Advanced Neurotrophic, Nootropic & BDNF-Upregulating Heptapeptide

Investigate the forefront of neurobiology and cognitive science with Semax (10 MG), an elite-tier synthetic heptapeptide engineered for advanced laboratory research into cognitive enhancement, neuroprotection, and neuroplasticity. Originally developed by the Institute of Molecular Genetics of the Russian Academy of Sciences, Semax is structurally derived from an adrenocorticotropic hormone fragment, ACTH(4–7), and strategically elongated at the C-terminus with a Pro-Gly-Pro tripeptide motif. This specialized modification dramatically increases metabolic stability and affords robust resistance to peptidase degradation within complex biological models.

Unlike classical psychostimulants that exhaust catecholamine reservoirs and carry substantial addiction liability, Semax operates primarily by upregulating the synthesis and expression of brain-derived neurotrophic factor (BDNF) and its signaling receptor tropomyosin receptor kinase B (TrkB) within the hippocampus and basal forebrain. Furthermore, it rapidly activates serotonergic and dopaminergic brain systems while competitively inhibiting enkephalin-degrading enzymes (enkephalinases) to preserve endogenous circulating enkephalins. This multifaceted neurotrophic mechanism provides researchers with an exceptional model for studying memory formation, selective attention, ischemic neuroprotection, and synaptic plasticity without the confounding variables of psychostimulant crash or sedation.

Key Product Highlights

• BDNF & TrkB Upregulation: Rapidly stimulates the expression of brain-derived neurotrophic factor (BDNF) and tyrosine phosphorylation of its receptor, TrkB, within the hippocampus. This makes it a primary model for investigating hippocampal neuroplasticity and memory consolidation.

• Enkephalinase Inhibition: Competitively inhibits enkephalin-degrading enzymes. This biological action extends the biological residence of endogenous regulatory peptides and enkephalins to support research into natural stress mitigation and mood stability.

• Peptidase Degradation Resistance: Incorporates a protective C-terminal Pro-Gly-Pro tripeptide sequence. This structural shielding protects the core ACTH(4–7) pharmacophore against rapid enzymatic cleavage in cell cultures and systemic assays.

• Monoaminergic System Activation: Rapidly modulates and activates central serotonergic and dopaminergic neurotransmission. This facilitates laboratory studies on selective attention, focus, and behavioral conditioning without psychostimulant toxicity.

• Ischemic & Hypoxic Neuroprotection: Demonstrated in extensive literature to activate the transcription of neurotrophin genes (including Bdnf, Ngf, and Nt-3) following cerebral ischemia and hypoxia. This highlights its value in cellular neuroprotection models.

• Ultra-Pure Specification: Lyophilized and manufactured at an elite ≥99% purity level (HPLC verified) to guarantee absolute precision and flawless reproducibility in sensitive analytical assays.
