Triazine‐Naphthalimide Cage for the Recognition of Nucleotides and Parallel G‐Quadruplex

ChemistryEurope, Volume 4, Issue 3, March 2026.
A cage‐like receptor is designed by combining a triazine‐based macrocycle with a naphthalimide dye. The modular construction enables the recognition of various sites on the G‐quadruplex, specifically the phosphate residues and guanine quartets. This design approach provides strong and selective binding of parallel G‐quadruplex over double‐stranded DNA ...
