Synthesis of methyl-substituted xanthotoxol to clarify prooxidant effect of methyl on radical-induced oxidation of DNA

4-Methyl-8-hydroxylpsoralen (MXan) and 4,9-dimethyl-8-hydroxylpsoralen (DMXan) were synthesized in order to clarify the effect of methyl on the antioxidant effectiveness of xanthotoxol (8-hydroxylpsoralen, Xan), which were assessed by bleaching β-carotene

8-Methoxypsoralen derivatives

The invention relates to synthetic processes to produce the known pharmacologically active 8-methoxypsoralen and derivatives thereof. Also disclosed are various novel intermediates utilized in these processes.
