Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

Targets/IC50/Ki
FAK [1]
(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. [1] This compound also promotes G0-G1 cell-cycle arrest followed by cell death in HEY and OVCAR8 cells. [2]
Kinase Assay
In vitro kinase activity
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. [1]
