Cortagen is a synthetic tetrapeptide (Ala-Glu-Asp-Pro, AEDP) obtained by directed synthesis based on the amino-acid analysis of Cortexin, a polypeptide preparation from bovine cerebral cortex. It is a defined synthetic peptide, not itself an extract. It has the molecular formula C17H26N4O9, a molecular weight of approximately 430.41 g/mol, CAS number 335591-03-2. Its sequence is Ala-Glu-Asp-Pro (AEDP). The originating patent characterizes the material as a white amorphous odourless powder. AEDP is reported in the literature to interact with DNA and chromatin in cultured cells; no specific receptor target is established.
