N(2)-phenyldeoxyguanosine: modulation of the chemical properties of deoxyguanosine toward one-electron oxidation in DNA.

Abstract

We have shown here that (1) substitution of an exocyclic amino group of dG is effective in modulating the chemical properties of dG toward one-electron oxidation and (2) decomposition of the guanine radical cation was effectively suppressed near dPhG. These results indicate that dPhG is a prototype of nucleosides functioning as an intrinsic antioxidant of duplex DNA toward one-electron oxidation.
