Name: Zotatifin
Brand: Selleck Chemicals
SKU: S8994
Rating: 5 (1 reviews)

Zotatifin (eFT226) is a highly effective and sequence-selective inhibitor of the RNA helicase eIF4A. It promotes eIF4A binding to specific mRNA sequences with recognition motifs in the 5'-UTRs, with an IC50 of 2 nM, and disrupts the assembly of the eIF4F initiation complex. By enhancing the interaction between eIF4A and polypurine RNA sequence or structural motifs, zotatifin converts eIF4A into a sequence-specific translation repressor, thereby regulating the translation of certain target genes. It also exhibits anti-tumor activity.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH₂O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
