Research context

Semax is a synthetic heptapeptide with the sequence H-Met-Glu-His-Phe-Pro-Gly-Pro-OH, structurally derived from the ACTH(4-10) fragment of adrenocorticotropic hormone. In vitro and in animal models it has been studied as a modulator of neurotrophic and melanocortin-linked signaling. Reported interactions in the literature involve brain-derived neurotrophic factor (BDNF) and its receptor tyrosine kinase TrkB, as well as effects on monoaminergic pathways.

Research in isolated cell and rodent models has examined receptor binding and downstream signaling associated with the peptide, including changes in BDNF/TrkB expression, modulation of dopaminergic and serotonergic markers, and enzymatic stability and degradation profiles. Analytical characterization has employed reversed-phase HPLC and mass spectrometry to confirm identity, sequence, and purity of synthesized material.

This compound is supplied strictly for in-vitro laboratory research and analytical use. It is not intended for human or veterinary administration, and no statements herein constitute a therapeutic claim or dosing recommendation.
