Comparison

Argireline vs Setmelanotide

Function

While Argireline is a topical cosmetic peptide reported to decrease dynamic wrinkles by partially mimicking the mechanism of botulinum toxin in a non-invasive manner49, 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 Argireline works as acetyl hexapeptide-8 (Ac-Glu-Glu-Met-Gln-Arg-Arg-NH2), a SNAP-25–mimetic peptide that competitively inhibits SNARE complex assembly, reducing acetylcholine release at neuromuscular junctions and attenuating facial muscle contraction4959, 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

Argireline is 6 amino acids long, whereas Setmelanotide is shorter as it has a length of amino acids. Argireline is made up of a sequence of Glutamic acid, Glutamic acid, Methionine, Glutamine, Arginine, Arginine. Setmelanotide is made up of a sequence of sequence data not available in the current dataset.

Receptor

Argireline

Molecular target is the SNARE complex component SNAP-25 rather than a classical receptor; it interferes with SNAP-25 participation in vesicle fusion49

Setmelanotide

Melanocortin-4 receptor (MC4R) 3192100
