In Vivo Characterization of the Ultrapotent Monoacylglycerol Lipase Inhibitor {4-[bis-(benzo[d][1,3]dioxol-5-yl)methyl]-piperidin-1-yl}(1H-1,2,4-triazol-1-yl)m ethanone (JJKK-048).[Pubmed:27451409]
J Pharmacol Exp Ther. 2016 Oct;359(1):62-72.
Monoacylglycerol lipase (MAGL) is a serine hydrolase that acts as a principal degradative enzyme for the endocannabinoid 2-arachidonoylglycerol (2-AG). In addition to terminating the signaling function of 2-AG, MAGL liberates arachidonic acid to be used as a primary source for neuroinflammatory prostaglandin synthesis in the brain. MAGL activity also contributes to cancer pathogenicity by producing precursors for tumor-promoting bioactive lipids. Pharmacological inhibitors of MAGL provide valuable tools for characterization of MAGL and 2-AG signaling pathways. They also hold great therapeutic potential to treat several pathophysiological conditions, such as pain, neurodegenerative disorders, and cancer. We have previously reported piperidine triazole urea, {4-[bis-(benzo[d][1,3]dioxol-5-yl)methyl]-piperidin-1-yl}(1H-1,2,4-triazol-1-yl)m ethanone (JJKK-048), to be an ultrapotent and highly selective inhibitor of MAGL in vitro. Here, we characterize in vivo effects of JJKK-048. Acute in vivo administration of JJKK-048 induced a massive increase in mouse brain 2-AG levels without affecting brain anandamide levels. JJKK-048 appeared to be extremely potent in vivo. Activity-based protein profiling revealed that JJKK-048 maintains good selectivity toward MAGL over other serine hydrolases. Our results are also the first to show that JJKK-048 promoted significant analgesia in a writhing test with a low dose that did not cause cannabimimetic side effects. At a high dose, JJKK-048 induced analgesia both in the writhing test and in the tail-immersion test, as well as hypomotility and hyperthermia, but not catalepsy.
Mutation of Cys242 of human monoacylglycerol lipase disrupts balanced hydrolysis of 1- and 2-monoacylglycerols and selectively impairs inhibitor potency.[Pubmed:24368842]
Mol Pharmacol. 2014 Mar;85(3):510-9.
Considerable progress has been made in recent years in developing selective, potent monoacylglycerol lipase (MAGL) inhibitors. In the investigations of measures to inhibit this enzyme, less attention has been paid to improving our understanding of its catalytic mechanisms or substrate preferences. In our study, we used site-directed mutagenesis, and we show via versatile activity assays combined with molecular modeling that Cys242 and Tyr194, the two opposing amino acid residues in the catalytic cavity of MAGL, play important roles in determining the rate and the isomer preferences of monoacylglycerol hydrolysis. In contrast to wild-type enzymes that hydrolyzed 1- and 2-monoacylglycerols at similar rates, mutation of Cys242 to alanine caused a significant reduction in overall activity (maximal velocity, Vmax), particularly skewing the balanced hydrolysis of isomers to favor the 2-isomer. Molecular modeling studies indicate that this was caused by structural features unfavorable toward 1-isomers as well as impaired recognition of OH-groups in the glycerol moiety. Direct functional involvement of Cys242 in the catalysis was found unlikely due to the remote distance from the catalytic serine. Unlike C242A, mutation of Tyr194 did not bias the hydrolysis of 1- and 2-monoacylglycerols but significantly compromised overall activity. Finally, mutation of Cys242 was also found to impair inhibition of MAGL, especially that by fluorophosphonate derivatives (13- to 63-fold reduction in potency). Taken together, this study provides new experimental and modeling insights into the molecular mechanisms of MAGL-catalyzed hydrolysis of the primary endocannabinoid 2-arachidonoylglycerol and related monoacylglycerols.
Piperazine and piperidine triazole ureas as ultrapotent and highly selective inhibitors of monoacylglycerol lipase.[Pubmed:23521796]
Chem Biol. 2013 Mar 21;20(3):379-90.
Monoacylglycerol lipase (MAGL) terminates the signaling function of the endocannabinoid, 2-arachidonoylglycerol (2-AG). During 2-AG hydrolysis, MAGL liberates arachidonic acid, feeding the principal substrate for the neuroinflammatory prostaglandins. In cancer cells, MAGL redirects lipid stores toward protumorigenic signaling lipids. Thus MAGL inhibitors may have great therapeutic potential. Although potent and increasingly selective MAGL inhibitors have been described, their number is still limited. Here, we have characterized piperazine and piperidine triazole ureas that combine the high potency attributable to the triazole leaving group together with the bulky aromatic benzodioxolyl moiety required for selectivity, culminating in compound JJKK-048 that potently (IC50 < 0.4 nM) inhibited human and rodent MAGL. JJKK-048 displayed low cross-reactivity with other endocannabinoid targets. Activity-based protein profiling of mouse brain and human melanoma cell proteomes suggested high specificity also among the metabolic serine hydrolases.
