Phen‐DC3 is a highly promising compound that specifically targets G‐quadruplexes, with potent biological effects observed in vivo. We used NMR spectroscopy to solve the structure of the complex formed between Phen‐DC3 and an intramolecular G‐quadruplex derived from the c‐myc promoter. Structural information revealed that Phen‐DC3 interacts with the quadruplex through extensive π‐stacking with guanine

Syntheses and telomeric G-quadruplex-DNA binding properties of novel bisquinolinium compounds are reported. This series exhibits remarkable efficiency both in terms of stabilization and selectivity, thus combining the performances of the most potent quadruplex binders reported so far. These bisquinolinium compounds then represent an ideal tradeoff between rapid synthetic access and efficient target recognition. The study also highlights important structural parameters that lead to the design of highly selective G-quadruplex binders.
