Semax

Synthetic heptapeptide (ACTH(4-7) analog)

Semax is a synthetic heptapeptide derived from the ACTH(4-7) fragment. In the scientific literature it appears in neurological research, where attention has focused on peptide interactions in laboratory and model systems. This page provides neutral background about the molecule as a research material; it is not medical guidance and not for human or veterinary use.

Classification and structure

Semax is classified as a synthetic heptapeptide, an analog of the 4-7 fragment of adrenocorticotropic hormone (ACTH) extended with a Pro-Gly-Pro sequence. Its structure consists of seven linked amino-acid residues. It is handled exclusively as a research chemical for non-clinical laboratory investigation.

Areas of research

In the published literature, Semax appears in the following research areas.

• Neurological research — Studied in models examining neuropeptide activity, neural signaling, and brain-derived factors.
• Neurochemistry — Investigated in relation to peptide stability and receptor-level interactions in vitro.

As always in this library, describing a compound as “studied in” an area is a statement about where scientific attention has gone — not a claim that it produces any result in humans or animals.

Handling and verification

Store lyophilized material cold and protected from light and moisture; stability is reduced once reconstituted or opened. Every in-stock lot ships with a verifiable third-party Certificate of Analysis (COA).
