Comparison

Liraglutide vs Selank

Function

While Liraglutide is approved for type 2 diabetes and weight management, improving glycemic control and inducing weight loss through GLP-1–mediated insulinotropic, glucagonostatic, and appetite-suppressing actions6880, 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.

Mechanism

While Liraglutide works as a human GLP-1 analog with a single amino-acid substitution (Lys34→Arg) and a C16 palmitoyl fatty acid attached to Lys26 via a glutamate linker, producing a long-acting GLP-1 receptor agonist6880, Selank is 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.

Length and Sequence

Liraglutide is 31 amino acids long, whereas Selank is shorter as it has a length of 7 amino acids. Liraglutide is made up of a sequence of sequence data not available in the current dataset. Selank is made up of a sequence of Threonine, Lysine, Proline, Arginine, Proline, Glycine, Proline.
