Following the discovery of N-acyl-1,4-diazepan-2-one as a novel pharmacophore for potent and selective DPP-4 inhibitors, optimization of this new lead with different substitution on the seven-membered ring resulted in several highly potent and selective, orally bioavailable, and efficacious DPP-4 inhibitors, such as 3R-methyl-1-cyclopropyl-1,4-diazepan-2-one derivative 9i (DPP-4 IC(50)=8.0 nM) and 3R,6R-dimethyl-1
