    1. Basic Molecular Parameters (Industry Standard)

    Full Name: Cortagen (Cerebral Cortex Targeted Bioregulatory Tetrapeptide)

    Amino Acid Sequence: H-Ala-Glu-Asp-Pro-OH (Abbreviation: AEDP, Tetrapeptide)

    Molecular Formula: C₁₇H₂₆N₄O₉

    Molecular Weight: 430.41 g/mol

    CAS Number: 335591-03-2

    Appearance: Sterile lyophilized white powder, sealed vial packaging (main specifications: 10mg / 20mg per vial)

    Purity: ≥98% as verified by HPLC; full COA, HPLC chromatogram and MSDS are supplied with each batch

    R&D Background: A tissue-specific bioregulatory peptide developed by Professor Vladimir Khavinson at the Institute of Bioregulation and Gerontology, Saint Petersburg, Russia. Synthesized based on amino acid extraction from mammalian cerebral cortex, specially designed for epigenetic gene regulation of central nervous system cells.

    2. Core Mechanism of Action

    Cortagen penetrates the nucleus of neurons and glial cells, remodels chromatin architecture, and reactivates functional genes silenced by cellular aging:
    • Decondense compact heterochromatin, restore transcriptional accessibility of age-suppressed neural genes;
    • Upregulate expression of neurotrophic factors including BDNF, NGF and NT-3, boost neuronal protein synthesis and axonal regeneration;
    • Balance excitatory/inhibitory neurotransmitter pathways (glutamate & GABA) to stabilize cortical neural electrical activity;
    • Activate intracellular antioxidant enzymes to mitigate neuronal oxidative damage and lipid peroxidation;
    • Suppress excessive microglial activation and pro-inflammatory cytokines to relieve neuroinflammation;
    • Regulate lymphocyte gene expression to coordinate central nervous and peripheral immune functions;
    • Accelerate myelin sheath repair of damaged nerve fibers and restore neural signal conduction efficiency.

    3. Core Research Efficacy (For Laboratory Research Only)

    Central & Peripheral Nerve Repair

    Promote axonal regrowth and remyelination after cerebral ischemia, traumatic brain injury and peripheral nerve lesions; suitable for cell & animal models studying nerve injury recovery.

    Anti-Aging & Cognitive Regulation

    Reverse age-induced gene silencing in cortical neurons; improve learning, memory and object recognition capacity in aged preclinical models for senile cognitive decline research.

    Neuroprotective & Antioxidant Study

    Counteract excitotoxicity and oxidative stress in neural tissue; serve as core reagent for screening anti-neurodegeneration substances.

    Neuro-Immune Modulation

    Regulate cross-talk between central nerve system and immune cells; support experiments on neuroinflammation and autoimmune neurological disorders.
