Dunnianol is primarily used in research settings for its potential neuroprotective properties. It has shown promise in studies related to oxidative stress reduction in neuronal cells, making it a compound of interest in the development of treatments for neurodegenerative conditions such as Alzheimer's and Parkinson's diseases. Its ability to modulate cellular antioxidant pathways also supports its investigation in anti-aging formulations and cognitive health supplements. Additionally, dunnianol is utilized as a reference standard in analytical chemistry for identifying structurally similar natural products. Ongoing research explores its anti-inflammatory effects, particularly in models of chronic inflammation and immune response regulation.
