Reactivity of Nucleosides with a Hydroxyl Radical in Non‐aqueous Medium

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).
