      Product Introduction  


          Cortagen is a synthetic tetrapeptide bioregulator composed of four amino acids. Below is a detailed introduction to it:
    1. Amino Acid Sequence and Chemical Structure
    • Amino Acid Sequence: Ala-Glu-Asp-Pro (Alanine-Glutamic acid-Aspartic acid-Proline), with the single-letter sequence A-E-D-P.
    2. Physical and Chemical Properties
    • Substance Classification: It belongs to small-molecule linear polypeptides (synthetic tetrapeptides).
    • Physicochemical Parameters: Its molecular formula is C₁₇H₂₆N₄O₉, with a molecular weight of approximately 430.41 Da. The theoretical isoelectric point (pI) is approximately 3.8, making it acidic overall.
    • Physicochemical Characteristics: It typically appears as a white or off-white powder. It exhibits excellent water solubility (highly soluble in water, PBS, and normal saline) but is insoluble in organic solvents and lacks significant lipophilicity.
    3. Main Functions and Mechanisms
    As a core member of the Khavinson family of bioregulatory peptides, Cortagen primarily functions through epigenetic regulation and the modulation of gene expression. Its core effects include:
    • Nerve Repair and Myelination: It accelerates the structural and functional recovery of damaged peripheral and central nerves, promotes myelination of nerve fibers, improves nerve conduction, and helps alleviate neuropathic pain.
    • Immunomodulation and Anti-inflammation: It stimulates the expression of interleukin-2 (IL-2) and enhances T-cell activity. Simultaneously, it inhibits the NF-κB pathway, mitigating inflammatory responses in the nervous system and throughout the body, thereby reducing the risk of autoimmune disorders.
    • Antioxidant and Anti-aging: It restores the balance between pro-oxidant and antioxidant systems in the body, scavenges free radicals, and reduces oxidative damage. This delays cellular senescence and improves age-related declines in neurological and immune functions.
    • Cognitive Enhancement and Mood Regulation: It has a positive impact on memory and attention in the brain and can induce motor stimulation. It shows potential benefits in treating affective/depressive symptoms without causing adverse effects on emotional-affective behavior.
    • Cardiovascular Protection: Studies indicate that Cortagen has specific effects on cardiac gene expression, regulates heart function, improves cardiovascular parameters, and demonstrates potential in protecting against myocardial ischemia-reperfusion injury.

     How to store  


          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.
