    제품 설명

    DL-Buthionine-(S,R)-sulfoximine is a potent inhibitor of glutamylcysteine synthetase biosynthesis.

    IC50 & Target

    glutamylcysteine synthetase[1]
    In Vitro

    Buthionine sulfoximine is an analogs of methionine sulfoximine and inhibits gamma-glutamylcysteine synthetase about 20 times more effectively than prothionine sulfoximine and at least 100 times more effectively than methionine sulfoximine[1].

    In Vivo

    Treatment of mice bearing HT1080 and HT1080/DR4 xenografts with a continuous i.v infusion of nontoxic doses of D,L-Buthionine-(S,R)-sulfoximine (300 and 600 mg/kg/day) produce a 60% reduction of GSH plasma levels and greater than 95 % reduction in GSH tumor levels in both parental and multidrug-resistant tumors[2].

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
