Abstract

We have already demonstrated that the oligonucleotides DNA (ODNs) bearing a 2-amino-6-vinylpurine derivative (1) exhibited efficient interstrand cross-linking to cytidine selectively. In this study, a new reactive nucleoside analogue, 2-amino-6-(1-ethylsulfoxy)vinylpurine derivative (7), was designed based on a computational method to achieve high and selective alkylation with cytidine under neutral conditions. It has been demonstrated that the ODN (13) bearing 2-amino-6-(1-ethylsulfoxy)vinylpurine achieved highly selective and efficient cross-linking to cytidine under neutral conditions.
