Crystagen
Also known as: EDP, Glu-Asp-Pro
Crystagen is a synthetic tripeptide (Glu-Asp-Pro, EDP) short-peptide bioregulator developed by Vladimir Khavinson and colleagues at the St. Petersburg Institute of Bioregulation and Gerontology as an immune-system bioregulator. The Khavinson group reports it modulates immune-cell gene expression and chromatin organization, influencing T-cell, B-cell, and thymic epithelial activity via direct peptide-DNA interaction. Evidence is confined to single-group preclinical and small clinical studies; it is not FDA-approved and lacks independent Western validation. No CAS Registry Number is listed for this peptide in major chemical databases.

Transport of Biologically Active Ultrashort Peptides Using POT and LAT Carriers
Ultrashort peptides (USPs), consisting of 2-7 amino-acid residues, are a group of signaling molecules that regulate gene expression and protein synthesis under normal conditions in various diseases and ageing. USPs serve as a basis for the development of drugs with a targeted mechanism of action.
