  • Inhibitors of tyrosine kinase receptor suppressed the in vitro angiogenesis of HUVECs. The angiogenesis of HUVECs was evaluated in the absence (control in A) or presence of CP-673451 (5 nM), a selective inhibitor of PDGFR or E7080 (50 nM), an active inhibitor for multiple tyrosine kinase receptors for 6 h. The two agents only inhibit the kinase activity of the relative tyrosine kinase receptors, but do not cause a toxic effect to the cells in the concentration used in this study (Roberts et al., 2005 ; Wiegering et al., 2014). For quantification, the values for the pattern recognition, branch point and total capillary tube length are described in the Methods section. Representative microscopic fields are shown in Panel A. The suppressive effects of the inhibitors on angiogenesis of HUVECs are shown in B, C and D. The data are expressed relative to that of the control cells without exposure to the inhibitor. N = 5, *P < 0.05 and **P < 0.01 versus the control cells.

E7080, as a potent inhibitor of in vitro angiogenesis, shows a significantly inhibitory effect on VEGF/KDR and SCF/Kit signaling. According to the in vitro receptor tyrosine and serine/threonine kinase assays, E7080 inhibits Flt-1, KDR, Flt-4 with IC50 of 22, 4.0 and 5.2 nM, respectively. In addition to these kinases, E7080 also inhibits FGFR1 and PDGFR tyrosine kinases with IC50 value of 46, 51 and 100 nM for FGFR1, PDGFRα and PDGFRβ, respectively. [1] E7080 potently inhibits phosphorylation of VEGFR2 (IC50, 0.83 nM) and VEGFR3 (IC50, 0.36 nM) in HUVECs which is stimulated by VEGF and VEGF-C, respectively. [2] A recent study shows that E7080 treatment (both at 1 μM and 10 μM) results in a significant inhibition of cell migration and invasion by inhibiting FGFR and PDGFR signaling. [3]

体内試験 When orally administrated in a H146 xenograft model, E7080 inhibits the growth of H146 tumor at 30 and 100 mg/kg in a dose-dependent manner and leads to tumor regression at 100 mg/kg. Furthermore, E7080 at 100 mg/kg decreases microvessel density more than anti-VEGF antibody and imatinib treatment. [1] E7080 significantly inhibits local tumor growth in a MDA-MB-231 mammary fat pad (m.f.p.) model with RTVs (calculated tumor volume on day 8/tumor volume on day 1) of 0.81, and reduces both angiogenesis and lymphangiogenesis of established metastatic nodules of MDA-MB-231 tumor in the lymph nodes.

In vitro kinase assay [1]:

Tyrosine kinase assays are performed by HTRF (KDR, VEGFR1, FGFR1, c-Met, EGFR) and ELISA (PDGFRβ), using the recombinant kinase domains of receptors. In both assays, 4 μL of serial dilutions of E7080 are mixed in a 96-well round plate with 10 μL of enzyme, 16 μL of poly (GT) solution (250 ng) and 10 μL of ATP solution (1 μM ATP) (final concentration of DMSO is 0.1%). In wells for blanks, no enzyme is added. In control wells no test article is added. The kinase reaction is initiated by adding ATP solution to each well. After 30-minute incubation at 30°C, the reaction is stopped by adding 0.5 M EDTA (10 μL/well) to the reaction mixture in each well. Dilution buffer adequate to each kinase assay is added to the reaction mixture. In the HTRF assay, 50 μL of the reaction mixture is transferred to a 96-well 1/2 area black EIA/RIA plate, HTRF solution (50 μL/well) is added to the reaction mixture, and then kinase activity is determined by measurement of fluorescence with a time-resolved fluorescence detector at an excitation wavelength of 337 nm and an emission wavelengths of 620 and 665 nm. In the ELISA, 50 μL of the reaction mixture is incubated in avidin coated 96-well polystyrene plates at room temperature for 30 minutes. After washing with wash buffer, PY20-HRP solution (70 μL/well) is added and the reaction mixture is incubated at room temperature for 30 minutes. After washing with wash buffer, TMB reagent (100 μL/well) is added to each well. After several minutes (10–30 minutes), 1 M H3PO4 (100 μL/well) is added to each well. Kinase activity is determined by measurement of absorbance at 450 nm with a microplate reader.

E7080 and either VEGF (20 ng/mL) or FGF-2 (20 ng/mL) containing 2% fetal bovine serum and PDGFβ (40 ng/mL) are added to each well. Cells are incubated for 3 days and then the ratios of surviving cells are measured by WST-1 reagent. For proliferation assay, samples are duplicated and three separate experiments are done.
