JZL184

JZL184 is a potent and selective inhibitor of MAGL [1].

Monoacylglycerol lipase (MAGL) is a membrane-associated member of the serine hydrolase superfamily and hydrolyzes endocannabinoid 2-arachidonoylglycerol (2-AG) and intracellular triglyceride stores.

JZL184 is a potent and selective MAGL inhibitor. In cerebellar Purkinje neurons, JZL184 (40-120 min) prolonged depolarization-induced suppression of excitation (DSE) in a dose-dependent way, which was mediated by CB1 receptor. In hippocampal CA1 pyramidal neurons, JZL184 (100 nM) significantly prolonged depolarization-induced suppression of inhibition (DSI), which was mediated by CB1 receptor activation. In mouse cerebellar slices, JZL184 (100 nM) significantly enhanced 2-AG (10 μM)-induced depression of EPSCs in Purkinje neurons. These results suggested that MAGL is the primary mechanism by which 2-AG is metabolized [1].

In mice, JZL184 inhibited 2-AG hydrolysis with IC50 value of 8 nM and increased brain 2-AG by 8-fold. The JZL184-treated mice exhibited CB1-dependent behaviors including analgesia, hypomotility and hypothermia [2]. In rats, JZL184 (8 mg/kg) exhibited anxiolytic-like effects via inhibition of MGL mediated 2-AG hydrolysis under high levels of environmental aversiveness [3]. In rats, JZL184 produced antinociception with ED50 values of 0.06 and 0.03 μM in the early phase and the late phase of formalin pain, respectively [4].
