Endogenous agonist for the GPR55 and CB1 receptors (EC50 values are 10 and 37 nM respectively) that displays selectivity over CB2 receptors (Ki values are 21.2 nM and > 3mM at CB1 and CB2 respectively). Causes sedation, hypothermia, intestinal immobility and mild antinociception in vivo. Attenuates sensory neurotransmission in rat mesenteric arteries via GPR55. Also available as part of the Endocannabinoid Tocriset™.
