Fondaparinux, a synthetic pentasaccharide anticoagulant based on heparin antithrombin-binding domain, is derived from a chemical synthesis with more than 50 steps. Herein, we identified nine analogues separated from commercially available crude fondaparinux sodium, and tested their anticoagulant activity in vitro. Based on the activity results, the most active derivative Rrt1.17 was chemically synthesized
Fondaparinux是一种基于肝素抗凝血酶结合域的合成五糖抗凝剂,是通过50多个步骤进行化学合成而得。本文中,我们从市售粗制磺达肝素钠中分离出9种类似物,并在体外测试了它们的抗凝活性。根据活性结果,化学合成了活性最高的衍生物Rrt1.17。体外和体内生物学特性表明,与磺达肝癸钠相比,定义明确的衍生物Rrt1.17是更有效的抗凝候选药物。
