Second-Generation Cap Analogue Prodrugs for Targeting Aberrant Eukaryotic Translation Initiation Factor 4E Activity in Cancer.

ABSTRACT: Dysregulation of translation is a hallmark of cancer that enables rapid changes in cellular protein production to shape oncogenic phenotypes. Translation initiation is governed by the m⁷GpppX cap-binding protein eukaryotic translation initiation factor 4E (eIF4E), the rate-limiting factor of cap-dependent translation initiation. eIF4E is overexpressed in many cancers and drives the production of oncoproteins that promote tumor growth and survival. Accordingly, eIF4E has been established as an attractive albeit challenging therapeutic target. Building upon our previous work of developing cell-permeable cap analogue prodrugs that inhibit eIF4E binding to the m⁷GpppX cap, herein we disclose the design of second-generation cap analogues with alternative N-9-substit
