Abstract: Novel terpene hydroquinones have been isolated from the marine sponge Strongylophora hartmanii. These compounds have been found to have antiviral and anti-leukemia activity. Thus, these compounds, and derivatives thereof, can be used to treat human and animal leukemia as well as viral infections. Additionally, the subject invention concerns the discovery that the terpene hydroquinone known as aureol has strong antiviral activity.
