elements optimized within the pyrazinone series of thrombin inhibitors, were utilized to transform a weak triazolopyrimidine lead into a series of potent oxazolopyridines. A modification intended to attenuate plasma protein binding (i.e., conversion of the P3 pyridine to a piperidine) conferred significant factor Xa activity to this series. Ultimately, these dual thrombin/factor Xa inhibitors demonstrated
凝血酶抑制剂X射线晶体结构与在吡嗪酮系列凝血酶抑制剂中优化的结合元件的安装结合,可用于将弱的三唑并嘧啶铅转化为一系列有效的恶唑烷吡啶。旨在减弱血浆蛋白结合的修饰(即,P3吡啶向哌啶的转化)赋予该系列显着的因子Xa活性。最终,这些双重凝血酶/因子Xa抑制剂表现出出色的体外和体内抗凝功效。
