S-nitrosylation is a posttranslational modification of protein cysteine residues leading to the formation of S-nitrosothiols and its detection is crucial to understanding of redox regulation and NO-based signaling. Prototypical detection methods for S-nitrosylation are always carried out ex situ. However, the reversible nature and the tendency of transnitrosylation highlight the necessity of its probing in intact live biological contexts. Herein we provide a fluorogenic chemical probe for the detection of S-nitrosylation in live endothelial cells. The probe is weakly emissive alone and becomes highly fluorescent only after undergoing a reaction with S-nitrosothiols in live cellular environments. This probe features high degrees of specificity and desirable sensitivity. Furthermore, it has been successfully applied to image the dynamic change of protein S-nitrosylation in live endothelial cells. The applicability of the probe in complex biological systems has been additionally verified by imaging a known target of S-nitrosylation, glyceraldehyde-3-phosphate dehydrogenase (GAPDH), in live cells. Due to the versatility exemplified, this probe holds great promise for exploring the role of protein S-nitrosylation in the pathophysiological process of a variety of vascular diseases.
