Imperatorin
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]
gollark: Nginx has a geoIP module.
gollark: Or just approximate the brain so it can be computed more easily without losing too much accuracy.
gollark: Well, the brain part is harder, but if you can work out the brain's I/O enough, that can just be simulated in detail and the rest to... really accurate computer game level.
gollark: I mean that just for a human-livable environment you don't need to actually simulate, say, particle interactions, at all.
gollark: You don't need to simulate things *exactly*, which helps.
