Selank

Selank, also known as TP-7 or by its sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro, is a synthetic neurotrophic peptide developed for laboratory research applications. This heptapeptide represents a synthetic analogue of tuftsin, a naturally occurring tetrapeptide involved in immune system modulation. The compound operates through a multifaceted mechanism of action that influences neurotransmitter balance within the central nervous system. Research indicates that Selank modulates serotonin and dopamine pathways, which are fundamental to mood regulation and cognitive processing. Additionally, studies demonstrate that this peptide enhances the expression of brain-derived neurotrophic factor (BDNF), a critical protein supporting neuronal growth, survival, and synaptic plasticity. In research models, Selank has demonstrated several notable effects. The literature reports anxiolytic properties without associated sedation, distinguishing it from traditional anxiolytic compounds. Cognitive function and memory enhancement have been observed in experimental settings, alongside improvements in mood stability and emotional regulation. The peptide also exhibits immunomodulatory properties, reflecting its structural relationship to tuftsin. Stress resilience represents another area of research interest, with studies indicating enhanced adaptation to stressful conditions in experimental models. The evidence base consists primarily of Russian clinical trials suggesting efficacy in anxiety reduction and cognitive enhancement. However, researchers note that these studies are limited in number and often lack rigorous placebo-controlled designs. The scientific community recognises the need for more extensive, well-controlled trials to fully establish the compound's research profile. Selank's classification as a neurotrophic peptide reflects its primary research applications in cognitive and neurological studies. The compound's unique mechanism, combining neurotransmitter modulation with neurotrophic factor enhancement, makes it a valuable tool for researchers investigating anxiety, cognition, and neuroprotection pathways.
