Mismatched bulges in nucleic acid constructs are important in the recognition event between biological molecules. Herein, it is observed that napthyridine dimer 2 is able to specifically bind G-G mismatches in all nucleic acid constructs comprising of RNA-RNA, RNA-DNA and DNA-DNA duplexes. However, the binding affinity of 2 is strongest toward DNA duplex, followed by RNA-DNA heteroduplex and RNA duplex being the weakest binding partner. Nonetheless, this binding behavior suggests that the binding process primarily occurs between the guanine base pairs and the napthyridine moiety, and is independent of the tertiary structure of the nucleic acid duplexes.
