Comparison
While Selank is a peptide developed in Russia as an anxiolytic and nootropic; in animal models it reduces anxiety-like behavior and modulates immune parameters under stress39, Snap-8 is a cosmetic peptide studied for reducing wrinkle depth by inhibiting synaptic vesicle fusion and subsequent muscle contraction in facial expression muscles5060.
While Selank works as a synthetic heptapeptide, Thr-Lys-Pro-Arg-Pro-Gly-Pro, that combines a tuftsin fragment with a Pro-Gly-Pro motif and is reported to modulate GABAergic neurotransmission and cytokine balance while being resistant to proteolytic degradation39, Snap-8 is acetyl octapeptide-3 (Ac-Glu-Glu-Met-Gln-Arg-Arg-Ala-Asp-NH2), an extended analog of Argireline derived from the N-terminal region of SNAP-25 that competes with native SNAP-25 for binding to syntaxin-1, forming a non-functional SNARE complex and reducing neurotransmitter release5060.
Selank is 7 amino acids long, whereas Snap-8 is longer as it has a length of 8 amino acids. Selank is made up of a sequence of Threonine, Lysine, Proline, Arginine, Proline, Glycine, Proline. Snap-8 is made up of a sequence of Glutamic acid, Glutamic acid, Methionine, Glutamine, Arginine, Arginine, Alanine, Aspartic acid.
