A Fast Dual-responsive OFF-ON Fluorescent Probe for Cysteine and Glutathione without Interference from Homocysteine

Multi-stimuli-responsive molecular fluorescent probes for bioapplications

“…69 molecular probes have been developed using cellular biothiols as targets. 72,73 For example, Zhang et al designed probe 13 based on a ruthenium(II) complex, which can detect GSH and Cys/Hcy and discriminate these biothiols through the remarkable difference in their luminescence colors (Fig. 7).…”

Synthesis of a Maleimide-Diaminoterephthalate Fluorescence Dye as a ‘Turn-On’ Probe for the Detection of Thiols

“…A DMSO/water mixture (3:2) is also applied for probing cysteine, homocysteine, and glutathione (GSH). 15 Therefore, we also acquired absorption and emission spectra of compounds 8 and 9 in DMSO and DMSO/water (1:1).…”
