SU11274 inhibits the phosphorylation of key regulators of the PI3K pathway,including AKT, FKHR, or GSK3β. SU11274 treatment inhibits the growth of TPR-MET-transformed BaF3 cells in a dose-dependent manner with IC50 of < 3 μM in the absence of interleukin 3, without growth inhibition of BaF3 cells.transformed by other oncogenic tyrosine kinases, including BCR-ABL, TEL-JAK2, TEL-ABL, andTEL-PDGFβR. In addition to cell growth, SU11274 treatment significantly inhibits the migration of BaF3. TPR-MET cells by 44.8% and 80% at 1μM and 5μM, respectively.SU11274 inhibits HGF-dependent phosphorylation of Met as well as HGF-dependent cell proliferation and motility with an IC50 of 1-1.5μM. In H69 and H345 cells which have functional Met receptor, SU11274 inhibits the HGFinduced cell growth with IC50 of 3.4μMand6.5μM,respectively.SU11274 induces G1 cell cycle arrest with cells in G1 phase increased from 42.4% to 70.6% at 5μM, and induces caspase-dependent apoptosis by 24% at 1μM. SU11274 inhibits cell viability in c-Met-expressing non-small cell lung cancer (NSCLC) cells with IC50 values of 0.8-4.4μM,andabrogates hepatocyte growth factor-induced phosphorylation of c-Met and its downstream signaling.   推荐实验方法(仅供参考) 激酶实验： A chimeric protein is constructed containing the cytoplasmic domain of human c-Met fused to Glutathione S-transferase(GST) and expressed in SF9 cells. The c-Met kinase GST-fusion protein is used for an ELISA-based Met biochemical assay using the random copolymer poly(Glu:Tyr) (4:1) immobilized on microtiter plates as a substrate. IC50 value is determined with variouscon centrations of SU11274 in a buffer containing 5μM ATP and 10 mM MnCl2, 50mM HEPES (pH 7.5), 25mM NaCl, 0.01% BSA, and 0.1 mM Na orthovanadate. The kinase reaction is performed for 5 minutes at room temperature. The extent of substrate phosphorylation is measured using horseradis peroxidase-conjugated anti-pTyr antibodies.   细胞实验:   Cells are exposed to various concentrations of SU11274 in the presence or absence of HGF for 24, 48, and 72 hours. The number of viable cells is determined using the MTT assay or trypan blue exclusion. Cell Cycle and apoptosis are measured by fluorescence-activated cell sorter analysis via propidium iodide staining and Annexin V-positive staining, respectively.
