Dynorphin A acetate is a heptadecapeptide derived from the cleavage of prodynorphin and found widely distributed in the central nervous system. It acts as an endogenous kappa receptor agonist with nanomolar binding affinity. It also activates the human novel opioid receptor-like receptor of ORL1. It is resistant to enzymatic degradation and may have antinociceptive functions.
