Anti-Aging & Longevity
Chonluten
Summary
PE-22-28 is a synthetic analog of spadin derived from sortilin, designed to block TREK-1 potassium channels with rapid-onset antidepressant and neurogenic effects. It shows fast-acting depression relief (within 24 hours) and promotes hippocampal neurogenesis.
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
Relatively short; CNS effects may persist due to neurogenic mechanisms
Short (minutes for the peptide); sustained gene-regulatory effects
Admin Route
SubQ, Intranasal
SubQ, Oral
Research
Typical Dose
200–400 mcg
10 mg per day
Frequency
Once daily
Daily for 10–30 days
Key Benefits
  • Rapid-onset antidepressant effects (within 24 hours)
  • Promotes hippocampal neurogenesis
  • Improves cognitive performance and memory
  • Reduces anxiety and depressive behavior
  • Novel mechanism — does not act on serotonin/dopamine/GABA receptors directly
  • May help treatment-resistant depression
  • Neuroprotective effects
  • 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
Side Effects
  • Generally well tolerated in animal models
  • Limited human data available
  • Possible mild headache or transient mood changes at initiation
  • Injection site reactions (SC)
  • Generally well tolerated
  • Mild injection site reactions possible
  • No significant adverse pulmonary events reported
