Semax (25mg) Research Peptide: A Synthetic Heptapeptide for Cognitive & Neuroprotection Studies

If your research involves cognitive enhancement, neuroprotection, or the molecular mechanisms of brain repair, Semax (25mg) research peptide is a compound that deserves your attention. This synthetic heptapeptide (Met-Glu-His-Phe-Pro-Gly-Pro) is a structural analogue of the adrenocorticotropic hormone fragment ACTH(4-10), but without its hormonal activity. Developed in Russia, Semax has been extensively studied for its nootropic (cognitive-enhancing) and neuroprotective properties. It is known for its ability to form stable complexes with copper(II) ions, which may contribute to its neuroprotective effects by modulating metal-induced oxidative stress.

At Wuhan Top Miracle Peptides, we supply high-purity Semax (25mg) research peptide to research institutions and wholesale buyers across the United Kingdom, France, Germany, Spain, Sweden, Italy, and the USA. Every batch is lyophilised, HPLC-verified to ≥99% purity, and accompanied by a Certificate of Analysis (COA), ensuring your investigations into cognitive function, neuroprotection, and gene expression begin with uncompromising quality.

What Is Semax and How Does It Work?

To fully appreciate the research potential of Semax (25mg) research peptide, it is essential to understand its molecular design and the mechanisms by which it exerts its effects on the central nervous system.

The MEHFPGP Heptapeptide

Semax is a synthetic heptapeptide consisting of seven amino acids: methionine, glutamic acid, histidine, phenylalanine, proline, glycine, and proline—the sequence Met-Glu-His-Phe-Pro-Gly-Pro (MEHFPGP). Its molecular formula is C₃₇H₅₁N₉O₁₀S, and its molecular weight is approximately 813.92 g/mol. It has a CAS number of 80714-61-0.

The peptide is a synthetic analogue of ACTH(4-10), a fragment of the adrenocorticotropic hormone. However, it has been engineered to retain the neuroactive properties of the parent molecule while eliminating its hormonal (steroidogenic) activity, making it a cleaner tool for neuroscience research.

Mechanism of Action: Multi-Target Neuromodulation

The biological activity of Semax (25mg) research peptide is rooted in its ability to interact with multiple neurotransmitter systems and gene expression pathways:

• Dopaminergic and Serotonergic Modulation: Semax has been shown to activate dopaminergic and serotoninergic brain systems in rodents. It enhances striatal dopamine release, which may underlie its effects on locomotor activity and motivation.

• Neurotrophic Signalling: Research suggests that Semax participates in neurotrophic signalling pathways, supporting cognitive coordination, stress-responsive adaptation, and neuroimmune communication.

• Copper Chelation and ROS Reduction: Semax is a copper chelator peptide that can extract Cu(II) from Cu(II)-amyloid beta species, influencing redox cycling and decreasing the level of associated reactive oxygen species (ROS) production. This mechanism may be relevant to neurodegenerative disorder research.

• Gene Expression Modulation: Semax affects the expression of genes related to the immune and vascular systems, particularly in the context of cerebral ischemia. It can alter the expression of genes that modulate the activity and mobility of immune cells.

• NMDA Receptor Interaction: Semax has been shown to affect the glycine site of the NMDA receptor, a key player in synaptic plasticity and memory formation.

Key Research Applications for Semax (25mg)

Semax (25mg) research peptide is a versatile tool with applications spanning several domains of neuroscience and molecular research.

Cognitive Enhancement and Nootropic Research

As a nootropic peptide, Semax has been studied for its ability to enhance memory, attention, and learning. Intranasal administration of Semax has been shown to improve memory deficiency in experimental models of chronic brain ischemia. In comparative studies, Semax has demonstrated nootropic efficiency, particularly after intranasal administration.

 Neuroprotection and Ischemic Stroke Research

Semax has a pronounced neuroprotective effect in the treatment of cerebrovascular insufficiency and acute cerebral stroke. Genome-wide transcriptional analysis in rat brain focal ischemia models has shown that Semax affects the expression of genes related to the immune and vascular systems. It effectively protects brain tissues against ischemic stroke.

Alzheimer’s Disease and Neurodegenerative Disorder Research

Semax has been assessed in transgenic mouse models of Alzheimer’s disease for its effects on behavioural characteristics and amyloidosis development. Its ability to chelate copper and reduce ROS production provides insights into its potential role in neurodegenerative disorders. Studies suggest that Semax may offer potential benefits to patients suffering from a variety of neurological conditions, including Alzheimer’s disease, traumatic brain injury (TBI), and stroke.

Stress, Anxiety, and Depression Research

Semax has demonstrated antidepressant-like and antistress effects in animal models. Chronic treatment with Semax reversed chronic unpredictable stress (CUS)-induced anhedonia, body weight gain suppression, adrenal hypertrophy, and a decrease in hippocampal levels of BDNF. It also attenuated markers of chronic stress load. Semax has also been shown to have anxiolytic properties.

Gene Expression and Neuroimmune Research

Semax serves as a valuable tool for studying how peptide fragments interact with receptor systems, gene expression pathways, and stress-responsive mechanisms. It predominantly enhances the expression of genes related to the immune system. It alters the expression of genes that encode chemokines and immunoglobulins, and enhances the activity of immune cells.

Chemical & Physical Specifications

Accurate characterisation of Semax (25mg) research peptide is essential for reproducible experimental design. Below are the verified specifications from multiple research suppliers.

Note: The 25 mg mass refers to the weight of the peptide in its lyophilised form. The peptide is often supplied as the acetate salt (CAS 2828433-33-4), which enhances aqueous solubility.

Reconstitution & Handling Protocol for Semax (25mg)

Proper reconstitution of Semax (25mg) research peptide is critical for maintaining its structural integrity and biological activity.

Step 1 – Preparation

• Bring the sealed Semax vial and your chosen diluent (sterile bacteriostatic water or sterile PBS, pH 5-7) to room temperature. Condensation can degrade the lyophilised powder.

• Clean your work surface with 70% ethanol and lay out sterile syringes, alcohol wipes and a clean work mat.

Step 2 – Vial Sanitisation

• Wipe the rubber stopper of the Semax vial with a fresh 70% ethanol wipe. Allow the alcohol to evaporate completely before piercing.

Step 3 – Reconstitution

• Draw your desired volume of diluent into a sterile syringe. A common starting concentration for research applications is 25 mg per 2.5 mL of diluent, yielding a 10 mg/mL stock solution.

• Insert the needle and slowly inject the diluent against the inner glass wall. Do not spray directly onto the lyophilised powder.

• Gently swirl the vial until the solution is clear and fully dissolved. Do not shake vigorously, as shaking can cause denaturation.

Step 4 – Aliquoting & Storage

• Immediately after dissolution, aliquot the reconstituted Semax into single‑use sterile vials.

• Store aliquots at –20°C. Avoid repeated freeze‑thaw cycles.

• Once thawed, store at 2‑8°C and use within 7 days.
