Product Information
Semax | ACTH(4-7)-PGP Neuropeptide — Research Grade
Semax (Met-Glu-His-Phe-Pro-Gly-Pro) is a synthetic heptapeptide derived from the ACTH 4-7 core sequence with a Pro-Gly-Pro C-terminal extension added for metabolic stability. It is registered in Russia for ischaemic stroke, TBI, and optic nerve disease.
Mechanism of Action
- BDNF upregulation — preclinical studies report 1.5-2.5x increases in BDNF expression in hippocampal and cortical tissue
- MC4R/MC3R agonism — activates melanocortin receptors involved in cognitive and anti-inflammatory signalling
- VEGF stimulation — promotes vascular remodelling in ischaemia models (MCAO)
- Dopamine/serotonin effects — studied for modulation of dopaminergic turnover in prefrontal cortex
Research Areas
Semax is studied in stroke recovery, cognitive enhancement, ADHD-like models, anxiety, and neuroprotection. It does not elevate IGF-1, distinguishing it from GH-axis peptides.
For Research Use Only. Rainbow Peptide supplies Semax exclusively for in vitro and laboratory research purposes. Not for human or veterinary use.
