series of macrocyclic inhibitors of FXIa with oral bioavailability. Assisted by structure based drug design and ligand bound X-ray crystal structures, the group linking the P1 moiety to the macrocyclic core was modified with the goal of reducing H-bond donors to improve pharmacokinetic performance versus 9. This effort resulted in the discovery of several cyclic P1 linkers, exemplified by 10, that are constrained
该手稿描述了一系列具有口服生物利用度的FXIa大环抑制剂的发现。借助基于结构的药物设计和配体结合的X射线晶体结构,将P1部分连接至大环核心的基团经过修饰,目的是减少与9的H键供体,从而改善药代动力学性能。这项工作导致发现了几个环状的P1接头,以10为例,它们是9的丙烯酰胺接头所显示的生物活性构象的受限模拟物。这些环状P1接头显示出更高的生物利用度和更高的效能。
