Cell lines | Squamous carcinoma cells |
Preparation method | The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 ℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months. |
Reacting condition | 1 μM, 48 hr |
Applications | In squamous carcinoma cells, treatment of the FAK wt expressing cells with the FAK kinase inhibitor PF-562,271 resulted in a similar reduction in cell migration as seen in the FAK-/- cells. PF-562,271 dose-dependently inhibited FAK autophosphorylation on Y397. Treatment with PF-562,271 inhibited golgi orientation. PF-562,271 inhibited Pyk2 and Pyk2 autophosphorylation in PF-562,271 treated cells. Treatment of FAK wt cells with PF-562,271 dose-dependently inhibited cell proliferation. Treatment of FAK wt cells with PF-562,271 (0.25 μM) also resulted in a dose-dependent inhibition of colony formation. Treatment of cells with PF-562,271 in methylcellulose resulted in a small but significant reduction in the number of cells in S phase while the corresponding increase in G1 was not significant. |
Animal models | Mice bearing PC-3M, BT474, BxPc3, and LoVo tumors, |
Dosage form | Oral gavage, 25 to 50 mg/kg, twice daily |
Application | In several human s.c. xenograft models, PF-562271 dose-dependently inhibited tumor growth, and produced maximum tumor inhibition for PC-3M, BT474, BxPc3, and LoVo ranging from 78% to 94% inhibition at doses of 25 to 50 mg/kg twice daily, without weight loss, morbidity, or death. PF-562271 (25 mg/kg by p.o.) significantly decreased tumor progression in both subcutaneous and bone metastasis PC3M-luc-C6 xenograft models. |
Other notes | Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |
| 产品描述 | PF-562271 is a potent, ATP-competitive and reversible inhibitor of both focal adhesion kinase (FAK), a non-receptor tyrosine kinase involved in a variety of cellular events, and proline-rich tyrosine kinase 2 (Pyk2), an FAK homolog containing 48% amino acid identity, with half maximal inhibitory concentration (IC50) of 1.5 nmol/L and 14 nmol/L respectively. As a potential therapeutic agent either alone or in combination with other agents for the treatment of cancer, PF-562271 has been reported to effectively inhibit the proliferation of tumors in both xenograft and transgenic mouse models, in which it dose-dependently inhibits FAK phosphorylation in tumor-bearing mice with half maximal effective concentration (EC50) of 93 ng/mL.
