L-BUTHIONINE-(S,R)-SULFOXIMINE Chemical Properties,Uses,Production
Description
L-Buthionine-(S,R)-sulfoximine is an irreversible inhibitor of γ-glutamylcysteine synthetase (Ki <100 μM), the rate-limiting enzyme for L-glutathione (GSH) synthesis, that induces oxidative stress in cells by depleting GSH. Administration of L-buthionine-(S,R)-sulfoximine leads to decreased GSH levels in virtually all tissues and is associated with tissue damage and apoptosis. Whereas elevated glutathione levels are associated with tumor cell resistance, L-buthionine-(S,R)-sulfoximine has been shown to enhance the toxicity of various chemotherapeutic agents in drug-resistant tumors.
Chemical Properties
White Crystalline Solid
Uses
L-Buthionine-(S,R)-sulfoximine is a potent and specific inhibitor of alpha-glutamylcysteine synthetase.
Uses
Buthionine sulfoximine (BSO) is an irreversible inhibitor of γ-glutamylcysteine synthetase (Ki <100 μM), the rate-limiting enzyme for L-glutathione (GSH) synthesis, that induces oxidative stress in cells by depleting GSH. Administration of BSO leads to decreased GSH levels in virtually all tissues and is associated with tissue damage and apoptosis. Whereas elevated glutathione levels are associated with tumor cell resistance, BSO has been shown to enhance the toxicity of various chemotherapeutic agents in drug-resistant tumors.
Uses
inhibitor of gamma-glutamylcysteine synthetase
Definition
ChEBI: L-buthionine-(S,R)-sulfoximine is a 2-amino-4-(S-butylsulfonimidoyl)butanoic acid which has S-configuration. It is a inhibitor of gamma-glutamylcysteine synthetase and glutathione (GSH) biosynthesis and is capable of enhancing the apoptotic effects of several chemotherapeutic agents. It has a role as a ferroptosis inducer and an EC 6.3.2.2 (glutamate--cysteine ligase) inhibitor.
Hazard
A reproductive hazard.
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.
storage
Store at -20°C
