ARACHIDOYL ETHANOLAMIDE

Description

The endocannabinoids present a rich system of central cannabinoid (CB₁), peripheral cannabinoid (CB₂), and non-CB receptor-mediated pharmacology that has stimulated research in many fields including memory, weight loss and appetite, neurodegeneration, tumor surveillance, analgesia, and inflammation.^1,2 Arachidoyl ethanolamide is one of the saturated fatty acyl ethanolamides devoid of classical (CB₁/CB₂) activity. Arachidoyl ethanolamide does not bind to the murine CB₁ receptor³ and does not compete with anandamide as a substrate for the endocannabinoid hydrolytic enzyme fatty acid amide hydrolase.⁴ Non-CB receptor-mediated pharmacology of the saturated ethanolamides is still being elucidated.⁵

Definition

ChEBI: N-(icosanoyl)ethanolamine is an N-(long-chain-acyl)ethanolamine that is the ethanolamide of eicosanoic acid. It is a N-(long-chain-acyl)ethanolamine and a N-(saturated fatty acyl)ethanolamine. It is functionally related to an icosanoic acid.
