A short-peptide bioregulator originally derived from cerebral cortex tissue, studied in Russian gerontology and neuroscience literature for effects on neuronal function and cortical signaling.
Cortagen is one of the Khavinson peptide bioregulators, a class of short peptides and peptide complexes developed in Russia and originally isolated from animal cortical tissue. It belongs to a family of tissue-specific 'cytomax' and synthetic 'cytogen' peptides proposed by their developers to interact with the tissue of origin.
Cortagen is associated in this literature with the cerebral cortex and nervous system. Some sources describe a synthetic tetrapeptide analog (cited as Ala-Glu-Asp-Pro), though the commercial preparation is generally described as a short-peptide complex, so its precise molecular identity is not consistently reported.
Because reliable structural identifiers are not established across sources, molecular fields are left blank here. The material below summarizes the available scientific literature for reference purposes only.
The proposed mechanism in the Khavinson-school literature is 'peptide bioregulation,' in which short peptides are described as binding regulatory regions of DNA and modulating tissue-specific gene expression in the cells from which they were derived. For Cortagen, investigators focus on neuronal and cortical tissue.
These mechanistic descriptions come largely from the developers' own research group and remain areas of ongoing investigation rather than broadly independently confirmed pathways.
Khavinson and colleagues have published a body of work describing short cortical peptides in animal models of nerve injury and aging, reporting effects on neuronal markers and behavioral measures. These reports originate largely from a single research school and are summarized here strictly as published exploratory findings.
Review articles by Khavinson (e.g., in Bull Exp Biol Med and Neuro Endocrinol Lett) place Cortagen within the broader cytogen peptide framework and describe proposed geroprotective and neurotropic activity observed in laboratory studies.
