Improved photostable FRET-competent biarsenical-tetracysteine probes based on fluorinated fluoresceins.

Journal of the American Chemical Society, 2006
We have developed fluoro-substituted versions of the biarsenical-tetracysteine label FlAsH, exhibiting significant improvements in important properties over the original fluorescein derivative. In complexes with tetracysteine targets, F2FlAsH exhibits 50

Mild synthesis of asymmetric 2'-carboxyethyl-substituted fluoresceins.

Journal of Organic Chemistry, 2008
Asymmetric fluoresceins bearing a carboxyethyl group in the chromophoric portion of the dyes were prepared by a reaction of substituted phthalic anhydride with a carboxyethyl substituted resorcinol analogue followed by a condensation with a second ...

CELL MEMBRANE PHOTOMODIFICATION: RELATIVE EFFECTIVENESS OF HALOGENATED FLUORESCEINS FOR PHOTOHEMOLYSIS

Photochemistry and Photobiology, 1982
— Relative potency of 10 fluorescein derivatives as sensitizers of delayed photohemolysis of human erythrocytes has been assessed. Dilute suspensions of washed cells were illuminated in the presence of sensitizer at different concentrations for 1 h and ...

Inhibition of housefly oxidative detoxication by phthaleins, fluoresceins and related compounds.

Xenobiotica; the fate of foreign compounds in biological systems, 1981
1. Phenolphthalein, halogenated fluoresceins, and other triphenylmethane and diphenylmethane derivatives inhibited biphenyl hydroxylation, aldrin epoxidation and several O-dealkylations in insect abdomen homogenates.

Biotransformation of di-n-butyl phthalate by a psychrotrophic Pseudomonas fluoresceins (BGW) isolated from subsurface environment

, 1995
A psychrotrophic denitrifying Pseudomonas fluorescens was isolated from an unamended subsurface microcosm incubated at 10 °C for 43 days. This pseudomonad transformed di-n-butyl phthalate at 10 °C in a chemically defined medium under both aerobic and ...

THE EFFICIENCY OF HALOGENATED FLUORESCEINS AS SENSITIZERS FOR THE PHOTODYNAMIC IN ACTIVATION OF TRYPSIN *

, 1971
MOST ENZYMES are inactivated on illumination in the presence of an appropriate sensitizing 'dye' and molecular oxygen. This phenomenon is termed 'photodynamic action' by biologists [ 11.

A Fluorinated Carbanionic Substituent for Improving Water-solubility and Lipophilicity of Fluorescent Dyes.

Angewandte Chemie, 2020
Installation of a carbanionic substituent, that is strongly stabilised by two (trifluoromethyl)sulfonyl (Tf = SO 2 CF 3 ) groups, into several fluorescence dyes including boron-dipyrromethenes (BODIPYs), fluoresceins, and aminocoumarins has been achieved

Novel Derivatization of Protein Thiols with Fluorinated Fluoresceins

, 1996
Fluorescein diacetate analogs 3a–3c are shown to react selectively with protein sulfhydryl groups at neutral pH in aqueous solution, by means of substitution at the perfluorinated ring. The acetate moieties are cleaved by treatment with aqueous carbonate

Evolution of fluorescein as a platform for finely tunable fluorescence probes.

Journal of the American Chemical Society, 2005
Fluorescence imaging is the most powerful technique currently available for continuous observation of dynamic intracellular processes in living cells. Suitable fluorescence probes are naturally of critical importance for fluorescence imaging, but only a ...
