have disclosed a novel class of P2–P4 macrocyclic inhibitors of NS3/4A protease containing a carbamate functionality as capping group at the P3 N-terminus. Herein we report our work aimed at further depeptidizing the P3 region by replacement of the urethane function with a succinamide motif. This peptidomimetic approach has led to the discovery of novel P2–P4 macrocyclic inhibitors of HCV NS3/4A protease
丙型肝炎代表着严重的全球卫生保健问题。最近,我们公开了一类新的NS3 / 4A蛋白酶的P2-P4大环抑制剂,其在P3 N端含有一个氨基甲酸酯官能团作为封端基团。本文中,我们报告了我们的工作,旨在通过用琥珀酰胺基序取代氨基甲酸酯功能来进一步使P3区去肽化。这种拟肽方法已导致发现具有亚纳摩尔酶亲和力的HCV NS3 / 4A蛋白酶的新型P2-P4大环抑制剂。除了是有效的HCV亚基因组复制抑制剂外,该系列中的优化类似物还具有诱人的PK特性,并在口服后在大鼠中显示出令人鼓舞的肝脏水平。
