Semax

What is Semax?
Semax is a synthetic heptapeptide with the amino-acid sequence Met-Glu-His-Phe-Pro-Gly-Pro. It was developed from the ACTH(4–7) fragment and modified to improve stability while retaining neurological activity without the hormonal effects associated with full-length ACTH.

Research Interest
Semax has been investigated in neurological and cognitive research involving learning, memory, attention, neuroprotection, cerebral ischemia, and recovery following neurological stress. Much of the published research originates from Russian neuroscience and pharmacology programs, where Semax has been studied in both preclinical models and human clinical settings.

Mechanism of Action
Research suggests that Semax influences multiple signaling pathways involved in neuronal function and adaptation. Reported effects include modulation of brain-derived neurotrophic factor (BDNF) and related neurotrophin signaling, changes in gene expression, regulation of dopaminergic and serotonergic systems, and effects on oxidative stress and inflammatory pathways.

Current State of Research
Semax has a substantial history of experimental and clinical research in Russia and surrounding regions, particularly in neurological and cognitive applications. It remains an investigational peptide in many countries, and research continues to explore its effects on neuroplasticity, cognition, neuroprotection, and recovery following neurological injury or stress.
