inside the culture media entirely rescued A549 cells from each 6S and M2 toxicity, with modified IC50's over 80 M (Figure 5A). Western blot analysis showed that inside the presence of excess GSH, there was no adjust in p53 expression inside the 24 h extracts of cells treated with 40 M 6S or M2 (Figure 5B). These benefits show that the alterations in GSH levels induced by each 6S and M2 in A549 cel
