Biological Activity

Description EN4, a covalent ligand that targets cysteine 171 (C171) of MYC, is selective for c-MYC over N-MYC and L-MYC. EN4 inhibits MYC transcriptional activity, downregulates MYC targets, and impairs tumorigenesis.
Targets
MYC [1]
()
In vitro

EN4 directly targets MYC in cells, reduces MYC and MAX thermal stability, inhibits MYC transcriptional activity, downregulates multiple MYC transcriptional targets, and impairs tumorigenesis. EN4 treatment significantly impairs 231MFP breast cancer cell proliferation in a dose- and time-dependent manner. EN4 impairs the cell survival of MYC transformed mammary epithelial MCF10A cells, but not parental MCF10A cells that are not dependent on MYC.[1]

In vivo

EN4 treatment initiated after establishment of a 231MFP breast tumor xenograft in immune-deficient mice also significantly attenuates tumor growth in vivo.[1]

Protocol

Cell Research:

[1]

- Collapse
  • Cell lines: 231MFP, MDA-MB-231, HEK293T and MCF10A cells
  • Concentrations: 50 μM
  • Incubation Time: 24 h
  • Method:

    231MFP cells are seeded into 6 cm dishes and cells are treated with DMSO vehicle or EN4 (50 μM) for 24 h. Cells are harvested by scraping and RNA is isolated using Qiagen RNeasy mini kit with Qiagen DNase max kit to remove any DNA contamination. mRNA is enriched for using Oligo dT beads from the KAPA mRNA Capture Kit.

- Collapse
  • Animal Models: C.B17 SCID female mice (6-8 weeks old)
  • Dosages: 50 mg/kg
  • Administration: IP

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)

*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 )

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.
