  Synthesis and biological activity of oligomer-model compounds containing units of a key platelet-binding disaccharide of heparin

  摘要：

  A key disaccharide unit in heparin, O-(2-deoxy-2-sulfamido-6-O-sulfo-alpha-D-glucopyranosyl)-(1-->4)-2-O-sulfo-alpha-L-idopyranosyluronic acid, was previously found to be responsible for the binding interaction of heparin to platelets. A clustering effect to enhance the binding was found to be dependent on the number and frequency of the disaccharide units in a heparin molecule. To systematically examine the clustering effect, three oligomer-model compounds containing two or three units of the disaccharide were synthesized. These compounds inhibited (3)H-Iabelled heparin binding to human platelets more strongly than a compound containing only one unit of the disaccharide, (C) 1999 Elsevier Science Ltd.

  structure glycol-split uronic acid moieties probably responsible for their strong inhibitory activity. We describe here the total chemical synthesis of the trisaccharide GlcNS6S-GlcA-1,6anGlcNS (1) and its glycol-split (gs) counterpart GlcNS6S-gsGlcA-1,6anGlcNS (2) from glucose. As expected, in a heparanase inhibition assay, compound 2 is one order of magnitude more potent than 1. Using molecular modeling

  乙酰肝素酶是唯一已知的能够裂解硫酸乙酰肝素的内切糖苷酶。Roneparstat和necuparanib是从肝素中获得的乙酰肝素酶抑制剂，目前正在人类中作为潜在的抗癌药物进行测试，其结构中含有乙二醇分裂的糖醛酸部分，可能是其强大的抑制活性。我们在这里描述了三糖GlcNS6S-GlcA-1,6anGlcNS（1）及其乙二醇拆分（gs）对应物GlcNS6S-gsGlcA-1,6anGlcNS（2）的总化学合成。不出所料，在乙酰肝素酶抑制试验中，化合物2的效力比1高一个数量级。使用分子建模技术，我们创建了1和2的3D模型，并已通过NOESY NMR实验验证。纯合成寡糖已使乙二醇拆分的葡萄糖醛酸的构象得以首次深入研究。以1的结构引入乙二醇拆分单元可增加构象柔韧性，并缩短两种氨基葡萄糖动机之间的距离，从而促进与乙酰肝素酶的相互作用。然而，通过比较2和ronparstat的相对活性，我们可以得出结论，乙
