title: A microfluidic platform to synthesize a G-quadruplex binding ligand.
abstract: An aromatic triarylpyridine chromophore promotes pi-stacking interactions with the terminal G-tetrad in quadruplex DNA, stabilizing the structure and presenting a pathway towards cancer treatment by inhibition of telomerase. An interesting parent compound in this class is the dimethylamino functionalised 4'-aryl-2,6-bis(4-aminophenyl)pyridine. However, access to this compound using traditional batch synthetic methodology is limited, due to thermodynamic and kinetic constraints. A novel approach to the synthesis of this compound has been developed, involving dynamic thin films, overcoming a series of competing reactions, effectively controlling chemical reactivity and selectivity.
