Can caloric restriction mimetics delay the onset of age-related diseases?

Caloric restriction mimetics are compounds that mimic the effects of caloric restriction, a dietary intervention known to extend lifespan and delay the onset of age-related diseases in various organisms, including yeast, worms, flies, and mice. These compounds activate similar molecular pathways as caloric restriction, such as the sirtuin pathway, which is involved in regulating cellular metabolism, stress response, and aging.

How do caloric restriction mimetics work?

Caloric restriction mimetics work by activating specific cellular pathways that are involved in regulating aging and age-related diseases. One of the key pathways targeted by these compounds is the sirtuin pathway, which is known to play a crucial role in modulating lifespan and healthspan. Sirtuins are a family of proteins that regulate various cellular processes, including DNA repair, gene expression, and metabolism. By activating sirtuins, caloric restriction mimetics can enhance cellular stress resistance, improve mitochondrial function, and promote overall health.

Examples of caloric restriction mimetics

There are several compounds that have been identified as caloric restriction mimetics, including:

• Resveratrol: Found in red wine, grapes, and certain berries, resveratrol has been shown to activate sirtuins and extend lifespan in various organisms.
• Metformin: A commonly used drug for treating type 2 diabetes, metformin has also been found to activate sirtuins and exhibit potential anti-aging effects.
• Rapamycin: Originally developed as an immunosuppressant drug, rapamycin has been shown to extend lifespan and delay age-related diseases in various organisms.
