Semax Nasal Spray

🔬 Product Overview: The Synthetic ACTH Fragment for Cognitive Neuroscience Research

Welcome to the forefront of cognitive neuroscience and neuroprotection research. At Buy Peptides Online USA, we are pleased to present our Semax Nasal Spray—a specialized, ready-to-use formulation of the synthetic heptapeptide (Met-Glu-His-Phe-Pro-Gly-Pro), designed for laboratory investigation into the mechanisms of neuroplasticity, learning, memory, and neuronal resilience.

Semax is a synthetic analog of the adrenocorticotropic hormone (ACTH) fragment 4-10, developed through rational drug design by Russian researchers at the Institute of Molecular Genetics and the Institute of Developmental Biology . Unlike its parent ACTH fragment, Semax incorporates a C-terminal prolyl-glycyl-proline extension, which significantly enhances its metabolic stability and confers unique nootropic and neuroprotective properties without the hormonal side effects of ACTH . It has been the subject of extensive research since its development in the 1980s, with numerous studies elucidating its effects on brain-derived neurotrophic factor (BDNF), neurotransmitter systems, and neuronal survival pathways .

Our nasal spray format offers researchers a practical, non-invasive delivery method for animal model studies, eliminating the variables associated with reconstitution and providing a consistent, metered dose for reproducible research protocols. Intranasal administration is the scientifically validated route for Semax research, providing direct delivery to the central nervous system via the olfactory and trigeminal pathways, bypassing the blood-brain barrier and first-pass hepatic metabolism .

🔍 What is Semax?

Peptide Structure and Nomenclature:
Semax is a synthetic heptapeptide derived from the ACTH(4-10) fragment with a C-terminal extension. It has the following precise characteristics :

The Critical Structural Modification:
The distinguishing feature of Semax is its C-terminal sequence. While the parent ACTH(4-10) fragment has known effects on attention and learning, it is rapidly degraded. The addition of Pro-Gly-Pro confers:

• Enhanced Metabolic Stability: The Pro-Gly-Pro sequence resists enzymatic degradation, significantly extending the peptide's half-life in biological systems .
• Increased Blood-Brain Barrier Penetration: The optimized structure facilitates transport across the blood-brain barrier .
• Unique Receptor Interactions: The extended C-terminus allows for interactions distinct from the parent ACTH fragment, contributing to its nootropic profile.

Mechanism of Action:
Semax acts through multiple, interconnected pathways to exert its neurobiological effects:

• BDNF Upregulation: Semax increases expression of brain-derived neurotrophic factor (BDNF) in the hippocampus and other brain regions, promoting neuronal survival, differentiation, and synaptic plasticity .
• Neurotransmitter Modulation: It modulates dopaminergic, serotonergic, and cholinergic neurotransmitter systems, enhancing cognitive processes .
• NGF Interaction: Semax binds to nerve growth factor (NGF) receptors, potentiating its neurotrophic effects .
• Antioxidant Activity: It exhibits antioxidant properties, protecting neurons from oxidative stress .
• Gene Expression Regulation: Semax influences the expression of genes involved in neuroplasticity and neuronal resilience .
