Fluorescent trimethyl-substituted naphthyridine as a ligand for C–C mismatch detection in CCG trinucleotide repeats†
Abstract
We report on the selective binding of 2-amino-5,6,7-trimethyl-1,8-naphthyridine (ATMND) to C–C mismatch present in the hairpin structures of (CCG)n trinucleotide repeats that are associated with neurological diseases; this binding is accompanied by significant fluorescence quenching of ATMND.
