Abstract

Augmentation of endogenous cannabinoid (eCB) signaling represents an emerging approach to the treatment of affective disorders. Cyclooxygenase-2 (COX-2) oxygenates arachidonic acid to form prostaglandins, but also inactivates eCBs in vitro. However, the viability of COX-2 as a therapeutic target for in vivo eCB augmentation has not been explored. Using medicinal chemistry and in vivo analytical and behavioral pharmacological approaches, we found that COX-2 is important for the regulation of eCB levels in vivo. We used a pharmacological strategy involving substrate-selective inhibition of COX-2 to augment eCB signaling without affecting related non-eCB lipids or prostaglandin synthesis. Behaviorally, substrate-selective inhibition of COX-2 reduced anxiety-like behaviors in mice via increased eCB signaling. Our data suggest a key role for COX-2 in the regulation of eCB signaling and indicate that substrate-selective pharmacology represents a viable approach for eCB augmentation with broad therapeutic potential.

  • When COX-2 is inhibited, AEA and, to a lesser extent, 2-AG accumulate in the brain.

    “When COX-2 is inhibited, AEA and, to a lesser extent, 2-AG accumulate in the brain (Hermanson et al., 2013).”
  • Inhibition of COX-2 causes accumulation of eCBs, increases the tissue content of AEA and to a lesser degree 2-AG, and enhances eCB-mediated retrograde synaptic suppression.

    “inhibition of COX-2 causes accumulation of eCBs as revealed, firstly, by increases in the tissue content of AEA and, to a lesser degree, 2-AG and, secondly, by enhanced eCB-mediated retrograde synaptic suppression - in the form of depolarization-induced suppression of inhibition (DSI) and tonic eCB-suppression of glutamate release (Hermanson et al., 2013; Kim and Alger, 2004; Slanina and Schwe”

  • COX-2 regulates eCB signaling at the synaptic, neurochemical and behavioral level in a manner that only partially overlaps with FAAH and MAGL inhibition, and may have a role in anxiety-like behavior and stress-responsivity.

    “emerging data that one of these pathways, COX-2, regulates eCB signaling at the synaptic, neurochemical and behavioral level in a manner that only partially overlaps with FAAH and MAGL inhibition (Hermanson et al., 2014; Hermanson et al., 2013), but nonetheless may have a role in the mediation of anxiety-like behavior and stress-responsivity (Gamble-George et al., 2016; Hermanson et al., 2013).”

  • The anxiolytic-like effects of LM-4131 in the light-dark exploration test are fully prevented by co-administration of a CB1R antagonist, consistent with eCB-dependency of the COX-2 inhibitor's effects.

    “the anxiolytic-like effects of LM-4131 were fully prevented (in the light-dark exploration test) by co-administration of a CB1R antagonist - consistent with eCB-dependency of the COX-2 inhibitor’s effects (Hermanson et al., 2013).”

  • Systemic administration of LM-4131 decreases mouse anxiety-like behavior in open field, light-dark exploration, and elevated plus-maze assays.

    “systemic administration of the prototypic SSCI, LM-4131, was found to decrease mouse anxiety-like behavior in a range of assays (open field, light-dark exploration, elevated plus-maze) (Hermanson et al., 2013).”

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.
