Commendamide (N-acyl-3-hydroxypalmitoyl-glycine) is a newly discovered GPCR G2A/GPR132 agonist (EC50=11.8 μM) that isolated from Bacteroides vulgatus. [1] G2A/GPR132 belongs to the guanine nucleotide-binding protein (G protein)-coupled receptor (GPCR) superfamily. GPR132/G2A is first reported to be a transcriptional target for BCR-ABL tyrosine kinase attenuating B-cell expansion in vitro and arresting cells at G2 during mitosis. It has been involved in autoimmune disease and atherosclerosis. [1] Commendamide and structurally related endogenous long-chain N-Acyl-amides activates discrete human receptors. In a screen for agonist activity against a library of 242 GPCRs, commendamide is found to activate a single receptor G2A/GPR132. This activity is confirmed by a synthetic sample of commendamide. Commendamide analogs with changes in the head group or acyl chain also exhibited reduced GPR132/G2A activity. [1]
