Biosynthesis of furanocoumarins in parsnips

Phytochemistry, 1970
Abstract Labelling experiments have shown that umbelliferone, and to a lesser degree p -coumaric acid, are precursors of bergapten, imperatorin, isopimpinellin and xanthotoxin in Pastinaca sativa L. C-2 and C-5 of mevalonate, which has been proposed as a precursor of two furan ring carbons and of dimethylallyl substituents, were both incorporated ...

Collective Synthesis of Furanocoumarin Natural Products Through a Radical‐mediated Construction of Furanocoumarin Skeletons

Asian Journal of Organic Chemistry
AbstractFuranocoumarins are attractive targets in the synthetic organic and medicinal chemistry field because of their structural diversity and interesting biological properties. Herein, we describe the synthesis of furanocoumarin natural products from common furanocoumarin skeletons.

The Role of Dihydropsoralen in Furanocoumarin Metabolism

Canadian Journal of Biochemistry, 1973
Trapping experiments with [2-14C]umbelliferone and 2′,3′-dihydropsoralen (DHP) administered to Ruta graveolens yielded negative results over metabolic periods of 5–24 h. Specific radioactivities of psoralen were comparable to those previously observed, but those of DHP were about two orders of magnitude lower.
