(2E,4E)-N-[2-(3,4-dimethoxyphenyl)ethyl]dodeca-2,4-dienamide

説明WOBE437 is a potent endocannabinoid uptake inhibitor with IC50 values of 10 and 283 nM for arachidonoyl ethanolamide (AEA; ) and 2-arachidonoyl glycerol (2-AG; ) uptake, respectively, in U937 cells. It is greater than 1,000-fold selective for endocannabinoid transporters over fatty acid amide hydrolase (FAAH; ) and the 2-AG hydrolyzing enzymes MAGL, ABHD6, and ABHD12. WOBE437 inhibits AEA uptake in FAAH-deficient HMC-1 human mast cells and Neuro2a mouse neuroblastoma cells (IC50s = 137 and 55 nM, respectively) and reduces AEA uptake by 50% in rat cortical neurons when used at a concentration of 1 μM. It also reduces 2-AG uptake by 40% in Neuro2a cells at a concentration of 5 μM. In vivo, WOBE437 increases AEA and 2-AG levels by 1.5-fold in mouse brain but not peripheral tissues after intraperitoneal administration of a 10 mg/kg dose for seven days. WOBE437 (10 mg/kg) also induces a typical tetrad of hypothermia, catalepsy, analgesia, and hypomotility in mice, indicating it also acts as an indirect cannabinoid (CB) receptor 1 agonist.
