抄録

We have successfully developed a class of ligand that exhibits a fluorescence-enhancement upon binding to pyrimidine bases opposite an AP site in DNA duplexes. The present ligand, Naph-c3-DBD, in which DBD (7-N,N-dimethylaminosulfonylbenzo-2-oxa-1,3-diazole) is connected to 2-amino-7-methyl-1,8-naphthyridine by a propylene linker, is capable of selectively binding to pyrimidine bases over purine bases, and the binding event is accompanied by a significant enhancement of emission due to the DBD moiety (emission maximum at 597 nm). The response of the ligand is almost specific to pyrimidine bases, making it possible to detect pyrimidine/purine transversion.
