This dipeptide found in plasma and urine is generated during the catabolism of glutathione. Cysteinylglycine has been suggested to induce oxidative stress and lipid peroxidation, leading to the development of human cancers.
H-Cys-Gly-OH is a cyclic peptide that has potent antitumor activity. It was synthesized from glutathione and cysteine, which are naturally occurring amino acids in the human body. The mechanism of action of H-Cys-Gly-OH is not well understood, but it may be due to its ability to bind to α1-acid glycoprotein and other proteins in the blood. The compound also has a redox potential, fluorescence spectra, and structural analysis that can be used for identification purposes. This molecule is stable at acid pH and is easily soluble in water or organic solvents. H-Cys-Gly-OH can be analyzed by titration calorimetry or cyclic voltammetry methods.
