Selank, also known as TP-7,It is a structural analog of tuftsin, a naturally occurring human peptide involved in immune function, and has gained attention for its unique neuroregulatory effects, including anxiolytic (anti-anxiety), nootropic (cognitive-enhancing), and neuroprotective properties. Unlike many traditional psychotropic drugs, it boasts a low side effect profile and no risk of addiction or withdrawal syndrome, making it a promising option for managing mental health and cognitive issues.

Core Mechanism of Action:

1.Selank exerts its therapeutic effects through multiple synergistic pathways, primarily targeting the central nervous system (CNS) and immune system.
GABAergic System Modulation: It enhances the activity of the GABAergic system, the body’s main inhibitory neurotransmitter system, by increasing the affinity of GABA for its receptors, thereby reducing neuronal excitability and exerting a calming, anxiolytic effect.
2.Neurotransmitter Regulation: It modulates the levels and metabolism of monoamine neurotransmitters such as serotonin and dopamine, which play key roles in mood regulation, cognitive function, and stress response.
3.Neurotrophic Factor Enhancement: It significantly increases the expression of brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF), supporting neuron growth, survival, and repair, and enhancing neural plasticity.
4.Stress Response Regulation: It acts on the hypothalamus to modulate the secretion of corticotropin-releasing hormone (CRH), regulating the hypothalamic-pituitary-adrenal (HPA) axis and reducing the body’s stress response.

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.
