Alteration of cross-linking selectivity with the 2′-OMe analogue of 2-amino-6-vinylpurine and evaluation of antisense effects
摘要:
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'-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'-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.
