• 

• Core Basic Information:                                             

  • 1、Peptide Structure: A synthetic heptapeptide with the amino acid sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro (TKPRPGP), derived from a fragment of the human immunoglobulin G heavy chain, with three additional amino acids added to enhance its metabolic stability and duration of action.
  • 2、CAS Number: 129954-34-3; it appears as a white crystalline powder or solid, soluble in water, with a molecular weight of 751.87 and an isoelectric point of 9.83 (predicted).

• 

  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.
• Key Clinical Uses & Potential Benefits：                  

1、Most Common Adverse Events: Mild-to-moderate gastrointestinal symptoms (nausea, diarrhea, constipation), typically transient and resolving with dose titration
2、Contraindications: History of pancreatitis, severe gastrointestinal disease, or hypersensitivity to the peptide
3、Special Populations: Caution in patients with renal impairment; not recommended during pregnancy/lactation
