Biological Activity

[Description]:

PF-562271 (besylate) is a potent, ATP-competitive, reversible inhibitor of FAK and Pyk2 kinase with IC50 of 1.5 nM and 13 nM, and has > 100-fold selectivity against other protein kinases, except for some CDKs.

[Target]

IC50: 1.5 nM (FAK), 13 nM (Pyk2)

[In Vitro]

PF-562,271 is a 30- to 120-nM (15.2 to 60.1 ng/mL) inhibitor of cdk2/E, cdk5/p35, cdk1/B, and cdk3/E in recombinant enzyme assays[1]. PF-562,271 blocks bFGF-stimulated blood vessel angiogenesis as performed in chicken chorioallantoic membrane assays[2]. Treatment of cells with PF-562,271 or knock-down of FAK by siRNA is observed to increase cell-cell adhesion strength[3].

[In Vivo]

PF-562,271 (33 mg/kg, p.o.) inhibits FAK phosphorylation in tumors in a dose- and time-dependent manner in tumor-bearing mice. FAK phosphorylation inhibition relative to total blood concentration of PF-562,271 results in a calculated EC50 of 93 ng/mL. PF-562,271 (25 mg/kg, p.o.) induces apoptosis 2-fold greater in treated tumors compared with vehicle-treated control tumors on day 3[1]. PF-562,271 (33 mg/kg, p.o.) and dasatinib extensively inhibit the movement of tumor cells in the animals. Inhibition of FAK kinase activity following treatment with PF-562,271 results in altered E-cadherin dynamics in vivo[3].

[Kinase Assay]

Briefly, purified-activated FAK kinase domain (amino acid 410-689) is reacted with 50 μM ATP and 10 μg per well of a random peptide polymer of Glu and Tyr, p(Glu/Tyr), in kinase buffer [50 mM HEPES (pH 7.5), 125 mM NaCl, and 48 mM MgCl2] for 15 min. Phosphorylation of p(Glu/Tyr) is challenged with serially diluted compound at 1/2-Log concentrations starting at a top concentration of 1 μM. Each concentration is tested in triplicate. Phosphorylation of p(Glu/Tyr) is detected with a general antiphospho-tyrosine (PY20) antibody followed by horseradish peroxidase (HRP)-conjugated goat anti-mouse IgG antibody. HRP substrate is added, and absorbance readings at 450 nm are obtained after addition of stop solution (2mol/LH2SO4). IC50 values are determined using the Hill-Slope Model.

[Animal admin]

Exponentially growing cells are trypsinized and resuspended in sterile PBS and inoculated s.c. (1×106 cells per mouse in 200 μL) into the right flank of mice. Animals bearing tumors of appr 150 mm3 in size are divided into groups receiving either vehicle (5% Gelucire) or PF-562,271 (diluted in vehicle), and dosed by p.o. gavage. Animal body weight and tumor measurements are obtained every 2 d. Tumor volume (mm3) is measured with Vernier calipers and calculated. For all tumor growth inhibition experiments, 8 to 10 mice per dose group are used.
