Biological Activity

Description SKLB1002 is a potent and ATP-competitive VEGFR2 inhibitor with IC50 of 32 nM.
Targets
VEGFR2 [1]
32 nM
In vitro SKLB1002 shows strikingly lower cytotoxicity on normal human cells L-02. SKLB1002 significantly inhibits HUVEC proliferation, migration, invasion, and tube formation, by inhibiting VEGF-induced phosphorylation of VEGFR2 kinase and the downstream protein kinases including ERK, FAK, and Src. [1]
In vivo In the zebrafish embryos, SKLB1002 remarkably blocks the formation of embryonic and tumor-induced angiogenesis with no or least impact on normal cell proliferation. In athymic mice bearing SW620 or HepG2 xenografts, SKLB1002 (100 mg/kg daily, i.p.) causes significant inhibition of tumor growth, inhibits tumor angiogenesis and induces tumor apoptosis. [1] In 4T1 and CT26 tumor model, SKLB1002 and local hyperthermia produce a synergistic antiangiogenesis, anticancer and promotion of apoptosis efficacy. [2]

Protocol (from reference)

Kinase Assay:[1]
  • Kinase inhibition assays

    Kinase inhibition is measured by the use of radiometric assays conducted by Kinase Profiler service. Briefly, in the presence or absence of SKLB1002, VGFR2 (5–10 mU) is incubated in 25-μL reaction solution containing 8 mmol/L 3-(N-morpholino)propanesulfonic acid (MOPS), pH 7.0, 0.2 mmol/L EDTA, 0.33 mg/mL myelin basic protein, 10 mmol/L Mg acetate, and γ-[33P]ATP. After incubation for 40 minutes at room temperature, the reaction is stopped and 10 μL of the reaction solution is then spotted onto a P30 filtermat and washed 3 times for 5 minutes in 75 mmol/L phosphoric acid and once in methanol prior to scintillation counting.
Cell Assay:[1]
  • Cell lines

    HUVECs, L-02, B16-F10, HepG2, and SW620 cells.

  • Concentrations

    ~40 μM

  • Incubation Time

    24 hours

  • Method

    Cell proliferation is measured using MTT assay. Various cells including HUVECs, L-02, B16-F10, HepG2, and SW620 are treated with indicated concentrations of SKLB1002 for 24 hours. Vandetanib and sunitinib serve as positive controls. Each assay is replicated 3 times.
Animal Study:[1]
  • Animal Models

    Mice bearing SW620 or HepG2 tumors.

  • Dosages

    ~100 mg/kg daily

  • Administration

    i.p.
