JZL 184 is a potent and selective inhibitor of MAGL with IC50 of 8 nM and 4 μM for inhibition of MAGL and FAAH in mouse brain membranes respectively.
IC50 value: 8 nM 
Target: MAGL inhibitor
in vitro: JZL184 prolongs DSE in Purkinje neurons in cerebellar slices and DSI in CA1 pyramidal neurons in hippocampal slices. JZL184 is more potent in inhibiting mouse MAGL than rat MAGL .
in vivo: When administered to mice at 16 mg/kg, intraperitoneally, JZL 184 reduces MAGL activity by 85%, elevates brain 2-AG levels by 8-fold, and elicits analgesic activity in a variety of pain assays that qualitatively mimics direct central cannabinoid (CB1) agonists . Acute administration of JZL184 to FAAH(-/-) mice enhanced the magnitude of a subset of cannabimimetic responses, repeated JZL184 treatment led to tolerance to its antinociceptive effects, cross-tolerance to the pharmacological effects of Δ(9)-tetrahydrocannabinol, decreases in CB1 receptor agonist-stimulated guanosine 5/'-O-(3-[(35)S]thio)triphosphate binding, and dependence as indicated by rimonabant-precipitated withdrawal behaviors, regardless of genotype .

Lack of hippocampal CB1 receptor desensitization by Δ(9)-tetrahydrocannabinol in aged mice and by low doses of JZL 184.Feliszek M,Bindila L,Lutz B,Zimmer A,Bilkei-Gorzo A,Schlicker E, PMID: 26984820 DOI: 10.1007/s00210-016-1226-6 Abstract: Activation of cannabinoid CB1 receptors may offer new therapeutic strategies, but the efficiency of CB1 receptor agonists may be impaired by tolerance development upon prolonged administration. We compared the influence of repeated administration of Δ(9)-tetrahydrocannabinol (THC) 10 mg/kg on the motility and on basal and CB1 receptor-stimulated (35)S-GTPγS binding of adolescent and aged mice. Moreover, we determined the influence of JZL 184 (which inhibits the 2-arachidonoylglycerol, 2-AG, degrading enzyme monoacylglycerol lipase, MAGL) on (35)S-GTPγS binding and 2-AG levels of young adult mice. Mouse motility was tested in the open field. (35)S-GTPγS binding was studied in hippocampal membranes. THC and CP 55,940 were used as cannabinoid agonists in the behavioural and biochemical studies, respectively. 2-AG levels were quantified by liquid chromatography-multiple reaction monitoring. The THC (10 mg/kg)-induced hypomotility was stronger in untreated than in THC-pretreated adolescent mice but similar in both treatment groups of aged mice. Basal and stimulated (35)S-GTPγS binding was decreased in membranes from THC-pretreated adolescent but not affected in membranes from aged mice. Treatment of young adult mice with JZL 184 (4, 10 and 40 mg/kg) for 14 days did not affect basal binding. Stimulated binding tended to be decreased by 25 % only in mice treated with JZL 184 (40 mg/kg). Hippocampal 2-AG level was increased by JZL 184 at 40 and 10 but not affected at 4 mg/kg. In conclusion, CB1 receptor tolerance does not occur in aged mice pretreated with THC and in young adult mice treated with a low dose of the MAGL inhibitor JZL 184.
