Novel conjugates of glycosaminoglycans, particularly heparin and dermatan sulfate, and amine containing species and therapeutic uses thereof are described. In particular, mild methods of conjugating heparins to proteins, such as antithrombin III and heparin cofactor II, which provide covalent conjugates which retain maximal biological activity are described. Uses of these conjugates to prevent thrombogenesis, in particular in lung airways, such as found in infant and adult respiratory distress syndrome, and on surfaces in contact with blood are also described.
本文介绍了糖胺聚糖(特别是
肝素和
硫酸真皮素)与含胺物质的新型共轭物及其治疗用途。特别是描述了将
肝素与蛋白质(如抗凝血酶 III 和
肝素辅助因子 II)共轭的温和方法,这种方法可提供保持最大
生物活性的共价共轭物。还介绍了这些共轭物在防止血栓形成方面的用途,特别是在肺部呼吸道(如在婴儿和成人呼吸窘迫综合症中发现的肺部呼吸道)和与血液接触的表面上。
