Bronchogen is the tetrapeptide Ala-Glu-Asp-Leu (AEDL), developed as a tissue-specific bioregulator for bronchial and pulmonary epithelium. It belongs to the Khavinson peptide class—short sequences acting through interaction with DNA regulatory regions and modulation of gene expression. In lung tissue, its mechanism is linked to influence on key transcription factors: NKX2-1, SCGB1A1, FOXA1, and FOXA2, which regulate normal development and maintenance of bronchial epithelium. This explains tissue specificity—the peptide does not act systemically but selectively supports cells of a defined type.
In COPD models in rats, Bronchogen administration normalized bronchoalveolar lavage cell composition: neutrophil levels and pro-inflammatory cytokines TNF-α and IL-8 decreased, while secretory IgA and surfactant protein B—two key elements of airway defense—were restored. Bronchial epithelial structure recovered: goblet cell hyperplasia decreased, ciliated and secretory cells regenerated, improving mucociliary clearance and reducing mucus burden.
In clinical observations in patients with chronic bronchopulmonary disease, course use of Bronchogen was associated with fewer exacerbations and improved respiratory function measures. These data remain at the level of observational studies, not large double-blind RCTs, requiring restrained interpretation. Nevertheless, the aggregate of preclinical and observational data makes Bronchogen a logical candidate for supporting respiratory system reserve.
🫁 Bronchial epithelium (recovery and protection): ★★★★☆
🔥 Anti-inflammatory profile (COPD models): ★★★★☆
🛡️ Airway immune defense (IgA, surfactant): ★★★☆☆
✅ Safety: ★★★★☆ (bioregulator class profile generally favorable)
⚠️ Possible sensations and side effects: usually neutral; limited human data
🤝 Combinations (goal → stack)
🫁 Pulmonary recovery → Bronchogen + Thymosin Alpha 1
🛡️ Immune background + respiratory defense → Bronchogen + LL-37
🔧 Tissue recovery → Bronchogen + BPC-157
