Description

Application

L-Buthionine-sulfoximine has been used:

• as a selective activator for the induction of ferroptosis in rat apoptotic cells
• as an inhibitor of γ-glutamylcysteine synthetase to study its effects on the viability and effectiveness of microspore embryogenesis (ME) induction in triticale and barley
• as a glutathione synthesis blocker to study its effects on auranofin (AFN)-mediated interleukin-1β expression in murine alveolar macrophages

Used to induce experimental glutathione deficiency, to investigate roles of glutathione in cellular processes.

Biochem/physiol Actions

Blocks cellular resistance to chemotherapy by inhibiting γ-glutamylcysteine synthetase, a key enzyme in glutathione biosynthesis. Used to induce experimental glutathione deficiency, to investigate roles of glutathione in cellular processes.
