The effects of treatments with cannabinoid (CB)(1) and cholecystokinin (CCK)(2) receptor agonists and antagonists, as well as compounds that enhance endocannabinoid signaling by inhibiting degradation, e.g., the fatty acid amide hydrolase inhibitor 3'-carbamoyl-biphenyl-3-yl-cyclohexylcarbamate (URB597) or the endocannabinoid reuptake inhibitor (5Z,8Z,11Z,14Z)-N-(3-furanylmethyl)-5,8,11,14-eicosatetraenamide (UCM707), were studied both on spontaneous and electrically evoked [(3) H] GABA efflux from rat cerebral cortex cell cultures.

The cannabinoid receptor 1 (CB (1)) receptor antagonist, rimonabant, but not the cannabinoid receptor 2 (CB (2)) receptor antagonist, SR144528, blocked the antinociceptive phenotype of FAAH (-/-) mice and the analgesic effects of URB597 (3'-carbamoyl-biphenyl-3-yl-cyclohexylcarbamate) or OL-135 (1-oxo-1 [5-(2-pyridyl)-2-yl]-7-phenyl heptane), respective irreversible and reversible FAAH inhibitors, administered to C57BL/6 mice.

BACKGROUND AND PURPOSE: In vitro evidence suggests that metabolism of anandamide by cyclooxygenase-2 (COX-2) may be more important when the primary metabolic pathway [i.e. fatty acid amide hydrolase (FAAH)] is inhibited.
KEY RESULTS: Inhibition of FAAH with URB597 (cyclohexycarbamic acid 3'-carbamoyl-biphenyl-3-yl-ester) augmented the haemodynamic actions of anandamide, but there was no effect of COX-2 inhibition with parecoxib, either in the absence or the presence of URB597.
