Wellness Biohacking: Researchers from the Daegu Gyeongbuk Institute of Science and Technology and Glaceum Incorporation in South Korea have discovered that a compound called vutiglabridin can protect human liver cells from aging-related damage. The study reveals that this compound works by targeting a special enzyme called paraoxonase 2 (PON2), which helps maintain healthy mitochondria—the tiny energy factories inside cells that are vital for life.
In simple terms, mitochondria produce the energy our cells need, but as we age or face stress, they get damaged by reactive oxygen species (ROS)—harmful molecules that cause oxidative stress. Over time, this stress triggers a process called cellular senescence, where cells stop dividing and begin to malfunction. According to this Wellness Biohacking new report, the South Korean scientists found that vutiglabridin activates PON2 to prevent this deterioration, helping cells stay younger and healthier.

How Vutiglabridin Works
Vutiglabridin (HSG4112) is an experimental anti-obesity drug that is a synthetic structural analog of glabridin. The researchers exposed liver cells (called LO2 hepatocytes) to hydrogen peroxide to mimic oxidative stress. This chemical causes cells to age faster by increasing ROS levels. After treatment, the scientists observed higher levels of aging markers known as p16 and p21, which indicate cellular damage. When vutiglabridin was added, these harmful effects were greatly reduced.
The study found that vutiglabridin decreased both p16 and p21 levels in a dose-dependent manner—meaning the more vutiglabridin was used, the stronger its protective effect. Under advanced microscopes, the treated cells maintained healthier mitochondrial structures with fewer breaks and less swelling, while untreated cells showed major damage.
Most importantly, when the same tests were performed on cells genetically engineered to lack the PON2 enzyme, vutiglabridin lost all of its protective benefits. This proved that PON2 is essential for the compound’s anti-aging effect.
Restoring Cellular Energy and Preventing Aging
The scientists observed that vutiglabridin not only lowered oxidative stress but also restored mitochondrial integrity—helping cells regain normal energy production and structure. In untreated cells, mitochondria became small, misshaped, and fragmented, but with vutiglabridin treatment, they stayed connected and functional. This suggests that the compound might interrupt the dangerous cycle between ROS buildup and mitochondrial damage that accelerates aging.
Why the Findings Matter
Aging is driven by a gradual accumulation of damaged and non-functioning cells, leading to inflammation and chronic diseases such as diabetes, cardiovascular problems, and neurodegeneration. By targeting PON2, vutiglabridin offers a promising new approach to maintaining cell health and delaying these age-related changes. The findings highlight that protecting mitochondria could be one of the keys to extending cellular lifespan and preventing degenerative diseases.
Conclusion
The researchers conclude that vutiglabridin works by preserving mitochondrial structure and controlling redox balance through the PON2 pathway. This discovery could pave the way for future anti-aging drugs that focus on cellular energy repair rather than just treating aging symptoms. Such therapies may one day help reduce age-linked tissue decline and improve overall longevity by maintaining mitochondrial health.
The study findings were published in the peer reviewed journal: Antioxidants.
