IUPHAR Review - Bivalent and bifunctional opioid receptor ligands as novel analgesics

Pharmacological Research, 2023
Though efficacious in managing chronic, severe pain, opioid analgesics are accompanied by significant adverse effects including constipation, tolerance, dependence, and respiratory depression.

Inhibition of activity of GABA transporter GAT1 by δ-opioid receptor [PDF]

, 2012
Analgesia is a well-documented effect of acupuncture. A critical role in pain sensation plays the nervous system, including the GABAergic system and opioid receptor (OR) activation.

Targeting peripheral opioid receptors to promote analgesic and anti-inflammatory actions

Frontiers in Pharmacology, 2013
Mechanisms of endogenous pain control are significant. Increasing studies have clearly produced evidence for the clinical usefulness of opioids in peripheral analgesia.

The effects of pioglitazone, a PPARγ receptor agonist, on the abuse liability of oxycodone among nondependent opioid users [PDF]

, 2016
Aims: Activation of PPARγ by pioglitazone (PIO) has shown some efficacy in attenuating addictive-like responses in laboratory animals. The ability of PIO to alter the effects of opioids in humans has not been characterized in a controlled laboratory ...

Delta-opioid receptor endocytosis in spinal cord after dermenkephalin activation

BMC Neuroscience, 2000
Background The delta(δ)-opioid receptors belong to the G protein-coupled receptors and in vitro studies have shown that δ-opioid receptors undergo an internalization process in response to agonist stimulation.

Delta opioid receptors regulate temporoammonic-activated feedforward inhibition to the mouse CA1 hippocampus. [PDF]

PLoS ONE, 2013
The opioid system influences learning and memory processes. However, neural mechanisms underlying the modulation of hippocampal activity by opioid receptors remain largely unknown. Here, we compared how mu and delta receptors operate within the mouse CA1

Solid Tumor Opioid Receptor Expression and Oncologic Outcomes: Analysis of the Cancer Genome Atlas and Genotype Tissue Expression Project

Frontiers in Oncology, 2022
BackgroundOpioid receptors are expressed not only by neural cells in the central nervous system, but also by many solid tumor cancer cells. Whether perioperative opioids given for analgesia after tumor resection surgery might inadvertently activate tumor

Evaluation of the analgesic effect of 4-anilidopiperidine scaffold containing ureas and carbamates [PDF]

, 2016
Fentanyl is a powerful opiate analgesic typically used for the treatment of severe and chronic pain, but its prescription is strongly limited by the well-documented side-effects.

Opioids and opioid receptors; understanding pharmacological mechanisms as a key to therapeutic advances and mitigation of the misuse crisis

BJA Open, 2023
Opioids are a mainstay in acute pain management and produce their effects and side effects (e.g., tolerance, opioid-use disorder and immune suppression) by interaction with opioid receptors.

Butorphanol: Effects of a Prototypical Agonist-Antagonist Analgesic on κ-Opioid Receptors

Journal of Pharmacological Sciences, 2005
The opioid analgesic, butorphanol (17-cyclobutylmethyl-3,14-dihydroxymorphinan) tartrate is a prototypical agonist-antagonist opioid analgesic agent whose potential for abuse has been the cause of litigation in the United States.
