GPR142 is highly expressed in the pancreas and immune system and shares 33% homology with GPR139.1 Endogenous agonists identified to date include aromatic amino acids such as tryptophan and phenylalanine.2?CLP-3094? (312749-73-8) was identified as a potent and selective GPR142 antagonist with an IC50=2.3 μM against 1 mM L-tryptophan. It inhibited insulin secretion from islets induced by L-tryptophan and other agonists and displayed anti-inflammatory activity in a mouse arthritis model.3
