    Genotoxicity Revaluation of Three Commercial Nitroheterocyclic Drugs: Nifurtimox, Benznidazole, and Metronidazole by Annamaria Buschini, Lisa Ferrarini, Susanna Franzoni, Serena Galati, Mirca Lazzaretti, Francesca Mussi, Cristina Northfleet de Albuquerque, Tânia Maria Araújo Domingues Zucchi, Paola Poli

    Published 2009-01-01
    “…The compounds are more active for base-pair substitution than frameshift induction in Salmonella; NFX and BNZ are more mutagenic than MTZ; they are widely dependent from nitroreduction whereas microsomal fraction S9 weakly affects the mutagenic potential. Comet assay detects BNZ- and NFX-induced DNA damage at doses in the range of therapeutically treated patient plasma concentration; BNZ seems to mainly act through ROS generation whereas a dose-dependent mechanism of DNA damaging is suggested for NFX. …”
