WeWe discovered MEK inhibitor PD901 plus the panmTOR inhibitor MLN0128 in human HCC cell lines. found that the HCC cells tested were additional sensitive to MLN0128, with IC50 ranging among 0.2 0.25to five , that the HCC cells tested had been a lot more sensitive to MLN0128, with IC50 ranging amongst to M, when compared toto PD901, whichdisplayed a larger IC50, , in between one hundred and 200 (Figure 3A,B). when compared PD901, which displayed higher IC50 between one hundred and 200 M (Figure 3A,B).
