• Amino Acid Sequence: Ala-Glu-Asp-Pro (Alanine-Glutamic acid-Aspartic acid-Proline), with the single-letter sequence A-E-D-P.

• 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.

• 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.

      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.
