Biological Activity

Description PND-1186 (VS-4718, SR-2156) is a reversible and selective FAK inhibitor with IC50 of 1.5 nM. PND-1186 selectively promotes tumor cell apoptosis. Phase 1.
FAK [1]
(Cell-free assay)
1.5 nM
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]

4T1 cells were seeded at 70% confluency on tissue culture plates coated with 10 µg/ml fibronectin. Cells were treated with vehicle (DMSO) or increasing PND-1186 addition for 1 h. Shown is total FAK, p130Cas, Src, or actin levels in cell lysates. Phospho-specific immunoblotting was performed in parallel for changes in FAK or Src activity (pY397 FAK or pY416 Src) and p130Cas tyrosine phosphorylation (pY249 p130Cas).

Immunofluorescence staining of STAT3 in MDA-MB 231 cells treated for 1 h with 100 nM E2 and 100 nM G1 alone or in combination with 1 μM FAK kinase inhibitor VS-4718. Cells were probed with rabbit anti-STAT3 primary antibody followed by FITC-conjugated secondary antibody in order to detect STAT3 displayed by the green signal, whereas the blue signal indicates the nuclei counterstained with DAPI. Images shown are representative of 10 random fields.

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]


Kinase Assay:


- Collapse

In vitro kinase activity:

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.
Cell Research:

  • Cell lines: Murine ID8 ovarian carcinoma cells
  • Concentrations: ~1 μM
  • Incubation Time: 6 days
  • 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.

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
