Product Description
FDI-6 is a FOXM1 inhibitor. In MCF-7 breast cancer/tumor cells, FDI-6 directly binds to the FOXM1 protein, displaces FOXM1 from the target genome, and induces subsequent transcriptional downregulation.
Biological Activity I Assay Protocols (From Reference)
ln Vitro
After extensive analysis, it is demonstrated that FDI-6 binds directly to the FOXM1 protein in MCF-7 breast cancer cells, displacing it from its genetic sites and causing hydrolysis as a result. After three hours of FDI-6 treatment, MDA-MB-231 ER breast cancer and PEO-1 breast cancer show significant modulation of CDC25B. Both types of breast cancer are susceptible to FDI-6 in cell viability (GI50=21.8 μM and 18.1 μM, respectively). of. These genes are networked and essential for G2/M transition, chromosomal segregation, and mitotic spindle integration; their absence triggers the cell killer cycle. Significantly, it has been demonstrated that abnormal overexpression of FOXM1 is a major role in the course of cancer and has been suggested as the initial cause of carcinogenesis [1].

Solubility Data
Solubility (In Vitro)
DMSO : ~41.67 mg/mL (~95.26 mM)
Solubility (In Vivo)
Solubility in Formulation 1: 2.5 mg/mL (5.72 mM) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), suspension solution; with sonication.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL.
Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution.

Solubility in Formulation 2: ≥ 2.5 mg/mL (5.72 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.

 (Please use freshly prepared in vivo formulations for optimal results.)

1 mM 2.2861 mL 11.4304 mL 22.8608 mL
5 mM 0.4572 mL 2.2861 mL 4.5722 mL
10 mM 0.2286 mL 1.1430 mL 2.2861 mL

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box

Biological Data
  • EMSA provides orthogonal biophysical validation of 16 lead compounds from FP screen (a) Representative EMSA image shows the association of FOXM1 DBD with its fluorescently tagged DNA consensus. Binding curve for the FOXM1 DBD-DNA interaction was determined by quantification of EMSA replicates. (b) Quantification of EMSA bands confirmed six of the 20 lead compounds selected from the FP results inhibited FOXM1 DNA binding. In rank order of potencies: FDI-6 >FDI-10 > FDI-11 > FDI-4 > FDI-2 > FDI-7. Representative gel images are provided in Supplementary concentrations in MCF-7 cells. (c) Representative Fig. 5.

  • Compound FDI-6 shows promising FOXM1-specific inhibitory effects in MCF-7 cells (a) FDI compounds were investigated for direct interaction with FOXM1 protein by nondenaturing nanoESI MS. EMSA validated hits FDI-6 (yellow stars), FDI-10 (green stars), and FDI-11 (purple stars) associate with the protein in a 1:1 stoichiometric ratio. Negative control FDI-9 was identified as a false positive by EMSA and does not associate with the protein. Mass shifts indicating ligand association are indicated by red arrows. (b) Western blots on the whole cell and chromatin fractions revealed a specific displacement of DNA bound FOXM1 while total levels were unaffected. Total MCF-7 cell lysate and chromatin bound fractions were isolated after 6 h treatment with FDI-6 or DMSO control. (c) Quantification of western blots revealed displacement of FOXM1 from DNA. Data were normalized to Actin (total lysate) and Histone H3 (chromatin fraction). (d) Targeted ChIP PCR revealed 6 h treatment with FDI-6 decreased FOXM1 occupancy at known FOXM1 target genes. Refer to legend for c-d. Data are reported as average of replicates (n=3) and error bars indicate s.d. throughout the figure.
