Discovery and Structure−Activity Relationship of P1−P3 Ketoamide Derived Macrocyclic Inhibitors of Hepatitis C Virus NS3 Protease
摘要:
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.

A method of treating, preventing or ameliorating one or more symptoms associated with hepatitis C virus (HCV) in a patient in whom either the HCV is of Genotype 1 and/or the patient was previously treated with interferon and the previous interferon therapy was ineffective to treat the one or more symptoms associated with HCV, comprising administering to such a patient an effective amount of at least one compound of formulae I-XXVI of which the following structural formula is exemplary
or a pharmaceutically acceptable salt, solvate or ester thereof. Optional combined administration of said at least one compound with an interferon or pegylated interferon and/or ribaviron is also contemplated.
