Furanocoumarins in anticancer therapy – For and against

Fìtoterapìâ, 2020
Furanocoumarins are a class of natural compounds produced by several plants, including those consumed by humans. They have been used medicinally in eastern countries for ages. Given the growing body of evidence about their anticancer potential and observations that naturally occurring compounds potentiate the antitumor activity of chemotherapeutics ...

Biosynthesis of linear furanocoumarins

Canadian Journal of Biochemistry, 1970
Labelling experiments with 14C and 3H have shown that linear furanocoumarins of Ammi majus, Angelica archangelica, Heracleum lanatum (Umbelliferae), and Ruta graveolens (Rutaceae) are formed from umbelliferone via the dihydrofuranocoumarin, marmesin.

Furanocoumarins from Dorstenia gigas

Phytochemistry, 2001
A series of linear and angular prenylated furanocoumarins and a benzofuran derivative were isolated from leaves and twigs of Dorstenia gigas (Moraceae), a plant occurring endemically on Socotra Island (Yemen). The structures were elucidated by spectroscopic methods (NMR, MS, UV) and chemical derivatization.

O-methyltransferases of furanocoumarin biosynthesis

Archives of Biochemistry and Biophysics, 1978
Extracts of the furanocoumarin-synthesizing plants, Ruta graveolens L. and Heracleum lanatum Michx., contain a soluble O-methyltransferase system mediating the methylation of the 5- and 8-hydroxyls of linear furanocoumarins by S-adenosyl- l -methionine.
