Two-photon fluorescent probe for detection of Cysteine

摘要

The present invention relates to a two-photon fluorescent probe compound represented by the following formula (1) for selectively recognizing cysteine by distinguishing between homocysteine and glutathione in living cells and tissues. The two- It has permeability and low photo-cytotoxicity. TPM can selectively identify cysteine distribution in living tissues without interfering with other biologically relevant substances. It can be used as an effective tool for recognition of intracellular cysteine, RTI ID = 0.0 and / or / RTI [Chemical Formula 1]
