Semax — compound background
Synthetic heptapeptide, ACTH(4-7) analogue
Semax was developed at the Institute of Molecular Genetics in Moscow by attaching the Pro-Gly-Pro tripeptide to the ACTH(4-7) fragment. That C-terminal addition is the entire design rationale: it confers resistance to the aminopeptidases that clear the parent fragment within seconds, without retaining the corticotropic activity of full-length ACTH.
Solubility & reconstitution
Small, highly polar, and freely water-soluble at any concentration used in laboratory work. At 813.9 Da it is among the smallest compounds in this catalogue, and dissolution is essentially instantaneous.
Storage
Sealed at -20 °C. Short periods at 2–8 °C are acceptable given the small, robust structure. Refrigerate at 2–8 °C, protected from light. The N-terminal methionine is the compound's principal chemical liability.
Commonly worked with for 2–3 weeks at 2–8 °C.
Stability
The Pro-Gly-Pro extension protects against enzymatic degradation in biological media. It provides no protection against oxidation in a storage vial — those are different problems with different countermeasures.
Reading the Certificate of Analysis
Verify the molecular ion at 813.9 Da and check for a +16 Da oxidised species. For a peptide this short, RP-HPLC resolves related substances well, so a clean single peak is a strong quality signal.
