Selank: Anxiolytic Peptide Research Guide

> Educational Content Only: This compound is discussed for educational purposes only and is not currently offered by our company. Selank is a synthetic heptapeptide developed at the Institute of Molecular Genetics of the Russian Academy of Sciences. It is a derivative of the naturally occurring immunomodulatory peptide tuftsin (Thr-Lys-Pro-Arg), with an additional Pro-Gly-Pro sequence that enhances stability and adds unique biological properties. - Molecular Weight: 751 Da - Amino Acid Sequence: Thr-Lys-Pro-Arg-Pro-Gly-Pro (TKPRPGP) - Structural Basis: Tuftsin analog with C-terminal extension - Solubility: Water-soluble - Stability: Enhanced compared to native tuftsin due to Pro-Gly-Pro addition Selank exhibits a multi-faceted mechanism involving several neurotransmitter systems: - GABA-A Modulation: Allosteric modulation of GABA receptors - Benzodiazepine Site Interaction: May act at benzodiazepine binding sites - Distinct from BZD: Does not produce sedation or dependence profiles - Serotonin: Influences serotonin metabolism and receptor activity - Dopamine: Modulates dopaminergic signaling - Norepinephrine: Affects noradrenergic neurotransmission - BDNF Expression: May enhance brain-derived neurotrophic factor levels - Neuroplasticity: Potential effects on synaptic plasticity mechanisms - Gene Expression: Influences expression of memory-related genes - Tuftsin-like Properties: Retains some immunomodulatory effects of parent compound - Cytokine Balance: May influence inflammatory cytokine production Studies have investigated Selank in: - Generalized anxiety models - Stress-induced behavior changes - Anxiety-cognition interactions - Comparison with traditional anxiolytics Research areas include: - Learning and memory paradigms - Attention and focus studies - Cognitive decline models - Neuroprotection research Investigations have explored: - Novel anxiolytic mechanisms - Non-sedating anti-anxiety approaches - Nootropic compound development - Peptide-based CNS therapeutics Studies continue to examine: - Immune function modulation - Neuroimmune interactions - Stress-immune relationships | Research Area | Key Finding | |---------------|-------------| | Anxiety | Anxiolytic effects without sedation in animal models | | Cognition | Enhanced learning in various behavioral paradigms | | Gene Expression | Upregulates expression of 36 genes related to neurotransmission | | Stability | Greater metabolic stability than native tuftsin | | Side Effects | Low side effect profile in preclinical studies | Selank has been studied via: - Intranasal administration (most common in research) - Subcutaneous injection - Intraperitoneal injection (animal studies) For research purposes: - Store lyophilized at -20°C - Reconstitute with bacteriostatic water or saline - Protect from light - Stable for several weeks when refrigerated after reconstitution - Intranasal preparations may require specific formulation 1.
