Biological target: PF-573228 is a potent and selective FAK inhibitor with IC50 of 4 nM (FAK).
In vitro activity: In the present study, the pharmacological effect of PF-573228 on inhibiting FAK activity and limiting lung cancer cell growth was tested. Given the role of FAK signaling in tumor growth and metastasis, it was hypothesized that inhibiting the catalytic activity of FAK may disrupt FAK signaling and blunt tumor cell proliferation. Therefore, three distinct non-small cell lung cancer cell lines (A549 lung adenocarcinoma cells and H460 and H1299 large cell carcinoma cells) were treated with PF-573228, an enzymatic inhibitor of FAK. PF-573228 was administered to the lung cancer cells for 4 days at three doses: 0.1, 1, or 10 μM. The growth curves showed that 10 μM PF-573228 effectively induced cessation of cell growth (Figures 1A–C). When lung cancer cells were treated with PF-573228, an abnormal nuclear shape was observed. Furthermore, it was found that PF-573228 treatment does not dramatically affect nuclear translocation of FAK in A549 cells. This implied that FAK-mediated signaling to maintain lamin A/C expression may not be through transcriptional regulation.

In vivo activity: To better understand the role of FAK in leukocyte recruitment, a FAK-specific inhibitor (PF-573228) was used and determined the effect on IL-4 induced eosinophil recruitment in vitro and in vivo. PF-572338 also prevented IL-4-induced VCAM-1 expression in vivo. Using brightfield intravital microscopy, it was found that PF-573228 decreased leukocyte rolling flux, adhesion, and emigration. Eosinophil recruitment was examined in vivo by using an eosinophil-GFP reporter mouse and found PF-573228 attenuated eosinophil emigration. This study reveals that a FAK inhibitor influences inflammation through its action on eosinophil recruitment.
