Brevilin A can be used using a selective extraction method to obtain natural substances, and can also be applied to prepare derivatives to use for anti-cancer activity.

This naturally occurring sesquiterpenoid (FW = 346.40 g/mol; CAS 16503- 32-5) from the volatile oils of the plant Centipeda minima inhibits (IC50 = 10 μg/mL) STAT3 phosphorylation in the Jak/STAT signal transduction pathway of A549R cells. Brevilin A showed high specificity on Janus Kinase activity and following STAT3 signaling without directly affecting some other signals, including p65, AKT and GSK-3β phosphorylation, as well as Src kinase activity. Brevilin A is also an antibiotic with activity against Giardia (IC50 = 16 μM) and Entamoeba histolitica (IC50 = 4–9 μM).
