Kinase experiment: | Samples containing either URB602 (300 μM), MGL (1.4 pM), or both URB602 and MGL are incubated at 37°C for 30 min in assay buffer. At various time points, the reaction is stopped with an equal volume of ice-cold methanol and directly analyzed in positive ionization mode by LC/MS. A SB-CN column (150×2.1 mm i.d., 5 μm) eluted is used with a linear gradient of methanol in water containing 0.25% acetic acid and 5 mM ammonium acetate (from 60% to 100% of methanol in 8 min) at a flow rate of 0.5 mL/min with column temperature at 50°C. Capillary voltage is set at 4 kV and fragmentor voltage is 100V. Nebulizer pressure is set at 60 psi. N2 is used as drying gas at a flow rate of 13 liters/min and a temperature of 350°C. ESI is in the positive mode and a full scan spectrum is acquired from m/z 100 to 600. Extracted ion chromatograms are used to quantify URB602 ([M+H]+, m/z 296)[2]. |
Animal experiment: | Mice[3] Male C57BL/6 mice (5-6 wk; 20-26 g) or female CB1-/- mice (8 wk; 18-22 g) on a C57BL/6 background are used. After an overnight fasting period (water ad libitum), a marker is administered orally to assess upper GI transit, as described in detail by others. At 30 min after intraperitoneal (ip) administration of URB602 (20 or 40 mg/kg) or vehicle (10% DMSO/Tween 80 in saline), an oral gavage of 200 μL of an Evans blue marker (5% Evans blue, 5% gum arabic) is administered. After 15 min animals are killed by cervical dislocation and the intestine from the region of the pyloric sphincter to the ileocecal junction is immediately removed. The distance traveled by the marker is measured in centimeters and expressed as a percentage of the total length of the small intestine. Rats[4] Three hundred and seven adult male Sprague-Dawley rats weighing 275-350 g, at the time of testing, are used. In a first study, the dose-response curves for JZL184 and URB602 are determined using the AUC of Phase 1 or Phase 2 pain behaviour. In a second study, the antinociceptive effects of JZL184 (300 μg) and URB602 (600 μg) are evaluated following injection in the paw, ipsilateral or contralateral to formalin, to exclude the possibility that systemic leakage contributed to the pattern of results obtained. In a third study, antinociceptive effects of ED50 doses of JZL184 (0.03 μg i.paw) or URB602 (66 μg i.paw), in combination with 2-AG (ED50 dose of 1 μg i.paw), are quantified to evaluate the presence of additive or synergic effects of these drugs. In a fourth study, antinociceptive effects of JZL184 (at 10 μg i.paw, an analgesic dose) are studied in the presence or absence of either AM251 or AM630 to determine whether these effects are mediated through CB1 and/or CB2 receptors. The CB1 receptor antagonist AM251 exhibits 306-fold selectivity for CB1 over CB2 receptors, whereas the CB2 receptor antagonist AM630 exhibits 70-165-fold selectivity for CB2 over CB1 receptors. The doses employed (AM251 at 80 μg i.paw and AM630 at 25 μg i.paw) are those which block peripheral antinociceptive effects of URB602 in Wistar rats. For the first study (n=4-6 per group for URB602 and n=6-8 per group for JZL184) and for all the other behavioural studies (n=6 per group), drugs, administered either alone or in combination, are dissolved in the same total volume (50 μL) and injected into the right hind paw. Preliminary experiments (n=8 per group; data not shown) confirmed that formalin-induced pain behaviour did not change following intra-paw administration of either vehicle (PEG 300: Tween 80 in a 4:1 ratio or DMSO: ethanol: cremophor: 0.9% saline in a 1:1:1:17 ratio]. |

URB602 inhibits monoacylglycerol lipase and selectively blocks 2-arachidonoylglycerol degradation in intact brain slices
Chem Biol 2007 Dec;14(12):1357-65.PMID:18096504DOI:10.1016/j.chembiol.2007.10.017.
The N-aryl carbamate URB602 (biphenyl-3-ylcarbamic acid cyclohexyl ester) is an inhibitor of monoacylglycerol lipase (MGL), a serine hydrolase involved in the biological deactivation of the endocannabinoid 2-arachidonoyl-sn-glycerol (2-AG). Here, we investigated the mechanism by which URB602 inhibits purified recombinant rat MGL by using a combination of biochemical and structure-activity relationship (SAR) approaches. We found that URB602 weakly inhibits recombinant MGL (IC(50) = 223 +/- 63 microM) through a rapid and noncompetitive mechanism. Dialysis experiments and SAR analyses suggest that URB602 acts through a partially reversible mechanism rather than by irreversible carbamoylation of MGL. Finally, URB602 (100 microM) elevates 2-AG levels in hippocampal slice cultures without affecting levels of other endocannabinoid-related substances. Thus, URB602 may provide a useful tool by which to investigate the physiological roles of 2-AG and explore the potential interest of MGL as a therapeutic target.
Effects of monoacylglycerol lipase inhibitor URB602 on lung ischemia-reperfusion injury in mice
Biochem Biophys Res Commun 2018 Nov 30;506(3):578-584.PMID:30366666DOI:10.1016/j.bbrc.2018.10.098.
Lung ischemia-reperfusion injury (LIRI) is a common and severe postoperative pathologic complication that often occurs when the oxygen supply disrupted to the lung tissue fallowed by reperfusion period, in most cases after lung transplantation and cardiopulmonary bypass. Endocannabinoids such as 2-arachidonoylglycerol (2-AG) have very important role as regulators of inflammation. Monoacylglycerol lipase (MAGL) is the main 2-AG-degrading enzyme, and the downstream metabolites of 2-AG play a role in the inflammation. Ischemia reperfusion (IR) was induced by clamping the left pulmonary hilum for 60 min, followed by 120 min of reperfusion in male C57BL/6 mice. Effects of URB602, a MAGL inhibitor, were evaluated in a preventive or therapeutic regimen (5 min before ischemia or reperfusion, respectively). Oxygenation index, wet-to-dry weight ratio and lung injury score were analyzed. Endocannabinoids including 2-AG, anandamide (AEA) and arachidonic acid (AA) levels, metabolites such as Prostaglandin I2 (PGI2), Thromboxane B2 (TXB2) and Leukotrienes B4 (LTB4) and inflammatory markers (Interleukin 6 (IL-6) andTumor necrosis factor-α (TNF-α)) in lung tissues were measured by using mass spectrometry or ELISA analyses. We found that IR increased the wet-to-dry weight ratio of lung and lung injury score and decreased oxygenation index as compared to the sham group. Moreover, treatment with URB602 in preventive or therapeutic regimen reduced the wet-to-dry weight ratio and lung injury score while increased oxygenation index when compared with the IR group, with a more improvement in the preventive regimen group. In addition, treatment with URB602 before ischemia increased 2-AG level but decreased metabolites (AA, PGI2, TXB2, LTB4) and inflammatory markers (IL-6, TNF-α). Thus, our study demonstrated that a pretreatment with URB602 significantly reduced IR-induced lung injury and inflammation. URB602 inhibited LIRI and inflammation by increasing 2-AG level and reducing downstream metabolites from AA to PGI2, TXB2 and LTB4 in lung tissues.
Monoacylglycerol Lipase Inactivation by Using URB602 Mitigates Myocardial Damage in a Rat Model of Cardiac Arrest
Crit Care Med 2019 Feb;47(2):e144-e151.PMID:30431495DOI:10.1097/CCM.0000000000003552.
Objectives: Monoacylglycerol lipase participates in organ protection by regulating the hydrolysis of the endocannabinoid 2-arachidonoylglycerol. This study investigated whether blocking monoacylglycerol lipase protects against postresuscitation myocardial injury and improves survival in a rat model of cardiac arrest and cardiopulmonary resuscitation. Design: Prospective randomized laboratory study. Setting: University research laboratory. Subjects: Male Sprague-Dawley rat (n = 96). Interventions: Rats underwent 8-minute asphyxia-based cardiac arrest and resuscitation. Surviving rats were randomly divided into cardiopulmonary resuscitation + URB602 group, cardiopulmonary resuscitation group, and sham group. One minute after successful resuscitation, rats in the cardiopulmonary resuscitation + URB602 group received a single dose of URB602 (5 mg/kg), a small-molecule monoacylglycerol lipase inhibitor, whereas rats in the cardiopulmonary resuscitation group received an equivalent volume of vehicle solution. The sham rats underwent all of the procedures performed on rats in the cardiopulmonary resuscitation and cardiopulmonary resuscitation + URB602 groups minus cardiac arrest and asphyxia. Measurements and main results: Survival was recorded 168 hours after the return of spontaneous circulation (n = 22 in each group). Compared with vehicle treatment (31.8%), URB602 treatment markedly improved survival (63.6%) 168 hours after cardiopulmonary resuscitation. Next, we used additional surviving rats to evaluate myocardial and mitochondrial injury 6 hours after return of spontaneous circulation, and we found that URB602 significantly reduced myocardial injury and prevented myocardial mitochondrial damage. In addition, URB602 attenuated the dysregulation of endocannabinoid and eicosanoid metabolism 6 hours after return of spontaneous circulation and prevented the acceleration of mitochondrial permeability transition 15 minutes after return of spontaneous circulation. Conclusions: Monoacylglycerol lipase blockade may reduce myocardial and mitochondrial injury and significantly improve the resuscitation effect after cardiac arrest and cardiopulmonary resuscitation.
Lack of selectivity of URB602 for 2-oleoylglycerol compared to anandamide hydrolysis in vitro
Br J Pharmacol 2007 Jan;150(2):186-91.PMID:17143303DOI:10.1038/sj.bjp.0706971.
Background and purpose: Two compounds, URB602 and URB754, have been reported in the literature to be selective inhibitors of monoacylglycerol lipase, although a recent study has questioned their ability to prevent 2-arachidonoyl hydrolysis by brain homogenates and cerebellar membranes. In the present study, the ability of these compounds to inhibit monoacylglycerol lipase and fatty acid amide hydrolase has been reinvestigated. Experimental approach: Homogenates and cell lines were incubated with test compounds and, thereafter, with either [(3)H]-2-oleoylglycerol or [(3)H]-anandamide. Labelled reaction products were separated from substrate using chloroform: methanol extraction. Key results: In cytosolic fractions from rat brain, URB602 and URB754 inhibited the hydrolysis of 2-oleoylglycerol with IC(50) values of 25 and 48 microM, respectively. Anandamide hydrolysis by brain membranes was not sensitive to URB754, but was inhibited by URB602 (IC(50) value 17 microM). Hydrolysis of 2-oleoylglycerol by human recombinant monoacylglycerol lipase was sensitive to URB602, but not URB754. The lack of selectivity of URB602 for 2-oleoylglycerol compared to anandamide hydrolysis was also observed for intact RBL2H3 basophilic leukaemia cells. C6 glioma expressed mRNA for monoacylglycerol lipase, and hydrolyzed 2-oleoylglycerol in a manner sensitive to inhibition by methyl arachidonoyl fluorophosphonate but not URB754 or URB597. MC3T3-E1 mouse osteoblastic cells, which did not express mRNA for monoacylglycerol lipase, hydrolyzed 2-oleoylglycerol in the presence of URB597, but the hydrolysis was less sensitive to methyl arachidonoyl fluorophosphonate than for C6 cells. Conclusions and implications: The data demonstrate that the compounds URB602 and URB754 do not behave as selective and/or potent inhibitors of monoacylglycerol lipase.
The inhibition of monoacylglycerol lipase by URB602 showed an anti-inflammatory and anti-nociceptive effect in a murine model of acute inflammation
Br J Pharmacol 2007 Nov;152(5):787-94.PMID:17700715DOI:10.1038/sj.bjp.0707425.
Background and purpose: 2-arachidonoylglycerol (2-AG) is an endocannabinoid whose hydrolysis is predominantly catalysed by the enzyme monoacylglycerol lipase (MAGL). The development of MAGL inhibitors could offer an opportunity to investigate the anti-inflammatory and anti-nociceptive role of 2-AG, which have not yet been elucidated. On these bases, URB602, a MAGL inhibitor, was tested in a murine model of inflammation/inflammatory pain. Experimental approach: Acute inflammation was induced by intraplantar injection of lambda-carrageenan into mice. The highest dose to be employed has been selected performing the tetrad assays for cannabimimetic activity in mice. URB602 anti-inflammatory and anti-nociceptive efficacy (assessed by plethysmometer and plantar test, respectively) was evaluated both in a preventive regimen (drug administered 30 min before carrageenan) and in a therapeutic regimen (URB602 administered 30 min after carrageenan). To elucidate the cannabinoid receptor involvement, rimonabant and SR144528, CB1 and CB2 selective antagonists, respectively, were given 15 min before URB602. Key results: Systemic administration of URB602 elicited a dose-dependent anti-oedemigen and anti-nociceptive effect that was reversed exclusively by the CB2 receptor antagonist. The efficacy of URB602 persisted also when the compound was administered in a therapeutic regimen, suggesting the ability of URB602 to improve established disease. Conclusions and implications: The present report highlighted the ability of the selective MAGL inhibitor, URB602, to prevent and treat an acute inflammatory disease without producing adverse psychoactive effects. The data presented herein also contributed to clarify the physiological role of 2-AG in respect to inflammatory reactions, suggesting its protective role in the body.
