Propriétés photosensibilisatrices des furocoumarines
Journal de Chimie Physique, 1980Les 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, 2002Furocoumarins (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, 1984Abstract 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
1994In 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

Photochemical Reactions of Furocoumarins
1982The recent line of research in the field of furocoumarins, de veloped for obtaining new agents able to photosensitize biological substrates only through monofunctional photolesions to DNA, is discussed. The interactions between a group of methylderivatives of angelicin, recently prepared, and DNA both in the ground and in the excited state are referred.

Photochemotherapy with Furocoumarins (Psoralens)
1982Photochemotherapy is the combined use of a photosensitizing chemical compound with non-ionizing electromagnetic radiation to bring about a therapeutically beneficial result not produced by the drug or radiation alone. The drug may be applied topically or administered systemically to reach the skin via the circulation and is subsequently activated by ...
