Fluorinated oligopeptides, especially those having 4,4-difluoro-2-amino butyric acid at the C terminus, may be effective inhibitors of hepatitis C virus NS3 protease. Examples of hexapeptides of the invention, optimized for binding in the S1 specificity pocket of the enzyme, may display IC
50
s at the sub-micromolar level. Embodiments of tripeptides of the invention, having a keto-acid group at the C-terminus are, likewise, potent inhibitors of NS3 protease.
氟化寡肽,特别是具有C端的4,4-二氟-2-氨基丁酸的寡肽,可能是乙型肝炎病毒NS3蛋白酶的有效抑制剂。该发明的六肽示例,经过优化以在酶的S1特异性口袋中结合,可能在亚微摩尔水平显示IC50。同样,该发明的三肽实施例,其C端具有酮酸基团,也是NS3蛋白酶的有效抑制剂。
