Definitions

  • HCV Hepatitis C virus
  • Flaviviridae family has closest relationship to the pestiviruses that include hog cholera virus and bovine viral diarrhea virus (BVDV).
  • BVDV bovine viral diarrhea virus
  • HCV is believed to replicate through the production of a complementary negative-strand RNA template. Due to the lack of efficient culture replication system for the virus, HCV particles were isolated from pooled human plasma and shown, by electron microscopy, to have a diameter of about 50-60 nm.
  • the HCV genome is a single-stranded, positive-sense RNA of about 9,600 bp coding for a polyprotein of 3009-3030 amino-acids, which is cleaved co and post-translationally into mature viral proteins (core, El, E2, p7, NS2, NS3, NS4A, NS4B, NS5A, NS5B). It is believed that the structural glycoproteins, El and E2, are embedded into a viral lipid envelope and form stable heterodimers. It is also believed that the structural core protein interacts with the viral RNA genome to form the nucleocapsid.
  • the nonstructural proteins designated NS2 to NS5 include proteins with enzymatic functions involved in virus replication and protein processing including a polymerase, protease and helicase.
  • HCV infection The main source of contamination with HCV is blood.
  • the magnitude of the HCV infection as a health problem is illustrated by the prevalence among high-risk groups. For example, 60% to 90% of hemophiliacs and more than 80% of intravenous drug abusers in western countries are chronically infected with HCV. For intravenous drug abusers, the prevalence varies from about 28% to 70% depending on the population studied. The proportion of new HCV infections associated with post-transfusion has been markedly reduced lately due to advances in diagnostic tools used to screen blood donors. [0004] Combination of pegylated interferon plus ribavirin is the treatment of choice for chronic HCV infection. This treatment does not provide sustained viral response (SVR) in a majority of patients infected with the most prevalent genotype (la and lb). Furthermore, significant side effects prevent compliance to the current regimen and may require dose reduction or discontinuation in some patients.
  • SVR sustained viral response

Generally, the compounds of the invention can be prepared as shown in those syntheses optionally with any desired appropriate modification.
  • RT refers to the LCMS retention time, in minutes, associated with the compound. Unless otherwise indicated, the method employed to obtain the reported retention times is as follows:
  • RT refers to the LCMS retention time, in minutes, associated with the compound.
  • NMR and Mass Spectroscopy data of certain specific compounds are summarized in Table 1.
  • the resulting reaction mixture was stirred for 14 h at ambient temperature, then cooled to 0 °C and hydrogen peroxide added dropwise (30 % w/v solution, 1.90 mL, 16.8 mmol). The solution was stirred for 2 h, then quenched slowly with saturated aqueous sodium sulfite while the temperature was maintained at 0 °C. The resulting mixture was extracted with dichloromethane (2 x 20 mL), the combined organic extracts were washed with brine (25 mL), dried over sodium sulfate, filtered, and concentrated under reduced pressure.
  • the prodrug whose PK parameters are to be determined can be formulated as a solution in 0.5%MC/0.5%Tween 80/99% water and administered orally by gavage to rats at a dose of 3 mg/kg. Rats are weighed the day before the study. Rat plasma is sampled predose and at 15, 30 min, 1, 2, 3, 4, 6, 8, 12 and 24 hrs post dose using Instech automatic blood sampling equipment. Blood is collected in tubes containing K2-EDTA and 110 uL plasma are extracted for analysis. Rats are fed ad lib and standard IACUC and SOP protocols are followed. Plasma samples and dose samples are analyzed using LC/MS/MS for both the prodrug compound and the active metabolite. PK parameters for both analytes for each subject are calculated using the measured dose of prodrug.
  • PK parameters of a prodrug of the invention was measured as described in the preceding paragraph, and are depicted in FIG. 3. As shown in FIG. 3, the -O-alaninyl group of compound 10 in vivo converted into the -OH active metabolite.
  • PK parameters of compound 11 and 1, which were measured as described in the preceding paragraph, are also depicted in FIGs. 4 and 5, respectively. As shown in FIGs. 4 and 5, compounds 11 and 1 were in vivo converted into their active metabolites.
