Dynorphin A is a form of dynorphin and an endogenous opioid peptide with the amino acid sequence: Tyr-Gly-Gly-Phe-Leu-Arg-Arg-Ile-Arg-Pro-Lys-Leu-Lys.

Dynorphin A1–8 is a truncated form of dynorphin A with the amino acid sequence: Tyr-Gly-Gly-Phe-Leu-Arg-Arg-Ile.[2][3] Dynorphin A1–8 is an agonist at the mu-, kappa-, and delta-opioid receptors;[3] it has the highest binding affinity for the kappa-opioid receptor.[3]
