Oleamide is an endogenous amide of the fatty acid oleic acid. It accumulates in the cerebrospinal fluid during sleep deprivation and induces sleep in animals.[2] It is being studied as a potential medical treatment for sleep disorders.[3] Additionally, inhibitors of the enzyme fatty acid amide hydrolase, which breaks down oleamide, lead to raised levels of oleamide, inducing sleep.[4]

The mechanism of action of oleamide's sleep inducing effects is an area of current research. It is likely that oleamide interacts with multiple neurotransmitter systems.[5] While structurally related to the endogenous cannabinoid anandamide, the ability of oleamide to bind the cannabinoid receptor CB1 is controversial. [6][7][8][9] It is likely that the hypnotic effects of oleamide are caused by elevated endocannabinoid signaling rather than direct interaction of oleamide and cannabinoid receptors.

Synthetically produced oleamide has a variety of industrial uses including as a slip agent, a lubricant, and a corrosion inhibitor.[1][10]

Oleamide was discovered and characterized by Benjamin Cravatt III and Richard Lerner at The Scripps Research Institute in La Jolla, CA.
