Description

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.
