Tynorphin is a synthetic opioid peptide which is a potent and competitive inhibitor of the enkephalinase class of enzymes which break down the endogenous enkephalin peptides.[1] It specifically inactivates dipeptidyl aminopeptidase III (DPP3) with very high efficacy, but also inhibits neutral endopeptidase (NEP), aminopeptidase N (APN), and angiotensin-converting enzyme (ACE) to a lesser extent.[1] It has a pentapeptide structure with the amino acid sequence Val-Val-Tyr-Pro-Trp.
Tynorphin was discovered in an attempt to develop an enkephalinase inhibitor of greater potency than spinorphin.[1]
