Research Comparison
Semax vs Selank: Two Neuropeptide Research Compounds Compared
Semax and selank are both synthetic peptides developed at the Institute of Molecular Genetics of the Russian Academy of Sciences. Despite being developed in the same laboratory, they derive from different parent molecules and have distinct molecular targets.
Molecular Origins
Semax is a 7-amino-acid analog of the ACTH(4-10) fragment (Met-Glu-His-Phe-Pro-Gly-Pro, MW 813.97 Da). It retains neurotropic properties without adrenocorticotropic activity. Dolotov et al. (2006, PMID: 16996037) observed BDNF upregulation in hippocampal tissue.
Selank is a 7-amino-acid analog of tuftsin (Thr-Lys-Pro-Arg) with a Pro-Gly-Pro extension for metabolic stability (MW 751.87 Da). Zozulia et al. (2008, PMID: 18454096) conducted a human RCT comparing its anxiolytic profile.
