What is Semax? ACTH Research Peptide Guide UK. Semax is a synthetic analogue of ACTH(4-10) — a fragment of adrenocorticotropic hormone — that has been studied in preclinical and clinical research for its effects on the central nervous system. Originally developed in Russia, it has attracted growing interest in the broader research community for its interactions with BDNF signalling, neuroprotective pathways, and cognitive biology models.
What is Semax Made From?
Semax is a heptapeptide with the sequence Met-Glu-His-Phe-Pro-Gly-Pro, derived from the ACTH(4-10) fragment. Unlike the parent hormone, Semax does not activate adrenocortical steroidogenesis, making it a selective tool for studying the neurological effects of ACTH-related peptides without the endocrine side-effects associated with full-length ACTH.
How Does Semax Work?
Research into Semax has focused on several interconnected pathways:
BDNF Expression
One of the most studied effects of Semax in preclinical models is its upregulation of BDNF (brain-derived neurotrophic factor) — a key mediator of neuronal survival, synaptic plasticity, and cognitive function. BDNF research is a major area of interest in neurodegeneration and cognitive biology.
Neuroprotection
Studies have explored Semax’s potential neuroprotective effects in models of ischaemic brain injury, oxidative stress, and neuroinflammation. It has been investigated in clinical settings in Russia for ischaemic stroke, though these applications remain outside approved use in the UK.
Dopaminergic and Serotonergic Modulation
Preclinical research has examined Semax’s interactions with dopaminergic and serotonergic neurotransmission pathways — areas of significant interest in mood, motivation, and cognitive research.
