The fluorogenic synthesis of a sym. or unsym. trimethine cyanine dye by an aldolization-elimination reaction between two nonfluorescent precursors was applied for sensing G-quadruplex formation in vitro. Two peptide nucleic acids PNAs were designed that can each hybridize in a sequence-specific manner with five nucleobases upstream and five nucleobases downstream of the parallel-stranded ckit21T quadruplex chosen as a model system. They were functionalized at their C-terminal or N-terminal end with either an N-alkyl-2-methyleneindoline (Ind1-3) or an N-alkyl-2-(3,3-dimethylindolin-2-ylidene)acetaldehyde (Aid). Two ε-N,N-dimethyllysine residues per PNA strand were also added to ensure solubility of both PNAs in water at near-physiol. pH.
