Abstract
The bacterial natural product UK-1 and several structural analogs inhibit replication of the hepatitis C virus in the replicon assay, with IC50 values as low as 0.50 μM. The NS3 helicase has been identified as a possible target of inhibition for several of these compounds, while the remaining inhibitors act via an undetermined mechanism. Gel shift assays suggest that helicase inhibition is a direct result of inhibitor-enzyme binding as opposed to direct RNA binding, and the ATPase activity of NS3 is not affected. The syntheses and biological results are presented herein.
摘要
细菌天然产物 UK-1 和几种结构类似物在复制子测定中抑制丙型肝炎病毒的复制，其 IC50 值低至 0.50 μM。已鉴定出 NS3 解旋酶是这些化合物中几种可能的抑制靶标，而其余抑制剂则通过未知机制发挥作用。凝胶迁移分析表明，解旋酶抑制是抑制剂-酶结合的直接结果，而不是直接的 RNA 结合，并且 NS3 的 ATP 酶活性不受影响。本文介绍了它们的合成和生物学结果。
