OSI-027 shows the selective and ATP competitive inhibition activities against mTORC1 and mTORC2 with IC50 of 22 nM and 65 nM, respectively. In addition, this compound inhibits mTOR signaling of phospho-4E-BP1 with an IC50 of 1 μM in cell-based assays. [1] It 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. [2] A recent study shows that inhibition of mTORC1/2 by this chemical effectively suppresses phosphorylation of Akt (S473) and cell proliferation in breast cancer cells. [3]

Kinase Assay Biochemical assays
mTORC1 and mTORC2 inhibition is assayed using native enzyme complex immunoprecipitated from HeLa lysates at 1 mM ATP. To prepare whole cell lysates from HeLa cells, 25 g cell pellet is lysed in 60 mL of ice-cold buffer A [40 mM HEPES (pH 7.5), 120 mM NaCl, 1 mM EDTA, 10 mM sodium pyrophosphate, 10 mM glycerophosphate, 50 mM NaF, 0.5 mM orthovanadate, and EDTA-free protease inhibitors containing 0.3% CHAPS] for 30 minutes on a magnetic stirrer in a cold room. After clearing of the lysates by centrifugation at 13,000 g for 10 minutes, Protein G-coated 384-well plates are incubated with 0.25 μg of mTOR antibody in 15 μL of buffer A for 1 hour at 4 °C. To each well, 40 μg of HeLa cell lysate in 15 μL of buffer A is added and incubated overnight at 4 °C to immunoprecipitate mTOR complexes. Plates are washed 3 times with buffer A and twice with immunoprecipitation wash buffer [Buffer B: 50 mM HEPES (pH 7.5) and 150 mM NaCl]. OSI-027 is added at 10 μM concentration to each well and DMSO is added to the control wells. The reaction is started by adding 150 ng of His-tagged 4E-BP1 as a substrate in the presence or absence of 100 μM ATP to each well in 25 μL of freshly prepared kinase buffer [Buffer C: 20 mM HEPES (pH 7.5), 10 mM MgCl2, 4 mM MnCl2, 10 mM β-mercaptoethanol, and 200 μM vanadate] and incubated at room temperature (RT) for 30 minutes. The reaction is stopped by transferring 25 μL of reaction mixture from each well to corresponding wells of fresh Ni-chelate-coated plates and incubated overnight at 4 °C followed by 2 hours at 37 °C. To detect phosphorylation of 4E-BP1, the plates are washed once with TBST (Tris-buffered saline containing 0.1% Tween-20) containing 5% skim milk powder. To each well, 25 μL of 1:1,000 diluted phospho-4E-BP1 antibodies in TBST containing 5% skim milk are added and incubated for 1 hour at RT. The plates are washed once with TBST and then 25 μL of anti-rabbit HRP (diluted 1:10,000) in TBST containing 5% skim milk is added. The plates are incubated for 1 hour at RT and washed 5 times with TBST. For detection of phospho-4E-BP1, 25 μL of chemiluminescent reagents A+B is added and chemiluminescence is measured using an Analyst plate reader.

実験の流れ

Inhibition of proliferation is measured using 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 concentrations of either OSI-027 or this compound. 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.

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 this compound potently inhibits tumor growth more than mTORC1 inhibition by rapamycin. [1]
