Enhancement of endocannabinoid signaling with JZL184, an inhibitor of the 2-arachidonoylglycerol hydrolyzing enzyme monoacylglycerol lipase, produces anxiolytic effects under conditions of high environmental aversiveness in rats.

“Dysregulation in signaling of the endocannabinoid 2-arachidonoylglycerol (2-AG) is implicated in hyperresponsiveness to stress. We hypothesized that blockade of monoacylglycerol lipase (MGL), the primary enzyme responsible for 2-AG deactivation in vivo, would produce context-dependent anxiolytic effects in rats.

 These data warrant further testing of MGL inhibitors to elucidate the functional role of 2-AG in controlling anxiety and stress responsiveness. Our data further implicate a role for 2-AG in the regulation of emotion and validate MGL as a therapeutic target.”
