Chemical Structure

Biological activities

Oleamide is a CB1 cannabinoid receptor agonist. The Ki of oleamide is 1.14 and 2.63 µM for competitively inhibiting binding of the nonselective cannabinoid agonist [3H]CP55,940 and the selective CB1 antagonist [3H]SR141716A to rat whole-brain membranes, respectively. Oleamide stimulates [35S]GTPS binding in a concentration-dependent manner. The EC50 of oleamide is 1.64 µM. [1] Oleamide also activates the TRPV1 vanilloid receptor. Oleamide interacts not only with voltage-gated Na+ channels and but also allosterically with GABAA and 5-HT7 receptors as well as having cannabinoid-like actions.[2] Thus, oleamide modulates human GABAA currents (α2L) in oocytes with an EC50 of 28.94 µM.[3] Oleamide induces vasorelaxation, with an EC50 of 1.2 µM, which is reduced by endothelial removal.[4]

Protocols

In vitro: Oleamide is dissolved in 100% ethanol.[3]
