Inhibition of glutathione reductase by plant polyphenols
Biochemical Pharmacology, 1997The effects of forty-one plant polyphenols on the activity of glutathione reductase (GSH-RD) were studied. These polyphenols showed varying degrees of concentration-dependent inhibition on the enzyme, with IC50 values that varied from approximately 40 microM to 1 mM.

A Comparative Study with Colchicine on Glutathione Reductase
The Protein Journal, 2010Colchicine is a drug used for the treatment of FMF, primary biliary cirrhosis, psoriasis, Behçet's disease, aphthous stomatitis. Glutathione reductase (GR; E.C 1.6.4.2) is a crucial enzyme which reduces glutathione disulphide to the sulfhydryl form GSH by the NADPH-dependent reduction, which is an important cellular antioxidant system.

Characterization of human platelet glutathione reductase
Biochimica et Biophysica Acta (BBA) - Enzymology, 1978Glutathione reductase (NAD(P)h:oxidized glutathione oxidoreductase, EC 1.6.4.2) has been purified 1000-fold from the cytoplasmic fraction of human platelets. Salts, including the heretofore unreported effect of sodium citrate, activate the NADPH-dependent reduction of oxidized glutathione.

Glutathione reductase from Rhodospirillum rubrum
Archiv f�r Mikrobiologie, 1969Glutathione reductase (NADPH1: glutathione oxidoreductase (EC 1.6.4.2) was purified 70 fold from Rhodospirillum rubrum by ammonium sulfate fractionation, gelfiltration with Sephadex and chromatography on DEAE-cellulose. The optimum pH of the reaction is 7.5–8.2 Kmvalues of 8.4×10−6 M for NADPH and 5.8×10−5 M for GSSG were determined.

[202] Glutathione reductase (Yeast)
1971Publisher Summary This chapter discusses the methods of preparation of Glutathione Reductase (Yeast). Enzymatic activity is measured spectrophotometrically by observing the rate of decrease in absorbance of TPNH at 340 mμ. One unit of enzyme is defined as that amount of enzyme which catalyzes the oxidation of 1 micromole of TPNH per minute at 25 ...
