General description

A cell-permeable hydrazone compound that reversibly binds eukaryotic translation initiation factor 4E (eIF4E; KD = 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-xL in Jurkat cells (8 hrs), leading to apoptotic cell death after prolonged exposure (24 hrs, IC50 ~25 µM). Shown to be brain permeant and reduce neuroligin protein levels, and restore L-LTP threshold and rescue autistic-like behaviours in Eif4ebp2 knockout mice.

Biochem/physiol Actions

Cell permeable: yes
Primary Target
eIF4E
Reversible: yes

Packaging
