Abstract

In this issue of Chemistry & Biology, Arrendale and coworkers demonstrate a new prodrug strategy for intracellular delivery of an α, α-(difluoromethylene)phosphonate phosphoserine mimic. The deprotected pseudo-phosphopeptide releases the pro-apoptotic FOXO3a-transcription factor from its 14-3-3-adaptor protein complex, resulting in leukemic cell death.
