Goshajinkigan reduces bortezomib-induced mechanical allodynia in rats: Possible involvement of kappa opioid receptor

open access: yesJournal of Pharmacological Sciences, 2015
In the present study, we investigated the effect of a Kampo medicine Goshajinkigan (GJG) on the bortezomib-induced mechanical allodynia in von Frey test in rats. The single administration of tramadol (10 mg/kg), GJG (1.0 g/kg) and its component processed

Neurons derived from human-induced pluripotent stem cells express mu and kappa opioid receptors

open access: yesNeural Regeneration Research, 2021
Neuroprotection studies have shown that induced pluripotent stem (iPS) cells have the possibility to transform neuroprotection research. In the present study, iPS cells were generated from human renal epithelial cells and were then differentiated into ...

Beyond Nature's Blueprint: Macrocyclic Peptides Containing Unnatural Amino Acids in Therapeutic Development

open access: yesAngewandte Chemie, EarlyView.
Strategic incorporation of unnatural amino acids transforms macrocyclic peptides into drug‐like molecules capable of engaging challenging targets. These building blocks enhance stability, permeability, and bioavailability, accelerating the development of next‐generation peptide therapeutics.

Opioids and opioid receptors; understanding pharmacological mechanisms as a key to therapeutic advances and mitigation of the misuse crisis

open access: yesBJA Open, 2023
Opioids are a mainstay in acute pain management and produce their effects and side effects (e.g., tolerance, opioid-use disorder and immune suppression) by interaction with opioid receptors.

Antinociceptive potency of a fluorinated cyclopeptide Dmt-c[D-Lys-Phe-p-CF3-Phe-Asp]NH2

open access: yesJournal of Enzyme Inhibition and Medicinal Chemistry, 2018
Opioid peptides and opiate drugs such as morphine, mediate their analgesic effects, but also undesired side effects, mostly through activation of the mu opioid receptor.

Role of Opioid Ligands in the Irritable Bowel Syndrome

open access: yesCanadian Journal of Gastroenterology, 1999
Endogenous opioid peptides – enkephalins, beta-endorphin and dynorphins – are located in specific sites of the brain, the spinal cord, the autonomic ganglia and the enteric nervous system.
