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
  • investigate the effect of BSO on development of bovine embryos
  • inhibit GSH in several studies
  • investigate the effect of GSH synthesis on oocyte maturation
It may be used to inhibit GSH and evaluate the hepatotoxicity and nephrotoxicity of natural food colorants in the absence of GSH

Actions biochimiques/physiologiques

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. 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).

2-Methoxyestradiol (2-ME), an endogenous metabolite of 17beta-estradiol, induces the intracellular accumulation of superoxide anion (O2*-) and buthionine sulfoximine (BSO) is an inhibitor of glutathione (GSH) synthesis. We have examined the combination anticancer effect of 2-ME and BSO accompanied with hydrogen

Previous studies indicated that DL-buthionine sulfoximine (DL-BSO), an agent that inhibits the biosynthesis of GSH in liver and other peripheral organs, fails to suppress levels of GSH in the CNS. In the current study, preweanling mice responded to repeated injections

Estrogen deprivation using aromatase inhibitors is one of the standard treatments for postmenopausal women with estrogen receptor (ER)-positive breast cancer. However, one of the consequences of prolonged estrogen suppression is acquired drug resistance. Our group is interested in studying antihormone
