Beschreibung

Allgemeine Beschreibung

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 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.
