摘要: Cysteine is an important regulator of redox processes. Due to the nucleophilic and oxidative sensitivity, cysteine residues in proteins can be oxidized by intracellular reactive oxygen species (ROS), which can lead to protein structural and functional changes. Hence, the development of fluorescent probes to image cysteine and cysteine oxidation is of great significance for the study of redox homeostasis in living system. In this review, the development of fluorescent probes for imaging cysteine and cysteine oxidation was summarized. Moreover, we further analyzed defects of the reported fluorescent probes and made suggestions for the future development of fluorescent probes. We expect that this review can not only provide a deeper understanding of the role of cysteine and cysteine oxidation in oxidative stress, but also broaden the application of fluorescent probes in imaging cysteine and cysteine oxidation.
