Description
Semax is a synthetic heptapeptide. Specifically, it models a core fragment of adrenocorticotropic hormone (ACTH 4-10). Natural neuropeptides suffer from a short half-life. To solve this problem, scientists engineered this molecule. Consequently, it now features a protective C-terminal Pro-Gly-Pro (PGP) tripeptide extension. This specific shield prevents rapid enzymatic breakdown. Therefore, it drastically enhances metabolic stability and prolongs its active window in laboratory models.
Russian neuroscience research has rigorously evaluated Semax for decades. Furthermore, it remains a cornerstone molecule for investigating non-hormonal, neurotropic mechanisms. We manufacture every batch of Semax lyophilisate under stringent quality protocols. In addition, Janoshik Analytical independently validates each lot. For example, they use High-Performance Liquid Chromatography (HPLC) to confirm a final purity of ≥ 99%.
Primary Research Relevance
Specifically, models use Semax to study the following areas:
-
BDNF & Synaptic Plasticity: First, studies investigate how it upregulates Brain-Derived Neurotrophic Factor (BDNF). Additionally, researchers look at its role in TrkB receptor signaling and long-term potentiation (LTP).
-
Cognitive Frameworks & Neuromodulation: Second, preclinical assays utilize it to evaluate changes in learning velocity. It also helps model memory consolidation, exploration, and attention focus.
-
Neuroprotective Mechanisms: Third, cellular models map how this peptide mitigates neuronal apoptosis. It is therefore a primary model for studying hypoxia and oxidative stress.
-
Comparative Neuropeptide Profiles: Finally, side-by-side trials often pair it with Selank. This allows scientists to compare the diverging pathways of ACTH-derived and Tuftsin-derived peptides.
Frequently Asked Questions
What is Semax and how is it modified?
Semax is a synthetic analog of the ACTH(4-10) fragment. Specifically, we modify it by adding a stable Pro-Gly-Pro (PGP) tail. Most neuropeptides degrade very quickly. However, this tail protects the entire molecule. Because it resists breakdown, it preserves the compound’s core neurotropic activity for observation.
How does Semax differ from Selank in research?
Both are synthetic peptides. In addition, both are Russian inventions. However, they target different biological systems:
-
Semax acts on the melanocortin system. Primarily, it maps to BDNF expression and cognition.
-
Selank is derived from Tuftsin. Conversely, it maps to anxiolysis and GABA modulation.
What purity standards are utilized?
Janoshik Analytical validates every single batch. For instance, they use HPLC testing. This independent analysis confirms a purity profile of ≥ 99%. Additionally, the labs verify correct mass identity. They also check for heavy metals and bacterial endotoxins to ensure pristine baseline integrity.
How should Semax lyophilisate be stored?
Store the lyophilized powder refrigerated (2–8 °C). Make sure it is protected from all light, moisture, and UV exposure. Crucially, do not break the vacuum seal on the vial until you are ready for reconstitution.
