Abstract

We have synthesized a flavin-N(5)-oxide derivative with a p-toluenesulfonyl (Ts-OF) group as a “turn-on” fluorescent probe for the detection of several antioxidant amino acids and biothiols. Oxidized flavin was synthesized by using dithiothreitol as the reducing agent. Ts-OF showed a light-driven fluorescence enhancement in the presence of several amino acids and biothiols such as histidine (His), methionine (Met), cysteine (Cys), glutathione (GSH), and homocysteine (Hcy). The ¹H NMR study indicated the reductive elimination of the p-toluenesulfonyl group from Ts-OF in the presence of antioxidants and photo-irradiation.
