Description

VS-4718 (PND-1186) is a reversible and selective FAK inhibitor with IC50 of 1.5 nM. PND-1186 selectively promotes tumor cell apoptosis. Phase 1.

Targets

FAK ^[1]
(Cell-free assay)

1.5 nM

In vitro
In vitro	In vitro, PND-1186 inhibits 4T1 breast carcinoma motility, promotes 4T1 apoptosis in suspended conditions, and decreases 4T1 soft agar colony number and size. ^[1] In HEY and OVCAR8 cells, VS-4718 promotes G0-G1 cell-cycle arrest followed by cell death. ^[2]
Kinase Assay	In vitro kinase activity
Kinase Assay	GST-FAK in vitro kinase activity is measured and compared 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 are determined with various concentrations of test compounds 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.

	Method	For soft agar assays, 48-well plates are coated with a 1:4 mix of 2% agar (EM Science) in 0.2 mL growth media (bottom layer). 5×10⁴ cells are plated per well (in triplicate) in a mixture of 0.3% agar in 0.2 mL growth media (top layer). After agar solidification, 0.2 mL growth media is added containing DMSO or PND-1186 (final concentration for 0.6 mL). In separate experiments, PND-1186 is added after 4 days. After 10 days, colonies are imaged in phase contrast, enumerated by counting 9 fields (3 fields per well), and total area determined using Image J. For all analyses, experimental points are performed in triplicate and repeated at least two times.

In Vivo
In vivo	In mice bearing 4T1 tumors, PND-1186 (100 mg/kg s.c.) inhibits 4T1 subcutaneous tumor growth by induction of apoptosis. In mice bearing ID8 tumors, PND-1186 (0.5 mg/mL for p.o.) also causes ovarian carcinoma tumor growth inhibition. ^[1]
