Reactions of glutathione and glutathione radicals with benzoquinones
Free Radical Biology and Medicine, 1992The reactions of glutathione (GSH) and glutathione radicals with a series of methyl-substituted 1,4-benzoquinones and 1,4-benzoquinone have been studied. It was found that by mixing excess benzoquinone with glutathione at pH above 6.5, the products formed were complex and unstable. All of the other experiments were carried out at pH 6.0, where the main

Transport of glutathione and glutathione conjugates by MRP1
Trends in Pharmacological Sciences, 2006Glutathione (GSH)-conjugated xenobiotics and GSH-conjugated metabolites (e.g. the cysteinyl leukotriene C4) must be exported from the cells in which they are formed before they can be eliminated from the body or act on their cellular targets. This efflux is often mediated by the multidrug resistance protein 1 (MRP1) transporter, which also confers drug

Inhibition of glutathione disulfide reductase by glutathione
Archives of Biochemistry and Biophysics, 1991Rat-liver glutathione disulfide reductase is significantly inhibited by physiological concentrations of the product, glutathione. GSH is a noncompetitive inhibitor against GSSG and an uncompetitive inhibitor against NADPH at saturating concentrations of the fixed substrate.

Glutathione and glutathione analogues; Therapeutic potentials
Biochimica et Biophysica Acta (BBA) - General Subjects, 2013Glutathione (GSH) and related enzymes are critical to cell protection from toxins, both endogenous and environmental, including a number of anti-cancer cytotoxic agents.Enhancing GSH and associated enzymes represents a longtime and persistent aim in the search for cytoprotective strategies against cancer, neurologic degeneration, pulmonary and ...

Glutathione and glutathione metabolizing enzymes in yeasts
Antonie van Leeuwenhoek, 1988Total glutathione content, glutathione peroxidase, glutathione transferase and glutathione reductase activities have been measured in 12 species of yeasts. All the strains tested contained glutathione, though in different amounts, as well as the above mentioned enzymes.

Measurement of Glutathione and Glutathione Disulfide
Current Protocols in Toxicology, 1999AbstractMeasurements of glutathione should include quantification of both the reduced and oxidized forms. HPLC‐based assays for glutathione and other cellular thiols and disulfides utilize a variety of detection methods, including ultraviolet, fluorescence, and electrochemical methods.

Glutathione Peroxidase and Glutathione Reductase Activities toward Glutathione-Derived Antioxidants
Biochemical and Biophysical Research Communications, 1994A new class of glutathione derivatives with antioxidant properties has been prepared by transformation of the NH2 group into a pyrrole ring with various substitutions at the 2 and 5 positions. Due to steric hindrance and/or hydrophobicity of the 2-5-disubstituted pyrrole ring, the reduced glutathione derivatives are poor substrates of the glutathione ...

Nanoformulations that can respond to the specific tumor microenvironment (TME), such as a weakly acidic pH, low oxygen, and high glutathione (GSH), show promise for killing cancer cells with minimal invasiveness and high specificity.

Glutathione (GSH) is synthesized in the cytoplasm but there is a requirement for glutathione not only in the cytoplasm, but in the other organelles and the extracellular milieu. GSH is also imported into the cytoplasm. The transports of glutathione across these different membranes in different systems have been biochemically demonstrated.

Antioxidants & Redox Signaling, 2017
Glutathione degradation has for long been thought to occur only on noncytosolic pools. This is because there has been only one enzyme known to degrade glutathione (γ-glutamyl transpeptidase) and this localizes to either the plasma membrane (mammals, bacteria) or the vacuolar membrane (yeast, plants) and acts on extracellular or vacuolar pools. The last
