Aromatic Core Extension in the Series of N-Cyclic Bay-Substituted Perylene G-Quadruplex Ligands: Increased Telomere Damage, Antitumor Activity, and Strong Selectivity for Neoplastic over Healthy Cells
an extended aromaticcore able to increase the stacking interactions with the terminal tetrad of the G‐quadruplex. The obtained “chimera” molecule, EMICORON, rapidly triggers extensive DNA damage of telomeres, associated with the delocalization of telomeric protein protection of telomeres 1 (POT1), and efficiently limits the growth of both telomerase‐positive and ‐negative tumor cells. Notably, the
