Monoacylglycerol lipase (MAGL), a member of the serine hydrolase family expressed in the brain and peripheral tissue, is a key enzyme in the hydrolysis of monoglycerides, converting 2-arachidonoyl glycerol (2-AG) into arachidonic acid and glycerol. MAGL inhibition has been previously shown to induce anxiolytic and analgesic phenotypes in animal models. Researchers from Janssen Pharmaceutica NV recently reported the discovery of novel noncovalent MAGL inhibitors.
