Batch specific analytical results are provided on each certificate of analysis. Laboratory Procedures Spinorphin is supplied as a crystalline solid. A stock solution may be made by dissolving the spinorphin in the solvent of choice, which should be purged with an inert gas. Spinorphin is soluble in organic solvents such as DMSO and dimethyl formamide. The solubility of spinorphin in these solvents is approximately 30 mg/ml. Description Spinorphin is a heptapeptide inhibitor of the enkephalin-degrading enzymes aminopeptidase, dipeptidyl aminopeptidase, angiotensin-converting enzyme (ACE), and enkephalinase (IC50s = 3.3, 1.4, 2.4, and 10 µg/ml, respectively, for monkey brain enzymes).1 It is selective for these enzymes over human serum aminopeptidase A (IC50 = >100 µg/ml), as well as porcine kidney aminopeptidase B, aminopeptidase M, dipeptidyl peptidase 1 (DPP-1), DPP-2, DPP-3, and DPP-4 (IC50s = >55 µg/ml for all). Spinorphin inhibits chemotaxis, production of reactive oxygen species (ROS), and exocytosis of glucuronidase and collagenase in polymorphonuclear neutrophils (PMNs). It potentiates enkephalin-induced action potentials in rat hippocampal slices.

Celik Department of Experimental Anesthesiology, Charité – Universitätsmedizin Berlin, Corporate Member of Freie Universität Berlin, Humboldt-Universität zu Berlin, Berlin Institute of Health, Berlin, Germany Opioid receptors comprise µ (MOP), δ (DOP), κ (KOP), and nociceptin/orphanin FQ (NOP) receptors. Opioids are agonists of MOP, DOP, and KOP receptors, whereas nociceptin/orphanin FQ (N/OFQ) is an agonist of NOP receptors. Activation of all four opioid receptors in neurons can induce analgesia in animal models, but the most clinically relevant are MOP receptor agonists (e.g., morphine, fentanyl). Opioids can also affect the function of immune cells, and their actions in relation to immunosuppression and infections have been widely discussed. Here, we analyze the expression and the role of opioid receptors in peripheral immune cells and glia in the modulation of pain.

    U.S. DEPARTMENT OF JUSTICE DRUG ENFORCEMENT ADMINISTRATION WWW.DEA.GOV 9, 2014 on September archived 13-10048 No. v. Stewart, in U.S. cited Drugs of2011 Abuse EDITION A DEA RESOURCE GUIDE V. Narcotics WHAT ARE NARCOTICS? Also known as “opioids,” the term "narcotic" comes from the Greek word for “stupor” and originally referred to a variety of substances that dulled the senses and relieved pain. Though some people still refer to all drugs as “narcot- ics,” today “narcotic” refers to opium, opium derivatives, and their semi-synthetic substitutes. A more current term for these drugs, with less uncertainty regarding its meaning, is “opioid.” Examples include the illicit drug heroin and pharmaceutical drugs like OxyContin®, Vicodin®, codeine, morphine, methadone and fentanyl. WHAT IS THEIR ORIGIN? The poppy papaver somniferum is the source for all natural opioids, whereas synthetic opioids are made entirely in a lab and include meperidine, fentanyl, and methadone. Semi-synthetic opioids are synthesized from naturally occurring opium products, such as morphine and codeine, and include heroin, oxycodone, hydrocodone, and hydromorphone. Teens can obtain narcotics from friends, family members, medicine cabinets, pharmacies, nursing 2014 homes, hospitals, hospices, doctors, and the Internet. 9, on September archived 13-10048 No. v. Stewart, in U.S. cited What are common street names?

    Extensions des propriétés des inhibiteurs mixtes des enképhalinases aux douleurs de la sphère cranio-faciale. Nouvelles applications à la migraine et aux douleurs de la cornée. Bernard P. Roques Professeur Emérite, Université Paris Descartes Unité 1267 Inserm, 4 avenue de l’Observatoire, 75006 Paris. ATHS Biarritz, 1-4 Octobre 2019 CONFIDENTIAL 1 Endorphins and their receptors. Endomorphin-1 Tyr – Pro – Trp – Phe – NH2 Endomorphin-2 Tyr – Pro – Phe – Phe – NH2 2 2 Drug Discovery : designing the ideal opioid (From B.L. Kieffer, Nature (2016), 537, 170-171) 3 Three levels of pain control by endogenous opioid system (EOS) EOS EOS Attacking pain at EOS its source Relieving or reducing pain at its source More than 50% of MO effects are attributable to peripheral neurons (nociceptors) Roques, B.P., Fournié-Zaluski, M.C. and Wurm, M., Nature Reviews Drug Discovery, 2012 4 DENKIs: mechanism of action The endogenous opioid system (EOS) is present at all levels of physiological-nociceptive control i.e. periphery, spinal cord and brain Elements of the EOS are opioid receptors, enkephalins and their inactivating enzymes Dual Inhibitors of ENKephalinases (DENKIs) potentiate physiological functions of DENKI enkephalins (e.g. pain control) only on those pathways where they are tonically released Enkephalinases APN NEP No adverse effects Enkephalins Y G G F M(L) (endogenous) Opioid receptors Morphine indiscriminatingly overstimulates all opioid receptors including those not involved in (Morphine) pain control (exogenous) Adverse effects 5 Synergistic combinations of the dual enkephalinase inhibitor PL265 given orally with various analgesic compounds acting on different targets in a murine model of bone cancer-induced pain.
