6'-Prenylisorhamnetin is primarily studied for its potential biological activities, particularly in the field of pharmacology and natural product research. It exhibits strong antioxidant properties, making it useful in protecting cells from oxidative stress and free radical damage. This compound has shown anti-inflammatory effects by inhibiting key inflammatory pathways, suggesting possible applications in managing chronic inflammatory diseases.

It also demonstrates anticancer potential through the induction of apoptosis and inhibition of cell proliferation in certain cancer cell lines. Research indicates activity against tumor growth in vitro, especially in breast and liver cancer models. Additionally, 6'-Prenylisorhamnetin has been investigated for its neuroprotective effects, with potential use in neurodegenerative disorders such as Alzheimer’s disease due to its ability to cross the blood-brain barrier and reduce neuronal damage.

Due to its natural origin and structural features, it is considered a lead compound in the development of nutraceuticals and functional foods aimed at promoting cellular health and preventing age-related diseases. It is also utilized in cosmetics and skincare for its antioxidant and anti-inflammatory benefits, protecting skin from environmental damage like UV radiation and pollution.
