WIN 552,12-3 Mesylate is a high affinity cannabinoid agonist.

Novel, low potency CB 2 receptor silent antagonist and CB 1 receptor partial inverse agonist. Competitively antagonizes effects of CP 55,940 (pA 2 = 6.1) and SR 144528 (pEC 50 = 5.3) at CB 2 receptors and acts as a partial inverse agonist at CB 1 receptors (pIC 50 = 5.5). Displays modest activity at human melatonin MT 1 and muscarinic M 4 receptors, but is selective over several other GPCRs.
