Background Information:
The cytoplasmic tyrosine kinase FAK (Focal Adhesion Kinase) is a signal transducer for integrins and is constitutively activated in various tumor cell types. It is involved in tumor cell invasion, migration and proliferation and plays a key role in the development, function and survival of cancer stem cells (CSCs). VS-4718 (PND-1186) is a potent, selective and orally bioavailable FAK inhibitor with IC50 at low nM range. It blocks fibronectin-stimulated FAK autophosphorylation of Tyr397, and prevents the integrin-mediated activation of several downstream signal transduction pathways, including ERK, JNK/MAPK and PI3K/Akt, resulting in the reduction of the number of cancer stem cells and inhibition of tumor cell migration, proliferation and survival. It displays strong anticancer activities both in vitro and in vivo, and is currently in clinical evaluation.
