Exogenous cannabinoid receptor agonists are clinically effective for treating chronic pain but frequently cause side effects in the central nervous system. Fatty acid amide hydrolase (FAAH) is a primary catabolic enzyme for anandamide, an endogenous cannabinoid agonist. 3-Pyridyl 4-(phenylcarbamoyl)piperidine-1-carboxylate (ASP8477) is a potent and selective FAAH inhibitor that is orally active and able to increase the brain anandamide level and is effective in rat models of neuropathic and osteoarthritis pain without causing motor coordination deficits. In the present study, we examined the pharmacokinetics and pharmacodynamics, analgesic spectrum in pain models, and the anti-nociceptive mechanism of ASP8477. Single and four-week repeated oral administration of ASP8477 ameliorated mechanical allodynia in spinal nerve ligation rats with similar improvement rates. Further, single oral administration of ASP8477 improved thermal hyperalgesia and cold allodynia in chronic constriction nerve injury rats. ASP8477 also restored muscle pressure thresholds in reserpine-induced myalgia rats. This analgesic effect of ASP8477 persisted for at least 4 h, consistent with the inhibitory effect observed in an ex vivo study using rat brain as well as the increasing effect on oleoylethanolamide and palmitoylethanolamide levels but not the ASP8477 concentration in rat brain. ASP8477 also improved α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA)-, N-methyl-D-aspartic acid (NMDA)-, prostaglandin E-, prostaglandin F-, and bicuculline-induced allodynia in mice, showing broader analgesic spectra than existing drugs. In contrast, however, ASP8477 did not affect acute pain. These results indicate that the FAAH inhibitor ASP8477 exerts analgesic effects on neuropathic and dysfunctional pain, and its pharmacological properties are suitable for use in treating chronic pain.
