Product Details – Selank

Selank is a research solution that contains a synthetic peptide analog derived from the naturally occurring tetrapeptide tuftsin.

Selank has been structurally modified to enhance its stability and bioavailability during research applications. As a synthetic heptapeptide, Selank has been the subject of scientific interest due to its interaction with certain neurochemical systems in different research models.

This product is intended for laboratory research purposes only. It is not intended for human consumption, medical, or diagnostic use.

How Does Selank Work?

In preclinical and in vitro settings, Selank has been observed to interact with components of the central nervous system, particularly those involving neuropeptides and neurotransmitters such as serotonin and dopamine.

It is hypothesized to influence enzyme activity and receptor binding in certain experimental models. The nasal delivery method is used in research due to its potential to facilitate rapid systemic absorption through the nasal mucosa, bypassing first-pass metabolism.

Researchers utilize this format to examine the pharmacokinetic and pharmacodynamic properties of Selank under controlled conditions.

Research Findings on Selank

Research has shown that Selank, a synthetic peptide analog of tuftsin, can influence behavior in stress and withdrawal models. In a study using rats dependent on morphine, a single dose of Selank reduced several behavioral signs associated with withdrawal, such as convulsions and sensitivity changes, compared with control animals. These results suggest that Selank affects nervous system responses in experimental models of drug withdrawal and stress behaviors.

Other experiments in rats have examined Selank’s effects on brain‑derived neurotrophic factor (BDNF) and cognitive outcomes in models of chronic ethanol exposure. In these studies, Selank prevented changes in BDNF levels in the hippocampus and prefrontal cortex that were induced by long‑term ethanol intake and withdrawal. These findings indicate that the peptide may modulate neurotrophin expression and related pathways in research settings investigating neurochemical responses to chronic stressors.

Note: Selank is not approved by the FDA for medical use. It is available for research purposes only.
