Abstract

We need better medicines to control acute and chronic pain. Fatty acid amide hydrolase (FAAH) and soluble epoxide hydrolase (sEH) catalyze the deactivating hydrolysis of two classes of bioactive lipid mediators--fatty acid ethanolamides (FAEs) and epoxidized fatty acids (EpFAs), respectively--which are biogenetically distinct but share the ability to attenuate pain responses and inflammation. In these experiments, we evaluated the antihyperalgesic activity of small-molecule inhibitors of FAAH and sEH, administered alone or in combination, in two pain models: carrageenan-induced hyperalgesia in mice and streptozocin-induced allodynia in rats. When administered separately, the sEH inhibitor 1-trifluoromethoxyphenyl-3-(1-propionylpiperidine-4-yl)urea (TPPU) and the peripherally restricted FAAH inhibitor URB937 were highly active in the two models. The combination TPPU plus URB937 was markedly synergistic, as assessed using isobolographic analyses. The results of these experiments reveal the existence of a possible functional crosstalk between FAEs and EpFAs in regulating pain responses. Additionally, the results suggest that combinations of sEH and FAAH inhibitors might be exploited therapeutically to achieve greater analgesic efficacy.

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.
