| Research Abstract |
The chemical reactions to DNA are known to induce the mutation in the genetic information and leads to the various diseases, such as cancer. Especially, the electron transfer through duplex DNA can occur under the conditions of oxidative stress, and induce the DNA damage, for example oxidative damage. But it is very difficult to regulate the selectivity of these reactions. In this study, we have developed the new strategy to induce the selective point mutation by regulation of the electron transfer through the DNA. For achievement of our study, there are two key points; one is the producing the effective radical cation by photo-reaction, and second is the reaction to induce the nucleophilic reaction or the oxidative reaction. In this study, we synthesized the oligonucleotides containing anthraquinone as a photosensitizer and 2-amino-6-vinyl derivatives as a reactive moiety. These oligonucleotide provides the possibility to induce the selective reactions to target bases.
