Product Description
Zotatifin (eFT226) is a potent, selective and well-tolerated inhibitor of eIF4A. Zotatifin can promote the binding of eIF4A to specific mRNA sequences with recognition motifs in 5'-UTRs (IC50=2 nM) and interfere with the assembly of the eIF4F initiation complex. Zotatifin displays potent antiviral effects by inhibiting SARS-CoV-2 NP protein biosynthesis, thereby effectively reducing viral infectivity (IC90=37 nM). Zotatifin causes apoptosis.
Biological Activity I Assay Protocols (From Reference)
ln Vitro
Zotatifin causes the stable ternary complex [eIF4A-RNA-eFT226] to form. In the presence or absence of eFT226, ozotifin lengthens the residence duration of eIF4A1 bound to the AGAGAG RNA surface, with Kd values of 0.021 μM and 8.0 μM [1]. has sequence-dependent inhibition of in vitro translation, with IC50 values in the MDA-MB-231 cell line of 1.5 nM, 13.8 nM, 92.5 nM, and 217.5 nM. temporarily transfected with 5'-UTRs for AGAGAG, GGCGGC, CCGCCG, and CAACAA. In a dose-dependent manner, zotatifin (0.0001 μM-1 μM; 72 hours) suppresses the development of tumor cells. It exhibits strong anti-apoptotic action in MDA-MB-231 tumor cells (GI50<15 nM). Zotatifin (0.0001 μM-1 μM; 72 hours) suppresses the proliferation of tumor cells against TMD8, SU-DHL-2, HBL1, Pfeiffer, and SU-DHL-; however, the anti-proliferative action of eFT226 is abruptly relieved by eIF4A1 F163L [1]. GI50 value 6, SU-DHL-10, VAL, Carnaval, U2973, Ramos, Jeko1, Mino, and Rec-1 cells have the following performance values: 4.1 nM, 3 nM, 5.6 nM, 3.7 nM, 5.3 nM, 7.3 nM, and 6.6 nM, in that order. The transformation regulatory protein of coconut genes is induced by zotatifin (30 μM-100 μM; 3 or 24 hours) in a dose- and time-dependent manner. Zotatifin's antiviral efficacy is evaluated using a number of certified tests, including the TCID50 assay, plaque assay, NP-staining assay, and others [2]. Less viral NP protein and less concentration were found in Vero E6 cells infected with SARS-CoV-2 isolates at concentrations of 100 nM, 200 nM, 500 nM, 2 μM, and 10 μM; 1 or 2 hours prior to virus isolation.
ln Vivo
In TMD8 xenografts, HBL1-bearing xenografts, Pfeiffer-bearing xenografts, and SU-DHL-6-bearing xenografts, zogafitin (IV; 1 mg/kg; 14–22 days) decreases tumor size and inhibits plaques. The percentages of tumor growth in SU-DHL-10 xenograft- and Ramos-bearing animals were 97%, 87%, 70%, 83%, 37%, and 75%, respectively [1]. In B-cell-localized xenograft models, zogafitin (IV; 0.001 mg/kg-1 mg/kg; 15 days) is well tolerated and reduces the growth of B-cell-localized xenografts [1].

*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 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
