Description
Pinealon (Glu-Asp-Arg, or EDR) is a synthetic tripeptide composed of three amino acid residues: glutamic acid, aspartic acid, and arginine. As a short-chain peptide, it belongs to a class of compounds characterized by their compact molecular architecture and the polar, charged nature of their constituent residues. The sequence confers a net anionic character at physiological pH, a property that influences its interactions with cellular targets in experimental models.
The structural simplicity of EDR makes it a useful probe in laboratory investigations focused on peptide–receptor interactions and intracellular signaling cascades. Researchers working in peptide biochemistry employ such tripeptides to examine how short amino acid sequences modulate pathway responses within controlled, cell-based systems.
Pinealon has drawn interest in preclinical research contexts exploring neuronal and glial cell behavior, where short regulatory peptides are studied for their capacity to influence gene expression patterns and cellular homeostasis under defined experimental conditions. Its compact size facilitates uptake studies and mechanistic assays that would be more difficult to conduct with larger peptide constructs.
