Description

PF-00562271 (PF-562271) is a potent ATP-competitive FAK and proline-rich tyrosine kinase (Pyk2) inhibitor with potential antineoplastic and antiangiogenic activities. Focal adhesion kinase (FAK) transduces signaling from integrins and growth factors to modulate tumor cell invasion, proliferation and survival. Focal adhesion kinase (FAK) is a non-receptor protein tyrosine kinase located in the cytoplasm at focal adhesions – sites that link the extracellular matrix to the cytoplasmic cytoskeleton. Not only do FAKs therefore play a pivotal role in cell migration, but they also influence cell survival and are upregulated in a broad spectrum of epithelial cancers. PF-00562271 (PF-562271) may inhibit tumor cell migration, proliferation, and survival. As FAK is a signal transducer for integrins, inhibition of FAK by PF-00562271 (PF-562271) may prevent integrin-mediated activation of several downstream signals including ERK, JNK/MAPK and PI3K/Akt. FAK and PYK2, upregulated in many tumor cell types, are involved in tumor cell invasion, migration and proliferation.
