Biological Activity: Praeruptorin E is an orally active pyranocoumarin compound. Praeruptorin E can be isolated from the dried roots of Peucedanum praeruptorum Dunn. Praeruptorin E reduces the expression of NF-κB. Praeruptorin E upregulates the expression of PXR and CYP3A4. Praeruptorin E inhibits Th2 cytokines, TNF-α, IL6, MPO, and blocks the Ca2+ slow channel. Praeruptorin E promotes pulmonary tissue repair and relaxes porcine coronary artery strips. Praeruptorin E protects mice from lipopolysaccharide- and hydrochloric acid-induced acute lung injury. Praeruptorin E can be used in studies related to asthma and acute lung injury[1][2][3].
