Abstract:
:Following the cloning of the classical opioid receptors (mu, delta and kappa), the opioid receptor like-1 (ORL-1) was identified as a G-protein coupled receptor (GPCR) with 65% structure homology to the other members of the opioid family. Its endogenous ligand nociception/orphanin FQ (N/OFQ) was discovered shortly thereafter, becoming the subject of investigation in numerous studies. Since activation of the ORL-1 receptor by N/OFQ leads to G alpha(i)-coupling and signal transduction similar to that of opioid receptors, N/OFQ was thought to have a role in pain modulation, similar to that of the endogenous opioids. Surprisingly, studies characterizing N/OFQ's effects on pain transmission yielded conflicting results, attributing to N/OFQ both pronociceptive and antinociceptive actions, depending on doses and routes of administration as well as species and sex of the subjects. With the development of selective and potent ORL-1 antagonists, many scientists believed these contradicting actions would be elucidated. Here we review the recent literature reporting the use of novel ORL-1 antagonists, both peptide and non-peptide, in different models of pain and discuss their use as research tools or potential drug candidates.
