PB-22, a recreational “designer drugs”, is a cannabimimetic agent, it is a full agonist of cannabinoid receptors. PB-22 has an EC50 of 5.1 nM for human CB1 receptors, and 37 nM for human CB2 receptors. PB-22 produces bradycardia and hypothermia in rats at doses of 0.3–3 mg/kg, suggesting potent cannabinoid-like activity. PB-22 was designated as a Schedule I controlled substance in the United States.
