Opis

Application

DL-Buthionine-sulfoximine is suitable for use to:

• examine whether the inhibition of glutathione by BSO enhances the apoptotic effect of estrogen on antihormone-resistant human breast cancer cells[1]
• investigate the effect of BSO on development of bovine embryos[2]
• inhibit GSH in several studies[3][4]
• investigate the effect of GSH synthesis on oocyte maturation[5]

It may be used to inhibit GSH and evaluate the hepatotoxicity and nephrotoxicity of natural food colorants in the absence of GSH

Biochem/physiol Actions

DL-Buthionine-sulfoximine inhibits the biosynthesis of Glutathione (GSH) in liver and other peripheral organs. It does not have any effect on GSH in the CNS.[6] It augments the antiproliferative action of reactive oxygen species (e.g., hydrogen peroxide), and agents that indirectly cause accumulation of reactive oxygen species (e.g., 2-methoxyestradiol, which increases intracellular superoxide anion).[7]
