Abstract
DNA damage: The reactivity of HO(.) with silylated 2'-deoxyribonucleosides was investigated in acetonitrile by means of a time-resolved technique. The obtained rate constants were in general slightly lower than those reported for the natural nucleosides in water. Analysis of the reaction mixture by UPLC-MS revealed that HO(.) attack occurred at the nucleobase (see scheme).
