Description

General description

A cell-permeable hydrazone compound that reversibly binds eukaryotic translation initiation factor 4E (eIF4E; K_D = 25 µM) and disrupts eIF4E/eIF4G, but not eIF4E/4E-BP1, complex formation. Reported to downregulate the protein, but not mRNA, levels of c-Myc and Bcl-x_L in Jurkat cells (8 h), leading to apoptotic cell death after prolonged exposure (24 h, IC₅₀ = ~ 25 µM). Also available as a 25 mM solution in DMSO (Cat. No. 324519).
