Judicious modifications to the structure of the previously reported HCV NS5A inhibitor 1, resulted in more potent anti-HCV compounds with similar and in some cases improved toxicity profiles. The synthesis of 19 new NS5A inhibitors is reported along with their ability to block HCV replication in an HCV 1b replicon system. For the most potent compounds chemical stability, stability in liver microsomes and inhibition of relevant CYP450 enzymes is also presented.
对先前报道的 HCV NS5A 抑制剂 1 的结构进行合理修饰,得到了更有效的抗 HCV 化合物,其毒性谱相似,在某些情况下有所改善。本文报道了 19 种新型 NS5A 抑制剂的合成及其在 HCV 1b 复制子系统中抑制 HCV 复制的能力。对于最有效的化合物,还介绍了其化学稳定性、在肝微粒体中的稳定性和对相关 CYP450 酶的抑制作用。
