  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.

  Improved synthesis, X-ray structure, and antifungal activity of a sugar-psoralen conjugate: 4,4′-Dimethylxanthotoxol 2,3,4,6-tetra-O-Acetyl-β-D-glucoside

  摘要：

  An improved synthesis for 4,4 '-dimethylxanthotoxol 2,3,4,6-tetra-O-acetyl-beta-D-glucoside (1) starting from resorcinol was developed. Crystallographic analysis of glucoside 1 indicated that the dihedral angles between the mean planes of the tricyclic ring system of adjacent molecules was 54.820(22)degrees probably due to the steric hindrance caused by the bulky O-glucoside moiety, which prevents the molecules from packing via pi center dot center dot center dot pi stacking between the tricyclic cores. The antifungal screening data revealed that glucoside 1 had higher inhibition than its parent compound 4,4 '-dimethylxanthotoxol and azoxystrobin against Rhizoctonia solani, Pyricularia grisea, and Alternaria alternate Japanese pear pathotype, with the inhibitory rates of 75.4, 65.7 and 70.1%, respectively, at the 50 mu g/mL concentration.[GRAPHICS].

• 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-dimethy1-8-hydroxylpsoralen (DMXan) were synthesized in order to clarify the effect of methyl on the antioxidant effectiveness of xanthotoxol (8-hydroxyl-psoralen, Xan), which were assessed by bleaching beta-carotene in linoleic acid-Triton emulsion, by interacting with 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonate) cationic radical (ABTS(+))center dot, 2,2'-dipheny1-1-picrylhydrazyl radical (DPPH), and galvinoxyl radical, and by protecting DNA against the oxidation induced by Cu(2+)/glutathione (GSH) and 2,2'-azobis(2-amidinopropane hydrochloride) (AAPH). Methyl attaching to xanthotoxol did not affect its ability to protect linoleic acid against autoxidation and to inhibit Cu(2+)/GSH-induced oxidation DNA, but decreased its ability to scavenge ABTS(+)center dot and DPPH, and to protect DNA against AAPH-induced oxidation. Therefore, methyl attenuated the antioxidant effectiveness of xanthotoxol in radical-induced oxidation of DNA.
