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). ; Rodríguez Muñiz, GM.; Marín García, ML.; Miranda Alonso, MÁ.; Lhiaubet, VL. (2012).
