(Malvaceae), Angelica archangelica, Angelica dahurica, Glehnia littoralis, Saposhnikovia divaricata, Cnidium monnieri, Incarvillea younghusbandii, and Zanthoxylum americanum mill. It is biosynthesized from umbelliferone, a coumarin derivative.
Isolation
The procedure for the isolation of imperatorin from Urena lobata involves exhaustively extracting under reflux with benzene the air-dried and pulverised roots followed by separation by column chromatography.
Biochemical activity
Imperatorin was identified from a Bioactive Molecules library in a high throughput screening experiment for inhibitors of the phosphodiesterase PDE4. It displays a significant preference for PDE4B over PDE4A. Imperatorin has been shown to have anti-inflammatory activity in chondrocytes. Imperatorin treatment inhibits the expression of iNOS and suppresses the production of NO in osteoarthritic chondrocytes.
