C-3'-Acyl-3'-xylothymidine-containing oligonucleotides have been designed and synthesized for their use as radical precursors in the study of oxidative DNA damage initiated by a C-3'-radical. These oligomers were efficiently obtained using automated DNA synthesis techniques based on H-phosphonate chemistry. CD spectra and melting curves of the synthesized(More)
