Pinealon

Pinealon is a synthetic 3-residue peptide whose sequence corresponds to the tripeptide L-glutamic acid, L-aspartic acid and L-arginine, written Glu-Asp-Arg. In the single-letter amino-acid code that reads as EDR, which is why the research literature commonly calls it the EDR peptide. The catalogue lists it in the neurobiology section and records no other catalogue synonyms.

The compound belongs to the group of short synthetic peptides described as peptide bioregulators, a class defined in the Russian-language gerontology literature. Peptides in that group are typically two to four residues long and are prepared by ordinary chemical synthesis rather than isolated from tissue. The sequence is linear, with a free N-terminal amine and a free C-terminal carboxyl and no recorded modification. Two acidic side chains and one basic side chain give the molecule a net charge across most of the ordinary buffer range.

The catalogue entry records no numerical identifiers: a CAS registry number, a molecular formula and a molecular weight are each not catalogued here, so none is stated. The material is supplied lyophilized in a 20 mg vial. Purity and identity are established by third-party HPLC and mass spectrometry, with a certificate of analysis for each lot. Pinealon is supplied strictly for laboratory research and is not for human or veterinary use, nor for consumption, administration, diagnostic use or therapeutic use.
