Exenatide vs Vilon
Side-by-side comparison of key properties, dosing, and research.
- Summary
- Exenatide is a GLP-1 receptor agonist derived from the Gila monster lizard peptide exendin-4, with 53% homology to human GLP-1 and natural resistance to DPP-4 degradation. Available as twice-daily (Byetta) or once-weekly (Bydureon) formulation, it is also being studied for Parkinson's disease neuroprotection.
- Vilon is a synthetic dipeptide (Lys-Glu) derived from the thymus gland extract Thymalin. The shortest immune-regulatory peptide known, Vilon modulates T-cell and NK-cell function, extends lifespan in animal models, and shows epigenetic anti-aging activity. It is one of the Khavinson peptide bioregulators.
- Half-Life
- ~2.4 hours (Byetta/twice-daily); Bydureon BCISE: weekly via microsphere release
- Very short as a free dipeptide; effects mediated via gene regulation
