L-Buthionine-sulfoximine

L-buthionine-sulfoximine is a cell-permeable, potent, fast-acting, irreversible g-glutamylcysteine synthetase inhibitor that consumes endogenous endogenous intracellular copper chelating agent glutathione. Sensitized cells to cell death induced by Elesclomol-copper, and the efficacy of statin inhibitors was enhanced by combination.
