    • Omission of the xanthine oxidase substrate xanthine from the reaction mixture removes the source of reducing equivalents for the reduction of 1 by xanthine oxidase.

    • 11 Poor cleavage by 3 may be due primarily to the fact that the compound is not efficiently reduced by the xanthine-xanthine oxidase enzyme system used in these studies (J S. Daniels, K. S. Gates, unpublished data); however, we suggest that the small amount of observed DNA cleavage by the mono-N-oxide 3 may proceed by a hydroxyl radical-liberating mechanism analogous to pathway a in Scheme 1

    • note
    • Of course, the possibility exists that, when produced in vivo, radical 2 reacts with non-nucleic acid components of the cell and the resulting radicals lead to DNA cleavage.
