✦ Synopsis
We previously reported that oligodeoxynucleotides containing 2-amino-6-vinylpurine (2-AVP: 1) exhibit efficient selective cross-linking to cytosine. In this study, the 2 0 -OMe nucleoside analogue (2) of 2-AVP was designed in order to increase its affinity to RNA and enhance metabolic stability. It has been demonstrated that 2 0 -OMe oligonucleotides bearing 2 achieve highly selective cross-linking to the thymine base in DNA and show higher antisense effect on luciferase production in cell lysate.
