Human dipeptidyl peptidase 4 in complex with a diazepan-2-one inhibitor
Overview
Replacement of the triazolopiperazine ring of sitagliptin (DPP-4 IC(50)=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 IC(50)=2.6nM), 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.
About this Structure
2IIT is a Single protein structure of sequence from Homo sapiens with , and as ligands. Active as Dipeptidyl-peptidase IV, with EC number 3.4.14.5 Full crystallographic information is available from OCA.
