Comparison

PEG-MGF vs Setmelanotide

Function

While PEG-MGF is used experimentally to enhance muscle repair and hypertrophy after mechanical overload or injury by stimulating satellite-cell activation and protein synthesis6373138, 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.

Mechanism

While PEG-MGF works as a poly(ethylene glycol)-conjugated form of Mechano Growth Factor (IGF-1Ec splice variant) comprising the 24-aa C-terminal E-peptide of IGF-1, designed to extend half-life while activating IGF-1 receptor–mediated anabolic signaling in muscle satellite cells637322138, 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.

Length and Sequence

PEG-MGF is 24 amino acids long, whereas Setmelanotide is shorter as it has a length of amino acids. PEG-MGF is made up of a sequence of Tyrosine, Glutamine, Proline, Proline, Serine, Threonine, Asparagine, Lysine, Asparagine, Threonine, Lysine, Serine, Glutamine, Arginine, Arginine, Lysine, Glycine, Serine, Threonine, Phenylalanine, Glutamic acid, Glutamic acid, Arginine, Lysine. Setmelanotide is made up of a sequence of sequence data not available in the current dataset.
