(−)-CP 55,940 is a potent and non-selective cannabinoid (CB) receptor agonist with Ki values of 0.5 to 5 and 0.69 to 2.8 nM for CB1 and CB2 receptors, respectively.1 It is more potent than Δ9-THC (Item Nos. 12068 | ISO60157) in both behavioral tests and in receptor binding assays.2 In vivo, (−)-CP 55,940 administered intraperitoneally (0.3-3 mg/kg) or as an aerosol (0.72-72 mg/ml), suppresses locomotor activity, increases tail flick latency in a hot plate test for analgesia, and decreases body temperature in mice in a dose-dependent manner.3 Subchronic administration of (−)-CP 55,940 (0.03 mg/kg) also reduces body weight loss and running wheel activity in a rat model of anorexia nervosa.4
