WIN 55,212-2 Mesylate is a potent aminoalkylindole cannabinoid (CB) receptor agonist with Ki values of 62.3nM and 3.3nM for human recombinant CB1 and CB2 receptors, respectively[1]. WIN 55,212-2 Mesylate produces antinociceptive effects through a peripheral mechanism of action[2]. WIN 55,212-2 Mesylate has vasorelaxant effects[3].
In vitro, treatment of rat dorsal root ganglion (DRG) neurons with WIN 55,212-2 Mesylate (100-400ng/mL) for 25h abolished TNF-α-induced nNOS expression and inhibited p38 MAPK activity in DRG neurons in a concentration- and time-dependent manner[4]. WIN 55,212-2 Mesylate (0.5-8μM) treated primary human chondrocytes for 24h, concentration-dependently inhibited IL-1β-stimulated aggrecanase-1 (ADAMTS-4) activity and syndecan-1 protein expression levels, but not ADAMTS-4 protein expression levels[5].
In vivo, WIN 55,212-2 Mesylate (5-20mg/kg) treated Swiss mice by intraperitoneal injection increased the threshold of maximum electric shock (MEST)-induced epilepsy in a dose-dependent manner[6]. WIN 55,212-2 Mesylate (1.25-15mg/kg) treated Swiss mice by intraperitoneal injection, administered 20 minutes before the acute heat pain test, prolonged the latency of the mice's first pain response in a dose-dependent manner[7].
