The opioid receptor: emergence through millennia of pharmaceutical sciences
Frontiers in Pain Research, 2023 Throughout history humanity has searched for an optimal approach to the use of opioids that maximizes analgesia while minimizing side effects. This review reflects upon the conceptualization of the opioid receptor and the critical role that the ...

Receptors for morphine and opioids
General Pharmacology: The Vascular System, 1976 Two points concerning enzymatic systems acting on disposal of morphine are discussed, namely the multiplicity of glucuronyltransferase and the effect of nalorphine on N-demethylation of morphine. Evidences of the presence of at least two different glucuronyltransferases in microsomes of rat liver, kidney and intestine are presented. These evidences are

Molecular and cellular mechanisms of the age-dependency of opioid analgesia and tolerance
Molecular Pain, 2012 The age-dependency of opioid analgesia and tolerance has been noticed in both clinical observation and laboratory studies. Evidence shows that many molecular and cellular events that play essential roles in opioid analgesia and tolerance are actually age-

The role of dimerisation in the cellular trafficking of G-protein-coupled receptors [PDF]
, 2010 The concept that G-protein-coupled receptors can exist as homomeric and/or heteromeric complexes is now well established. Despite this, how dynamic such interactions are and if this may be modulated during receptor trafficking remain topics of debate ...

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.

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.

Molecules, 2021 Activated opioid receptors transmit internal signals through two major pathways: the G-protein-mediated pathway, which exerts analgesia, and the β-arrestin-mediated pathway, which leads to unfavorable side effects. Hence, G-protein-biased opioid agonists

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.

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
