A polypeptide complex rather than a single defined peptide sequence.
Part of the Neuropeptides & signaling cluster
Overview
Cortexin is a low-molecular-weight polypeptide complex extracted from cerebral cortex tissue, studied largely in Russian neuroscience literature. It is marketed as a drug in some countries but is not authorized by Health Canada.
Source & context
Biological / chemical source: Bovine (or porcine) cerebral cortex extract
Primary research or clinical context: Marketed as a drug in some countries; not authorized by Health Canada
A mixture, not one peptide
Unlike single-sequence peptides, cortexin is a defined-molecular-weight fraction of many short peptides and amino acids. This is why it has no single sequence and is described as a polypeptide complex in the literature.
Evidence and regulatory note
Most published studies originate from a limited set of laboratories and use animal or small clinical designs. Availability differs by country; this page is educational and does not present cortexin as a treatment.
