A Ratiometric Fluorescent Probe for Rapid Detection of Hydrogen Sulfide in Mitochondria

Abstract

Quick: An exogenously induced quick increase of the H2S concentration (80 s) in MCF-7 cells can be visualized by ratiometric imaging using a new probe (CouMC) that can target mitochondria. CouMC was constructed by combining merocyanine and coumarin fluorophores. The selective nucleophilic addition of HS− to the merocyanine derivative at neutral pH is crucial for the rapid H2S detection.
