Selank is a synthetic heptapeptide analog derived from the naturally occurring peptide tuftsin. It has been widely utilized in neuroscience and behavioral research for its potential effects on neurotransmitter modulation, stress response, and cognitive processes. Studies have shown that Selank interacts with GABAergic and monoaminergic systems, influencing the balance of serotonin and dopamine pathways. It is also being explored for its neuroprotective and anxiolytic-like properties, making it a valuable research tool in neurochemistry, psychopharmacology, and peptide-based signaling studies.
