(±)-WIN 55,212 (mesylate)

(±)-WIN 55,212 is a racemic mixture of the cannabinoid (CB) receptor 1 (CB1) and CB2 agonist (+)-WIN 55,212-2 (Cay-10009023) and the CB2 neutral antagonist (-)-WIN 55,212-3 (Cay-12022). It inhibits electrically induced contractions in mouse vas deferens preparations (IC50 = 0.006 µM) and reduces prostaglandin (PG) synthesis by 35% in mouse brain microsomes when used at a concentration of 30 µM. (±)-WIN 55,212 decreases acetylcholine-induced writhing in mice with an ED50 value of 0.25 mg/kg. It induces hypolocomotion, analgesia, hypothermia, and catalepsy in mice (ED50s = 1.09, 0.5, 3.01 and 6.8 mg/kg, respectively).Formal Name: [2,3-dihydro-5-methyl-3-(4-morpholinylmethyl)pyrrolo[1,2,3-de]-1,4-benzoxazin-6-yl]-1-naphthalenyl-methanone, methanesulfonate.
