Purity >98% by HPLC. A neurobehaviorally inactive Cannabinoid that acts as a selective agonist for an as-yet-unidentified endothelial receptor for Anandamide. Does not bind to CB1 receptors, yet causes SR141716A-sensitive hypotension and mesenteric vasodilation in wild-type mice and in mice lacking CB1 receptors or both CB1 and CB2 receptors. Stimulates endothelial cell migration via a Gi/Go-coupled receptor distinct from CB1, CB2 or EDG-;
