The voltage-gated potassium channel Kv1.3 constitutes an attractive pharmacological target for the treatment of effector memory T cell-mediated autoimmune diseases such as multiple sclerosis and psoriasis. Using 5-methoxypsoralen (5-MOP, 1), a compound isolated from Ruta graveolens, as a template we
The in vitro antiproliferative activity and in vivo phototoxicity of some methyl derivatives of 5-methoxypsoralen and 5-methoxyangelicin, i.e. 4,4'-dimethyl-5-methoxyangelicin (compound I), 3,4'-dimethyl-5-methoxyangelicin (compound II), 4,4'-dimethyl-5-methoxypsoralen (compound III); and 3,4'-dimethyl-5-methoxypsoralen (compound IV), have been investigated. The effects of the compounds were

The biotransformation of bergapten (1) by the fungus Glomerella cingulata gave the corresponding reduced acid, 6,7-furano-5-methoxy hydrocoumaric acid (2), a new compound. Xanthotoxin (3) was also converted to the corresponding reduced acid cnidiol b (4) and demethylated metabolite xanthotoxol (5)

A sensitive, specific and rapid liquid chromatography-mass spectrometry (LC-MS) method has been developed and validated for the simultaneous determination of xanthotoxin (8-methoxypsoralen), psoralen, isoimpinellin (5,8-dimethoxypsoralen) and bergapten (5-methoxypsoralen) in rat plasma using pimpinellin as an internal standard (IS). The plasma
Upon UV photoactivation, psoralen analogs form covalent mono-adducts and cross-links with DNA at thymine residues. Electrospray ionization mass spectrometric analysis allowed rapid and efficient determination of the reaction percentages of each psoralen analog with DNA duplexes containing different binding sites
