Where to buy N-Acetyl Selank Amidate for skiin care?Polypeptide.ltd,a reliable peptide supplier

N-Acetyl Selank Amidate is a modified form of the peptide Selank. Selank is a short nootropic and anxiolytic peptide originally developed in Russia. It is an analogue of naturally occurring tuftsin and has been shown to have immunomodulatory effects. Research suggests that Selank modifies gene expression in the brain, reducing the effects of the neurotransmitter GABA, altering cell membrane permeability, and enhancing production of brain-derived neurotrophic factor (BDNF).

The modified form of Selank, N-Acetyl Selank Amidate has a longer half-life and greater ability to cross the blood-brain barrier. It also has tighter receptor binding due to the amidation. Selank is currently being researched in animal models for the treatment of stroke and other ischemic brain diseases. It is also under consideration as a treatment of generalized anxiety disorder and to protect memory in the setting of neurodegenerative disease.

N-Acetyl Selank Amidate and DNA
Selank exhibits various effects, especially within the central nervous system, which have captured the attention of scientists. Studies conducted by Dr. Anastasiya Volkova at the Institute of Molecular Genetics in Russia suggest that Selank achieves these effects by modulating gene expression. In essence, Selank has the ability to activate or suppress specific segments of DNA, thereby influencing the functioning of our bodies. Research conducted on rats demonstrates that Selank alters the activity of at least 52 different genes.

N-Acetyl Selank Amidate and the Immune System
According to Dr. Olga Uchakina, a recipient of a Rockefeller Foundation grant and affiliated with Mercer University School of Medicine, animal studies have demonstrated that Selank can suppress the production of the inflammatory cytokine IL-6. IL-6, or interleukin-6, is secreted by macrophages as well as cells in the bone marrow and blood vessels. It serves as an inflammatory marker for severe COVID-19 infection. IL-6 is involved in various functions, including the regulation of fever, neutrophil production, and B cell growth. Within the central nervous system, IL-6 is implicated in the consolidation of emotional memories during sleep and may act as a mediator of pain perception.

N-Acetyl Selank Amidate as Nootropic
No discussion of Selank would be complete without exploring its potential to enhance cognition. Extensive research has established a connection between Selank and alterations in gene expression patterns related to anxiety and coagulation. Moreover, further research conducted on rats demonstrates that the nasal administration of Selank leads to changes in mRNA levels for 36 different genes associated with plasma membrane function, as well as ion-dependent learning and memory functions.

The Purpose of N-Acetylation
N-Acetyl Selank Amidate exhibits similar effects to Selank, as discussed earlier, which raises the question of why modify the original compound. N-acetylation is a common modification found in natural peptides, particularly in eukaryotes. In fact, most proteins in our bodies undergo N-acetylation. In yeast and humans, N-acetylation serves multiple roles, including:

Modifying protein-protein interactions.
Influencing subcellular localization.
Altering the three-dimensional folding of proteins.
Affecting degradation rates.
In synthetic chemistry, N-acetylation is used to modify the charge, hydrophobicity, and size of a protein. This can impact the protein’s stability, its distribution within the body, and its binding to receptors. In most cases, N-acetylation is performed to extend the half-life of a protein without significantly affecting its overall function. It is a relatively straightforward process, making it a cost-effective and well-established approach to enhance the potency of a peptide.

The Purpose of Amidation
Amidation is another peptide modification that occurs at the carboxyl group, located at the opposite end of the amino acid chain. Similar to N-acetylation, amidation is a natural process found in approximately half of all known peptides. Amidation renders peptides less susceptible to proteolytic degradation and prolongs their half-life in the bloodstream. Amidated peptides exhibit reduced sensitivity to pH changes and have a higher affinity for their receptors. They also exhibit stronger binding to their target receptors, thereby extending the effects of amidated proteins compared to their non-amidated counterparts. Natural peptides such as oxytocin, thyroid-releasing hormone, and vasopressin demonstrate significantly enhanced biological activity through amidation.

In synthetic biology, amidation serves three primary functions. Firstly, amidation aids in the protection of orally administered peptides against the harsh environment of the stomach and gastrointestinal (GI) tract. The stomach’s acidic pH, which is typically below 2, poses a challenge for the survival of many peptides. The presence of an amide group enables proteins to pass through the stomach without degradation, reducing the quantity of peptide required to be consumed in order to achieve desired concentrations in the bloodstream.

The second rationale for amidating synthetic peptides is to enhance their potency after absorption. Amidated proteins not only exhibit prolonged survival in the bloodstream but also bind more strongly to their target receptors, leading to enhanced signaling [12]. This aspect is especially significant for peptides with activity in the central nervous system, such as Selank. Although Selank demonstrates better penetration of the blood-brain barrier (BBB) compared to many other compounds, its ability to enter the central nervous system is still somewhat limited. By increasing the potency of the peptide, its effects in the CNS can be amplified and more pronounced.

Lastly, amidation also affects the lipid solubility of a compound. Although this function is not as pivotal as the previously mentioned ones, it is worth noting that amidation increases the compound’s lipid solubility, resulting in greater penetration of Selank across the blood-brain barrier (BBB). Therefore, amidated Selank not only exhibits enhanced potency through improved receptor binding but also enables a larger quantity of the peptide to reach the receptors in the central nervous system. In this case, the single process of amidation offers two distinct benefits that synergistically contribute to the overall effectiveness of Selank.
