NADA Usage And Synthesis

Description

N-Arachidonoyldopamine (199875-69-9) is an endogenous conjugate of arachidonic acid and dopamine.1?May be the “endogenous capsaicin like substance” in the CNS acting at TRPV1 channels, EC50~ 50 nM1. Also acts as a selective cannabinoid CB1 agonist (Ki=0.25 and 15 μM for CB1 and CB2 respectively)2?and results in a distinct signaling profile from any known cannabinoid3. Competitive inhibitor of FAAH and anandamide transport.4. Modulates acute systemic inflammation via non-hematopoietic TRPV1.5

Uses

NADA is a endogenous CB1 agonist, as well as a vanilloid agonist and inhibitor of FAAH and AMT.

Definition

ChEBI: Arachidonoyl dopamine is a fatty amide, a member of catechols, a secondary carboxamide and a N-(fatty acyl)-dopamine. It is functionally related to a dopamine and an arachidonic acid.

Biological Activity

Potent endogenous cannabinoid and vanilloid receptor agonist, with no action at dopamine receptors. Selective for CB 1 over CB 2 receptors (K i values are 0.25 and 12 μ M respectively), and potent agonist at TRPV1 (VR1) receptors (EC 50 ~ 50 nM). Metabolically stable and competitively inhibits FAAH and anandamide transport. Has cannabinoid and vanilloid actions in vivo . Also available as part of the Endocannabinoid Tocriset™ .
