animal models of venous thrombosis. We describe here the preparation and the pharmacological properties of 34, an analogue of oligosaccharide 1 with the latter's N-sulfates being replaced by sulfate esters and hydroxyl groups being methylated. These structural modifications allow a simpler and more efficient synthesis of such anionic oligosaccharides. Affinity for human AT III, anti-factor Xa activity, ability
对应于肝素序列的合成五糖(1)与抗凝血酶III(AT III)结合并激活,在几种静脉血栓形成动物模型中都是有效的抗血栓形成化合物。我们在这里描述了寡糖1的类似物34的制备及其药理特性,寡糖1的N-硫酸盐被硫酸酯取代,羟基被甲基化。这些结构修饰允许更简单和更有效地合成这种阴离子寡糖。已针对1和34确定了与人AT III的亲和力,抗因子Xa活性,抑制凝血酶生成的能力,在静脉血栓形成的大鼠模型中的抗血栓形成活性以及在大鼠中消除半衰期的方法。硫酸盐代替N-硫酸盐,以及羟基的甲基化,
