N-Arachidonoyl dopamine (NADA) is an endocannabinoid that acts as an agonist of the CB1 receptor and the transient receptor potential V1 (TRPV1) ion channel. NADA was first described as a putative endocannabinoid (agonist for the CB1 receptor) in 2000[1] and was subsequently identified as an endovanilloid (agonist for TRPV1) in 2002[2]. NADA is an endogenous arachidonic acid based lipid found in the brain of rats, with especially high concentrations in the hippocampus, cerebellum, and striatum[2]. It activates the TRPV1 channel with an EC50 of approximately of 50nM. The high potency makes it the putative endogenous TRPV1 agonist.[3]
In mice, NADA was shown to induce the tetrad of physiological paradigms associated with cannabinoids: hypothermia, hypo-locomotion, catalepsy, and analgesia[1][4][5]. NADA has been found to play a regulatory role in both the peripheral and central nervous systems, and displays antioxidant and neuroprotectant properties[6][7][8][9][10]. NADA has also been implicated in smooth muscle contraction and vasorelaxation in blood vessels[11][12][13][14]. Additionally, NADA has been observed to suppress inflammatory activation of human Jurkat T cells and to inhibit the release of prostaglandin E2 (PGE2) from LPS-activated astrocytes, microglia and mouse brain ECs (MEC-Brain)[15][16][17]. NADA also promotes the inflammatory resolution of human endothelial cells activated by both endogenous (i.e. TNF) and exogenous (i.e. bacterial derived lipopolysaccharide (TLR4 agonist) and FSL-1 (TLR2/6 agonist)) inflammatory mediators[18]. Furthermore, NADA also displays inhibitory activity in HIV-1 replication assays[19]. Finally, NADA can prevent the degranulation and release of TNF from RBL- 2H3 mast cells treated with an IgE-antigen complex[20]. Together, theses studies show that physiological functions attributed to NADA are multifaceted, and include the potential to modulate the immune response.
Several cytochrome P450 endoplasmic reticulum-bound enzymes, i.e. CYP4A11, CYP4F2, CYP4F3, CYP4Z1, and CYP2U1 in humans,[21][22][23][24][25][26] Cyp4a12a and Cyp4a12b ins mice,[27] and Cyp4a1, Cyp4a2, Cyp4a3, and Cyp4a8 in rats[21] ω-hydroxylate arachidonic acid to form 20-hydroxyeicosatetraenoic acid (20-HETE) and lesser amounts of 19-hydroxyeicosatetraenoate (19-HETE) (see 20-Hydroxyeicosatetraenoic acid). Rat liver endoplasmic reticulum (i.e. microsome) preparations hydroxylated MADA to 20-hydroxy and lesser amounts of 19-hydroxy arachidonoyl dopamine products; both metabolites as well as 18-hydroxy arachidonoyl dopamine stimulated recombinant human TRPV(1) receptors, being about 10-fold less potent than NADA in doing so.[28] These results identify a variety of metabolically modified NADA's as potential TRPV1 agonists and suggest that one or more of the cited cytochrome P450 enzymes may be involved in inactivating NADA.
