Abstract: The disclosure provides methods of using certain morphinans of Formula (I) that are partial kappa opioid receptor agonists, weak mu opioid receptor agonists, and partial or weak delta opioid receptor agonists in the treatment of kappa opioid receptor-associated diseases and conditions. The disclosure provides methods of treating pruritus, acute seizures, and seizure disorders. The disclosure also provides a method of treating cocaine addiction by administering a particular compound of Formula I, PPL-103, to a cocaine addicted patient.

Abstract: The present disclosure provides compositions including a ?4?2 nAChR antagonist, pharmaceutical compositions including a ?4?2 nAChR antagonist, methods of making the compositions or pharmaceutical compositions, methods of treatment of a condition (e.g., nicotine addiction) or disease, methods of treatment using compositions or pharmaceutical compositions, and the like. Embodiments of the present disclosure can be used to reduce nicotine cravings and treat nicotine addiction. The compositions have selective affinity for the ?4?2 receptor, which appears to be involved in nicotine dependence.

Abstract: Novel piperidyl indolinone compounds are provided that are useful as agonist and antagonist ligands of the nociceptin receptor.

Abstract: A novel atrial peptide-degrading enzyme (ADE) is provided in isolated, purified form. The enzyme has a molecular weight of approximately 160,000 Daltons as measured by gel filtration chromatography, and is effective to cleave atrial peptides such as APII, APIII and ANF. Also provided are novel compounds useful as inhibitors of the enzyme and thus useful as blood pressure lowering agents, pharmaceutical compositions containing the inhibitors, and methods of using the inhibitors.
