Resumen

The novel coumarin-based 'turn-on' fluorescent probe (E)-3-(2,5- dimethoxybenzylideneamino)-7-hydroxy-2H-chromen-2-one (MGM) was designed, synthesized, and characterized. This compound shows high selectivity for Cu ⁺², combined with a large fluorescence enhancement upon binding to Cu ²⁺. Benesi-Hildebrand and Job plots demonstrate that the stoichiometry of the Cu ²⁺ complex formed is 2:1. Preliminary studies employing epifluorescence microscopy demonstrated that Cu ⁺² could be imaged in human neuroblastoma SH-SY5Y cells treated with MGM.
