Description and Uses
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.
L-Buthionine-(S,R)-sulfoximine is a potent and specific inhibitor of alpha-glutamylcysteine synthetase.
