“…Useful affinity and selectivity for target nucleobases opposite the AP site has been indeed obtained by various kinds of heterocyclic planer compounds, including cytosine-selective 2-amino-1,8-naphthyridine derivatives, [10][11][12][13][14] guanine-selective pterin derivatives, [15][16][17] adenineselective 6,7-dimethyllumazine, 18 and thymine-selective 3,5-diaminopyrazine derivatives. [19][20][21] All of these ligands show a complexation-induced fluorescence signaling, and genotype of samples can be clearly distinguished by combining ligands with selectivity for respective target nucleobases.…”
