Indole Alkaloids as Biased Opioid Receptor Modulators
PharmaceuticalsBackground: Opioid receptors are a commonly used target for treatment of pain conditions. Most opioids used in therapy are linked to adverse effects such as tolerance, dependence, and respiratory depression.

Scalable Production of Highly-Sensitive Nanosensors Based on Graphene Functionalized with a Designed G Protein-Coupled Receptor [PDF]
, 2014 We have developed a novel, all-electronic biosensor for opioids that consists of an engineered mu opioid receptor protein, with high binding affinity for opioids, chemically bonded to a graphene field-effect transistor to read out ligand binding.

Boesenbergia rotunda Ethanolic Extract Inhibits Compound Action Potentials via Opioid Receptors
Life Sciences, Medicine and Biomedicine, 2018 Boesenbergia rotunda, traditionally used to relieve stomach, abdomen, joint, muscle, and rheumatic pain was also reported for its antinociceptive effect on a mouse model. However, the possible pain relief effect of Boesenbergia rotunda ethanolic extract (

Nociceptin attenuates the escalation of oxycodone self-administration by normalizing CeA-GABA transmission in highly addicted rats. [PDF]
, 2020 Approximately 25% of patients who are prescribed opioids for chronic pain misuse them, and 5 to 10% develop an opioid use disorder. Although the neurobiological target of opioids is well known, the molecular mechanisms that are responsible for the ...

Placebo Effects Mediated by Endogenous Opioid Activity on μ-Opioid Receptors
Journal of Neuroscience, 2005 Reductions in pain ratings when administered a placebo with expected analgesic properties have been described and hypothesized to be mediated by the pain-suppressive endogenous opioid system.

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.

Threonine 180 Is Required for G-protein-coupled Receptor Kinase 3- and β-Arrestin 2-mediated Desensitization of the µ-Opioid Receptor in Xenopus Oocytes [PDF]
, 2001 To determine the sites in the µ-opioid receptor (MOR) critical for agonist-dependent desensitization, we constructed and coexpressed MORs lacking potential phosphorylation sites along with G-protein activated inwardly rectifying potassium channels ...
