Description

FAK-IN-2 is a potent and orally active focal adhesion kinase (FAK) inhibitor, with anticancer activity (FAK IC50= 35 nM). FAK-IN-2 covalently inhibits the autophosphorylation of FAK in a dose-dependent manner, and inhibits the clone formation and migration of tumor cells, inducing apoptosis[1].

IC50 & Target

IC50: 35 nM (FAK)[1]
In Vitro

FAK-IN-2 (compound 11w) (0-5 μM; 72 hours) has high anti-proliferation activities on cancer cell lines, as well as certain toxicity on normal cell lines[1].
FAK-IN-2 (0-30 nM; 14 days) can remarkably affect HCT-116 cells clone formation in a dose-dependent manner[1].
FAK-IN-2 (10-500 nM; 24 and 48 hours) significantly inhibits the migration of HCT116 cells at both 24 h and 48 h in a dose-dependent manner[1].
FAK-IN-2 (0.001-10 μM; 4 and 24 hours) inhibits the phosphorylation of FAK and its downstream proteins from multiple pathways[1].
FAK-IN-2 (0.01-1 μM; 24 or 48 hours) induces strong cell cycle arrest at the G2/M phase and apoptosis[1].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: 2.5 mg/mL (4.44 mM); Clear solution; Need ultrasonic

    This protocol yields a clear solution of 2.5 mg/mL.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: 2.5 mg/mL (4.44 mM); Clear solution; Need ultrasonic

    This protocol yields a clear solution of 2.5 mg/mL.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
