Monoglyceride lipase (MGL) is a serine hydrolase that terminates the signaling of the primary endocannabinoid, 2-arachidonoyl glycerol (2-AG). Versatile high-throughput screening methods allowing the testing of MGL inhibitors are rare, thereby limiting the development and analysis of novel inhibitors. Here we describe an improved fluorescence-based technique that is capable of determining time- and dose-dependent inhibition of MGL with one or multiple binding sites and, at the same time, is capable of revealing the reversibility of inhibitor binding in a simple kinetic assay format. Known reference compounds as well as novel inhibitors, such as JZL184 and CAY10499, were evaluated for their MGL-binding properties and potency.
