Comparison
While Semax is used clinically in Russia for ischemic stroke and cognitive disorders; in models it improves learning, protects dopaminergic neurons, and modulates stress responses without significant endocrine ACTH-like effects166174, Setmelanotide is approved for chronic weight management in patients with POMC, PCSK1, LEPR deficiencies and Bardet–Biedl syndrome by reducing hunger and promoting weight loss92.
While Semax works as a synthetic heptapeptide, Met-Glu-His-Phe-Pro-Gly-Pro (MEHFPGP), that is an analog of ACTH(4–10) with a Pro-Gly-Pro extension and exerts neurotrophic and neuroprotective actions partly via upregulation of BDNF and modulation of dopaminergic and glutamatergic systems40162165174, Setmelanotide is a potent synthetic melanocortin-4 receptor (MC4R) agonist derived from a POMC/α-MSH–related sequence that restores downstream MC4R signaling in genetic obesity syndromes3192100.
Semax is 7 amino acids long, whereas Setmelanotide is shorter as it has a length of amino acids. Semax is made up of a sequence of Methionine, Glutamic acid, Histidine, Phenylalanine, Proline, Glycine, Proline. Setmelanotide is made up of a sequence of sequence data not available in the current dataset.
