Comparison
While Dulaglutide is a once-weekly GLP-1RA for type 2 diabetes that lowers HbA1c and body weight by enhancing glucose-dependent insulin secretion and reducing appetite6668, Melanotan I is approved in some regions for prevention of phototoxicity in erythropoietic protoporphyria and is studied as a skin-darkening, photoprotective peptide3444.
While Dulaglutide works as a recombinant fusion protein consisting of two disulfide-linked GLP-1(7–37) analogs each covalently fused via a linker to an IgG4 Fc fragment, yielding a large, long-acting GLP-1 receptor agonist protected from DPP-4 degradation66, 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.
Dulaglutide is amino acids long, whereas Melanotan I is longer as it has a length of 13 amino acids. Dulaglutide is made up of a sequence of sequence data not available in the current dataset. Melanotan I is made up of a sequence of Serine, Tyrosine, Serine, Nle, Glutamic acid, Histidine, Phenylalanine, Arginine, Tryptophan, Glycine, Lysine, Proline, Valine.
