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.
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]

cyclin B1; 

PubMed: 30761269     


(D) On the third day, PF-573228-treated cells were harvested and subjected to Western blot analysis for cyclin B1. Cyclin B1 levels were much higher in A549 cells with 1 μM PF-573228 or without PF-573228 treatment than in the cells treated with higher concentrations of PF-573228. (E) After 10 μM PF-573228 treatment, cyclin B1 levels declined markedly in H460 cells. (F) PF-573228 administration slightly reduced cyclin B1 levels in H1299 cells. 

p-FAK / FAK ; 

PubMed: 30761269     


FAK expression levels and FAK activity, as measured by the phosphorylation of FAK at tyrosine 576 and 577, were quantified by Western blot analysis after treatment of lung cancer cells with PF-573228 for 3 days.

Lamin A / Lamin C; 

PubMed: 30761269     


(B) The cells treated with 10 μM PF-573228 exhibited a decrease in p-FAK levels. Lamin A and lamin C expression levels were much lower in A549 cells exposed to 10 μM PF-573228. 

30761269
Immunofluorescence
FAK / F-actin; 

PubMed: 30761269     


(B) The cells were stained with phalloidin to visualize F-actin (red) and a FAK antibody to visualize the FAK distribution (green). In cells without PF-573228 administration, FAK translocated to focal adhesions at the tips of actin stress fibers, and the focal adhesions were relatively large. When cells were exposed to 10 μM PF-573228, FAK translocation to focal adhesions was reduced, and the sizes of the focal adhesions were smaller. Nuclei in cells treated with PF-573228 were deformed, as visualized with DAPI staining, whereas most nuclei in cells without PF-573228 treatment were oval shaped. 

Emerin; 

PubMed: 30761269     


(A) After PF-573228 treatment of A549 cells, the cells were fixed and stained with phalloidin to label F-actin (red) and an antibody against emerin (green) to outline the nuclear shape. Cells treated with PF-573228 were extremely large and had deformed nuclei, whereas mostly oval-like nuclei were present in the cells without PF-573228 treatment.

Cell viability; 

PubMed: 30761269     


Three different types of lung cancer cells, (A) A549 lung adenocarcinoma and (B) H460, and (C) H1299 large cell carcinoma, were selected for the PF-573228 administration regimen. Cell growth curves of the three lung cancer cell lines treated with various doses of PF-573228 for 4 days were established. The administration of PF-573228 at 10 μM to the lung cancer cells effectively suppressed cell growth in vitro, as proliferative activity totally ceased in the cells exposed to 10 μM PF-573228.

30761269
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].

- Collapse

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
