title: Detection of the C-C mismatched base pair by small ligands.
abstract: We synthesized 2-aminonaphthyridine derivatives that specifically bind to cytosine-cytosine (C-C) mismatch. The binding of ligands was verified by observing an increase of melting temperature for 11-mer duplexes containing a mismatch in the presence of ligands. It was found that the aminonaphthyridine dimer stabilized C-C mismatch more strongly than the monomer.
