Biological Activity

[Description]:

(-)-Praeruptorin A is a nature product that could be isolated from the roots of Peucedanum praeruptorum Dunn. (-)-Praeruptorin A relaxes ileum and tracheal smooth muscles by activating NO/cGMP signaling pathway. (-)-Praeruptorin A has dramatically therapeutic effects on hypertension mainly through acting as a Ca2+-influx blocker[1].
