D-Retro-Inverso-Variante eines FOXO4-Peptid-Fragments (LTLRKEPASEIAQSILEAYSQNGWANRRSGGKR — D-Aminosäuren in umgekehrter Sequenz)Механизм действия
Cetrorelix
Cetrorelix competitively and immediately blocks the pituitary GnRH receptor, rapidly suppressing LH and FSH release — without the initial hormone surge ('flare') of GnRH agonists.
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.

Frequently asked questions
- What is the difference between Cetrorelix and FOXO4-DRI?
- Cetrorelix is classified as "Исследования (прочее)", while FOXO4-DRI is classified as "Исследования (прочее)". Cetrorelix: Cetrorelix is a synthetic decapeptide and GnRH antagonist. It is used in assisted reproduction (IVF) to prevent a premature LH surge during controlled ovarian stimulation. 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. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Cetrorelix or FOXO4-DRI?
- The highest available evidence level is "РКИ на людях" for Cetrorelix and "Модель на животных" for FOXO4-DRI. 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 Cetrorelix and FOXO4-DRI in Germany and the United States?
- Германия: Cetrorelix — Рецептурный, FOXO4-DRI — Только для исследований. США: Cetrorelix — Рецептурный, FOXO4-DRI — Только для исследований. These are factual summaries with source and review date on the individual pages.
