🔬 What is N-Acetyl Selank Amidate?

N-Acetyl Selank Amidate is a synthetic heptapeptide with the modified amino acid sequence Ac-Thr-Lys-Pro-Arg-Pro-Gly-Pro-NH2 (Ac-TKPRPGP-NH2) . It is a chemically modified version of the parent peptide Selank, which itself is a synthetic analog of the endogenous human tetrapeptide tuftsin (Thr-Lys-Pro-Arg) . Selank was first developed in the 1990s and has been approved for use in Russia for the management of generalized anxiety disorder (GAD) .

The specific modifications on this product—N-terminal acetylation and C-terminal amidation—are designed to protect the peptide from exopeptidases, which cleave amino acids from the ends of peptide chains. This results in a significantly longer half-life and improved stability in biological systems .

The parent peptide Selank exerts its multifaceted effects by crossing the blood-brain barrier (BBB) and interacting with several key systems in the central nervous system (CNS) :

• GABAergic System Modulation: Selank is believed to act as a positive allosteric modulator of GABA signaling, the primary inhibitory neurotransmitter in the brain. This action reduces neuronal excitability and promotes relaxation, which is central to its anxiolytic effects .
• Enkephalin Upregulation: Studies report that Selank may block the activity of enzymes that break down enkephalins, the natural ligands for opioid receptors. Their upregulation may contribute to mood enhancement and stress reduction .
• BDNF Enhancement: Intranasal administration of Selank has been shown to upregulate the expression of brain-derived neurotrophic factor (BDNF) in the hippocampus. BDNF promotes neuronal survival and synaptic plasticity, contributing to improved cognitive function and resilience against stress .
• Serotonin Metabolism: Selank has been observed to enhance serotonin metabolism in the brain stem, which is crucial for mood regulation and emotional well-being .
• Immunomodulation: As an analog of the immunomodulatory peptide tuftsin, Selank has been studied for its ability to modulate cytokine balance, particularly under stress conditions .

🔎 Product Specifications & Technical Data

To ensure your research parameters are met with precision, here are the verified technical specifications for our N-Acetyl Selank Amidate peptide. Purity is a critical determinant of research accuracy, and our product meets the high standards expected by the scientific community .

🧪 Key Research Applications & Focus Areas

N-Acetyl Selank Amidate, leveraging the well-documented properties of the Selank peptide, is a powerful tool across a wide spectrum of neuroscience and immunological research .

• 🧠 Anxiety & Stress Research (GAD): The foundational application of this peptide analog. It is used to model interventions for generalized anxiety disorder (GAD) and stress-related conditions. Clinical studies on Selank have demonstrated anxiolytic effects comparable to traditional benzodiazepines like medazepam, but without the associated sedative, cognitive side effects, or addiction potential . Its proposed mechanism involves modulation of GABAergic and serotonergic systems .

• 🧬 Cognitive Enhancement & Nootropic Research: Selank has been shown to exhibit mild nootropic effects, improving memory retention and learning capacity in animal models . It has also been studied for its ability to mitigate the negative cognitive side effects (memory loss, attention deficits) associated with traditional anxiolytic medications . This makes the stabilized analog a key tool for studying the intersection of anxiety and cognitive function, potentially via its upregulation of BDNF in the hippocampus .

• 🛡️ Immunomodulation & Cytokine Research: Selank has demonstrated significant immunomodulatory effects, particularly under stress conditions. Studies have shown that it can reduce concentrations of pro-inflammatory cytokines like IL-1β, IL-6, and TGF-β1 while restoring levels of anti-inflammatory cytokines like IL-4 . It has also been shown to suppress the gene expression of IL-6 in the peripheral blood of subjects with depression, indicating its potential as an immunomodulator in stress-related and mood disorders .

• 🔄 Neuroprotection & Substance Withdrawal: Preclinical research indicates that Selank may possess neuroprotective properties and can attenuate withdrawal symptoms following substance abuse. Studies have shown its effectiveness in reducing anxiety and mechanical allodynia in models of alcohol withdrawal, as well as decreasing the overall withdrawal syndrome index in morphine-dependent models . These effects are thought to be linked to its modulation of the enkephalin system and BDNF expression .

📝 Handling, Storage, and Preparation for Research

Proper handling is critical to maintaining peptide integrity and ensuring experimental validity .

• Receiving & Storage: Upon receipt, store the lyophilized vial in a freezer at -20°C (-4°F) or below. Protect from light and moisture. Lyophilized peptide is stable for up to 24 months under these conditions .
• Reconstitution: To prepare stock solutions, briefly centrifuge the vial to concentrate the powder. It is recommended to reconstitute in sterile water or bacteriostatic water . Gently swirl or invert to dissolve; do not vortex.
• Dosage Considerations:
  • In vitro: Concentrations for cell culture studies are typically determined empirically based on the assay.
  • In vivo (Rodent): For reference, Selank has been studied in clinical settings at intranasal doses of up to 2700 mcg daily, divided into three administrations . Researchers must determine optimal dosing based on literature and IACUC guidelines.
• Preventing Adsorption: At low concentrations, peptides can adsorb to plastic surfaces. To prevent this, use low-protein-binding tubes.
• Safety & Handling: Always use personal protective equipment (PPE) such as gloves and safety goggles when handling. Work in a laminar flow hood or well-ventilated area. Dispose of all waste in appropriate biohazard containers .
