Virodhamine
Introduction
Virodhamine (O-arachidonoyl ethanolamine) is an endocannibinoid and a nonclassic eicosanoid, derived from arachidonic acid. O-Arachidonoyl ethanolamine is arachidonic acid and ethanolamine joined by an ester linkage, the opposite of the amide linkage found in anandamide. Based on this opposite orientation, the molecule was named virodhamine from the Sanskrit word virodha, which means opposition. It is an antagonist of the CB1 receptor and an agonist of CB2. Concentrations of virodhamine in the human hippocampus are similar to anandamide, but they were 2- to 9-fold higher in peripheral tissues that express CB2. Virodhamine lowers body temperature in mice, demonstrating cannabinoid activity in vivo.[1]
