Abstract
As a signal molecule involved in autophagy, hydrogen sulfide (H2S) is considered to be essential in the development and treatment of diseases. In order to clarify the complex role of H2S in organism and the participation of H2S in disease process, it is urgently needed to visualize the dynamics of H2S. In this contribution, a water-soluble near-infrared (695 nm emission) self-immolative fluorescent probe CySO3N3 was constructed for H2S detection. The ability of self-immolative strategy to detect H2S was verified to increase the metabolic capacity and reduce the toxicity of probe. This probe can not only be used to detect H2S in living cell and mice, but also shows great potential in detecting H2S changes to monitor cell self-repair during inflammation and myocardial injury.
