01Mechanism of Action

Parameter

Bronchogen

Tirzepatide

Primary target

Bronchial epithelial cellsKuzubova 2015

GIP receptor (GIPR) + GLP-1 receptor (GLP-1R)Frias 2018

Pathway

Tissue-specific bioregulation → epithelial cell differentiation → ciliated cell restoration

Dual GIPR/GLP-1R agonism → ↑insulin (glucose-dependent), ↓glucagon, ↓gastric emptying, ↓appetite, ↑energy expenditure (via GIP component)Jastreboff 2022 Frias 2018

Downstream effect

Reversal of goblet cell hyperplasia, squamous metaplasia elimination, restoration of ciliated epithelium, normalized secretory IgA and surfactant protein B productionKuzubova 2015 Titova 2017

Profound glycemic improvement and weight reduction; cardiometabolic benefitsJastreboff 2022

Feedback intact?

—

Glucose-dependent insulin release preserves physiological feedback

Origin

Synthetic tetrapeptide (Ala-Glu-Asp-Leu) from Khavinson bioregulator framework

39-AA peptide with C-20 fatty-acid acylation. Single molecule with balanced GIP + GLP-1 affinityFrias 2018

05Administration Protocol

Parameter

Bronchogen

Tirzepatide

1. Research context only

Bronchogen has been studied exclusively in animal models and organotypic tissue culture. No approved formulation or human administration protocol exists.

Commercial: pre-filled pen / vial. Research lyophilised: bacteriostatic water per label.

2. Animal model protocol

In rat COPD models, tetrapeptide administered for 30-day course following 60-day NO₂ exposure. Route and exact dosing not specified in abstracts.Titova 2017 Kuzubova 2015

SQ — abdomen, thigh, or upper arm. Rotate weekly.

3. Organotypic culture

Bronchial tissue explants from young (3-week) and aged (18-month) rats cultured in medium containing 0.05 ng/mL bronchogen, demonstrating tissue-specific stimulation.Zakutskiĭ 2006

Once weekly, same day. Day change allowed if ≥3 days separate doses.

4. Khavinson bioregulator tradition

Part of Russian peptide bioregulator framework emphasizing tissue-specific low-dose effects. Typically administered parenterally in related peptides from this series.

Refrigerate 2–8 °C unopened. Room temp ≤30 °C up to 21 days after first use.
