We describe the pharmacological and pharmacokinetic profiles of SCH 486757, a nociceptin/orphanin FQ peptide (NOP) receptor agonist that has recently entered human clinical trials for cough. SCH 486757 selectively binds human NOP receptor (K(i)=4.6+/-0.

Article Synopsis
  • Nociceptin/orphanin FQ (N/OFQ) and its receptor, NOP, play a role in inhibiting coughs, leading to interest in SCH 225288, a nonpeptide NOP agonist that could offer new cough treatments.
  • The study first confirmed that SCH 225288 selectively binds to the NOP receptor in human tests, then it assessed its cough-suppressing effects across three different animal models.
  • Results showed that SCH 225288 effectively suppressed cough in guinea pigs, cats, and dogs, and its effects were specifically linked to the NOP receptor rather than classical opioid receptors.

A series of nortropane analogs based on previously reported compound 1 have been synthesized and shown to bind to the nociceptin receptor with high affinity. The synthesis and structure-activity relationships around the C-3 nortropane substitution are described. From the SAR study and hPXR screening effort, compound 15 was identified to possess potent oral antitussive and anxiolytic-like activities in the guinea pig models.

Orphanin FQ/nociceptin (OFQ/N) is the endogenously occurring peptide ligand for the nociceptin opioid receptor (NOP) that produces anxiolytic-like effects in mice and rats. The present study assessed the anxiolytic-like activity of 8-[bis(2-methylphenyl)-methyl]-3-phenyl-8-azabicyclo[3.2.

A series of 4-hydroxy-4-phenylpiperidines have been synthesized and bind to the nociceptin receptor with high affinity. The synthesis and structure-activity relationships at the N-1 and C-4 are described.
