AZD8055 is a novel ATP-competitive inhibitor of mTOR kinase (both complexes mTORC1 and mTORC2) with an IC50 of 0.8 nM.Particularly,AZD8055 fully inhibited multisite eIF4E-binding protein1 phosphorylation,subsequently blocking protein translation, which was in contrast to the effects of rapamycin. In addition, the mTORC1-dependent PI3K/Akt feedback activation was fully abrogated in AZD8055-treated AML cells. Significantly, AZD8055 decreased AML blast cell proliferation and cell cycle progression, reduced the clonogenic growth of leukemic progenitors and induced caspase-dependent apoptosis in leukemic cells but not in normal immature CD34+ cells.

| Results | we found a modest, but significant, correlation between BIM expression and sensitivity to ABT-263.ABT-263 across both data sets (SI Appendix, Fig. S1 B and C). However, the ratio of BIM to MCL-1 predicted sensitivity to ABT-263 more effectively than the expression of either biomarker alone. SCLC lines have increased BIM expression compared with other solid tumor types along with enhanced sensitivity to ABT-263 compared with other solid tumor types across a large panel of cancer cell lines. |

| Cell lines | H838 and A549 cells line |
| Preparation method | Growth inhibition and autophagy analysis. For growth inhibition and acridine staining, cells were exposed to increasing concentrations of AZD8055 for 72 to 96 h and stained for cell nuclei (0.03 mg/mL Hoechst 33342) and acidic vesicles (1 μg/mL acridine orange). Images were captured at 450 and 536 nm on an ArrayScan II (Cellomics) platform, and the percentage of acidic vesicles and the number of cells were quantified. For LC3 assessment, cells were exposed to e64d/pepstatin (10 μg/mL) for 30 to 90 min before incubation with AZD8055. Cells were lysed on ice and analyzed by immunoblotting. |
