5. A pharmaceutical composition comprising an effective amount of the compound of claim 1 , or a pharmaceutically acceptable salt thereof, and a pharmaceutically acceptable carrier.
6. The pharmaceutical composition of claim 5 , further comprising one or more additional therapeutic agents, wherein the additional therapeutic agents are each independently selected from HCV protease inhibitors, HCV NS5A inhibitors and HCV NS5B polymerase inhibitors.
7. A pharmaceutical composition consisting essentially of the compound of claim 1 , or a pharmaceutically acceptable salt thereof, a HCV protease inhibitor, a HCV NS5B polymerase inhibitor and a pharmaceutically acceptable carrier, wherein the amounts of the compound of claim 1 , or a pharmaceutically acceptable salt thereof, the HCV protease inhibitor and the HCV NS5B polymerase inhibitor are together effective to treat HCV infection in a human patient.
8. The pharmaceutical composition of claim 7 , wherein the HCV protease inhibitor is the compound having the structure:
9. The pharmaceutical composition of claim 8 , wherein the HCV NS5B polymerase inhibitor is a nucleoside.
10. A method of treating a human patient infected with HCV, comprising the step of administering an amount of the compound of claim 1 , or a pharmaceutically acceptable salt thereof, effective to treat infection by HCV in said human patient.
11. The method of claim 10 , further comprising administering one or more additional therapeutic agents to said human patient, wherein the additional therapeutic agents are each independently selected from HCV protease inhibitors, HCV NS5A inhibitors and HCV NS5B polymerase inhibitors.
12. The method of claim 11 , wherein the one or more additional therapeutic agents comprise a HCV protease inhibitor and a HCV NS5B polymerase inhibitor.
13. The method of claim 12 , wherein the HCV protease inhibitor is the compound having the structure:
14. The method of claim 13 , wherein the HCV NS5B polymerase inhibitor is a nucleoside.
15. A pharmaceutical composition comprising an effective amount of the compound of claim 3 and a pharmaceutically acceptable carrier.
16. The pharmaceutical composition of claim 15 , further comprising one or more additional therapeutic agents, wherein the additional therapeutic agents are each independently selected from HCV protease inhibitors, HCV NS5A inhibitors and HCV NS5B polymerase inhibitors.
17. A pharmaceutical composition consisting essentially of the compound of claim 3 , a HCV protease inhibitor, a HCV NS5B polymerase inhibitor and a pharmaceutically acceptable carrier, wherein the amounts of the compound of claim 3 , the HCV protease inhibitor and the HCV NS5B polymerase inhibitor are together effective to treat HCV infection in a human patient.
18. The pharmaceutical composition of claim 17 , wherein the HCV protease inhibitor is the compound having the structure:
19. The pharmaceutical composition of claim 18 , wherein the HCV NS5B polymerase inhibitor is a nucleoside.
20. A method of treating a human patient infected with HCV, comprising the step of administering an amount of the compound of claim 3 effective to treat infection by HCV in said human patient.
21. The method of claim 20 , further comprising administering one or more additional therapeutic agents to said human patient, wherein the additional therapeutic agents are each independently selected from HCV protease inhibitors, HCV NS5A inhibitors and HCV NS5B polymerase inhibitors.
22. The method of claim 21 , wherein the one or more additional therapeutic agents comprise a HCV protease inhibitor and a HCV NS5B polymerase inhibitor.
23. The method of claim 22 , wherein the HCV protease inhibitor is the compound having the structure:
24. The method of claim 23 , wherein the HCV NS5B polymerase inhibitor is a nucleoside.
