L- Buthionine Sulfoximine-CAS 83730-53-4-Calbiochem

产品说明

一般描述

A cell-permeable, sulfoximine based compound that acts a potent, fast acting, irreversible inhibitor of g-glutamylcysteine synthetase and depletes cellular glutathione levels. Closely resembles the structure of g-glutamylphosphate cysteine adduct. The inhibition follows the first order kinetics with t1/2 = ~ 11 sec at saturating inhibitor concentration. Does not affect the activity of glutamine synthetase. Shown to improve the outcome of chemotherapy by lowering the levels of glutathione in cancer cells (IC₅₀ = 1.9, 8.6, and 29 µM in melanoma, breast, and ovarian tumor cells, respectively).
