Semax is a synthetic heptapeptide analog of adrenocorticotropic hormone fragment 4-10, composed of the amino acid sequence Met-Glu-His-Phe-Pro-Gly-Pro. It exhibits neuroprotective, nootropic, and anxiolytic-like effects in preclinical models through mechanisms such as modulation of brain-derived neurotrophic factor (BDNF), enhancement of serotonergic and dopaminergic signaling, and inhibition of neuropeptide-degrading enzymes.
