  Toward the Back-Up of Boceprevir (SCH 503034): Discovery of New Extended P₄-Capped Ketoamide Inhibitors of Hepatitis C Virus NS3 Serine Protease with Improved Potency and Pharmacokinetic Profiles

  摘要：

  Hepatitis C is the most prevalent liver disease. Viral hepatitis C (HCV), a small (+)-RNA virus, infects chronically an estimated 300 million people worldwide. Results of Phase I clinical studies with our first generation HCV inhibitor Boceprevir, SCH 503034 (1), presented at the 56th Annual Meeting of the American Association for the Study of Liver Diseases (AASLD) were encouraging, and thus, additional human clinical studies are underway. In view of the positive data from our first generation compound, further work aimed at optimizing its overall profile was undertaken. Herein, we report that extension of our earlier inhibitor to the P-4 pocket and optimization of the P-1' capping led to the discovery of new ketoamide inhibitors of the HCV NS3 serine protease with improved in vitro potency. In addition to being potent inhibitors of HCV subgenomic RNA replication, some of the new P-4-capped inhibitors were also found to have improved PK profile.

  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.

  HCV infection is considered a silent epidemic because most people infected do not develop acute symptoms. Instead, the disease progresses to a chronic state leading to cirrhosis and hepatocarcinoma. Novel therapies are needed to combat this major health threat. The HCV NS3 serine protease has been the target of continuous investigation because of its pivotal role in viral replication. Herein, we present the P1-P3 macrocyclization approach followed for identification of HCV NS3 inhibitors as potential back-up candidates to our first generation drug candidate, Sch 503034 (1). Different P1-P3 linkers were investigated to identify novel macrocyclic scaffolds. SAR exploration of P3-caps in the macrocyclic cores allowed the identification of L-serine derived macrocycle 32 (K-i* = 3 nM, EC90 = 30 nM) and allo-threonine derived macrocycle 36 (K-i* = 3 nM, EC90 = 30 nM) as potent HCV NS3 protease inhibitors.
