A novel series of macrocyclic FXIa inhibitors was designed based on our lead acyclic phenyl imidazole chemotype. Our initial macrocycles, which were double-digit nanomolar FXIa inhibitors, were further optimized with assistance from utilization of structure-based drug design and ligand bound X-ray crystal structures. This effort resulted in the discovery of a macrocyclic amide linker which was found
基于我们的无环苯基咪唑基化学型,设计了一系列新的大环FXIa抑制剂。我们最初的大环化合物是两位数纳摩尔的FXIa抑制剂,在利用基于结构的药物设计和结合配体的X射线晶体结构的帮助下,得到了进一步的优化。这项工作导致发现了大环酰胺接头,该接头被发现与FXIa活性位点的Leu41的羰基形成关键的氢键,从而产生有效的FXIa抑制剂。以化合物16为例的大环FXIa系列的FXIa K i = 0.16 nM,在体外凝血试验中具有强大的抗凝活性(aPTT EC 1.5x = 0.27μM)和对相关血液凝结酶的优异选择性。
