Opioid Receptor
Opioid receptors are a group of G protein-coupled receptors with opioids as ligands. The endogenous opioids are dynorphins, enkephalins, endorphins, endomorphins and nociceptin. Opioid receptors are distributed widely in the brain, and are found in the spinal cord and digestive tract. Opioid receptors are molecules, or sites, within the body that are activated by opioid substances. Opioid receptors inhibit the transmission of impulse in excitatory pathways within the human body system. These pathways include the serotonin, catecholamine, and substance P pathways, which are all implicated in pain perception and feelings of well-being. Opioid receptors are further subclassified into mu, delta, and kappa receptors. All the classes, while exhibiting differing modes of action, share some basic similarities. They all are driven by the potassium pump mechanism, which is found on the plasma membrane of the majority of cells.

Gluten Exorphin C
0 ImagesGluten exorphin C is an opioid peptide derived from wheat gluten. Its IC50 values are 40 μM and 13.5 μM for μ opioid and δ opioid activities in the GPI and MVD assays, respectively.
-
AR-M 1000390 hydrochloride
0 ImagesAR-M 1000390 hydrochloride is an exceptionally selective, potent δ opioid receptor agonist with an EC50 of 7.2±0.9 nM for δ agonist potency.
-
Dalargin
0 ImagesDalargin is a potent δ-opioid receptor agonist. Dalargin mitigates Gentamicin (HY-A0276)-induced cell death. Dalargin shows nephroprotective effects on Gentamicin (HY-A0276A)-induced kidney injury. Dalargin shows antiulcer activity.
-
Endomorphin 1 acetate
0 ImagesEndomorphin 1 acetate, a high affinity, highly selective agonist of the μ-opioid receptor (Ki: 1.11 nM), displays reasonable affinities for kappa3 binding sites, with Ki value between 20 and 30 nM. Endomorphin 1 acetate has antinociceptive properties.
-
4-Isopropylbenzyl alcohol
0 Images4-Isopropylbenzyl alcohol (Cuminic alcohol) is an opioid-dependent analgesic. 4-Isopropylbenzyl alcohol activates opioid receptor, regulates the L-Arginine (HY-N0455)/NO/cGMP pathway, and reduces spinal cord TNF-α and IL-1β levels; it binds to BSA (HY-D0842) via static quenching. 4-Isopropylbenzyl alcohol can be used in research related to nociceptive pain, neuropathic pain, bacterial infection and diabetes.
-
H-20
0 ImagesH-20 is a PD-1 agonist peptide. H-20 increases μOR mRNA in DRG neurons and modulates μOR-mediated analgesia. H-20 produces synergistic analgesic effects in inflammatory pain models and can reduce analgesic-induced tolerance, hyperalgesia, constipation, and motor impairment. H-20 can be used in pain-related research.
-
NPFF1-R antagonist 1
0 ImagesNPFF1-R antagonist 1 (compound 8b), a piperidine analogue, is a potent neuropeptide FF (NPFF) receptor antagonist. NPFF1-R antagonist 1 is 15-fold selective for the NPFF1-R subtype, with Ki values of 211 nM and 3270 nM for NPFF1-R and NPFF2-R, respectively.
-
Alvimopan metabolite hydrochloride
0 ImagesAlvimopan metabolite hydrochloride is a peripherally restricted Opioid Receptor antagonist that inhibits the amplitude of electrically evoked contractions and spontaneous mechanical activity in guinea pig ileum.
-
Naltrexone-d4
0 ImagesNaltrexone-d4 is deuterium labeled Naltrexone (HY-76711). Naltrexone is an orally active, long-acting opioid receptor (opioid receptor) antagonist. Naltrexone blocks the euphoric effects of exogenous opioids and reduces alcohol craving by blocking opioid receptors (μ, κ, and δ) as well as opioid growth factor receptors. Low doses of Naltrexone are used to relieve chronic pain, treat inflammatory diseases and inhibit tumor growth, while high doses or continuous administration exert pro-inflammatory or pro-proliferative effects. Naltrexone relieves intractable pruritus caused by psoriasis, atopic dermatitis and other conditions, and its combination with Bupropion (HY-B0403) inhibits food craving, thereby reducing body weight.
