Chromatographic separation of fluorescent thiol adducts of 4-chloro-7-sulphobenzofurazan. Use as substrates for enzymes of the mercapturic acid xenobiotic pathway.

X P Chen et al.

Journal of chromatography. B, Biomedical sciences and applications, 709(1), 19-25 (1998-07-08)

Fluorescent adducts of 4-chloro-7-sulphobenzofurazan with cysteine, cysteinylglycine, reduced glutathione and N-acetylcysteine were prepared. Adducts were separated by HPLC on a 3-mm Nova-Pak C18 reversed-phase column using isocratic elution with a solvent of acetonitrile-0.15 M phosphoric acid (5:95) buffered at pH

The nature of the reaction of an essential tyrosine residue of bovine heart mitochondrial ATPase with 4-chloro-7-nitrobenzofurazan and related compounds.

R Sutton et al.

European journal of biochemistry, 142(2), 387-392 (1984-07-16)

Bovine heart mitochondrial ATPase is inhibited after covalent modification with 4-chloro-7-nitrobenzofuroxan. The kinetics of the reaction are indistinguishable from those for the reaction of an essential tyrosine residue of the ATPase with 4-chloro-7-nitrobenzofurazan that have been described previously [Ferguson et

Ammonium 4-chloro-7-sulfobenzofurazan: a new fluorigenic thiol-specific reagent.

Archives of biochemistry and biophysics, 214(1), 386-396 (1982-03-01)

Ammonium 4-chloro-7-sulfobenzofurazan: a fluorescent substrate highly specific for rat glutathione S-transferase subunit 3.

R M Bolton et al.

Analytical biochemistry, 216(2), 418-423 (1994-02-01)

Ammonium 4-chloro-7-sulfobenzofurazan (Sbf-Cl) is a water-soluble fluorescent reagent which is highly specific for thiol groups. We describe here a simple and sensitive fluorescence assay which is highly specific for subunit 3 of the rat glutathione S-transferases. Specific activities of isoenzymes

Quercetin Increases Hepatic Homocysteine Remethylation and Transsulfuration in Rats Fed a Methionine-Enriched Diet.

Bin Meng et al.

BioMed research international, 2015, 815210-815210 (2015-11-12)

This study was aimed at investigating the effects of quercetin on mRNA expression and activity of critical enzymes in homocysteine metabolism in rats fed a methionine-enriched diet. Rats were fed for 6 weeks the following diets, that is, control, 0.5%
