Defactinib hydrochloride inhibits FAK phosphorylation at the Tyr397 site in a time- and dose-dependent manner, which may prevent the integrin-mediated activation of several downstream signal transduction pathways. RPPA data shows that VS-6063 reduces levels of AKT and YB-1 in taxane-resistant cell lines.
In vivo, Defactinib hcl doses of 25 mg/kg twice a day or greater statistically significantly inhibits pFAK (Tyr397) at 3 hours, with return of expression noted by 24 hours.
