  • Behavioral Evidence for A-Opioid and 5-HT 2A Receptor Interactions
    European Journal of Pharmacology 474 (2003) 77–83 www.elsevier.com/locate/ejphar Behavioral evidence for A-opioid and 5-HT2A receptor interactions Gerard J. Marek* Department of Psychiatry, Yale School of Medicine, New Haven, CT 06508, USA Received 13 February 2003; received in revised form 3 June 2003; accepted 11 June 2003 Abstract Electrophysiological studies have demonstrated a physiological interaction between 5-HT2A and A-opioid receptors in the medial prefrontal cortex. Furthermore, behavioral studies have found that phenethylamine hallucinogens induce head shakes when directly administered into the medial prefrontal cortex. The receptor(s) by which morphine suppresses head shakes induced by serotonin agonists have not been characterized. We administered A-opioid receptor agonists and antagonists to adult male Sprague–Dawley rats prior to treatment with the phenethylamine hallucinogen 1-(2,5-dimethoxy-4-iodophenyl)-2-aminopropane (DOI), which is known to induce head shakes via 5-HT2A receptors. The suppressant action of the moderately selective A-opioid receptor agonist, buprenorphine (ID50f0.005 mg/ kg, i.p.; a A-opioid receptor partial agonist and n-opioid receptor antagonist) was blocked by naloxone and pretreatment with the irreversible A-opioid receptor antagonist clocinnamox. Another A-opioid receptor agonist fentanyl also suppressed DOI-induced head shakes. In contrast, a y-opioid receptor agonist was without effect on DOI-induced head shakes. Thus, activation of A-opioid receptors can suppress head shakes induced by hallucinogenic drugs. D 2003 Elsevier B.V. All rights reserved.

Dickenson Department of Pharmacology, University College London, London WC1E 6BT, United Kingdom Electronic mail: anthony.dickenson6ucl.ac.uk Abstract: The spinal mechanisms of action of opioids under normal conditions are reasonably well understood. The spinal effects of opioids can be enhanced or reduced depending on pathology and activity in other segmental and nonsegmental pathways. This plasticity will be considered in relation to the control of different pain states using opioids. The complex and contradictory findings on the supraspinal actions of opioids are explicable in terms of heterogeneous descending pathways to different spinal targets using multiple transmitters and receptors ± therefore opioids can both increase and decrease activity in descending pathways.

  • Targeting Nitric Oxide and NMDA Receptor-Associated Pathways in Treatment of High Grade Glial Tumors
    Nitric Oxide 79 (2018) 68–83 Contents lists available at ScienceDirect Nitric Oxide journal homepage: www.elsevier.com/locate/yniox Targeting nitric oxide and NMDA receptor-associated pathways in treatment of high grade glial tumors. Hypotheses for nitro-memantine and nitrones T ∗ Meric A. Altinoz , İlhan Elmaci Neuroacademy Group, Department of Neurosurgery, Memorial Hospital, Istanbul, Turkey ARTICLE INFO ABSTRACT Keywords: Glioblastoma multiforme (GBM) is a devastating brain cancer with no curative treatment. Targeting Nitric Oxide Nitric oxide (NO) and glutamatergic pathways may help as adjunctive treatments in GBM. NO at low doses promotes tu- Nitrone morigenesis, while at higher levels (above 300 nM) triggers apoptosis. Gliomas actively secrete high amounts of Nitro-memantine glutamate which activates EGR signaling and mediates degradation of peritumoral tissues via excitotoxic injury. Glial tumor Memantine inhibits NMDA-subtype of glutamate receptors (NMDARs) and induces autophagic death of glioma Glioblastoma cells in vitro and blocks glioma growth in vivo. Nitro-memantines may exert further benefits by limiting NMDAR signaling and by delivery of NO to the areas of excessive NMDAR activity leading NO-accumulation at tumor- icidal levels within gliomas. Due to the duality of NO in tumorigenesis, agents which attenuate NO levels may also act beneficial in treatment of GBM. Nitrone compounds including N-tert-Butyl-α-phenylnitrone (PBN) and its disulfonyl-phenyl derivative, OKN-007 suppress free radical formation in experimental cerebral ischemia. OKN-007 failed to show clinical efficacy in stroke, but trials demonstrated its high biosafety in humans including elderly subjects. PBN inhibits the signaling pathways of NF-κB, inducible nitric oxide synthase (iNOS) and cy- clooxygenase (COX).
