Abstract

GPR142 is a G-protein-coupled receptor (GPCR), whose most potent and efficacious ligand has been reported as being the natural amino acid l-tryptophan. GPR142 is highly expressed in pancreatic β-cells and immune cells, suggesting the receptor may play a role in the pathogenesis and development of diabetes or inflammatory diseases. In a previous report, we developed GPR142 agonists as Insulin secretagogues. In this report, we show the discovery of a selective, potent small-molecule GPR142 antagonist, CLP-3094, and its pharmacological characteristics. These data support targeting this receptor for the treatment of chronic inflammatory diseases.
