Product Description

Description: PF-562271 is a novel, potent, ATP-competitive, orally bioavailable, reversible inhibitor of FAK (focal adhesion kinase) and Pyk2 catalytic activity with a IC50 of 1.5 and 14 nmol/L, respectively. it has >100-fold selectivity against other protein kinases. Additionally, PF-562,271 displayed robust inhibition in an inducible cell-based assay measuring phospho-FAK with an IC(50) of 5 nmol/L. PF-562,271 was evaluated against multiple kinases and displays >100x selectivity against a long list of nontarget kinases. PF-562,271 inhibits FAK phosphorylation in vivo in a dose-dependent fashion (calculated EC(50) of 93 ng/mL, total) after p.o. administration to tumor-bearing mice. In vivo inhibition of FAK phosphorylation (>50%) was sustained for >4 hours with a single p.o. dose of 33 mg/kg. Antitumor efficacy and regressions were observed in multiple human s.c. xenograft models. PF-562271 is a potential therapeutic agent either alone or in combination with other agents for the treatment of cancer.

Biological Activity I Assay Protocols (From Reference)
ln Vitro
In recombinant enzyme assays, PF-562271 (VS-6062) is demonstrated to be a 30- to 120-nM inhibitor of CDK2/E, CDK5/p35, CDK1/B, and CDK3/E. In cell-based assays assessing the function of CDKs, 3.3 μM PF-562271 must be exposed for 48 hours in order to modify cell cycle progression. With an IC50 of 5 nM, PF-562271 demonstrates potency in an inducible cell-based assay for detecting phospho-FAK. On cell growth and colony formation in Ewing sarcoma cell lines, PF-562271, a selective inhibitor of both FAK and proline-rich tyrosine kinase 2 (PYK2), a member of the FAK-related family, acts. Using 2-fold serial dilutions, seven cell lines are treated with PF-562271 for five days at various concentrations. After three days of treatment, PF-562271 therapy reduces cell viability in all cell lines, with an average IC50 of 2.4 μM. The two most sensitive cell lines are TC32 and A673, with IC50 values of 2.1 and 1.7 μM, respectively[2].
ln Vivo
Following po treatment to tumor-bearing animals, PF-562271 suppresses FAK phosphorylation in vivo in a dose-dependent manner (calculated EC50 of 93 ng/mL, total)[1]. After two weeks of treatment, rats given PF-562271 show a decrease in tumor development and indications of bone healing, as shown by the deposition of new bone (cortical and cancellous) at tumor-damaged sites[3].
Animal Protocol

Solubility (In Vivo)
Solubility in Formulation 1: ≥ 1.67 mg/mL (3.29 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 16.7 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL.
Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution.

Solubility in Formulation 2: ≥ 1.67 mg/mL (3.29 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 16.7 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.

 (Please use freshly prepared in vivo formulations for optimal results.)

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
