Abstract

Aim The present study tested whether the selective monoacylglycerol lipase (MAGL) inhibitor JZL184 would reduce allodynia and paw edema in the carrageenan test.Main methods The anti-edematous and anti-allodynic effects of JZL184 were compared to those of PF-3845, an inhibitor of fatty acid amide hydrolase (FAAH), and diclofenac, a non-selective cyclooxygenase inhibitor. Cannabinoid receptor involvement in the anti-edematous and anti-allodynic effects of JZL184 was evaluated by administration of the respective CB1 and CB2 receptor antagonists rimonabant and SR144528 as well as with CB1(-/-) and CB2(-/-) mice. JZL184 (1.6, 4, 16, or 40mg/kg) was administered for six days to assess tolerance.Key findings JZL184 administered before or after carrageenan significantly attenuated carrageenan-induced paw edema and mechanical allodynia. Complementary genetic and pharmacological approaches revealed that the anti-allodynic effects of JZL184 required both CB1 and CB2 receptors, but only CB2 receptors mediated its anti-edematous actions. Importantly, both the anti-edematous and anti-allodynic effects underwent tolerance following repeated injections of high dose JZL184 (16 or 40mg/kg), but repeated administration of low dose JZL184 (4mg/kg) retained efficacy.Significance These results suggest that the MAGL inhibitor JZL184 reduces inflammatory nociception through the activation of both CB1 and CB2 receptors, with no evidence of tolerance following repeated administration of low doses.

  • Pharmacological inhibition or genetic deletion of FAAH attenuates carrageenan-induced inflammation as well as mechanical allodynia and thermal hyperalgesia.

    “For example, pharmacological inhibition or genetic deletion of FAAH attenuates carrageenan-induced inflammation as well as mechanical allodynia and thermal hyperalgesia (increased sensitivity to a noxious heat stimuli) (Ghosh et al, 2013;Karbarz et al, 2009;Lichtman et al, 2004).”
  • Inhibition of MAGL attenuates carrageenan-induced acute paw edema and inflammatory pain.

    “Similarly, inhibition of MAGL, the primary catabolic enzyme of 2-AG (Blankman et al, 2007), attenuates carrageenan-induced, acute paw edema and inflammatory pain (Comelli et al, 2007;Ghosh et al, 2013;Ignatowska-Jankowska et al, 2014).”
  • The selective MAGL inhibitors JZL184 and KML129 attenuate carrageenan-induced mechanical allodynia through CB1 and CB2 receptor-dependent mechanisms, but only CB2 receptors mediate the anti-edematous effects of these inhibitors.

    “The selective MAGL inhibitors JZL184 and KML129 attenuate carrageenan-induced mechanical allodynia through CB 1 and CB 2 receptor-dependent mechanisms, but only CB 2 receptors mediate the antiedematous effects of these inhibitors (Ghosh et al, 2013;Ignatowska-Jankowska et al, 2014).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
