Chonluten
Also known as: Glu-Asp-Leu, Khavinson bronchial peptide, Lung tripeptide bioregulator
Chonluten is a tripeptide bioregulator (Glu-Asp-Leu) developed by Professor Vladimir Khavinson, tissue-specific to the bronchi and lungs. While related to Bronchogen (a tetrapeptide), Chonluten is a shorter tripeptide sequence. It supports bronchial mucosal cell function, promotes respiratory epithelial regeneration, and is used in protocols for COPD, chronic bronchitis, and pulmonary anti-aging.
Half-Life
Short (minutes for the peptide); sustained gene-regulatory effects

Key Benefits
- Supports bronchial mucosal regeneration and repair
- May improve mucociliary clearance in chronic respiratory conditions
- Anti-inflammatory effects on bronchial epithelium
- Pulmonary anti-aging and tissue preservation
- Supports lung function in COPD and chronic bronchitis
- Well tolerated in combination with other Khavinson bioregulators
- Short tripeptide with efficient cellular penetration
Mechanism of Action
Chonluten's tripeptide sequence Glu-Asp-Leu interacts with gene regulatory regions in bronchial and alveolar cells, normalizing protein synthesis and cellular function. It promotes regeneration of respiratory mucosa, reduces inflammatory gene expression in bronchial tissue, and supports the ciliary function of bronchial epithelium. Its short sequence allows efficient cellular penetration and rapid gene-regulatory activity.
