Reagents in this Signaling Category
Semax
Heptapeptide ACTH(4-10) Analog (Met-Glu-His-Phe-Pro-Gly-Pro)
Semax is a synthetic regulatory heptapeptide structurally derived from an adrenocorticotropic hormone fragment (ACTH 4-10) stabilized with a C-terminal Pro-Gly-Pro tripeptide. Examined in neuropharmacology laboratories for its modulation of BDNF, trkB receptors, and cerebral monoamines.
Selank
Synthetic Tuftsin Heptapeptide Analogue (Thr-Lys-Pro-Arg-Pro-Gly-Pro)
Selank is a synthetic regulatory heptapeptide derived from the immunomodulatory tetrapeptide tuftsin, extended with a C-terminal Pro-Gly-Pro tripeptide. Examined in neuroimmunology laboratories for its allosteric modulation of GABAA receptors, enkephalinase inhibition, and IL-6 expression.
PT-141 (Bremelanotide)
Cyclo(1,6)-Ac-Nle-Asp-His-D-Phe-Arg-Trp-Lys-OH
PT-141 (Bremelanotide) is a synthetic cyclic heptapeptide analog of alpha-melanocyte-stimulating hormone (alpha-MSH) characterized by an intramolecular lactam bridge. Widely investigated across neurochemical laboratories as a selective agonist of central melanocortin MC3 and MC4 receptors.
