| 2] readily forms free radicals, such as superoxide and reactive semiquinone intermediates, via metabolic redox reactions. Since the report by Iyer and Szybalski (1964), the requirement for redox biotransformation of mitomycin C (MMC) has been well recognized in pharmacology, because MMC must be activated by a series of redox reactions leading to semiquinone derivatives coupled with ROS formation (Dusre et al. Using cells transfected with plasmids that express elevated levels of selective enzymes individually or in combination, Joseph and Jaiswal (1994) demonstrated that semiquinone, a metabolite of BaP generated after CYP1A1 and NADPH P-450 reductase activation, resulted in distinct BaP-DNA adducts. |
