Biological Activity

Description FDI-6 (NCGC00099374) is an inhibitor of the Forkhead box protein M1 transcription factor (FOXM1) with IC50 of 22.5 μM.
FOXM1 [1]
(Cell-free assay)
22.5 μM
In vitro

FDI-6 (NCGC00099374) is characterized in depth and is shown to bind directly to FOXM1 protein, to displace FOXM1 from genomic targets in MCF-7 breast cancer cells, and induces concomitant transcriptional down-regulation. Global transcript profiling of MCF-7 cells by RNA-seq shows that FDI-6 specifically down-regulates FOXM1-activated genes with FOXM1 occupancy confirmed by ChIP-seq.[1]

In vivo

Inhibiting FOXM1 with FDI-6 inhibits liver cancer cell growth in vivo.[2]


Cell Research:


- Collapse
  • Cell lines: MCF-7 cells
  • Concentrations: 20 μM, 40 μM
  • Incubation Time: 6 h
  • Method:

    MCF-7 cells are grown in 15 cm2 dishes to 70% confluence prior to FDI-6 or DMSO control treatment for 6h. Cells are washed with PBS, cross-linked with 1% formaldehyde at RT for 10 min and quenched with 1/20 volume glycine (2.5 M). Cells are harvested by scraping into cold PBS containing protease inhibitors and cell pellets stored at −80 ℃.

Bio Calculators

Molarity Calculator

Molarity Calculator

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:

Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)

  • Mass
    Molecular Weight

*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and SDS / COA (available on product pages).

Dilution Calculator

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration (start) x Volume (start) = Concentration (final) x Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

  • C1

* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and SDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:

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.
