Geroprotectors, also known as anti-aging compounds or longevity enhancers, have garnered significant attention in recent years due to their potential to promote healthy aging. These compounds hold promise in extending the human lifespan and improving overall well-being. In this comprehensive article, we will delve into the mechanisms of geroprotectors, explore their presence in various sources, and examine the specific functions of several prominent geroprotectors, including hydroxytyrosol, genistein, glucosamine, catechins, quercetin, caffeic acid, creatine, curcumin, myricetin, naringenin, nicotinamide, oleanolic acid, pinitol, proanthocyanidins, proline, rosemary acid, serine, silymarin, theanine, urolithin A, ursolic acid, physitin, fucoxanthin, fumaric acid, chicoric acid, and oxalic acetic acid.

Theories of geroprotectors and aging

Understanding the theories of aging is crucial in the development and application of geroprotectors. Several theories have been proposed to explain the complex process of aging, including the oxidative stress theory, inflammation theory, mitochondrial dysfunction theory, and telomere shortening theory.

1. The Oxidative stress theory

The oxidative stress theory suggests that accumulated oxidative damage to cells and tissues over time contributes to aging. Geroprotectors with antioxidant properties, such as hydroxytyrosol, quercetin, and curcumin, aim to counteract oxidative stress and protect against age-related damage.

2. The inflammation theory

The inflammation theory suggests that chronic inflammation plays a significant role in aging and age-related diseases. Geroprotectors with anti-inflammatory properties, such as catechins, silymarin, and rosmarinic acid, aim to mitigate chronic inflammation and promote healthy aging.

3. The mitochondrial dysfunction theory

The mitochondrial dysfunction theory suggests that age-related decline in mitochondrial function contributes to aging. Geroprotectors like urolithin A and fucoxanthin target mitochondrial health and promote cellular energy metabolism.

4. The telomere shortening theory

The telomere shortening theory proposes that the progressive shortening of telomeres, the protective caps at the end of chromosomes, leads to cellular senescence and aging. Geroprotectors such as physetin and ursolic acid may modulate cellular senescence and delay age-related decline.

These theories provide valuable insights into the mechanisms of aging and guide the development of geroprotectors that target specific aspects of the aging process.

What categories of geroprotectors exist?

Geroprotectors can be categorized based on their mechanisms of action and the biological processes they target. While geroprotectors are diverse in nature, they can be broadly classified into the following categories:

Natural geroprotectors also offer the potential for additional health benefits beyond their geroprotective properties, as many of these compounds have been traditionally used for various therapeutic purposes.

Synthetic Geroprotectors

Synthetic geroprotectors are developed through chemical synthesis in a laboratory setting. These compounds are designed to mimic the structure and function of natural geroprotectors or to exhibit unique properties not found in nature. Synthetic geroprotectors can be created by modifying existing natural compounds or by designing entirely novel molecules with specific geroprotective properties.

Synthetic geroprotectors offer advantages such as precise control over the chemical structure, purity, and dosage of the compound. They can be optimized for enhanced efficacy, stability, and bioavailability. Synthetic geroprotectors also provide the opportunity for structure-activity relationship studies, allowing scientists to explore the effects of different modifications on geroprotective activity.

However, synthetic geroprotectors may also raise concerns regarding their safety, potential side effects, and long-term effects on the body. Extensive testing and regulatory oversight are essential to ensure their safety and efficacy before they can be used in clinical applications.

Effectiveness of both of them

It’s worth noting that the distinction between natural and synthetic geroprotectors is not always clear-cut, as some natural compounds may undergo modifications or be produced synthetically for consistency and potency. Additionally, researchers are increasingly exploring the potential of combining natural and synthetic approaches to develop novel geroprotectors with optimized properties.

Both natural and synthetic geroprotectors have their place in research and development, offering unique opportunities and challenges. Continued exploration and understanding of these geroprotective compounds, regardless of their origin, will contribute to our knowledge of healthy aging and the development of interventions for promoting longevity and well-being.
