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.

Biological Activity

Description PF-562271 HCl, the hydrochloride salt of PF-562271, is a potent, ATP-competitive, reversible inhibitor of FAK with IC50 of 1.5 nM, ~10-fold less potent for Pyk2 than FAK and >100-fold selectivity against other protein kinases, except for some CDKs.
Targets FAK Pyk2        
IC50 1.5 nM 14 nM
