Sensing technologies based on Peptide Nucleic Acids (PNAs) and oligonucleotide-templated chemistry are perfectly suited for biomedical applications (e.g., diagnosis, prognosis and stratification of diseases) and could compete well with more traditional amplification technologies using expensive dual-labelled oligonucleotide probes. PNAs can be easily synthesised and functionalised, are more stable and are more responsive to point-mutations than their DNA counterpart. For these reasons, fluorogenic PNAs represent an interesting alternative to DNA-based molecular beacons for sensing applications in a cell-free environment, where cellular uptake is not required.

Mahmood T, Wu Y, Loriot D, Kuimova M, Ladame Set al., 2012, Closing the ring to bring up the light: synthesis of a hexacyclic acridinium cyanine dye., Chemistry, Vol: 18, Pages: 12349-12356

The synthesis of a geometrically constrained and near-planar hexacyclic acridinium cyanine dye 9 is reported. When compared to its unlocked and non-fluorescent monomethine cyanine dye analogue 3, this photostable dye emits in the green area of the spectrum with a remarkable quantum yield close to unity in organic solvents and above 0.5 in water. A detailed steady-state and time-resolved spectroscopic study revealed that dye 9 forms emissive aggregates in water, which are responsible for a red-shifted and broadened emission band and longer emission lifetime, τ≈33 compared to 6.5-7.0 ns for the monomeric dye. Dye 9 also binds strongly to DNA (both duplex and quadruplex) in its monomeric form and is very efficiently taken up by cells, in which it accumulates primarily into the nucleus.
