Imperatorin is a furocoumarin and a phytochemical that has been isolated from Urena lobata L. ( Malvaceae), Angelica archangelica, [1] Angelica dahurica, [2] Glehnia littoralis, [3] Saposhnikovia divaricata, [4] Cnidium monnieri, [5] Incarvillea younghusbandii, [6] and Zanthoxylum americanum mill. [7] It is biosynthesized from umbelliferone, a coumarin derivative. [8]
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. [9]
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. [10] Imperatorin has been shown to have anti-inflammatory activity in chondrocytes. [11] Imperatorin treatment inhibits the expression of iNOS and suppresses the production of NO in osteoarthritic chondrocytes. [11]
