FOX04-DRI (Retro-Inverso) is a synthetic variant of the FOXO4 protein designed to extend its half-life and inhibit normal FOXO4 function. Research shows it helps eliminate senescent cells, improve organ function, and reduce biological aging by interfering with FOXO4’s binding to p53.

H2: What Is FOXO4-DRI (Proxofim)?

FOXO4-DRI, also known as Proxofim, is a synthetic D-retro-inverso peptide derived from the FOXO4 transcription factor. It has gained attention in scientific research for its role in modulating cellular senescenceDNA damage response, and longevity signaling pathways.

By selectively targeting p53-FOXO4 interactions, FOXO4-DRI allows senescent cells to undergo apoptosis — a process essential in cellular rejuvenation and tissue regeneration studies.


Mechanism of Action

FOXO4-DRI mimics a sequence within the FOXO4 protein but in D-amino acid configuration, which resists enzymatic degradation.

In laboratory models, FOXO4-DRI works by:

  1. Disrupting FOXO4–p53 binding, allowing senescent cells to initiate apoptosis.

  2. Reducing pro-inflammatory cytokine secretion (SASP markers).

  3. Improving cellular resilience in aged or stressed tissues.

  4. Supporting mitochondrial balance and DNA repair processes.

This mechanism makes FOXO4-DRI a promising compound for studies on anti-aging, tissue rejuvenation, and degenerative disorders.
