Can Polyphenols Become Senotherapeutic Agents?
A natural flavonoid reveals new perspectives for targeting cellular senescence and age-related diseases
Cellular senescence is increasingly recognized as a major driver of aging, chronic inflammation and age-related diseases. A recent study published in Nature Communications suggests that a natural flavonoid could act directly on this fundamental biological process.
Researchers led by Professor Yu Sun identified dihydromyricetin as a natural compound with senotherapeutic potential. Rather than producing a single effect in every senescent cell, the flavonoid appeared to act differently depending on the cellular context.
In senescent fibroblasts, dihydromyricetin reduced the pro-inflammatory senescence-associated secretory phenotype and limited further DNA damage. The researchers linked this effect to peroxiredoxin 2, or PRDX2, which was transported into the nucleus and supported DNA-repair mechanisms. In this context, the compound acted primarily as a senomorphic agent, modifying the harmful behaviour of senescent cells without necessarily eliminating them.
In senescent microglial cells, however, dihydromyricetin impaired mitochondrial function and promoted apoptosis, producing a senolytic effect. In mouse models of Alzheimer’s disease, the treatment reduced senescent microglial cells around amyloid plaques and improved neurodegenerative outcomes.
The compound also reduced tissue-aging phenotypes in prematurely aged mice and improved the effects of chemotherapy in experimental cancer models. These findings position dihydromyricetin as a potential multifunctional senotherapeutic agent acting across DNA repair, inflammation, mitochondrial function and cellular survival.
The results remain preclinical and do not yet demonstrate that dihydromyricetin can prevent or treat age-related diseases in humans. Nevertheless, the study opens an important perspective for polyphenol research:
Could polyphenols be developed as precision agents that suppress, reprogram or selectively eliminate senescent cells?
This emerging direction will be discussed during Polyphenols Applications 2026, taking place on October 8–9, 2026, in Málaga, Spain, where researchers will explore how polyphenols are moving beyond their classical antioxidant role toward targeted applications in healthy aging and disease prevention.
