatization. Based on its X-ray co-crystal structure with human DPP-IV, we identified compounds 7s and 7t which showed good in vitro activity, no CYP inhibition, and good selectivity.
