Why Choose Our Peptide Products

Anti-anxiety effect: Anti-anxiety is one of Selank's core pharmacological functions. Numerous studies have confirmed that Selank has a significant and stable anti-anxiety effect. Of particular note is that when Selank is used in combination with traditional benzodiazepine anti-anxiety drugs, it not only synergistically enhances the anti-anxiety efficacy but also effectively reduces common adverse reactions of the latter, such as drowsiness, muscle relaxation, and cognitive decline, thereby improving the safety and tolerability of the medication.

Cognitive and memory improvement: Studies have found that Selank possesses clear "nootropic" properties. It can promote memory consolidation and storage processes, enhance information processing capabilities, and has a positive effect on multiple aspects of learning and memory, helping to improve cognitive function, especially in attention and short-term memory.

Immunomodulatory and anti-inflammatory effects: Selank also exhibits a bidirectional regulatory capacity on the immune system. It can regulate the gene expression levels of inflammatory response-related cytokines, exerting an anti-inflammatory effect, while also possessing certain antiviral activity and immunomodulatory functions. In addition, some studies have found that Selank also shows potential positive value in relieving stress-induced gastric ulcers and enhancing the body's ability to adapt to stressors.

ECHEMI Editorial Reference

Selank is a synthetic derivative of the tetrapeptide tuftsin that contains a proline-glycine-proline sequence at the C-terminus and has anxiolytic and anti-inflammatory activities. It increases the amplitude and discharge rate of inhibitory postsynaptic currents of neurons in the rat hippocampal CA1 region when used at a concentration of 1 μM. It decreases the level of affective responses and the number of erroneous escape attempts in rats in an acute stress situation, increases orientational-investigative responses of rats in an unfamiliar situation, and reduces the time mice spend immobile in the forced swim test. It increases locomotor activity of high-anxiety Balb/c, but not C57Bl/6, mice in the open field test. Selank (0.01 mg/kg) decreases verticalization induced by apomorphine in mice. It also decreases expression of the inflammation-related genesIl2rgandXcr1in mouse spleen after 90 minutes when administered at a dose of 100 μg/kg.
SELANK Synthetic is a single, non-glycosylated polypeptide chain containing 7 amino acids, having a molecular mass of 751.89 Dalton and a Molecular formula of C33H57N11O9.
