Werkingsmechanisme
FOXO4-DRI
FOXO4-DRI is the D-retro-inverso variant of a peptide fragment of the FOXO4 transcription factor. In senescent cells, FOXO4 is bound to p53, which suppresses p53-mediated apoptosis — the cells survive in a secreting 'zombie-like' state (senescence-associated secretory phenotype, SASP). The DRI peptide disrupts this FOXO4-p53 binding, freeing p53, and the senescent cell initiates apoptosis. Healthy cells are largely unaffected because p53 is not held back by FOXO4 in them. This selectivity was the central finding of the original 2017 publication.
Glepaglutide
As a GLP-2 receptor agonist, glepaglutide has a trophic effect on the intestinal mucosa, enlarging the absorptive surface and thereby improving intestinal uptake of nutrients and fluid.

Frequently asked questions
- What is the difference between FOXO4-DRI and Glepaglutide?
- FOXO4-DRI is classified as "Onderzoek (overig)", while Glepaglutide is classified as "Onderzoek (overig)". FOXO4-DRI: Synthetic peptide with D-Retro-Inverso structure (all amino acids as D-form, sequence reversed), developed in 2017 as an experimental senolytic candidate. Goal: selective apoptosis of senescent cells via disruption of the FOXO4-p53 interaction. So far evaluated exclusively preclinically. Glepaglutide: Glepaglutide is a long-acting GLP-2 analogue (Zealand Pharma) intended to reduce the need for parenteral support in short bowel syndrome. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, FOXO4-DRI or Glepaglutide?
- The highest available evidence level is "Diermodel" for FOXO4-DRI and "Humane RCT" for Glepaglutide. A higher evidence level means more robust data, but says nothing about suitability for an individual. The full body of evidence is on each peptide's own page.
- What is the legal status of FOXO4-DRI and Glepaglutide in Germany and the United States?
- Duitsland: FOXO4-DRI — Alleen onderzoek, Glepaglutide — Niet goedgekeurd. Verenigde Staten: FOXO4-DRI — Alleen onderzoek, Glepaglutide — Niet goedgekeurd. These are factual summaries with source and review date on the individual pages.
