Docking Studies of Kappa Opioid Receptor Agonists

چکیده
The purpose of the study was to compare the binding energy of pharmacophores of different classes targeting to kappa opioid receptor (KOR) with ketazocine and pentazocine which are having good activity on the KOR. The 3D structure of KOR receptor was built by Homology modeling; pharmacophores were characterized by using Ligand scout. Docking studies for the KOR agonists were performed in Autodock4.0. It was observed that 2-(3,4-Dichloro-2methylphenyl)-N-methyl-N-[(5R,7S,8S)-7-(pyrrolidin-1-yl)-1-oxaspiro[4.5]dec-8-yl]acetamide and 6-(2-{2-(Dimethylamino) methyl]piperidin-1-yl}-2-oxoethyl)-3,4-dihydronaphthalen-1(2H)-one compounds may exhibit better activity than ketazocine. This study states the importance of pharmacophoric groups and their use to enhance drug discovery process prior synthesis.

Molecular docking study of Papaver alkaloids to some alkaloid receptors
Background and objectives: More than 40 different alkaloids have been obtained from opium the most important of which are morphine, codeine, papaverine, noscapine and tabaine. Opioid alkaloids produce analgesia by affecting areas of the brain that have peptides with pharmacological pseudo-opioid properties. These alkaloids show important effects on some intracellular peptides l...

متن کاملSystemic kappa opioid receptor agonists in the treatment of chronic pruritus: a literature review.
Chronic pruritus is frequently refractory to currently available treatments. Studies suggest that pruritus may arise from an imbalance of the mu- and kappa-opioid receptor system activity in either the skin or the central nervous system. Stimulation of kappa-opioid receptors by their agonists inhibits pruritus in both animals and humans. The antipruritic effect of kappa-opioid receptors agonist...
متن کاملSynthetic and Receptor Signaling Explorations of the Mitragyna Alkaloids: Mitragynine as an Atypical Molecular Framework for Opioid Receptor Modulators.
Mu-opioid receptor agonists represent mainstays of pain management. However, the therapeutic use of these agents is associated with serious side effects, including potentially lethal respiratory depression. Accordingly, there is a longstanding interest in the development of new opioid analgesics with improved therapeutic profiles. The alkaloids of the Southeast Asian plant Mitragyna speciosa, r...
متن کاملDifferentiation of kappa opioid agonist-induced antinociception by naltrexone apparent pA2 analysis in rhesus monkeys.
Naltrexone (NTX) exhibited approximately 3-fold higher affinity for sites labeled by [3H]U69,593 (putative kappa 1-selective ligand) than [3H]bremazocine (non-selective ligand) in the presence of mu and delta receptor blockade in monkey brain membranes. This led us to test an hypothesis that NTX could display in vivo antagonist selectivity for kappa 1-versus non-kappa 1-mediated effects. Six op...
