Amidorphin is an endogenous, C-terminally amidated, opioid peptide generated as a cleavage product of proenkephalin A that is widely distributed in the mammalian brain, with particularly high concentrations found in the adrenal medulla, posterior pituitary, and striatum.[1][2] In some brain areas, amidorphin is extensively further reduced into smaller fragments, such as the non-opioid peptide amidorphin-(8-26) which lacks the N-terminal [Met]enkephalin sequence of amidorphin; accordingly, [Met]enkephalin may also be a cleavage product of amidorphin.[3]
