Contribution of mu and delta opioid receptors to the pharmacological profile of kappa opioid receptor subtypes [PDF]

European Journal of Pain, 2011
AbstractMolecular cloning has identified three opioid receptors: mu (MOR), delta (DOR) and kappa (KOR). Yet, cloning of these receptor types has offered little clarification to the diverse pharmacological profiles seen within the growing number of novel opioid ligands, which has led to the proposal of multiple subtypes.

Efficacy and safety of a selective partial agonist for nociception/orphanin‐FQ peptide (NOP) receptors in patients with insomnia disorder

British Journal of Clinical Pharmacology, EarlyView.
Aims Insomnia is a common sleep disorder, affecting up to 20% of the world population and adversely impacting productivity, health, and overall well‐being. Although pharmacologic options exist to treat insomnia, the health‐related quality of life for patients who are prescribed hypnotics is no higher than for those who are not, revealing a significant ...

Repeated Administration of Norbinaltorphimine Produces Cumulative Kappa Opioid Receptor Inactivation

Frontiers in Pharmacology, 2019
Kappa receptor activation by dynorphins contributes to the anxiogenic, dysphoric, and cognitive disrupting effects of repeated stress, suggesting that kappa receptor antagonists might have therapeutic utility in the treatment of stress disorders.

Modifying Antibiotic Activity of Synthetic Thiadiazine Analogs Against MDR Bacteria and ADMET Analysis

ChemistryOpen, EarlyView.
The study demonstrated that thidiazine compounds potentiated the action of antibiotics. The compounds associated with norfloxacin against S. aureus showed greater significance in relation to the other medications. The indiscriminate use of antibiotics has led to the selection of resistant bacterial strains, significantly reducing the effectiveness of ...

Role of kappa‐opioid and mu‐opioid receptors in pruritus: Peripheral and central itch circuits

Experimental Dermatology, 2022
Modern genetic approaches in animal models have unveiled novel itch‐specific neural pathways, emboldening a paradigm in which drugs can be developed to selectively and potently target itch in a variety of chronic pruritic conditions.

Comprehensive Insights into Natural Bioactive Compounds: From Chemical Diversity and Mechanisms to Biotechnological Innovations and Applications

ChemistryOpen, EarlyView.
Natural products derived from plants, animals, fungi, bacteria, and minerals contain diverse bioactive classes such as alkaloids, flavonoids, terpenoids, saponins, tannins, and phenolics. These natural products work through different mechanisms, including ROS inhibition, NF‐κB suppression, and cytokine regulation, and exhibit wide applications across ...

The effects of kappa opioid agonist RU-1205 on local field potentials and behavior in the discriminative stimulus paradigm

Фармация и фармакология (Пятигорск)
Kappa opioid receptors play a pivotal role in regulating both physiological and cognitive processes. RU-1205, a benzimidazole derivative acting as a specific kappa opioid receptor agonist, has demonstrated the capacity to modulate neuronal activity ...

Effect of butorphanol in combination with xylazine during castration of calves: A randomised trial under field conditions

Veterinary Record, EarlyView.
Abstract Background In horses, cats and dogs, the opioid butorphanol has been proven effective in management of visceral pain and for peri‐ and postoperative pain relief. The aim of this study was to evaluate physiological responses and indicators of noxious stimuli when adding butorphanol to xylazine for sedation of bull calves during surgical ...

Psychedelic‐assisted treatment for substance use disorder: A narrative systematic review

Addiction, EarlyView.
Abstract Background and aims This is the first systematic review of the extant literature on all major psychedelic‐assisted treatment for alcohol use disorder (AUD), tobacco use disorder (TUD) and other substance use disorders (SUD). We aimed to summarise the evidence for efficacy of psychedelic‐assisted treatment for AUD, TUD, and SUD; to evaluate its

Kappa opioid receptor modulation of endometriosis pain in mice

Neuropharmacology, 2021
The kappa opioid receptor is a constituent of the endogenous opioid analgesia system widely expressed in somatosensory nervous pathways and also in endometrial tissues. This work investigates the possible involvement of kappa opioid receptor on the nociceptive, behavioral and histopathological manifestations of endometriosis in a murine model.
