  • Title: Enzymatic and non-enzymatic formation of free radicals from aflatoxin B1.
    Author: Kodama M, Inoue F, Akao M.
    Journal: Free Radic Res Commun; 1990; 10(3):137-42. PubMed ID: 2168856.
    Abstract:
    Formation of free radicals from aflatoxin B1 was demonstrated in systems of a) NADPH/microsome, b) H2O2/peroxidase, c) UV irradiation, d) silver oxide oxidation and e) alkaline dimethyl sulfoxide. In a) to c), radical spots were detected in thin-layer chromatograms. Among several known metabolites of aflatoxin B1, aflatoxin M1 was active in generation of free radical. These results suggest a possible role of free radical metabolites in the cytotoxicity of this hepatocarcinogen.
