**Definition:**
Epithalon is a synthetic tetrapeptide with the sequence Ala-Glu-Asp-Gly. It is widely recognized for its anti-aging properties and ability to activate telomerase, an enzyme crucial for cellular longevity.
**Function:**
Epithalon functions as a potent telomerase activator, promoting telomere elongation and enhancing cellular lifespan. It has demonstrated geroprotective effects, including the inhibition of spontaneous tumor development in mice and the restoration of circadian rhythms in aging organisms. Additionally, it increases neuronal activity and supports retinal function, making it a versatile bioactive peptide.
**Applications:**
Epithalon is primarily used in research and clinical settings for its potential in treating age-related conditions, cancer, and retinal degenerative diseases like Retinitis Pigmentosa. It is also studied for its ability to improve visual function and extend lifespan in model organisms.
