Description

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.
