PSN632408 is an optimized agonist of GPR119 receptors that display similar potency to OEA at both recombinant mouse and human GPR119 receptors (EC50: 5.6 and 7.9 uM, respectively).

GPR119 (previously designated SNORF25) is an orphan G protein-coupled receptor expressed predominantly in the pancreas and gastrointestinal tract in humans and in the brain, pancreas, and gastrointestinal tract in rodents. GPR119 agonist Systemic administration of PSN632408 (30 mg/kgintraperitoneally) inhibits food intake, reduces weight gain, and white adipose tissue deposition in rats. It mediates a reduction in food intake and body weight gain in rats upon treatment with oleoyl ethanolamide (OEA), an endogenous, potent agonist for PPARα. These data suggest that PSN632408 may be useful as a therapeutic agent for the treatment of obesity.
