One-electron oxidation of 8-oxodG induced by laser flash photolysis of AAPH in air-equilibrated buffer solutions (pH 7, [O2] = 0.27 mM). Transient absorption spectra were recorded at the indicated delay times after a 355 nm single laser pulse excitation (E = 20 mJ/pulse/cm2) of 20 mM AAPH and 0.03 mM 8-oxodG. The inset shows the kinetic profile of 8-oxodG•+/8-oxodG(-H)• radicals at 325 nm in air-equilibrated (red trace) and argon-purged (blue) solutions.
