A novel dual-emission fluorescent probe for the simultaneous detection of H2S and GSH
1Key Laboratory of Chemical Biology of Hebei Province, College of Chemistry and Environmental Science, Hebei University, Baoding 071002, China.
Abstract:
A novel chlorinated coumarin-malononitrile fluorescent probe with three potential reaction sites, which exhibited highly selective, rapid response, low detection limit, and was capable of the simultaneous detection of H2S (λex/em = 515/564 nm) and GSH (λex/em = 430/517 nm), was first proposed. The probe was successfully applied to dual-channel imaging H2S and GSH in MCF-7 cells.
