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 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
5-Methoxypsoralen, a naturally occurring linear furocoumarin, has been successfully used in combination with ultraviolet (UV) A irradiation [psoralen plus UV (PUVA)] to manage psoriasis and vitiligo. In patients and volunteers, PUVA 5-methoxypsoralen causes a dose-related increase in cutaneous photosensitivity. However
The British journal of dermatology, 165(3), 640-645 (2011-05-14)
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
