Discovery of a Novel Series of Orally Bioavailable and CNS Penetrant Glucagon-like Peptide-1 Receptor (GLP-1R) Noncompetitive Antagonists Based on a 1,3-Disubstituted-7-aryl-5,5-bis(trifluoromethyl)-5,8-dihydropyrimido4,5-dpyrimidine-2,4(1H,3H)-dione Core

摘要

A duplexed, functional multiaddition high throughput screen and subsequent optimization effort identified the first orally bioavailable and CNS penetrant glucagon like peptide-1 receptor (GLP-1R) noncompetitive antagonist. Antagonist 5d not only blocked exendin-4-stimulated insulin release in islets but also lowered insulin levels while increasing blood glucose in vivo.
