Based on the previous work in our group and the principle of computer-aided drug design, a series of novel beta-amino pyrrole-2-carbonitrile derivatives was designed and synthesized. Compounds 81 and 91 were efficacious and selective DPP4 inhibitors resulting in decreased blood glucose in vivo. Compound 81 had moderate DPP4 inhibitory activity (IC50 = 0.05 mu M) and good oral bioavailability (F = 53.2%). Compound 91 showed excellent DPP4 inhibitory activity (IC50 = 0.01 mu M), good selectivity (selective ratio: DPP8/DPP4 = 898.00; DPP9/DPP4 = 566.00) against related peptidases, and good efficacy in an oral glucose tolerance tests in ICR mice and moderate PR profiles (F = 22.8%, t(1/2) = 2.74 h). Moreover, compound 91 did not block hERG channel and exhibited no inhibition of liver metabolic enzymes such as CYP2C9. (C) 2014 Elsevier Masson SAS. All rights reserved.
