(-)-Arctigenin is primarily studied for its potential therapeutic applications in various fields of medicine. It exhibits anti-inflammatory properties, making it a candidate for treating inflammatory diseases such as arthritis and other chronic inflammatory conditions. Additionally, its antioxidant effects are being explored for their role in protecting cells from oxidative stress, which is linked to aging and various diseases, including neurodegenerative disorders like Alzheimer's.

In oncology, (-)-Arctigenin has shown promise in inhibiting the growth of certain cancer cells. Research suggests it may induce apoptosis (programmed cell death) in cancer cells and inhibit angiogenesis (the formation of new blood vessels that tumors need to grow), making it a potential adjunct in cancer therapy.

Furthermore, (-)-Arctigenin has been investigated for its antiviral properties, particularly against influenza and other viruses. Its ability to modulate the immune response and inhibit viral replication highlights its potential as a therapeutic agent in managing viral infections.

In metabolic health, studies indicate that (-)-Arctigenin may improve insulin sensitivity and reduce blood glucose levels, suggesting its utility in managing diabetes and related metabolic disorders.

Overall, (-)-Arctigenin is a compound of significant interest in medical research, with potential applications in treating inflammation, cancer, viral infections, and metabolic diseases.
