It exhibits antiviral activity against SARS-CoV-2. It has a role as a T-cell proliferation inhibitor, an anti-inflammatory agent, a plant metabolite, an EC 3.4.22.69 (SARS coronavirus main proteinase) inhibitor and an anticoronaviral agent. It is a member of benzodioxoles, a lignan and a gamma-lactone."}]
