General description

Semax regulates the expression and the activation of the hippocampal (brain-derived neurotrophic factor) BDNF/(tropomyosin receptor kinase B) trkB system. It enhances selective attention at the time of information reception, increases memory consolidation and stimulates learning abilities. Semax is an active element of SEMAX drugs, which is used for the treatment of brain hypoxia and ischemia. It stimulates the activity of choline acetyltransferase. Semax exhibits properties of the melanocortin (MC) receptor antagonist.

Biochem/physiol Actions

Semax (Met-Glu-His-Phe-Pro-Gly-Pro) is an analog of the adrenocorticotropin fragment (4-10). It activates the transcription of neurotrophins and has neuroprotective and nootropic activity.
