Comparison

Epitalon vs Exenatide

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, Exenatide is used for type 2 diabetes treatment to improve glycemic control and modestly reduce body weight through GLP-1–like insulinotropic and glucagonostatic effects6768.

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, Exenatide is a 39-amino-acid exendin-4 peptide originally isolated from Gila monster venom that acts as a long-acting GLP-1 receptor agonist resistant to DPP-4 degradation67.

Length and Sequence

Epitalon is 4 amino acids long, whereas Exenatide is longer as it has a length of 39 amino acids. Epitalon is made up of a sequence of Alanine, Glutamic acid, Aspartic acid, Glycine. Exenatide 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

Exenatide

GLP-1 receptor (GLP1R) 6780

Organism or Origin

Epitalon

Synthetic peptide modeled after a pineal gland peptide fraction; not directly encoded as a standalone peptide in humans36

Exenatide

Originally from Heloderma suspectum (Gila monster) venom; now produced synthetically67
