Cortagen

Overview

Cortagen is a synthetic tetrapeptide (Ala-Glu-Asp-Pro) bioregulator developed by Professor Vladimir Khavinson based on amino acid analysis of cortexin, a polypeptide preparation from the cerebral cortex with neurotrophic activity. It is classified as a cytogen that interacts directly with DNA to influence gene expression in neural tissue. Research focuses particularly on its regenerative effects on peripheral nerve tissue, with studies demonstrating axonal regeneration and functional recovery after sciatic nerve injury.

Mechanism of Action

Cortagen functions as a DNA-interacting cytogen, binding gene regulatory regions to activate transcription of previously repressed genes in aged neural tissue. It increases ribosomal gene activity through decondensation of nucleolus organizer regions (NORs), and unpacks age-condensed chromatin fibrils to release previously silenced genes. This mechanism is distinct from Pinealon (similar sequence but different target tissue) and allows targeted regulatory effects in cortical neural tissue. Research indicates it activates genes relevant to protein synthesis and cellular regeneration in neurons.

Potential Benefits

• Neural regeneration after peripheral nerve injury
• Axonal regrowth and functional recovery in nerve damage models
• Chromatin remodeling in aged neural cells releasing silenced genes
• Increased ribosomal gene activity supporting protein synthesis
• Complementary to Pinealon (cortagen provides regeneration, pinealon provides protection)
• Potential support for cortical neural tissue health in aging
