Enhancing autophagy or increasing longevity by administration of urolithins
Disclosed are methods, compounds, and compositions useful for increasing autophagy and promoting longevity. The methods, compounds, and compositions relate to urolithins and urolithin precursors and use thereof. Certain urolithins are represented by Formula I, while certain urolithin precursors are represented by Formula IV. The urolithin may be urolithin A, urolithin B, urolithin C, or urolithin D. The urolithin precursor may be ellagic acid or an ellagitannin. The methods include in vivo, ex vivo, and in vitro uses of the compounds and compositions.
1. A method of treating a disease or condition selected from the group consisting of sarcopenia, sarcopenia of aging, osteoarthritis, muscular atrophy, muscle disuse atrophy, skeletal muscular atrophy, cardiac deterioration, cardiac deterioration with aging, negative consequences linked to aging, improving activity during aging, reducing age-related cataracts, improving balance or coordination, and frailty, comprising administering to a subject in need thereof a therapeutically effective amount of a urolithin, or a pharmaceutically acceptable salt thereof.
2. The method of claim 1 , wherein the disease or condition is sarcopenia.
3. The method of claim 1 , wherein the disease or condition is sarcopenia of aging.
4. The method of claim 1 , wherein the disease or condition is osteoarthritis.
5. The method of claim 1 , wherein the disease or condition is muscular atrophy.
6. The method of claim 1 , wherein the disease or condition is muscle disuse atrophy.
7. The method of claim 1 , wherein the disease or condition is skeletal muscular atrophy.
8. The method of claim 1 , wherein the disease or condition is cardiac deterioration.
9. The method of claim 1 , wherein the disease or condition is cardiac deterioration of aging.
10. The method of claim 1 , wherein the disease or condition is negative consequences linked to aging.
11. The method of claim 1 , wherein the disease or condition is improving activity during aging.
12. The method of claim 1 , wherein the disease or condition is reducing age-related cataracts.
13. The method of claim 1 , wherein the disease or condition is improving balance or coordination.
14. The method of claim 1 , wherein the disease or condition is frailty.
15. The method of claim 1 , wherein the urolithin is administered orally.
16. The method of claim 1 , wherein the urolithin is selected from the group consisting of urolithin A, urolithin B, and any combination thereof.
17. The method of claim 1 , wherein the urolithin is urolithin A.
18. The method of claim 1 , wherein the urolithin is urolithin B.
19. The method of claim 1 , wherein the subject is a human.
20. The method of claim 1 , wherein the urolithin is administered orally; the urolithin is urolithin A; and the subject is a human.
