Description
Defactinib (VS-6063, PF-04554878) is a potent, selective and orally active FAK inhibitor, selectively inhibits pFAK (Tyr397) in a dose-dependent manner in cancer cell lines; shows no statistically significant changes in FAK phosphorylation at the other residues (Tyr 576/577, Tyr 925, or Tyr 861), also inhibits Pyk2 Tyr402 phosphorylation in HeyA8 cells; markedly decreases proliferation and increases apoptosis combined with paclitaxel, reduces levels of AKT and YB-1 in taxane-resistant cell lines; significantly reduces tumor growth, synergized with the mTOR inhibitor everolimus in xenograft models of pancreatic tumor.
