Product Description

Semax is a synthetic analogue of adrenocorticotropic hormone (ACTH) fragment 4-10. It is a heptapeptide with the sequence Met-Glu-His-Phe-Pro-Gly-Pro. Research has examined its nootropic, neuroprotective, and neurorestorative properties, including effects on BDNF expression and cognitive function. Semax has been studied for its influence on neurotransmitter systems and its ability to cross the blood-brain barrier, making it a key compound in neuroscience and cognitive research. Supplied at ≥98% HPLC-verified purity with full batch analytical documentation.

This product is intended for in-vitro research and laboratory use only. Not for human consumption.

Research Overview

Semax is a synthetic heptapeptide derived from the adrenocorticotropic hormone (ACTH) fragment 4-10, with the sequence Met-Glu-His-Phe-Pro-Gly-Pro. Developed by the Institute of Molecular Genetics of the Russian Academy of Sciences, Semax has been approved as a pharmaceutical agent in Russia and Ukraine for neurological applications. Research focuses on its ability to modulate brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) expression, conferring neuroprotective properties particularly relevant to ischaemic brain injury research. Studies have documented its effects on dopaminergic and serotonergic neurotransmitter systems, suggesting broad neuromodulatory activity beyond simple ACTH fragment effects. Semax has been clinically documented in stroke rehabilitation literature, where its neuroprotective and neurorestorative properties have been examined in post-ischaemic recovery models. The peptide crosses the blood-brain barrier efficiently, enabling central nervous system activity following peripheral administration. Researchers in neuroscience and cognitive pharmacology consider Semax a significant tool for studying neuroplasticity, neurotrophic factor regulation, and cognitive enhancement mechanisms in preclinical and clinical contexts.

Laboratory Handling

  • Store lyophilised vials at -20°C for maximum stability. Reconstituted solution should be kept at 2-8°C and used within 4 weeks.
  • Reconstitute with bacteriostatic water using gentle swirling. Avoid vortexing or vigorous shaking.
  • Handle under aseptic conditions. Use sterile syringes and alcohol-swabbed vial stoppers during reconstitution.
  • Avoid repeated freeze-thaw cycles. Prepare single-use aliquots from reconstituted stock for best experimental reproducibility.
