FOXO4-DRI
Summary
Bronchogen is a tetrapeptide bioregulator (Ala-Glu-Asp-Leu) developed by Professor Vladimir Khavinson at the St. Petersburg Institute of Bioregulation and Gerontology. It is a tissue-specific bioregulator designed for the bronchi and lungs, promoting normalization of bronchial epithelial cell function. Research suggests benefits for respiratory health, protection against pulmonary aging, and support for bronchopulmonary conditions.
FOXO4-DRI is a D-retro-inverso peptide derived from the FOXO4 protein that selectively induces apoptosis in senescent cells. By disrupting the FOXO4-p53 interaction that keeps senescent cells alive, it triggers programmed cell death specifically in these aging, pro-inflammatory cells while sparing healthy tissue.
Half-Life
Short (minutes to hours); bioregulator effects are gene-mediated and longer lasting
Estimated 2-4 hours (D-amino acid confers resistance to proteolysis)
Admin Route
SubQ, Oral
Subcutaneous, Intraperitoneal (research)
Research
Typical Dose
10 mg per day
5 mg/kg in rodent studies; human equivalent approximately 0.5-1 mg/kg
Frequency
Daily for 10–30 days
3 consecutive days per cycle
Key Benefits
  • Tissue-specific support for bronchial and lung health
  • Promotes normalization of bronchial epithelial cell function
  • Potential benefits in chronic bronchitis and COPD support
  • Anti-aging effects on pulmonary tissue
  • May reduce frequency of respiratory infections
  • Supports lung function preservation with aging
  • Compatible with other Khavinson bioregulator peptides
  • Selectively clears senescent cells (senolytics)
  • Reduces senescence-associated secretory phenotype (SASP) and chronic inflammation
  • Demonstrated restoration of physical fitness in aged mice
  • May improve healthspan and reduce age-related tissue dysfunction
  • Potential for treatment of age-related pathologies driven by cellular senescence
  • Does not affect healthy non-senescent cells at therapeutic doses
Side Effects
  • Generally well tolerated in research studies
  • Mild local reactions at injection site (if injected)
  • No significant systemic side effects reported at standard doses
  • Limited human data; largely preclinical evidence
  • Possible temporary inflammatory response as senescent cells are cleared (senolytic effect)
  • Weight loss observed at high doses in rodent studies
  • Unknown long-term safety profile in humans
