Beyond antitumor activity and from lichenized fungi: advances in the production, bioactivities, synthesis, and biosynthesis of usnic acid and its structural derivatives

Green Chemistry Letters and Reviews
Usnic acid and its structural derivatives are dibenzofuran natural products characterized by a distinctive 6-5-6 tricyclic scaffold. These compounds, isolated from lichenized fungi, non-lichenized fungi, and select higher plants, exhibit a broad spectrum
