PF-573228(50毫克)产品是PF-573228 is a potent and selective inhibitor of focal adhesion kinase (FAK) (IC₅₀ = 4 nM). PF-573,228 inhibits FAK phosphorylation on Tyr(397) with an IC₅₀ of 30-100 nM. Displays 50 - 250-fold selectivity for FAK over other protein kinases. Blocks serum and fibronectin-directed migration and decreases focal adhesion turnover in vitro.
