Selank is a synthetic heptapeptide developed at the Russian Academy of Sciences, derived from the immunomodulatory peptide tuftsin (with a stabilizing C-terminal tripeptide extension).

In preclinical and limited clinical research it has been studied for anxiolytic-like effects, modulation of monoamine neurotransmission, and influence on the expression of brain-derived neurotrophic factor (BDNF) and enkephalin-degrading enzymes.

Most published research originates from Russian laboratories. It is used as a research tool in studies of regulatory peptides and stress-related behavior.
