Product information "L-Buthionine-(S,R)-Sulfoximine"
L-Buthionine-(S,R)-sulfoximine is an irreversible inhibitor of gamma-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.
