• •       Bronchogen (bioregulator peptide Bronchogen) is a linear small-molecule polypeptide composed of four amino acids (alanine-glutamic acid-aspartic acid-leucine, with the sequence AEDL). It belongs to the Khavinson peptide class of bioregulators and possesses a unique cell-penetrating ability, allowing it to enter the cell nucleus to exert biological effects.

    Physicochemical Properties

    • Chemical Structure: Its abbreviated chemical structure is H-Ala-Glu-Asp-Leu-OH, with a molecular formula of C₁₈H₃₀N₄O₉ and a molecular weight of approximately 446.45 Da.
    • Physicochemical Parameters: As an extremely short tetrapeptide, Bronchogen features low synthesis costs and relatively low purification difficulty. It is soluble in water (H₂O) and DMSO.

    Mechanism of Action and Potential Benefits
    Bronchogen primarily targets pulmonary cells, exerting regulatory effects at both the genetic and cellular levels:

    • DNA Stabilization and Gene Regulation: Bronchogen acts as a DNA stabilizer by binding to CNG-rich DNA sequences, which increases the DNA melting temperature and enhances its tolerance to oxidative damage. Furthermore, it interacts with genes related to lung development and function (such as NKX2-1 and SCGB1A1) to regulate gene expression, thereby supporting the regeneration and repair of lung tissue at the genetic level.
    • Anti-inflammatory Effects: Studies indicate that Bronchogen can downregulate pro-inflammatory cytokines (such as TNF-α and IL-6) and inhibit neutrophil-induced inflammatory responses. This helps alleviate chronic pulmonary inflammation and improves lung injuries caused by conditions like chronic obstructive pulmonary disease (COPD), asthma, or viral infections.
    • Tissue Repair and Regeneration: It specifically targets pulmonary epithelial cells, promoting the synthesis and secretion of pulmonary surfactants to maintain normal alveolar function. Additionally, Bronchogen aids in restoring the function of ciliated epithelial cells and reducing goblet cell hyperplasia, which alleviates excessive mucus secretion and airway obstruction, ultimately rebuilding a healthy pulmonary environment.
    • Anti-aging and Reversal of Functional Decline: Bronchogen exhibits gonadoprotective activity and can delay cellular senescence by reactivating aging DNA repair mechanisms. This helps reverse age-related declines in lung function.

    
    

      The core principle for storing parenteral lyophilized powder is strict refrigeration and absolutely no freezing. Before reconstitution, it is generally stored in the dark at 2 to 8°C. Once mixed and dissolved with the solvent, it must be used within a very short period.

Before Reconstitution (Original Packaging)

Strict Refrigeration: The vast majority of parenteral lyophilized powders need to be stored in a refrigerator at 2 to 8°C.

Absolutely No Freezing: Freezing will cause irreversible damage to the structure of proteins and peptides.

Protection from Light and Moisture: The product must be kept in its original packaging to avoid direct sunlight and accidental exposure to moisture.

After Reconstitution (Mixed State)

Highly Time-Sensitive: Once the lyophilized powder is dissolved with a sterile solvent, the stability of the drug drops significantly. It usually needs to be administered immediately or within a very short window (e.g., a few hours).

No Prolonged Storage: Under no circumstances should the reconstituted solution be stored in the refrigerator for use the next day. This can easily lead to loss of efficacy or severe bacterial contamination.
