Bioactivity

• Target IC50:
  PI3Kγ:0.42 μM|mTOR:4 nM|DNA-PK:1 μM|PI3Kα:1.3 μM|mTORC2:65 nM|mTORC1:22 nM
• In Vivo:
  In GEO colorectal xenograft, OSI-027 (65 mg/kg) inhibits both mTORC1 and mTORC2 effectors, including 4E-BP1, Akt, and S6 phosphorylation. furthermore , mTORC1 and mTORC2 Inhibition together by OSI-027 potently inhibits tumor growth more than mTORC1 Inhibition by rapamycin.
• In Vitro:
  OSI-027 show the Selective and ATP competitive Inhibition activities against mTORC1 and mTORC2 with IC50 of 22 nM and 65 nM, respectively In addition, OSI-027 inhibits mTOR signaling of phospho-4E-BP1 with an IC50 of 1 μM in cell-based assays. OSI-027 exhibits anti Proliferative activities against several acute leukemia cell lines of myeloid/megakaryocytic origin in a dose-dependent manner, including U937, KG-1, KBM-3B, ML-1, HL-60, and MEG-01 cells. A recent study shows that Inhibition of mTORC1/2 by OSI-027 effectively suppresses phosphorylation of Akt (S473) and cell proliferation in breast cancer cells.
• Cell Research:
  Inhibition of proliferation is measured usin the Cell Titer Glo Assay , as noted in figure legends. To generate dose–response curves, cell lines are seeded at a density of 5,000 cells per well in a 96-well plate. After 24 hours of plating, cells are dosed with varying concentration of either OSI-027 or rapamycin the signal for Cell Titer Glo Assay is determined 72 hours after dosing and normalized to that of Vehicle-treated controls. Inhibition of proliferation, relative to Vehicle-treated controls, is expressed as a fraction of 1 and graphed using PRISM software. (Only for Reference)
