| Outline of Final Research Achievements |
This research project was carried out for a year in FY2015. In this year we established the efficient synthetic process of poly(ADP-ribose). Because of the short research term, we concentrated to the synthesis of a linear poly(ADP-ribose) and explored the best suited reaction conditions. Based on a phosphoramidite process, one of DNA solid support synthesis, we created a new chemical synthesis of poly(ADP-ribose). Ribosyladenosine was protected with a dimethoxytrityl group for a hydroxy group to be linked with another building block and benzoyl groups for a the other hydroxy groups. In addition, a ribose unit for a starter and a adenosine unit for a capping were also prepared. We obtained a ADP-ribose dimer through a synthetic cycle.
