Ananamide, also known as arachidonoylethanolamide or AEA, is an endogenous cannabinoid neurotransmitter found in animal and human organs, especially in the brain. It was isolated and its structure was elucidated by Czech analytical chemist Lumír Ondřej Hanuš and American molecular pharmacologist William Anthony Devane in the Laboratory of Raphael Mechoulam, at the Hebrew University in Jerusalem, Israel in 1992. The name is taken from the Sanskrit word ananda, which means "bliss, delight", and amide. It is degraded by the fatty acid amide hydrolase (FAAH) enzyme which converts anandamide into ethanolamine and arachidonic acid. As such, inhibitors of FAAH lead to elevated anandamide levels and are being pursued for therapeutic use.
