Insights

Kappa opioid receptor (KOR) agonists show neuroprotective effects in cerebral ischemia reperfusion injury. Salvinorin A, a selective KOR agonist, presents potential as a novel treatment for brain injury.

Area of Science:

  • Neuroscience
  • Pharmacology

Background:

  • Kappa opioid receptor (KOR) is implicated in cerebral ischemia reperfusion injury.
  • KOR agonists traditionally exhibit anti-nociceptive and other effects, but emerging evidence highlights neuroprotection.

Purpose of the Study:

  • To review the properties of KOR agonists.
  • To elucidate the role of KOR agonists in global and focal cerebral ischemia.
  • To assess the neuroprotective potential of KOR agonists.

Main Methods:

  • Review of preclinical research on KOR agonists and cerebral ischemia.
  • Analysis of the role of salvinorin A as a selective KOR agonist.

Main Results:

  • Preclinical data suggest KOR agonists possess neuroprotective properties.
  • Salvinorin A, a selective KOR agonist, serves as a valuable tool for studying KOR's role in brain injury.

Conclusions:

  • KOR agonists demonstrate potential as neuroprotective agents for cerebral ischemia.
  • Salvinorin A's unique profile and human usage history suggest its candidacy for treating brain injury.

Opioid Receptors: Overview01:22

Opioid Receptors: Overview

Opioid receptors, including the mu (μ, MOR), delta (δ, DOR), and kappa (κ, KOR) types, belong to the rhodopsin family of G protein-coupled receptors. These receptors are located throughout the central and peripheral nervous systems and in non-neuronal tissues such as macrophages and astrocytes. Opioid receptor ligands can be categorized into agonists or antagonists. Highly selective agonists include [d-Ala2, MePhe4, Gly(ol)5]-enkephalin or DAMGO for MOR, [D-Pen2,...

Analgesia and Pain Management

Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...

Ischemic Stroke ll: Pathophysiology

An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...

Ischemic Stroke l: Introduction01:15

Ischemic Stroke l: Introduction

Ischemic stroke is an acute cerebrovascular condition in which blood flow to a brain region is suddenly interrupted, leading to tissue infarction. Neurons depend on continuous oxygen and glucose supply, so even brief reductions in perfusion cause energy failure, ionic imbalance, and irreversible injury. Ischemic strokes are classified into thrombotic and embolic types based on their underlying mechanisms.Thrombotic MechanismsThrombotic stroke develops when a clot forms within a cerebral artery.

Opioid Analgesics: Morphine and Other Natural Cogeners

Opioids are a class of drugs that mimic endogenous opioid peptides and act on opioid receptors, and help in pain relief. These compounds are classified as natural, synthetic, or semi-synthetic. Natural opioids, like morphine, codeine, and thebaine, are derived from the opium poppy plant (Papaver somniferum or Papaver album) and are termed opiates. Synthetic opioids are artificial, while semi-synthetic opioids combine natural and synthetic compounds. Morphine, a prototypical opioid, possesses a...
