    摘要:
    自 2011 年第一个获批的丙型肝炎病毒 (HCV) NS3 蛋白酶抑制剂以来,许多直接作用抗病毒药物 (DAA) 已进入临床试验后期。今天,有几种基于不同 DAA 的联合疗法,无论是否需要注射聚乙二醇化干扰素-α,均可用于慢性 HCV 感染。已获批准的和晚期 HCV NS3 蛋白酶抑制剂的化学基础明显相似。这可以部分解释在 NS3 蛋白酶抑制剂的压力下出现的交叉耐药性。开发的第一代 NS3 蛋白酶抑制剂可有效抑制病毒的基因型 1,而对其他基因型的抑制作用较弱。 本论文的主要重点是设计和合成一类新的基于 2(1H)-吡嗪酮的 HCV NS3 蛋白酶抑制剂,在结构上与临床试验中评估或批准的抑制剂不同,可能具有独特的耐药性和广泛的基因型覆盖范围。围绕吡嗪酮核心结构依次进行修饰,阐明构效关系;发现 P3 尿素封端基团对抑制效力有价值,延长的 R6 残基可能指向 S2 口袋。与先前开发的抑制剂不同,P1'

    HCV NS3 protease inhibitors and show that elongated R3 urea substituents were associated with increased inhibitory potencies over several NS3 protein variants. The inhibitors are believed to rely on β-sheet mimicking hydrogen bonds which are similar over different genotypes and current drug resistant variants and correspond to the β-sheet interactions of the natural peptide substrate.

  • Potent ketoamide inhibitors of HCV NS3 protease derived from quaternized P1 groups

    Blood borne hepatitis C infections are the primary cause for liver cirrhosis and hepatocellular carcinoma. HCV NS3 protease, a pivotal enzyme in the replication cycle of HCV virus has been the primary target for development of new drug candidates. Boceprevir and telaprevir are two novel ketoamide derived inhibitors that are currently undergoing phase-III clinical trials. These inhibitors include ketoamide functionality as serine trap and have an acidic alpha-ketoamide center that undergoes epimerization under physiological conditions. Our initial attempts to arrest this epimerization by introducing quaternary amino acids at P-1 had resulted in significantly diminished activity. In this manuscript we describe alpha quaternized P-1 group that result in potent inhibitors in the enzyme assay and demonstrate cellular activity comparable to boceprevir. (C) 2010 Elsevier Ltd.

    Hepatitis C virus (HCV) infection is the major cause of chronic liver disease, leading to cirrhosis and hepatocellular carcinoma, and affects more than 200 million people worldwide. Although combination therapy of interferon-alpha and ribavirin is reasonably successful in treating majority of genotypes, its efficacy against the predominant genotype (genotype 1) is moderate at best, with only about 40% of the patients showing sustained virological response. Herein, the SAR leading to the discovery of a series of ketoamide derived P-1-P-3 macrocyclic inhibitors that are more potent than the first generation clinical candidate, boceprevir (1, Sch 503034), is discussed. The optimization of these macrocyclic inhibitors identified a P-3 imide capped analogue 52 that was 20 times more potent than 1 and demonstrated good oral pharmacokinetics in rats. X-ray structure of 52 bound to NS3 protease and biological data are also discussed.
