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

Few studies have directly compared the clinical efficacy of psoralen plus ultraviolet A (PUVA) vs. biologics in the treatment of psoriasis. To compare the clinical efficacy of PUVA and biologic therapies for psoriasis under daily life conditions. Data from a
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

Ultraviolet (UV) A1 and psoralen plus UVA (PUVA) are effective treatment options for severe atopic dermatitis (AD); however, their relative efficacy has not yet been determined in a head-to-head study. To compare UVA1 and oral 5-methoxypsoralen (5-MOP) plus UVA with

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
