A new class of hepatitis C NS3/4A inhibitors was identified by introducing a novel spirocyclic proline–P2 surrogate onto the P2–P4 macrocyclic core of MK-5172 (grazoprevir). The potency profile of new analogues showed excellent pan-genotypic activity for most compounds. The potency evaluation included the most difficult genotype 3a (EC50 values ≤10 nM) and other key genotype 1b mutants. Molecular modeling
通过在MK-5172(grazoprevir)的P2-P4大环核心上引入新的螺环脯氨酸-P2替代物,鉴定出一类新型的丙型肝炎NS3 / 4A抑制剂。对于大多数化合物,新类似物的效能曲线显示了出色的泛基因型活性。效能评估包括最困难的基因型3a(EC 50值≤10nM)和其他关键基因型1b突变体。分子建模被用来设计新的目标化合物并合理化我们的结果。还提出了一种基于Julia-Kocienski烯烃化和大内酰胺化的合成方法,以组装含有新型螺环脯氨酸-P2部分的P2-P4大环核。
