Biological Activity

Description SU11274 (PKI-SU11274) is a selective Met (c-Met) inhibitor with IC50 of 10 nM in cell-free assays, no effects on PGDFRβ, EGFR or Tie2. SU11274 induces autophagy, apoptosis and cell cycle arrest.

In vitro

SU11274 exhibits greater than 50-fold selectivity for Met versus Flk and more than 500 times selectivity versus other tyrosine kinases such as FGFR-1, c-src, PDGFbR, and EGFR. 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, and TEL-PDGFβR. In addition to cell growth, SU11274 treatment significantly inhibits the migration of BaF3. TPR-MET cells by 44.8% and 80% at 1 μM and 5 μM, respectively. SU11274 inhibits HGF-dependent phosphorylation of Met as well as HGF-dependent cell proliferation and motility with an IC50 of 1-1.5 μM. In H69 and H345 cells which have functional Met receptor, SU11274 inhibits the HGF-induced cell growth with IC50 of 3.4 μM and 6.5 μM, respectively. SU11274 induces G1 cell cycle arrest with cells in G1 phase increased from 42.4% to 70.6% at 5 μM, and induces caspase-dependent apoptosis by 24% at 1 μM. [2] SU11274 inhibits cell viability in c-Met-expressing non-small cell lung cancer (NSCLC) cells with IC50 values of 0.8-4.4 μM, and abrogates hepatocyte growth factor-induced phosphorylation of c-Met and its downstream signaling.

HLMVECs grown on slide chambers to ∼95% confluence were pretreated with SU11274 (1 μM, 30 min) prior to stimulation with HGF (20 ng/ml) for 30 min and probed with anti-actin and anti-p-SphK1 (ser225) antibodies, and lamellipodia were examined by immunofluorescence microscopy with 60× oil objective. Co-localization of actin (red) and p-SphK1 (green) in lamellipodia (merge, yellow) was visualized by immunofluorescent staining. Shown are representative images from three independent experiments. Insets depict enhanced actin and p-SphK1 accumulation in lamellipodia that was blocked by SU11274 treatment of cells. 



Kinase Assay:[1]
- Collapse

In vitro Met kinase assay:

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 various concentrations of SU11274 in a buffer containing 5 μM ATP and 10 mM MnCl2, 50 mM HEPES (pH 7.5), 25 mM 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 horseradish peroxidase-conjugated anti-pTyr antibodies.

  • Cell lines: BaF3.TPR-MET, H69 and H345 cells
  • Concentrations: Dissolved in DMSO, final concentrations ~10 μM
  • Incubation Time: 24, 48, and 72 hours
  • Method: 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.
