Biological Activity

Description Icotinib (BPI-2009H) is a potent and specific EGFR inhibitor with IC50 of 5 nM, including the EGFR, EGFR(L858R), EGFR(L861Q), EGFR(T790M) and EGFR(T790M, L858R).
Targets
EGFR [1]
5 nM
In vitro Icotinib inhibits EGFR activity in a dose-dependent manner, with an IC50 value of 5 nM and complete inhibition at 62.5 nM. Icotinib selectively solely inhibits the EGFR members including the wild type and mutants with inhibition efficacies of 61-99%. Icotinib blocks EGFR-mediated intracellular tyrosine phosphorylation in human epidermoid carcinoma A431 cells in a dose-dependent manner. Meanwhile, in our proliferation assay performed on A431, BGC-823, A549, H460, HCT8, KB and Bel-7402 cell lines, we found that the relative sensitivity of cell lines to Icotinib is A431 > BGC-823 > A549 > H460 > KB > HCT8 and Bel-7402. Icotinib exhibits a broad spectrum of antitumor activity and it is especially effective against tumors expressing higher levels of EGFR. [1]
In vivo Icotinib shows an antitumor effect in different types of xenografts. Icotinib inhibits tumor growth at a rate of 51.5%, 31.0% and 67.4% in the A431, A549 and H460 xenografts at a dose of 120 mg/kg, respectively. [1]

Protocol (from reference)

Kinase Assay:[1]
  • Biochemical kinase assays

    In the in vitro kinase assays, 2.4 ng/μL EGFR protein is mixed with 32 ng/μL Crk in 25 μL kinase reaction buffer containing 1 μM cold ATP and 1 μCi 32P-γ-ATP. The mix is incubated with Icotinib at 0, 0.5, 2.5, 12.5 or 62.5 nM on ice for 10 min followed by incubation at 30 °C for 20 min. After quenching with SDS sample buffer at 100 °C for 4 min, the protein mix is resolved by electrophoresis in a 10% SDS-PAGE gel. The dried gel is then exposed to the PhosphorImager to detect radioactivity. Quantification is performed by ImageQuant software. In this methodology the radioactive signal inversely correlates with kinase activity.
Cell Assay:[1]
  • Cell lines

    A431, BGC-823, A549, H460, HCT8, KB and Bel-7402 cells.

  • Concentrations

    ~25 μM

  • Incubation Time

    96 h

  • Method

    Cells (103 /well) are seeded into 96-well plates in RPMI-1640 medium containing 10% FBS and grown in a 5% CO2 incubator at 37 °C. After 24 h, cells are treated with Icotinib at 0, 0.78, 1.56, 3.125, 6.25, 12.5 or 25 μM for 96 h. Cell proliferation is calculated by subtracting the mean absorbance value on day 0 from the mean absorbance value on day 4.
Animal Study:[1]
  • Animal Models

    A431, A549, H460 and HCT8 xenografts Nude mice

  • Dosages

    30, 60 and 120 mg/kg/day

  • Administration
