(2S)-2-{[(2S,3R)-2-{[(2S)-2-({[(2S)-1-[(2S)-2-{[(2S)-2-{[(2S)-2-amino-1-hydroxy-3-methylbutylidene]amino}-1-hydroxy-3-methylbutylidene]amino}-3-(4-hydroxyphenyl)propanoyl]pyrrolidin-2-yl](hydroxy)methylidene}amino)-1-hydroxy-3-(1H-indol-3-yl)propylidene]amino}-1,3-dihydroxybutylidene]amino}pentanedioic acid
Valorphin, also known as VV-hemorphin-5, is a naturally occurring, endogenous opioid heptapeptide of the hemorphin family with the amino acid sequence Val-Val-Tyr-Pro-Trp-Thr-Gln. It is produced in the body via proteolyic cleavage of residues 33-39 of the β-chain of hemoglobin. Valorphin binds preferentially to the μ-opioid receptor and produces effects such as analgesia and self-administration in animals. Interestingly, it also possesses cytotoxic and antiproliferative properties against tumor cells.
