title: A ribonucleoside with pyrimido[4,5-d]pyrimidine-2,4,5,7-(1H,3H,6H,8H)-tetraone as a nucleobase, which universally binds to natural nucleosides.
abstract: A ribonucleoside with pyrimido[4,5-d]pyrimidine-2,4,5,7-(1H,3H,6H,8H)-tetraone, which is expected to serve as a universal base, was synthesized and binding affinity of this artificial nucleoside to natural nucleosides was investigated by UV analysis. As the result, it was revealed that the artificial derivative universally forms a base pair with four kinds of natural deoxyribonucleosides.
