Imatinib (STI571) is an orally bioavailable tyrosine kinases inhibitor that selectively inhibits BCR/ABL, v-Abl, PDGFR and c-kit kinase activity. Imatinib (STI571) works by binding close to the ATP binding site, locking it in a closed or self-inhibited conformation, therefore inhibiting the enzyme activity of the protein semicompetitively. Imatinib also is an inhibitor of SARS-CoV and MERS-CoV.

    Description

    Imatinib (STI571) is an orally bioavailable tyrosine kinases inhibitor that selectively inhibits BCR/ABL, v-Abl, PDGFR and c-kit kinase activity. Imatinib (STI571) works by binding close to the ATP binding site, locking it in a closed or self-inhibited conformation, therefore inhibiting the enzyme activity of the protein semicompetitively[1][2][3][4]. Imatinib also is an inhibitor of SARS-CoV and MERS-CoV[5].

    IC50 & Target

    BCR/ABL, v-Abl, PDGFR, c-kit[1][2][4]
    In Vitro

    Imatinib (STI571) inhibits c-Kit autophosphorylation, activation of MAPK, and activation of Akt without altering total protein levels of c-kit, MAPK, or Akt. The concentration that produces 50% inhibition for these effects is approximately 100 nM[1].
    Imatinib (STI571) is very effective (in vitro IC50 of 25 nM) against the chronic myeloid leukemia-causing kinase Bcr-Abl. Imatinib also efficiently inhibits Kit (in vitro IC50, 410 nM) and PDGFR (in vitro IC50, 380 nM)[2].
    Imatinib (STI571) is a multi-target inhibitor of v-Abl, c-Kit and inhibits Bcr/Abl, v-Abl, Tel/Abl, the native PDGFβ receptor, and c-Kit, but it does not inhibit Src family kinases, c-Fms, Flt3, the EGFR or multiple other tyrosine kinases. Imatinib inhibits tyrosine phosphorylation and cell growth of Ba/F3 cells expressing Bcr/Abl, Tel/Abl, Tel/PDGFβR, and Tel/Arg with an IC50 of approximately 0.5 μM in each case, but it has no effect on untransformed Ba/F3 cells growing in IL-3 or on Ba/F3 cells transformed by Tel/JAK2[4].
    The IC50s of Imatinib(STI571) is a multi-target inhibitor of v-Abl, c-Kit and on BON-1 and H727 cells after exposure for 48 h are 32.4 and 32.8 μM, respectively[6].

    [4]

    BON-1 cells (7,500 per well) and NCI-H727 cells (5,000 per well) 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 h (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. Experiments are done in triplicates[4].

    Animal Administration
    [6][7]

    Mice[6]
    The 40 tumor-bearing SCID mice are randomly divided into four groups (10 mice per group): the PS-ASODN group (5 μM, each mouse receives 0.2 mL by intratumor injection once daily); Imatinib group (0.1 mg/g body weight); liposome negative control group (0.01 mL/g); and saline group (0.01 mL/g). The mice in each group receive the relevant treatment by intra-tumor injection once daily from day 7 to day 28 after implantation. After 28 d, the mice are sacrificed, and tumor weight and longest and shortest diameters are measured by electronic scale and vernier caliper, respectively. Inhibition of tumor growth is calculated.
    Rats[7]
    Adult female Wistar-Albino rats (220-240 g) are used. Twenty-one days after the first surgical procedure, the rats undergo a second laparotomy to evaluate the occurrence of endometriosis. Twenty-four rats have visually confirmed endometriotic implants and are randomized into three groups to receive Imatinib (25 mg/kg/day, p.o.), Anastrozole (0.004 mg/day, p.o.), or normal saline (0.1 mL, i.p.) for 14 days.

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
