  Synthesis of a glucuronic acid and glucose conjugate library and evaluation of effects on endothelial cell growth

  摘要：

  Compounds that alter endothelial cell growth are of interest in the development of angiogenesis modulators. A structurally diverse series of saccharide derivatives (glycosylamide conjugates) have been synthesized and evaluated for their effects on bovine aortic endothelial cell (BAEC) growth. Heparin-albumin (HA) reduced BAEC growth by 32% at 10 mug/mL and a number of the novel saccharide conjugates from the library were found to mimic the effect of HA as they also inhibit endothelial cell survival under identical conditions. Two thiophene conjugates, thioglucamide (24% inhibition at 35 muM) and a related glucuronide (26% inhibition at 33 muM) were the most potent inhibitors of BAEC growth, as determined using a methylthiazol tetrazoliurn (MTT) assay. The effects of thioglucamide and HA on absolute cell number were also studied using cell counting experiments; thioglucamide (47% after 24 h) was more potent than indicated by the MTT assay and initially reduced the BAEC number to a greater extent than HA (30% after 24 h); however, its actions were over more rapidly than were HA's as cell growth had returned to levels of the control after 72 h where HA still caused 25% inhibition. The binding of the monosaccharide conjugates to fibroblast growth factor (FGF-2) in competition with heparin-alburnin by ELISA was investigated to establish the possible mechanism by which glycoconjugates could alter growth but there was no general correlation between reduction in viable cell population and binding to FGF-2. No glycoconjugate reduced the proliferation of mouse mammary epithelial cells, nor did any alter gross cell morphology, supporting a proposal that the reduction in BAEC survival by monosaccharide conjugates such as thioglucamide is a result of the inhibition of cell proliferation rather than being an induction of cytotoxicity. These studies indicate that cell biological studies to determine the mechanism of action of the simple monosaccharide conjugates may be worthwhile. (C) 2004 Elsevier Ltd. All rights reserved.

  Inhibitors of FGF-2 binding to a heparin-albumin conjugate were identified by ELISA from a library of glucuronic acid derivatives. These compounds were also inhibitors of endothelial cell survival that is dependant on FGF-2 and heparin or heparan sulfate proteoglycans. The results indicate that these bioactive compounds may prove useful as lead structures for the further development of pharmaceutical agents capable of modulating biological activity of FGF-2.
