glycerophospho n arachidonoyl ethanolamine

N-Acylated ethanolamines (NAE) are naturally-occurring lipids that have diverse bioactivities. The different types of NAE can be derived from glycerophospho-linked precursors by the activity of glycerophosphodiesterase 1 (GDE1). Glycerophospho-N-arachidonoyl ethanolamine is the precursor of arachidonoyl ethanolamide (AEA), also known as anandamide. AEA is an endogenous cannabinoid neurotransmitter that binds to both central cannabinoid (CB1) and peripheral cannabinoid (CB2) receptors. It inhibits the specific binding of [3H]-HU-243 to synaptosomal membranes with a Ki value of 52 nM, compared to 46 nM for δ9-THC.

N-Acylated ethanolamines (NAE) are naturally-occurring lipids that have diverse bioactivities. For example, arachidonoyl ethanolamide (AEA) is an endogenous neurotransmitter that evokes cellular responses by activating the cannabinoid receptors, central cannabinoid (CB1) and peripheral cannabinoid (CB2). The different types of NAE are derived from glycerophospho-linked precursors by the activity of glycerophosphodiesterase 1 (GDE1). Glycerophospho-N-palmitoyl ethanolamine (GP-NPEA) is the metabolic precursor of palmitoyl ethanolamide (PEA). PEA is an endogenous cannabinoid found in brain, liver, and other mammalian tissues, that has potent anti-inflammatory activity in vivo. PEA has low affinity for peripheral cannabinoid (CB2) and no appreciable affinity for central cannabinoid (CB1), suggesting that its efficacy is through a different receptor.
