One-electron oxidation of a pyrenyl photosensitizer covalently attached to DNA and competition between its further oxidation and DNA hole injection

The photosensitized hole injection and guanine base damage phenomena have been investigated in the DNA sequence, 5′-d(CATG(1)(Py)CG(2)TCCTAC) with a site-specifically positioned pyrene-like (Py) benzo[a]pyrene 7,8-diol 9,10-epoxide – derived N(2)-guanine adduct (G(1)(Py)). Generation of the Py radic...
