Prolongevity: New Evidence of Anti-Aging Effect of Resveratrol

For years, it has been known that resveratrol is one of the most effective anti-aging compounds studied. Beneficial effects on lifespan have been demonstrated across many research organisms, including worms and flies. In 2003, resveratrol was identified as a molecule which could activate SIRT1, mimicking the life extending benefits shown by calorie restriction. Furthermore, resveratrol also activates the anti-aging Nrf2 pathway, and AMPK which enhances NAD+ availability. (1) Cellular NAD+ levels are linked to longevity. 

In a new study, the silkworm was used to further illustrate the life extending effects of resveratrol via significant improvement of antioxidant activity.. Oxidation is a key factor is anti-aging and shortening of the lifespan.(2)

Resveratrol was shown to activate antioxidant function in the silkworm via increased activity of the GST enzyme, key in the antioxidant enzyme system.

  • SIRT7 (activation) ---> activates FOXO --> activates GST (antioxidant) 

This research further validates the beneficial life extending benefits of resveratrol.

Two times Power of Anti-Aging Resveratrol - Ursolic Acid and Rosmarinic Acid

Resveratrol has long been known as an natural anti-aging gene activator. The target of this activation is SIRT1. Research now indicates that another extract  (ursolic acid) is even more powerful than resveratrol in the activation SIRT1. Furthermore, the extracts ursolic acid and rosmarinic acid promote anti-aging in other ways,, including preservation of the functioning of the hypothalamus (implicated as playing a significant role in the aging process), inhibiting fibrosis (amyloid and tau) and inhibiting NOX2 and NOX4.

URSOLIC ACID

  • SIRT1 Activator - Ursolic acid is a powerful activator of anti-aging protein SIRT1. In fact, when compared to resveratol, ursolic acid is double the power of activating SIRT1 versus resveratol.(1)
  • Hypothalamus Anti-Aging - Recent research indicates that the hypothalamus is an important determinant in longevity, Dysregulation of the hypothalamus during aging affects the neuroendocrine system, and contributes to the exhaustion of stem cells, and the loss of proteostasis.(2) Ursolic acid beneficially supports health of the hypothalamus by enhancing levels of anti-aging SIRT1, SIRT6, PGC-1β and α-Klotho.(3)
  • Nrf2 Preservation - Nrf2 is the master protein activator of the endogenous antioxidant system in the body, and is related to increased longevity. Ursolic acid is a potent inhibitor of the degradation of Nrf2, which supports increased level of Nrf2. (4)

ROSMARINIC ACID

  • Longevity Extender -  In experimental studies with c. elegans, rosmarinic acid significantly extended lifespan by increasing anti-aging gene expression of daf-16 and other proteins.(5) 
  • NOX2 and NOX4 (NADPH oxidases) Inhibitor - NOX2 and NOX4 play critical roles in aging.
    • NOX2 - involved in hypertension, atherosclerosis, cardiac hypertrophy, diabetes and aging. The inhibition of NOX-2 is proposed for maintaining cardiovascular homeostasis.(6)
    • NOX4 - involved in cellular senescence. The inhibition of NOX-4 may support anti-aging in body, which is expressed in many organs in the body.(7)
  • Both NOXs are viewed as potential therapeutic targets to block.
  • Rosmarinic acid inhibits both NOX2 and NOX4.(7)
  • Amyoid Aggregation Inhibitor  -  An important hallmark of aging, both in the brain (Alzheimers Disease) and throughout the body, is the formation of amyloid fibril aggregates.
    • While resveratrol has been shown to be inactive in the inhibition of aggregate formation,  rosmarinic acid, is shown as a powerful inhibitor.(8)
  • Tau Aggregation Inhibitor - Insoluble tau protein is another protein abnormality (in conjunction with amyloid) associated with Alzheimer's Disease in the brain. Aging and chronic stress may induce tau aggregation. In lab animals, rosmarinic acid was shown to reduce tau protein aggregation. (9)
  • Glycation Inhibitor - Supports Elastic Arteries and Skin. Glycation is the damaging of protein structure, accelerating aging of all protein structures in the body. Includes loss of elasticity of skin and arterial function.
    • Glycation results in stiffness of the skin (and old appearance) and arteries. All indicators of significant aging. Rosmarinic acid was shown to improve the parameters of skin and arterial elasticity in human test subjects.(10)
  • Insulin Resistance - AMPK. Rosmarinic acid significantly reduced skeletal muscle insulin resistance in insulin resistant lab animals. Rosmarinic acid activated AMPK in the muscle, which resulted in increased mitochondrial biogenesis,(11)
