Background
Arachidonoyl ethanolamide-d8 (AEA-8) contains eight deuterium atoms at the 5, 6, 8, 9, 11, 12, 14, and 15 positions. It is intended for use as an internal standard for the quantification of AEA by GC- or LC-mass spectrometry. AEA is the ethanolamine amide of arachidonic acid, first isolated from porcine brain.1 It is an endogenous cannabinoid neurotransmitter that binds to both CB1 and CB2 receptors.2 AEA 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.1
