Comparison

Epitalon vs Setmelanotide

Function

While Epitalon is reported to increase lifespan and reduce tumor incidence in animals, and to influence differentiation of neural and mesenchymal stem cells; is studied as an epigenetic regulatory peptide36, 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 Epitalon works as a synthetic tetrapeptide, Ala-Glu-Asp-Gly (AEDG), that has been shown to bind histones and modulate gene expression and chromatin state, with reported effects on pineal function, neurogenesis, and longevity in animal models36, 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

Epitalon is 4 amino acids long, whereas Setmelanotide is shorter as it has a length of amino acids. Epitalon is made up of a sequence of Alanine, Glutamic acid, Aspartic acid, Glycine. Setmelanotide is made up of a sequence of sequence data not available in the current dataset.

Receptor

Epitalon

Binds nuclear histone proteins (H1, H2B, H3, H4) rather than a classic membrane receptor36

Setmelanotide

Melanocortin-4 receptor (MC4R) 3192100

Organism or Origin
