Description
OOleamide (301-02-0) was originally identified in the cerebrospinal fluid of sleep-deprived cats acting as an inducer of physiological sleep in animals.1 Displays agonist activity at cannabinoid CB1 receptors (Ki=8.13 μM).2 Activates PPARγ.3 Produces vasodilator effects in rats.4 Displays neuroprotective effects5 and attenuates sepsis-induced intestinal injury6.
Chemical Properties
White Powder
Definition
ChEBI: A fatty amide derived from oleic acid.
General Description
Oleamide?is a lipid or a brain fatty acid, that is found in the CSF (cerebrospinal fluid). It is originally obtained from the cerebrospinal fluid of cats, that are sleep-deprived.
Biological Activity
Endogenous sleep-inducing lipid. Acts as an agonist at the CB 1 cannabinoid receptor (EC 50 = 1.64 μ M). Also appears to potentiate the actions of 5-HT on 5-HT 2A and 2C receptors, and act via an allosteric regulatory site on 5-HT 7 receptors.
Biochem/physiol Actions
Sleep-inducing brain lipid, which allosterically modulates GABAA receptors and potentiates 5-HT7 serotonin receptor responses. Selective endogenous agonist of rat and human CB1 cannabinoid receptor.
Synthesis
Oleamide can be synthesized by ammonolysis of fatty acid or esters with ammonia gas at high pressure.
