WebMar 7, 2024 · Graphical Abstract All together now: A novel fluorescent probe was developed for simultaneous sensing of cysteine (Cys), homocysteine (Hcy), and glutathione (GSH). Featuring four binding sites and different reaction mechanisms for different biothiols, this probe exhibited rapid fluorescence turn-on for distinguishing Cys, Hcy, and GSH. WebBiothiols such as cysteine (Cys), homocysteine (Hcy) and glutathione (GSH) play important roles in various physiological and pathological processes, and due to their similar structures and reaction activities, it is still challenging to simultaneously discriminate between GSH and Cys/Hcy in vivo.
