Abstract:

A series of (4-(2,4,5-trifluorophenyl)piperazin-1-yl) methanone derivatives 9a-k as potential dipeptidyl peptidase-4 (DPP-4) inhibitors were synthesized by microwave assisted nucleophilic substitution of 1,2,4,5-tetrafluorobenzene with piperazine, followed by carbamoylation and condensation. The inhibitory activities of these new compounds on DPP-4 were evaluated in vitro, and compounds 9d and 9g showed moderate inhibitory activities.

Key words: DPP-4, DPP-4 inhibitor, Derivative, Synthesize
