FOXO4-DRI

The first rationally designed senolytic peptide that selectively eliminates senescent cells by disrupting FOXO4-p53 interaction.

Also known as: Senolytic Peptide, D-Retro-Inverso

IntravenousSubcutaneous (experimental)

How It Works

D-retro-inverso peptide that penetrates cells and disrupts FOXO4-p53 protein interaction. Releases p53 from nuclear sequestration, leading to mitochondrial translocation and senescent cell-specific apoptosis.

Key Benefits

  • Selective senescent cell elimination
  • Reduced SASP inflammatory cytokines
  • Improved tissue homeostasis (preclinical)
  • Potential restoration of age-related function
  • No off-target toxicity to healthy cells (animal data)

Key Takeaway

Remove the cellular zombies: FOXO4-DRI selectively triggers apoptosis in senescent cells for tissue rejuvenation.
