L-Buthionine-(S,R)-sulfoximine is a cell-permeable, irreversible inhibitor of g-glutamylcysteine synthetase[1].
In ZAZ and M14 melanoma cell line, L-Buthionine-(S,R)-sulfoximine (50 μM) treatment for 48 hr results in a 95% decrease in GSH levels, and a 60% decrease in GST enzyme activity. GST-mu protein and mRNA levels are significantly reduced in both cell lines[1].
L-Buthionine-(S,R)-sulfoximine (BSO) treatment significantly increases the frequency of DNA deletions and reduces concentrations of GSH and cysteine. BSO (20 mM) treatment results in a 40% increase in DNA deletion frequency, a 70% decrease in GSH, and a 55% decrease in cysteine levels[2].
