Selank is a synthetic heptapeptide modeled after the endogenous peptide tuftsin, designed to exert central nervous system (CNS) effects with minimal side effects. It is primarily studied for its anxiolytic (anti-anxiety), nootropic (cognitive-enhancing), and immunomodulatory activities. Selank works by modulating neurotransmitter systems, including serotonin, dopamine, and GABA, and by influencing neurotrophic factors that support brain function.
Chemically modified for stability and resistance to enzymatic degradation, Selank is suitable for preclinical and laboratory research focused on stress response, anxiety disorders, cognitive enhancement, and neuroprotection.
Peptide Type: Synthetic heptapeptide
Mechanism of Action: Modulates CNS neurotransmitters and neurotrophic pathways
Primary Effects: Reduces anxiety, enhances learning and memory, and modulates immune function
Water-Soluble: Suitable for in vitro and in vivo studies
Stability: Resistant to rapid degradation for research applications
Studying stress, anxiety, and depression mechanisms
Investigating cognitive function and memory enhancement
Researching neurotransmitter regulation and neuroprotection
Evaluating immunomodulatory effects of CNS peptides
Selank is a stable, CNS-active heptapeptide with anxiolytic, cognitive-enhancing, and immunomodulatory properties, making it a valuable tool for preclinical research on anxiety, stress, cognition, and neuropeptide signaling.
Type: Synthetic heptapeptide
Amino Acid Sequence: Thr-Lys-Pro-Arg-Pro-Gly-Pro (based on tuftsin)
Molecular Weight: ~905 Da
Structure: Linear peptide with chemical modifications to enhance stability and resistance to enzymatic degradation
Origin: Derived from tuftsin, an endogenous immunomodulatory tetrapeptide
Neurotransmitter Modulation: Influences serotonin, dopamine, and GABA systems in the CNS
Neurotrophic Activity: Enhances brain-derived neurotrophic factor (BDNF) expression, supporting neuroplasticity and cognitive function
Anxiolytic Action: Modulates stress-related pathways without sedative effects
Immunomodulation: Alters cytokine production and immune response
CNS Activity: Reduces anxiety-like behavior, enhances memory and learning, and improves stress response
Cognitive Support: Supports attention, focus, and memory retention
Immune Interaction: May promote balanced immune signaling without immunosuppression
Water-Soluble: Easily dissolved for in vitro and in vivo studies
Chemical Stability: Resistant to proteolytic degradation due to structural modifications
Bioavailability: Suitable for intranasal or parenteral administration in research
Selank is a water-soluble, chemically stabilized heptapeptide that modulates CNS neurotransmitters, neurotrophic factors, and immune pathways.
