SynonymseIF4E/eIF4G interaction inhibitor II.
ProtocolIn Vitro4E1RCat is an inhibitor of eIF4E:eIF4GI interaction, with an IC50 an of ∼4 μM. 4E1RCat binding to eIF4E also interferes with eIF4G and 4E-BP binding. 4E1RCat inhibits ribosome recruitment to mRNA in a cap-dependent manner.
In Vivo4E1RCat (15 mg/kg, i.p.) affacts chemosensitivity of Pten+/-Eμ-Myc tumors in mice. 4E1RCat (15 mg/kg, i.p.) sensitizes Pten+/-Eμ-Myc and Tsc2+/-Eμ-Myc lymphomas to the cytotoxic effects of doxorubicin (Dxr), and 4E1RCat targets translation in mice.

Method for preparing DMSO master liquid: mg drug pre-dissolved in µL DMSO(Master liquid concentration mg/mL) ,Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation: Take µL DMSO master liquid, next add µL PEG300, mix and clarify, next add µL Tween 80,mix and clarify, next add µL ddH2O,mix and clarify.
Note:
  • (1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
  • (2) Be sure to add the solvent(s) in order.
