Identification of a series of 3-(benzo[d]oxazol-2-yl)-5-(1-(piperidin-4-yl)-1H-pyrazol-4-yl)pyridin-2-amines, as a new class of G-protein-coupled receptor kinase 2 and 5 inhibitor

Abstract

The arising critical implications of G-protein-coupled receptor kinase 2 and 5 (GRK2 and 5) in heart failure have been attracting attention and inhibitors of GRK2 and 5 were considered as a novel therapeutic strategy to prevent and treat heart failure disease. Despite this large therapeutic potential, to date few GRK2 inhibitors have been identified and GRK5 inhibitors in public have been unknown. In our efforts to discover a novel scaffold with potent GRK2 and GRK5 inhibitory activities, we found that a series of 3-(benzo[d]oxazol-2-yl)-5-(1-(piperidin-4-yl)-1H-pyrazol-4-yl)pyridin-2-amines have been identified as a new class of GRK2 and 5 kinase inhibitor. Structural modification of parent benzoxazole scaffolds by introducing substituents on phenyl displayed potent inhibitory activities toward GRK2 and 5. This research highlight discusses the processing and findings of the recent study.
