Biological Activity
glycerophospho-n-oleoyl ethanolamine is the precursor of oleoyl ethanolamide (oea). the fatty-acid ethanolamide, oleoylethanolamide (oea) is a naturally occurring lipid. oleoylethanolamide is an endogenous ppar-α agonist. oleoylethanolamide has been involved in modulating feeding and energy homeostasis by binding to peroxisome proliferator-activated receptor-alpha (ppar-α) [1]. ppar-α is a transcription factor and a major regulator of lipid metabolism in the liver. activation of ppar-α is mainly involved in fatty acid oxidation and expressed in liver, kidney, and skeletal muscle. through ligand binding, ppar-α promotes uptake, utilization, and catabolism of fatty acids [2].oea reduced food intake and lowered body-weight gain. subchronic oea treatment (5 mg/kg, i.p., once daily for two weeks) in zucker rats initiated transcription of ppar-α and other ppar-α target gene [1]. oea is an endogenous, potent agonist for pparα. oea activated pparα with an ec50 value of 120 nm in a transactivation assay [3]. in rodents, intraperitoneal administration of oea induced satiety and peripheral utilization of lipid substrate. acute oral administration induced satiety [4].
