  Effects of oxygen–sulfur substitution on glycosaminoglycan-priming naphthoxylosides

  摘要：

  Three series of sulfur-containing analogs to the selectively antiproliferative 2-(6-hydroxynaphthyl) beta-D-xylopyranoside were synthesized and their biological properties investigated. A short, general route to hydroxynaphthyl disulfides from dihydroxy-naphthalenes was developed to utilize the disulfide bond as a sulfur-selective protecting group to enable the orthogonal protection of hydroxyls and thiols. The results indicate that hydrophobic, uncharged oxygen-sulfur substituted naphthoxylosides are taken up by calls and initiate priming of GAG chains to a greater extent compared to the oxygen analogs. No correlation between priming ability and antiproliferative activity was observed. (c) 2007 Elsevier Ltd. All rights reserved.
