Title: The discovery of novel 5,6,5- and 5,5,6-tricyclic pyrrolidines as potent and selective DPP-4 inhibitors. Author: Cox JM, Chu HD, Kuethe JT, Gao YD, Scapin G, Eiermann G, He H, Li X, Lyons KA, Metzger J, Petrov A, Wu JK, Xu S, Sinha-Roy R, Weber AE, Biftu T. Journal: Bioorg Med Chem Lett; 2016 Jun 01; 26(11):2622-6. PubMed ID: 27106708. Abstract: Novel potent and selective 5,6,5- and 5,5,6-tricyclic pyrrolidine dipeptidyl peptidase IV (DPP-4) inhibitors were identified. Structure-activity relationship (SAR) efforts focused on improving the intrinsic DPP-4 inhibition potency, increasing protease selectivity, and demonstrating clean ion channel and cytochrome P450 profiles while trying to achieve a pharmacokinetic profile suitable for once weekly dosing in humans.[Abstract] [Full Text] [Related] [New Search]
