N Acetyl Selank Powder

N acetyl selank powder is a heptapeptide derivative created through the structural modification of the natural peptide Tuftsin. Developed through the iterative application of decades of peptide research from the Institute of Molecular Genetics of the Russian Academy of Sciences, it represents a research-grade peptide-specifically within the neuro-immunomodulatory category-that has undergone multiple rounds of structural optimization. Furthermore, backed by advanced peptide synthesis and modification technologies, a standardized quality control system, and a unique multi-target gene regulation mechanism, this product has become a key raw material for research in the field of neuro-immunology.If you want to learn more, contact Xi'an Sonwu Biotech Co., Ltd.

1. R&D History

The parent compound Selank was first synthesized in the 1990s by a Russian research team based on the endogenous human tetrapeptide Tuftsin, with a Pro-Gly-Pro tripeptide attached to its C-terminus. The N-acetylated product is an improved iteration of standard Selank. As an enhanced modification of native Selank, the N-acetylated form was designed to address its inherent limitations. The original peptide tends to be hydrolyzed by internal peptidases, remains active for only a short time, and delivers unsatisfactory bioavailability. Data regarding these modifications and target screening are documented in various Russian publications on fundamental peptide research; all findings are supported by data from in vitro cell assays and pharmacological studies in animal models, with no records of trial modifications driven by commercial agendas. During the R&D phase, target screening was conducted across three key areas-GABA receptor gene regulation, neurotransmitter metabolism, and cytokine regulation-establishing a mechanism of action involving synergistic multi-pathway effects that distinguishes this approach from the development of single-target chemical sedatives.

2. Mechanism of Action

At the molecular level, n acetyl selank powder does not directly or forcefully activate central receptors; instead, its primary modes of action involve regulating gene expression and fine-tuning neurotransmitter signaling across multiple systems. First, it targets central GABAergic pathways by upregulating transcription of genes encoding GABA receptor subunits in neurons; this prompts neurons to autonomously synthesize more inhibitory receptors, thereby indirectly optimizing the environment for central inhibitory neurotransmission-a mechanism distinct from the direct receptor-binding agonism characteristic of benzodiazepines. Second, it modulates the metabolic efficiency of monoamine neurotransmitters-such as serotonin, enkephalins, and dopamine-balancing the concentration ranges of various central excitatory and inhibitory neurotransmitters. Third, it upregulates BDNF (brain-derived neurotrophic factor) gene expression in the hippocampus and prefrontal cortex, and regulates the synthesis of proteins associated with neuronal oxidative stress, helping maintain neuronal physiological homeostasis. Fourth, it retains the inherent immunomodulatory properties of Tuftsin, balancing the secretion of inflammatory cytokines and regulating the basal activity of macrophages and natural killer (NK) cells, thereby achieving coordinated regulation across bidirectional neuro-immune pathways. Acetylation modification renders the peptide resistant to aminopeptidase hydrolysis and enhances its lipophilicity for blood-brain barrier penetration; consequently, at equimolar concentrations, its in vivo retention time is significantly superior to that of the unmodified parent compound, Selank.

1. Manufacturing

Mass production utilizes the mainstream industrial technique of Solid-Phase Peptide Synthesis (SPPS). Starting with Fmoc-protected amino acids, the process involves sequential peptide chain condensation, N-terminal acetylation (capping), deprotection, and cleavage to yield the crude peptide. The crude product undergoes multi-stage reversed-phase chromatography, concentration, and sterilization to produce the final white powder. The production workflow is distributed across three independent workshops-clean synthesis, purification, and sterile processing-with raw material charging and intermediate transfer conducted entirely in a Class 10,000 cleanroom, ensuring suitability for the long-term storage requirements of research-grade materials. Production formulas and process parameters are established in accordance with general pharmacopoeial standards for peptides, and intermediate samples are retained for every batch to facilitate traceability and verification.

2. Quality Standards

All finished products follow standard quality control protocols for research-use peptides. Every production batch comes with an independent third-party Certificate of Analysis (COA). Key tests cover HPLC purity, endotoxin levels, microbial counts, residual moisture, and related impurities. To meet specifications, the peptide purity must be at least 98%. We specifically remove leftover amino acids, cleavage agents, and short-chain peptide byproducts, and keep the moisture content under 3%. The full set of quality benchmarks aligns with established testing standards for research-grade peptides widely adopted in Europe and North America.

Adverse reactions observed in existing in vitro cell assays, animal administration studies, and limited human subject literature are mild and transient; there are no reports of severe organ damage.

1. Nasal administration: Transient stinging, dryness, or itching of the nasal mucosa-often caused by osmotic discomfort following powder reconstitution-can be mitigated by pre-moistening the nasal passages with saline.

2. Systemic administration: Occasional, brief headaches or mild drowsiness may occur initially; these are primarily physiological fluctuations resulting from short-term adjustments in neurotransmitter systems and resolve spontaneously as the administration regimen progresses.

3. High-concentration administration on an empty stomach: A very small number of subjects experienced mild gastric acidity or bloating; this can be alleviated by adjusting the timing of administration or by lowering the dose concentration.

4. Isolated cases of subjects with specific constitutions experiencing brief periods of vivid dreaming: This phenomenon is associated with memory consolidation mechanisms driven by the upregulation of BDNF in the hippocampus and is not considered a pathological adverse reaction. The overall incidence of adverse reactions decreases in tandem with dosage reductions, and the probability of adverse reactions occurring at standard research dosages is extremely low.
