FOX04-DRI (10mg) — Research Compound
FOXO4-DRI is a synthetic peptide designed to disrupt the interaction between the FOXO4 transcription factor and p53, a pathway implicated in the survival of senescent cells. By interfering with this binding, FOXO4-DRI is studied for its ability to promote the targeted removal of senescent cells, which contribute to ageing.
Findings from early-stage clinical trials have reported:
- Selective elimination of senescent cells observed in-vivo across ageing research models.
- Improvements in tissue regeneration and functional recovery reported following senescent cell clearance.
- Reductions in systemic inflammatory markers associated with senescence noted in experimental cohorts.
- Observed improvements in physical vitality markers and organ function reported in animal studies.
Researchers study FOXO4-DRI to explore senolytic intervention strategies and the biological mechanisms governing cellular senescence. Its selective action on senescent cells makes it essential for research into longevity and age-related decline.
