描述 | Monoacylglycerol lipase (MAGL) is a key enzyme in the human endocannabinoid system. It is also the main enzyme responsible for the conversion of 2-arachidonoyl glycerol (2-AG) to arachidonic acid (AA), a precursor of prostaglandin synthesis. The inhibition of MAGL activity would be beneficial for the treatment of a wide range of diseases, such as inflammation, neurodegeneration, metabolic disorders and cancer[3]. JZL 184 is a potent, selective and irreversible MAGL inhibitor that blocks 2-Arachidonoylglycerol (2-AG) hydrolysis in brain membranes (IC50 of 8 nM). JZL 184 displays >300-fold selectivity for MAGL over FAAH. JZL 184 displays IC50 values of 8 nM and 4 μM for blockade of 2-AG and oleamide (FAAH substrate) hydrolysis in brain membranes, respectively. Comparable inhibitory effects are observed with recombinant MAGL and FAAH when expressed in COS7 cells. JZL 184 (4-40 mg/kg; intraperitoneal injection; once; C57Bl/6 mice) treatment produces a rapid and sustained blockade of brain 2-AG hydrolase activity in mice, resulting in 8-fold elevations in endogenous 2-AG levels that are maintained for at least 8 h. JZL 184-treated mice shows a remarkable array of CB1-dependent behavioral effects, including analgesia, hypomotility, and hypothermia[4]. 8 mg/kg JZL-184 significantly increased the levels of 2-AG in the auditory cortex of both Fmr1 KO and WT mice 4 h post-treatment. A reduction in the abnormally enhanced baseline gamma-band power in Fmr1 KO mice and significantly improved evoked synchronization to auditory stimuli in the gamma-band range post-JZL-184 treatment. JZL-184 treatment also ameliorated anxiety-like and hyperactivity phenotypes in Fmr1 KO mice[5]. JZL 184 prolongs depolarization-induced suppression of excitation (DSE) in Purkinje neurons in cerebellar slices and DSE inhibition (DSI) in CA1 pyramidal neurons in hippocampal slices. JZL 184 produces greater enhancement of DSE/DSI in mouse neurons than that in rat neurons[6]. |
