L-BUTHIONINE-(SR)-SULFOXIMINE

Research use only, not for human use.

L-Buthionine-(SR)-sulfoximine is a cell-permeable and irreversible inhibitor of γ-glutamylcysteine synthetase (Ki <100 μM) that induces oxidative stress in cells by depleting GSH.

Animal Model:C57BL/6J pun/pun mice.Dosage:2 mM L-Buthionine-(S,R)-sulfoximine (BSO), 20 mM BSO, 2 mM BSO and 20 mM NAC, 20 mM NAC or unsupplemented water for 18 days from 0.5 to 18.5 d.p.c. The pH of supplemented water is as follows: 6.88, 20 mM BSO; 3.37, 2 mM BSO; 2.65, 2 mM BSO plus 20 mM NAC; and 2.58, 20 mM NAC. The pH of regular water used in our facility is ~4. Administration:Drinking water.Result:The average number of eye-spots (mean±SEM) is 5.36±0.29 (n=46), 7.79±0.45 (n=34) and 8.78±0.61 (n=32) in untreated controls, 2 mM L-Buthionine-(S,R)-sulfoximine (BSO) and 20 mM BSO treated mice, respectively. The 2 mM BSO treatment results in ~30% more eye-spots, and the 20 mM treatment results in 40% more eye-spots compared with untreated mice.
