The first latent green fluorophores for the detection of azoreductase activity in bacterial cultures.
Résumé
An efficient synthesis of original bio-reductive probes suitable for the detection of azoreductases from the fluorescent rhodamine 110 dye is presented. A "turn-on" green fluorescence response upon reduction of the two diazo bonds of these latent fluorophores was observed both in vitro and in the context of bacterial cultures.
