Usefulness for the combination of G protein- and β-arrestin-biased ligands of μ-opioid receptors: Prevention of antinociceptive tolerance

Molecular Pain, 2017
Background µ-Opioid receptor internalization is considered to be critically linked to antinociceptive tolerance. Although µ-opioid receptor agonists have been administered simultaneously with other drugs to control pain, little information is available ...

Small-molecule nociceptin receptor agonist ameliorates mast cell activation and pain in sickle mice

Haematologica, 2015
Treatment of pain with morphine and its congeners in sickle cell anemia is suboptimal, warranting the need for analgesics devoid of side effects, addiction and tolerance liability. Small-molecule nociceptin opioid receptor ligands show analgesic efficacy

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

Opioid mediated activity and expression of mu and delta opioid receptors in isolated human term non-laboring myometrium

, 2013
The existence of opioid receptors in mammalian myometrial tissue is now widely accepted. Previously enkephalin degrading enzymes have been shown to be elevated in pregnant rat uterus and a met-enkephalin analogue has been shown to alter spontaneous ...

Delta-opioid receptor–mediated neural protection and regeneration

Neural Regeneration Research
The delta-opioid receptor was previously viewed as a mediator in pain regulation. Recent data shed light on its specific role in neural protection and regeneration.

Characterization of methadone as a β-arrestin-biased μ-opioid receptor agonist

Molecular Pain, 2016
Background Methadone is a unique µ-opioid receptor agonist. Although several researchers have insisted that the pharmacological effects of methadone are mediated through the blockade of NMDA receptor, the underlying mechanism by which methadone exerts ...

Opioid and cannabinoid receptors

Current Opinion in Neurobiology, 1994
Opioids and cannabinoids are two major classes of drugs with important clinical uses as well as significant side effects. Recently, the three major subtypes of opioid receptors, delta, kappa and mu, have been cloned. Both the endogenous cannabinoids and their receptors have also recently been cloned.
