Mitragynine (MG) is an indole alkaloid from kratom plant that binds opioid receptors and as such presents a scaffold for the development of atypical opioid receptor modulators.

Pain is one of the most common and incapacitating symptoms experienced by patients with advanced cancer. Methadone is a potent opioid with strong affinity for the µ opioid receptor. In addition to being a potent µ opioid receptor ligand, methadone blocks

Effects of Loperamide on Mechanical Allodynia Induced by Herpes Simplex Virus Type-1 in Mice
In the present study, we investigated whether the peripherally acting µ-opioid receptor agonist loperamide would inhibit allodynia in the non-inflamed dermatome of mice with herpetic pain.

Opioids and opioid receptors orchestrate wound repair [PDF]
We have previously shown that topical opioids including morphine and its congeners promote healing of full thickness ischemic wounds in rats. We examined the contribution of mu opioid receptor (MOPr)-mediated healing of full thickness ischemic wounds using MOPr and delta or kappa opioid receptor knockout (KO) mice. Wound closure in the early (day 5) as

µ-Opioid receptor antagonism facilitates the anxiolytic-like effect of oxytocin in mice
Mood and anxiety disorders are leading causes of disability worldwide and are major contributors to the global burden of diseases. Neuropeptides, such as oxytocin and opioid peptides, are important for emotion regulation.

Better agonist for the opioid receptors [PDF]
This commentary highlights the recent work published in journal Nature on the structural based discovery of novel analgesic compounds for opioid receptors with minimal effects. Manglik et al. selectively targeted the Gi based μOR pathway instead of the β-arrestin pathway of the opioids. The computational screening of millions of compounds showed a list

Recent experimental and clinical research has demonstrated that opioids can produce potent and receptor-specific analgesic effects outside the central nervous system. Opioid receptors are localized on peripheral terminals of sensory nerves and their endogenous ligands, opioid peptides, have been discovered in immune cells within inflamed tissue.

Molecular Aspects of Opioid Receptors and Opioid Receptor Painkillers
The unpleasant sensation of pain is experienced by all human beings at a given point in life. When pain gets severe and/or chronic it requires medical treatment. For over a thousand years, opioid agonists have been employed therapeutically to treat pain, with the first reports of such use involving the alkaloid morphine dated to the second century B.C.(
