Description
PF-573228 is an ATP-competitive inhibitor of with of 4 nM in a cell-free assay, ~50- to 250-fold selective for FAK than Pyk2, CDK1/7 and GSK-3β. PF-573228 induces .
PF 573228 blocks the phosphorylation of FAK Tyr in REF52 cells, PC3 cells, SKOV-3 cells, L3.6p1 and F-G, MDCK cells with IC50 of 30-500 nM. However, PF 573228 (1 μM) with 80% inhibition of FAK phosphorylation fails to inhibit cell growth or apoptosis. Similar treatment of cells with PF-228 resulted in inhibition of serum or FN-directed migration and decreased focal adhesion turnover.
In vivo
Inhibition of FAK by PF-573,228 in Ctrl-MT mice leads to a significant suppression of mammary tumorigenesis as well as lung metastasis. In contrast, treatment of MFCKO-MT mice with PF-573,228 did not affect the initiation of mammary tumors in these mice, as would be expected due to the absence of FAK in mammary epithelial cells of these mice .
