(-)-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.
Pd-C-II has anti-inflammation activity, it can inhibit TNF-α production and iNOS protein expression and inhibit COX-2 protein expression in LPS-stimulated RAW 264.7 cells. Pd-C-II inhibits anaphylactic mediator release from purified mast cells induced by
