Cannabinoid 2 (CB2) receptor agonism reduces lithium chloride-induced vomiting in Suncus murinus and nausea-induced conditioned gaping in rats.
    European journal of pharmacology, 2016, Sep-05, Volume: 786

    We aimed to investigate the potential anti-emetic and anti-nausea properties of targeting the cannabinoid 2 (CB2) receptor. We investigated the effect of the selective CB2 agonist, HU-308, on lithium chloride- (LiCl) induced vomiting in Suncus murinus (S. murinus) and conditioned gaping (nausea-induced behaviour) in rats. Additionally, we determined whether these effects could be prevented by pretreatment with AM630 (a selective CB2 receptor antagonist/inverse agonist). In S. murinus, HU-308 (2.5, 5mg/kg, i.p.) reduced, but did not completely block, LiCl-induced vomiting; an effect that was prevented with AM630. In rats, HU-308 (5mg/kg, i.p.) suppressed, but did not completely block, LiCl-induced conditioned gaping to a flavour; an effect that was prevented by AM630. These findings are the first to demonstrate the ability of a selective CB2 receptor agonist to reduce nausea in animal models, indicating that targeting the CB2 receptor may be an effective strategy, devoid of psychoactive effects, for managing toxin-induced nausea and vomiting.

Attenuation of anticipatory nausea in a rat model of contextually elicited conditioned gaping by enhancement of the endocannabinoid system.
    Psychopharmacology, 2014, Volume: 231, Issue:3

    Enhancement of the endocannabinoid (EC) system may reduce anticipatory nausea (AN).. The experiments evaluated the potential of the dual fatty acid amide hydrolase (FAAH)/monoacylglycerol lipase (MAGL) inhibitor, JZL195, on its own and combined with anandamide (AEA) and 2-arachidonoyl glycerol (2-AG) to reduce contextually elicited gaping, a measure of AN in rats.. Following four context lithium chloride (LiCl) pairings, rats were injected with vehicle (VEH) or JZL195 (10 mg kg(-1), intraperitoneally) 105 min before an injection of VEH, 2-AG (1.25 mg kg(-1)), or AEA (5.0 mg kg(-1)). Fifteen minutes later, all rats were placed in the LiCl-paired context for 5 min and in a different context for a 15-min locomotor test. Whole brains were extracted for EC analysis. The potential of the CB1 antagonist, SR141716, to reverse the suppression of AN by both JZL195 and AEA and of the CB2 antagonist, AM630, to reverse the suppression of AN by JZL195 was then evaluated.. JZL195 suppressed gaping and elevated AEA, palmitoylethanolamine, and oleoylethanolamide. As the suppression of gaping was reversed by SR141716, but not by AM630, the effect was CB1 mediated. The suppressive effect of JZL195 on gaping, as well as elevation of AEA and 2-AG, was amplified by pretreatment with either AEA or 2-AG. On its own, AEA, but not 2-AG, also suppressed gaping-an effect that was also prevented by CB1 antagonism.. JZL195 reduces AN primarily by acting as a FAAH inhibitor, but MAGL inhibition is also indicated.
