Monoacylglycerol lipase (MAGL) is responsible for signal termination of 2-arachidonoylglycerol (2-AG), an endocannabinoid neurotransmitter endowed with several physiological effects. Previously, we showed that the arylthioamide scaffold represents a privileged template for designing MAGL inhibitors. A series of 37 compounds resulting from pharmacomodulations around the arylthioamide template were synthesized and tested to evaluate their inhibitory potential on MAGL activity as well as their selectivity over fatty acid amide hydrolase (FAAH), another endocannabinoid-hydrolyzing enzyme. We have identified 2,4-dinitroaryldithiocarbamate derivatives as a novel class of MAGL inhibitors. Among the synthesized compounds, we identified [2,4-dinitrophenyl-4-(4-tert- butylbenzyl)piperazine-1-carbodithioate] (CK37), as the most potent MAGL inhibitor within this series (IC50 = 154 nM). We have also identified [2,4-dinitrophenyl-4-benzhydrylpiperazine-1-carbodithioate] (CK16) as a selective MAGL inhibitor. These compounds are irreversible MAGL inhibitors that probably act by interacting with Cys208 or Cys242 and Ser122 residues of the enzyme. Moreover, CK37 is able to raise 2-arachidonoylglycerol (2-AG) levels in intact cells.
