FOXO4-DRI
Also known as: Proxofim, Senolytic Peptide
A senolytic peptide that selectively destroys senescent (zombie) cells by disrupting the FOXO4-p53 interaction that keeps them alive. The first peptide-based senolytic.
Mechanism of Action
Competes with endogenous FOXO4 for p53 binding. In senescent cells that depend on FOXO4-p53 interaction for survival, this releases p53 to the mitochondria to trigger apoptosis. Normal cells are unaffected.
Dosing Protocol
Research protocols: 5 mg/kg IV every 3 days for 3 doses in mouse studies. Human dosing not established.
Open peptide calculatorReconstitution
Research-grade: lyophilized, reconstitute in sterile water.
Storage
Lyophilized: -80°C preferred, -20°C acceptable. Very expensive compound.
Side Effects
- ●Limited human data
- ●Theoretical risk of affecting non-senescent cells at high doses
Key Research Findings
- ●Restored fitness, fur density, and renal function in aged mice (Cell 2017)
- ●Selectively killed senescent cells while sparing healthy cells
- ●First demonstration of peptide-based senolytic approach
