Summary

 Dynorphin was first isolated from porcine pituitary and partially sequenced in 1979. Although the determined N-terminal tridecapeptide (dynorphin 1-13) contained Leu-enkephalin as its N-terminus, its opioid activity estimated by electrically stimulated guinea-pig ileum preparations was far more potent than that of Leu-enkephalin and equipotent to that of original dynorphin, which is the most potent opioid peptide so far isolated.

 Being used dynorphin 1-13 for the characterization of dynorphin, there have been accumulated several evidences that dynorphin is an endogenous ligand for kappa receptors.
