Neuropeptide research covers sequences acting on BDNF expression, monoamine systems and sleep architecture. The ACTH-derived and tuftsin-derived analogues in this section are among the most widely referenced.
Supplied as lyophilised powder with full analytical documentation.
Selank is the heptapeptide Thr-Lys-Pro-Arg-Pro-Gly-Pro. It incorporates the tuftsin sequence Thr-Lys-Pro-Arg and adds Pro-Gly-Pro, but it is not identical to tuftsin.
Selank has limited human comparative literature and a larger mechanistic narrative around GABA signaling. The human reports are small, mostly Russian-language, and…
Semax is the synthetic heptapeptide Met-Glu-His-Phe-Pro-Gly-Pro, also written ACTH(4–7)-Pro-Gly-Pro. It should not be confused with semaxanib, an unrelated small molecule with a…
