General information

  • Opioid neuropeptide.
  • Dynorphin A (Dyn A), and dynorphin B (Dyn B) are endogenous opioid peptides that activate the kappa-opioid receptor (KOR). [1]
  • Dynorphin A inhibits NMDA receptors through a pH-dependent mechanism. [2]
  • Antagonist of melanocortin receptors; has non-opioid effects that include inflammation and aggravation of traumatic nerve injury. [3]
