丙型肝炎病毒(hepatitis C virus,HCV)是一种高度变异的正链RNA黄病毒,具有慢性转化率高、病变率高等特征。有研究表明,NS3/NS4A多功能蛋白酶是HCV复制所必须的,因而NS3/NS4A蛋白酶抑制剂在HCV治疗中的意义备受关注。替拉瑞韦(Telaprevir)是一种可逆的HCV NS3/NS4A蛋白酶抑制剂,动物试验和临床试验都表明它可以有效地直接攻击HCV并阻断其复制,对HCV的抑制作用持久,将成为丙型肝炎病毒的新型治疗药物。

[Abstract]
Hepatitis C virus (HCV) is a highly variable positive-strand RNA flavivirus, and has the characteristics of chronic high conversion and pathologic change. There are evidences shown that NS3/NS4A protease activity is essential for viral replication, thus the therapeutic significance of inhibiting the HCV protease NS3/NS4A has been widely concerned. Telaprevir, an ig administered, reversible, and peptidomimetic inhibitor of the HCV protease NS3/NS4A, has been proved to be effective for attacking HCV and breaking viral replication both in animal experiments and clinical trials. It is expected to become a new drug for treatment of HCV.
