Solubility (25°C)* In vitro DMSO 83 mg/mL (199.29 mM)
Water Insoluble
Ethanol Insoluble
In vivo (Add solvents to the product individually and in order)
Clear solution
5% DMSO 95% Corn oil
0.51mg/ml Taking the 1 mL working solution as an example, add 50 μL of 10.2 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results. 
Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
4.15mg/ml Taking the 1 mL working solution as an example, add 50 μL of 83 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

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 (from reference)

Cell Assay:

[1]
  • 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.
Animal Study:

[1]
  • Animal Models

    C.B17 SCID female mice (6-8 weeks old)

  • Dosages

    50 mg/kg

  • Administration

    IP
