(3R)-4-[(3R)-3-Amino-4-(2, 4, 5-trifluorophenyl) butanoyl]-3-(2, 2, 2-trifluoroethyl)-1, 4-diazepan-2-one, a selective dipeptidyl peptidase IV inhibitor for the treatment of …
Replacement of the triazolopiperazine ring of sitagliptin (DPP-4 IC50= 18nM) with 3-(2, 2, 2- trifluoroethyl)-1, 4-diazepan-2-one gave dipeptidyl peptidase IV (DPP-4) inhibitor 1 which is potent (DPP-4 IC50= 2.6 nM), selective, and efficacious in an oral glucose tolerance test in mice. It was selected for extensive preclinical development as a potential back-up candidate to sitagliptin.
