Product Description

4EGI-1 is a potent and competitive eIF4E/eIF4G interaction inhibitor which binds to eIF4E with KD of 25 μM. It has been demonstrated that 4EGI-1, through down-regulating FLIPS/L and inducing DR5, amplifies TRAIL (tumor necrosis factor-related apoptosis-inducing ligand)-induced apoptosis. These properties of the compound appear to be unrelated to its capacity to suppress cap-dependent protein translation, which is brought about by binding to eIF4E and disrupting the eIF4E/eIF4G association. Research has demonstrated that although 4EGI-1 separates eIF4G from eIF4E, it also strengthens the 4E-BP association in vitro and in vivo.

Biological Activity I Assay Protocols (From Reference)
Targets
eIF4E/eIF4G (Kd = 25 μM); mTOR
ln Vitro

4EGI-1 suppresses Cap-dependent translation by upsetting the eIF4F complex in vitro. With an IC50 of roughly 6 μM in A549 lung cancer cells, 4EGI-1 potently inhibits cell growth and exhibits proapoptotic activity in Jurkat cells. In human lung cancer cells, 4EGI-1 increases TRAIL-induced apoptosis without inhibiting cap-dependent protein translation by inducing DR5 and downregulating c-FLIP. Furthermore, in chronic lymphocytic leukemia, 4EGI-1, via both cap-dependent and -independent mechanisms, restores sensitivity to ABT-737 apoptosis.

ln Vivo
4EGI-1 (75 mg/kg, i.p.) suppresses the growth of tumors and tumorangiogenesis in breast cancer stem cells (CSCs) in vivo. 4EGI-1 (75 mg/kg, i.p.) inhibits the weight and volume of tumors in mice injected with U87 cells.
Cell Assay
For a duration of 24 hours, DMSO, [E]-4EGI-1, or [Z]-4EGI-1 at various concentrations are applied to 1 × 104 breast CSCs HMLER (CD44high/CD24low)FA cells and other indicated breast cancer cells. Cell viability assays are carried out on the cells using a cell viability assay kit. Three separate experiments are carried out. The mean ± SD, t-test, two-tailed, average IC50 results are displayed[2].
Animal Protocol
Mice: For the tumor xenografted assay, 100 μL of a Matrigel/DMEM mixture (Matrigel: DMEM = 1:2) is combined with 1×105 breast cancer stem cells (CSCs). Subcutaneous injections of breast CSCs, Matrigel, and DMEM mixtures are administered to the mammary glands of NOD/SCID female mice. Following the formation of the tumor, which grew to a volume of approximately 75 mm3 and affected 5 mice per group, the mice were given intraperitoneal injections of DMSO, 75 mg/kg [E]-4EGI-1, or 75 mg/kg [Z]-4EGI-1 every day for 30 days. Three-day intervals are used to measure tumor volumes. Mice are sacrificed on day thirty, and tumors are removed. Weights of tumors are quantified. Western blot, immunoprecipitation, and immunohistochemistry analyses are performed on tumor tissue samples[2].

Solubility Data
Solubility (In Vitro)
DMSO: ~90 mg/mL (~199.4 mM)

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 20% SBE-β-CD physiological saline solution and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution.

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

*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.

  • 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
