Abstract
The present invention relates to novel unnatural fluorescent nucleic acid bases, that is, a purine base, a 1-deazapurine base, and a 1,7-deazapurine base each having a functional group which consists of two or more heterocyclic moieties linked together, at the 6-position thereof (the 6-position of purine ring). The present invention also relates to a compound containing the unnatural base, a derivative thereof, and a nucleic acid containing a nucleotide having the unnatural base. The present invention also relates to a method of preparing the nucleic acid. The unnatural base of the present invention has excellent fluorescence characteristics and also has excellent properties as a universal base.
