Optimization of macrocyclic inhibitors of FXIa is described which focused on modifications to both the macrocyclic linker and the P1 group. Increases in potency were discovered through interactions with a key hydrophobic region near the S1 prime pocket by substitution of the macrocyclic linker with small alkyl groups. Both the position of substitution and the absolute stereochemistry of the alkyl groups
描述了FXIa大环抑制剂的优化,其重点在于对大环接头和P1基团的修饰。通过用小烷基取代大环接头,与S1主口袋附近的关键疏水区相互作用,发现效能增强。大环连接基上烷基的取代位置和绝对立体化学(其导致改善的效力)均根据大环的环大小而变化。在这些优化的大环化合物中取代氯苯基四唑肉桂酰胺P1可以减少极性表面积并提高该系列产品的口服生物利用度,尽管以降低效力为代价。
