甘油磷酸-N-棕榈酰乙醇胺（GP-NPEA）是棕榈酰乙醇酰胺（PEA）的代谢前体。PEA是一种在肝脏，大脑和其他哺乳动物组织中发现的内源性大麻素，具有有效的抗炎活性。PEA对CB1没有明显的亲和力，而对CB2没有低亲和力，表明其功效是通过不同的受体实现的。 Glycerophospho-N-palmitoyl ethanolamine (GP-NPEA) is the metabolic precursor of palmitoyl ethanolamide (PEA). PEA is an endogenous cannabinoid found in liver, brain, and other mammalian tissues, that has potent antiinflammatory activity. PEA has no appreciable affinity for CB1 and low affinity for CB2, suggesting that its efficacy is through a different receptor.
