(-)-Praeruptorin A has anti-inflammatory, anti-contractile and anti-hyperplasia activities, it exerts distinct relaxant effects on isolated rat aorta rings dependent on endothelium and nitric oxide synthesis;it also can significantly suppress airway inflammation and airway remodeling induced by ovalbumin challenge, and is a potential candidate for the treatment of asthma. (-)-Praeruptorin A resensitizes Pgp-mediated MDR (Pgp-MDR) cancer cells to cancer drugs.
Jatrophane 5 demonstrates the most powerful inhibition of P-gp, higher than R(+)-verapamil and tariquidar in colorectal multi-drug resistant (MDR) cells (DLD1-TxR).
Lappaol C has antioxidant and antiaging properties, it may promote the C. elegans longevity and stress resistance through a JNK-1-DAF-16 cascade. Lappaol C also has potential chemosensitizing activity, it may be candidates for developing novel adjuvant an
