Endogenous fatty acid dopamide that displays 'entourage' effects on endovanilloids NADA and anandamide. Inactive at TRPV1 and CB1 receptors (at concentrations up to 5 μM) and does not inhibit AMT or FAAH (IC50 > 25 μM). However, potentiates TRPV1-mediated effects of NADA in vitro and in vivo; enhances effects on intracellular Ca2+ (EC50 lowered 3-fold) and nociception. Also inhibits arachidonate 5-lipoxygenase (IC50 = 16 nM).
