Kinetics and mechanism for reduction of Pt(IV) anticancer model compounds by Se-methyl L-selenocysteine. Comparison with L-selenomethionine.
Se-methyl L-selenocysteine (MeSeCys) is one of the major organic selenium compounds acquired from the diet by human beings. It has been shown to have anticancer activity and cancer prevention functions. However, its antioxidant activity, largely related to its biological function, has not been well characterized so far. We here report a stopped-flow kinetic study of the reduction of the Pt(IV) antSe-methyl L-selenocysteine (MeSeCys) is one of the major organic selenium compounds acquired from the diet by human beings.
