Biological Activity

Description PF-573228 is an ATP-competitive inhibitor of FAK with IC50 of 4 nM in a cell-free assay, ~50- to 250-fold selective for FAK than Pyk2, CDK1/7 and GSK-3β. PF-573228 induces apoptosis.
Targets
FAK [1]
(Cell-free assay)
4 nM
In vitro PF 573228 blocks the phosphorylation of FAK Tyr397 in REF52 cells, PC3 cells, SKOV-3 cells, L3.6p1 and F-G, MDCK cells with IC50 of 30-500 nM. However, PF 573228 (1 μM) with 80% inhibition of FAK phosphorylation fails to inhibit cell growth or apoptosis. Similar treatment of cells with PF-228 resulted in inhibition of serum or FN-directed migration and decreased focal adhesion turnover. [1]
In vivo Inhibition of FAK by PF-573,228 in Ctrl-MT mice leads to a significant suppression of mammary tumorigenesis as well as lung metastasis. In contrast, treatment of MFCKO-MT mice with PF-573,228 did not affect the initiation of mammary tumors in these mice, as would be expected due to the absence of FAK in mammary epithelial cells of these mice [2].

Protocol (from reference)

Kinase Assay:

[1]
  • Affinity determination

    Purified activated FAK kinase domain (amino acids 410–689) is reacted with 50 μM ATP, and 10 μg/well of a random peptide polymer of Glu and Tyr (molar ratio of 4:1), poly(Glu/Tyr) in kinase buffer (50 mM HEPES, pH 7.5, 125 mM NaCl, 48 mM MgCl2) for 15 min. Phosphorylation of poly(Glu/Tyr) is challenged with serially diluted compounds at 1/2-Log concentrations starting at a top concentration of 1 μM. Each concentration is run in triplicate. Phosphorylation of poly(Glu/Tyr) is detected with a general anti-phospho-tyrosine (PY20) antibody, followed by horseradish peroxidase-conjugated goat anti-mouse IgG antibody. The standard horseradish peroxidase substrate 3, 3
Cell Assay:

[1]
  • Cell lines

    REF52 or PC3 cells

  • Concentrations

    ~10 μM

  • Incubation Time

    3 days

  • Method

    Growth assays are performed by seeding 1 × 104 REF52 or PC3 cells/well of a 24-well plate in triplicate 24 h prior to daily treatment with the indicated concentrations of each inhibitor for 3 days. Subsequently, the cells are harvested and counted.

[2]
  • Animal Models

    Ctrl-MT and MFCKO-MT mice

  • Dosages

    5 mg/kg

  • Administration

    oral administration
