Biochem/physiol Actions

PF-431396 hydrate is a potent PYK2/FAK inhibitor
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.

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 .

In many cancers, a stem-like cell subpopulation mediates tumor initiation, dissemination and drug resistance. Here, we report that cancer stem cell (CSC) abundance is transcriptionally regulated by C-terminally phosphorylated p27 (p27pT157pT198). Mechanistically, this arises through p27 co-recruitment with STAT3/CBP to
