Application

PF-431396 hydrate has been used as a dual inhibitor of proline-rich tyrosine kinase 2 (PYK2) / focal adhesion kinase (FAK) inhibitor to study its effects on phosphorylation of Yes-associated protein (YAP) at Ser127 and steady state of transcriptional coactivator with PDZ-binding motif (TAZ) . It has also been used as a PYK2/FAK inhibitor to study its effects on protein kinase A activation in human sperm samples .

Biochem/physiol Actions

PF-431396 is a potent inhibitor of PYK2 and FAK kinases (IC50 = 11 and 1.5 nM, respectively). PF-431396 increases bone formation and protects against bone loss in ovariectomized rats.
