Construction of long-wavelength fluorescein analogues and their application as fluorescent probes

Chemistry. 2013 May 17;19(21):6538-45. doi: 10.1002/chem.201300418. Epub 2013 Apr 15.

Abstract

Born to dye: Five fluorescein analogues were synthesised (see scheme). One analogue was found to emit in the NIR region with a high quantum yield, excellent photostability and good permeability. Three derivatives were found to specifically stain mitochondria and one dye responds to thiols with a strong turn-on NIR fluorescence signal and colorimetric change, in vitro and in vivo.
