Biological Activity

Description Imatinib (STI571) is a multi-target inhibitor of tyrosine kinase with inhibition for v-Abl, c-Kit and PDGFR, IC50 values are 0.6 μM, 0.1 μM and 0.1 μM in cell-free or cell-based assays, respectively.

(M-07e cells)
v-Abl [1]
(Cell-free assay)
100 nM 100 nM 600 nM
In vitro

In vitro assays for inhibition of a panel of tyrosine and serine/threonine protein kinases show that Imatinib inhibits the v-Abl tyrosine kinase and PDGFR potently with an IC50 of 0.6 and 0.1 μM, respectively. [1] Imatinib inhibits the SLF-dependent activation of wild-type c-kit kinase activity with a IC50 for these effects of approximately 0.1 μM, which is similar to the concentration required for inhibition of PDGFR. [2] Imatinib exhibits growth-inhibitory activity on the human bronchial carcinoid cell line NCI-H727 and the human pancreatic carcinoid cell line BON-1 with an IC50 of 32.4 and 32.8 μM, respectively. [3] A recent study shows that Imatinib has the potential to exert its antileukemia effects in chronic myelogenous leukemia by down-regulating hERG1 K(+) channels, which are highly expressed in leukemia cells and appear of exceptional importance in favoring leukemogenesis.

In vivo Imatinib produces a different antitumor effect on three xenografted tumors derived from surgical samples of fresh human small cell lung cancers, with 80%, 40% and 78% growth inhibition of SCLC6, SCLC61 and SCLC108 tumors, respectively, and no significant inhibition of SCLC74 growth. [5] In high fat fed ApoE(-/-) mice, Imatinib significantly reduces the high fat-induced lipid staining area by 30%, 27% and 35% compared to high-fat diet untreated controls when dosed by gavage at 10, 20 and 40 mg/kg, respectively, and suppresses carotid artery lipid accumulation.

PDGF receptor kinase activity:

PDGF receptor is immunoprecipitated from BALB/c 3T3 cell extracts with rabbit antiserum to the murine PDGF receptor for 2 hours on ice. Protein A-Sepharose beads are used to collect the antigen-antibody complexes. The immunoprecipitates are washed twice with TNET (50 mM Tris, pH 7.5, 140 mM NaCl, 5 mM EDTA, 1% Triton X-100), once with TNE (50 mM Tris, pH 7.5, 140 mM EDTA), and once with kinase buffer (20 mM Tris, pH 7.5,10 mM MgCl2). After stimulation with PDGF (50 ng/mL) for 10 minutes at 4 °C, different concentrations of drug are added to the reaction mixture. PDGF receptor kinase activity is determined by incubation with 10 μCi [7-33P]-ATP and l μM ATP for 10 minutes at 4 °C. Immune complexes are separated by SDS-PAGE on 7.5% gels.

  • Cell lines: BON-1 cells and NCI-H727 cells
  • Concentrations: ~100 μM
  • Incubation Time: 48 hours
  • Method:

    BON-1 cells and NCI-H727 cells are seeded into flat-bottomed 96-well plates in triplicate and allowed to adhere overnight in 10% fetal bovine serum-supplemented DMEM or RPMI 1640 complete medium, respectively; the medium is then exchanged for serum-free medium (negative control) or serum-free medium containing serial dilutions of Imatinib. After 48 hours (control cultures do not reach confluence), the number of metabolically active cells is determined by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, and absorbance is measured in a Packard Spectra microplate reader at 540 nm. Growth inhibition is calculated using the following formula: inhibition rate = (1 − a / b) × 100%, where a and b are the absorbance values of the treated and control groups, respectively.

Frequently Asked Questions

  • Question 1:

    Could you please advise whether it is a clear solution for compound dissolved in vehicle 2% DMSO+30% PEG 300+2% Tween 80+ddH2O?

  • Answer:

    For S2475 Imatinib (STI571), it is soluble in 2% DMSO+30% PEG 300+2% Tween 80+ddH2O at 2mg/ml. When making the solution, please dissolve the compound in DMSO clearly first. If it dissolves not readily, please sonicate and warm it in water bath at 45-50C. Then add PEG and Tween. After they mixed well, dilute with water.

  • Question 2:

    What is the difference between S2475 (Imatinib) and S1026 (Imatinib Mesylate)? Are they water soluble?

  • Answer:

    S2475 is free base of Imatinib while S1026 is a solt form of Imatinib. They have exactly the same biological activity but different solubility. S1026 can be dissolved in water, but S2475 is not soluble in water. S2475 can be dissolved in DMSO at up to 3mg/ml.
