  Synthesis and biological evaluation of glycosylated psoralen derivatives

  摘要：

  A novel route for the efficient synthesis of a target psoralen moiety, 4,4'-dimethylxanthotoxol, has been developed, which need only four steps using cheap pyrogallol as a starting material. Subsequently, a range of new glycosylated psoralen derivatives were synthesized in good yields with simple procedures and mild reaction conditions. The experiment of biological activity shows that some of the glycosylated psoralen derivatives have antiproliferative activities against human cancer cell lines. A strong photoinduced antiproliferative effects were found under UVA. All of the glycosylated psoralen derivatives exhibited antioxidant activities against the oxidation of DNA induced by Cu2+/glutathione (GSH). Further experiment also demonstrates that the introduction of sugar moieties in some glycosylated psoralen derivatives can improve their antioxidant activities significantly. (C) 2012 Elsevier Ltd.

  Abstract Reaction of 7,8-dihydroxy-2H-1-benzopyran-2-one, and its 4-methyl derivative, with α-haloketones affords α-pyrano-1,5-benzodioxapines, while 3-chloro-4-methyl-7,8-dihydroxy-2H-1-benzopyran-2-one gives α-pyrano-1,4-benzodioxane. The structures of the compounds were deduced using a combination of 1H nmr, 13C nmr (BB, DEPT), HETCOR, NOESY, and selective INEPT techniques and molecular modeling
