Comparison
While AOD-9604 is studied as an anti-obesity peptide that can reduce weight gain and increase fat oxidation in obese animal models with generally neutral effects on IGF-1 and glucose metabolism in early human trials71111115, Melanotan I is approved in some regions for prevention of phototoxicity in erythropoietic protoporphyria and is studied as a skin-darkening, photoprotective peptide3444.
While AOD-9604 works as a synthetic fragment of human growth hormone corresponding to residues 176–191 with an added N-terminal tyrosine, retaining lipolytic but not growth-promoting actions; proposed to stimulate lipolysis and inhibit lipogenesis in adipose tissue, partly via β3-adrenergic pathways without significantly activating the full GH receptor–IGF-1 axis6171111, Melanotan I is a linear 13-amino-acid analog of α-MSH (afamelanotide) that selectively activates MC1R on melanocytes, increasing eumelanin synthesis and providing photoprotection3444.
AOD-9604 is 16 amino acids long, whereas Melanotan I is shorter as it has a length of 13 amino acids. AOD-9604 is made up of a sequence of Tyrosine, Leucine, Arginine, Isoleucine, Valine, Glutamine, Cysteine, Arginine, Serine, Valine, Glutamic acid, Glycine, Serine, Cysteine, Glycine, Phenylalanine. Melanotan I is made up of a sequence of Serine, Tyrosine, Serine, Nle, Glutamic acid, Histidine, Phenylalanine, Arginine, Tryptophan, Glycine, Lysine, Proline, Valine.
