A Practical Synthesis of the Platelet Fibrinogen Antagonist, Elarofiban
摘要:
Elarofiban is a novel, nonpeptide, orally active fibrinogen receptor antagonist useful for the treatment of platelet mediated thrombotic disorders (Costanzo, M. J.; Hoekstra, W. J.; Maryanoff, B. E. WO, 97/41102,1997). Herein we describe the process research that was carried out for the synthesis of elarofiban that eventually led to the development of a safe and cost-effective commercial scale process.

intravenously administered antiplatelet fibrinogenreceptor (GPIIb/IIIa) antagonists have become established in the acute-care clinical setting for the prevention of thrombosis, orally administered drugs for chronic use are still under development. Herein, we present details from our exploration of structure-activity surrounding the prototype fibrinogenreceptorantagonist RWJ-50042 (racemate of 1), which
尽管在急性护理临床环境中已建立了静脉内施用的抗血小板纤维蛋白原受体(GPIIb / IIIa)拮抗剂,以预防血栓形成,但仍在开发用于长期使用的口服药物。在本文中,我们介绍了围绕原型纤维蛋白原受体拮抗剂RWJ-50042(外消旋体1)的结构活性探索的细节,该结构活性源自涉及纤维蛋白原γ链的独特方法(Hoekstra et al.J.Med。 1995,38,1582)。我们的模拟研究最终发现了有效的口服活性GPIIb / IIIa拮抗剂RWJ-53308(2)。为了从RWJ-50042逐渐发展成为适合临床开发的候选药物,我们进行了一系列优化周期,这些周期采用固相平行合成技术进行快速,有效制备了将近250种类似物,对它们的血纤维蛋白原受体亲和力和四种不同激活剂诱导的血小板聚集抑制进行了测定。该策略产生了一些有前途的有希望进行进一步研究的类似物,包括3-(3,4-亚甲二氧基苯)-β-氨基酸类
