Furocoumarins ofCnidium dubium

Chemistry of Natural Compounds, 1966
1. Paper chromatography has shown that the fruit ofC. dubium contains not less than eight substances of coumarinic nature; six of these (A, B, C, D, E, and H) have been isolated in the crystalline state. 2. Substances B, D, and E are identical with isoimperatorin, imperatorin, and oxypeucedanin, respectively.

Furocoumarins from Angelica pachycarpa

Phytochemistry, 1983
Abstract A novel furocoumarin isolated from unripe fruits of Angelica pachycarpa has been characterized as (+)-tert- O -methylbyakangelicin. (+)-tert- O -Methyloxypeucedanin hydrate, neobyakangelicol, (±)-byakangelicol, (+)-byakangelicin, phellopterin, isoimperatorin, oxypeucedanin, oxypeucedanin hydrate, pangeline and umbelliprenin were also ...

Photobiology of Furocoumarins

1982
The photobiology of fucoroumarins has been covered by a number of reviews (1–4). In recent years we observed a rapid evolution in the knowledge on naturally occurring or synthetic furocoumarins which in the presence of near ultraviolet light or UVA, i.e. radia tion in the range of 320 to 380 nm, exhibit photosensitizing properties in various biological

Propriétés photosensibilisatrices des furocoumarines

Journal de Chimie Physique, 1980
Les comportements photochimiques du methyl-4 psoralene (M-4-P) et du dihydro-4', 5' methyl-4 psoralene (DHM-4-P), en presence de bases pyrimidiques et de maleimides, ont ete etudies pour tenter de modeliser les reactions entre furocoumarines et ADN.

Furocoumarin photolysis: chemical and biological aspects

Photochemical & Photobiological Sciences, 2002
Furocoumarins (psoralens) undergo photolysis when subjected to UVA radiation in solution. Several products are formed, depending on the molecular structure and experimental conditions. Some products are the result of anoxic mechanisms (cyclodimerisation, addition of solvent), others of oxic pathways, leading to oxidised products. The mechanisms thought

ELECTROPHORETIC SEPARATION OF FUROCOUMARIN: DNA PHOTOADDUCTS

Photochemistry and Photobiology, 1984
Abstract We describe a new approach for quantitating furocoumarin adducts in DNA using enzymatic hydrolysis followed by resolution and recovery of the adduct molecules by electrophoresis on polyacrylamide tube gels. The resolution of this method approaches that of high pressure liquid chromatography but at a considerably lower cost.

Photoaddition by Furocoumarins

1994
In photobiology, the photoreactions involving the formation of C4-cyclobutane type adducts in DNA, such as the formation of pyrimidine dimers (Setlow and Carrier, 1966) by short wave UV radiation and the photoaddition of furocoumarins to pyrimidines in DNA (Musajo and Rodighiero, 1972; Hearst et al., 1984), have been of particular importance because of
