Prisinzano Date approved: July 18, 2012 ii ABSTRACT Kappa opioid (KOP) receptors have been suggested as an alternative target to the mu opioid (MOP) receptor for the treatment of pain because KOP activation is associated with fewer negative side-effects (respiratory depression, constipation, tolerance, and dependence). The KOP receptor has also been implicated in several abuse-related effects in the central nervous system (CNS). KOP ligands have been investigated as pharmacotherapies for drug abuse; KOP agonists have been shown to modulate dopamine concentrations in the CNS as well as attenuate the self-administration of cocaine in a variety of species, and KOP antagonists have potential in the treatment of relapse. One drawback of current opioid ligand investigation is that many compounds are based on the morphine scaffold and thus have similar properties, both positive and negative, to the parent molecule. Thus there is increasing need to discover new chemical scaffolds with opioid receptor activity. -

Amara, National Institutes of Health, Bethesda, MD, and approved April 14, 2020 (received for review January 20, 2020) Opioids, such as morphine and fentanyl, are widely used for the possibility that endogenous opioid peptides could vary in this treatment of severe pain; however, prolonged treatment with manner as well (13). these drugs leads to the development of tolerance and can lead to For opioid receptors, studies showed that mice lacking opioid use disorder. The “Opioid Epidemic” has generated a drive β-arrestin2 exhibited enhanced and prolonged morphine-mediated for a deeper understanding of the fundamental signaling mecha- antinociception, and a reduction in side-effects, such as devel- nisms of opioid receptors. It is generally thought that the three opment of tolerance and acute constipation (15, 16). This led to types of opioid receptors (μ, δ, κ) are activated by endogenous studies examining whether μOR agonists exhibit biased signaling peptides derived from three different precursors: Proopiomelano- (17–20), and to the identification of agonists that preferentially cortin, proenkephalin, and prodynorphin. -

Thompson1, Xi-Ping Huang2, F. Ivy Carroll3, S. Wayne Mascarella3, Richard B. Westkaemper4, Philip D. Mosier4, Bryan L. Roth2, Vadim Cherezov1 & Raymond C. Stevens1 Opioid receptors mediate the actions of endogenous and exogenous opioids on many physiological processes, including the regulation of pain, respiratory drive, mood, and—in the case of k-opioid receptor (k-OR)—dysphoria and psychotomimesis. Here we report the crystal structure of the human k-OR in complex with the selective antagonist JDTic, arranged in parallel dimers, at 2.9 A˚ resolution. The structure reveals important features of the ligand-binding pocket that contribute to the high affinity and subtype selectivity of JDTic for the human k-OR. Modelling of other important k-OR-selective ligands, including the morphinan-derived antagonists norbinaltorphimine and 59-guanidinonaltrindole, and the diterpene agonist salvinorin A analogue RB-64, reveals both common and distinct features for binding these diverse chemotypes. Analysis of site-directed mutagenesis and ligand structure–activity relationships confirms the interactions observed in the crystal structure, thereby providing a molecular explanation for k-OR subtype selectivity, and essential insights for the design of compounds with new pharmacological properties targeting the human k-OR. The four opioid receptors, m, d, k and the nociceptin/orphanin FQ antidepressants, anxiolytics and anti-addiction medications14, whereas peptide receptor, belong to the class A (rhodopsin-like) c subfamily of a widely abused, naturally occurring hallucinogen—salvinorin A G-protein-coupled receptors (GPCRs)1 with a common seven- (SalA)—was also found to be a highly selective k-OR agonist15. -

In silico results of k-Opioid receptor antagonists as ligands for the second bromodomain of the Pleckstrin Homology Domain Interacting Protein Lemmer R. P. EL ASSAL ([email protected]) 25/08/2018 Abstract Pleckstrin Homology Domain Interacting Protein (PHIP) is a member of the BRWD1-3 Family (Bromodomain and WD repeat-containing proteins). PHIP (BRWD2, WDR11) contains a WD40 repeat (methyl-lysine binder) and 2 bromodomains (acetyl-lysine binder). It was discovered through interactions with the pleckstrin homology domain of Insulin Receptor Signalling (IRS) proteins and has been shown to mediate transcriptional responses in pancreatic islet cells and postnatal growth. An initial hit for the second bromodomain of PHIP (PHIP(2)) was discovered in 2012, with consecutive research yielding a candidate with a binding anity of 68mM. PHIP(2) is an atypical category III bromodomain with a threonine (THR1396) where an asparagine residue would usually be. In the standard case, this pocket holds four water molecules, but in the case of PHIP(2), there is room for one extra water molecule - also known as PHIP water, able to mediate interaction between THR1396 and the typical water network at the back of the binding pocket. We present rst ever results of two k-Opioid receptor (KOR) antagonists with distinct pharmacophores having an estimated binding anity in the nM to mM range, as well as higher binding anities for every currently discovered PHIP(2) ligand towards KOR. -

Long-Acting Κ Opioid Antagonists Nor-BNI, GNTI and Jdtic
Munro et al. BMC Pharmacology 2012, 12:5 http://www.biomedcentral.com/1471-2210/12/5 RESEARCH ARTICLE Open Access Long-acting κ opioid antagonists nor-BNI, GNTI and JDTic: pharmacokinetics in mice and lipophilicity Thomas A Munro1*, Loren M Berry2, Ashlee Van’t Veer1, Cécile Béguin1, F Ivy Carroll3, Zhiyang Zhao2, William A Carlezon Jr1 and Bruce M Cohen1 Abstract Background: Nor-BNI, GNTI and JDTic induce κ opioid antagonism that is delayed by hours and can persist for months. Other effects are transient. It has been proposed that these drugs may be slowly absorbed or distributed, and may dissolve in cell membranes, thus slowing elimination and prolonging their effects. Recent evidence suggests, instead, that they induce prolonged desensitization of the κ opioid receptor. Methods: To evaluate these hypotheses, we measured relevant physicochemical properties of nor-BNI, GNTI and JDTic, and the timecourse of brain and plasma concentrations in mice after intraperitoneal administration (using LC- MS-MS). Results: In each case, plasma levels were maximal within 30 min and declined by >80% within four hours, correlating well with previously reported transient effects. A strong negative correlation was observed between plasma levels and the delayed, prolonged timecourse of κ antagonism. Brain levels of nor-BNI and JDTic peaked within 30 min, but while nor-BNI was largely eliminated within hours, JDTic declined gradually over a week. Brain uptake of GNTI was too low to measure accurately, and higher doses proved lethal. None of the drugs were highly lipophilic, showing high water solubility (> 45 mM) and low distribution into octanol (log D7.4 < 2).
