Mechanism of Action

Targets/IC₅₀/Ki	FAK (Cell-free assay) 1.5 nM
In vitro	In vitro, VS-4718 (PND-1186) inhibits 4T1 breast carcinoma motility, promotes 4T1 apoptosis in suspended conditions, and decreases 4T1 soft agar colony number and size. This compound also promotes G0-G1 cell-cycle arrest followed by cell death in HEY and OVCAR8 cells.
Kinase Assay	In vitro kinase activity
Kinase Assay	VS-4718 (PND-1186) is evaluated by measuring GST-FAK in vitro kinase activity and comparing it to His-tagged FAK 411–686 using the K-LISA screening kit and poly(Glu:Tyr) (4:1) copolymer as a substrate immobilized on microtiter plates. IC50 values for this compound are determined with various concentrations in a buffer containing 50 µM ATP and 10 mM MnCl₂, 50 mM HEPES (pH 7.5), 25 mM NaCl, 0.01% BSA, and 0.1 mM Na orthovanadate for 5 min at room temperature. Serial diluted compounds are tested in triplicate. Substrate phosphorylation is measured using horseradish peroxidase-conjugated anti-pTyr antibodies with spetrophotometric color quantitation. IC50 values are determined using the Hill-Slope Model. Kinase selectivity profiling is performed by using the KinaseProfiler service.
In vivo	In mice bearing 4T1 tumors, VS-4718 (PND-1186) (100 mg/kg s.c.) inhibits subcutaneous tumor growth by induction of apoptosis. This compound (0.5 mg/mL for p.o.) also causes ovarian carcinoma tumor growth inhibition in mice bearing ID8 tumors.
