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.

TAN-67
0 ImagesCat. No.: HY-101317ACAS No.: 148545-09-9Synonyms: SB-205607TAN-67 (SB-205607) is a non-peptidic delta-opioid receptor agonist that exhibits significant antinociceptive activity in both diabetic and non-diabetic mice. TAN-67 demonstrates a marked and dose-dependent reduction in acetic acid-induced abdominal constrictions, with a notably stronger effect in diabetic mice compared to their non-diabetic counterparts. TAN-67's antinociceptive properties are primarily mediated through the activation of delta 1-opioid receptors, as indicated by the pronounced antagonism observed upon administration of a selective delta 1-opioid receptor antagonist.

CJ-15208
0 ImagesCat. No.: HY-117881CAS No.: 210236-47-8CJ-15208 is a potent and selective κ-opioid receptor antagonist with significant opioid activity. CJ-15208 exhibited strong analgesic effects in the warm water tail withdrawal test in mice and was mediated through multiple opioid receptors. The stereoisomers of CJ-15208 exhibited different opioid activity characteristics, for example, one stereoisomer exhibited κ-opioid receptor antagonism, while the other exhibited δ-opioid receptor antagonism. All stereoisomers of CJ-15208 had no significant effects on respiration. The stereoisomers of CJ-15208 did not lead to the development of drug tolerance, which makes it potential in the further development of safe opioid analgesics.
