Abstract

The disclosed invention provides compositions and methods of treating a Flaviviridae infection, including hepatitis C virus, West Nile Virus, yellow fever virus, and a rhinovirus infection in a host, including animals, and especially humans, using a (2′R)-2′-deoxy-2′-fluoro-2′-C-methyl nucleosides, or a pharmaceutically acceptable salt or prodrug thereof.

Claims (84)

1. A method of inhibiting the proliferation of hepatitis C virus in a human subject infected with the virus comprising providing to the subject an antivirally effective amount of a compound of the structure:

or its pharmaceutically acceptable salt

wherein R 1 and R 7 are both H;

and

R 4 is NH 2 .

2. A method of inhibiting the proliferation of a hepatitis C virus in a human subject infected with the virus comprising providing to the subject an antivirally effective amount of a compound of the structure:

or its pharmaceutically acceptable salt

wherein R 1 is monophosphate; R 7 is H; and R 4 is NH 2 .

3. A method of inhibiting the proliferation of hepatitis C virus in a human subject infected with the virus comprising providing to the subject an antivirally effective amount of a compound of the structure:

or its pharmaceutically acceptable salt

wherein R 1 is diphosphate; R 7 is H; and R 4 is NH 2 .

4. A method of inhibiting the proliferation of hepatitis C virus in a human subject infected with the virus comprising providing to the subject an antivirally effective amount of a compound of the structure:

or its pharmaceutically acceptable salt

wherein R 1 is triphosphate; R 7 is H; and R 4 is NH 2 .

5. A method of inhibiting the proliferation of hepatitis C virus in a human subject infected with the virus comprising providing to the subject an antivirally effective amount of a compound of the structure:

or its pharmaceutically acceptable salt

wherein R 1 is an H-phosphonate; R 7 is H; and R 4 is NH 2 .

6. A method of inhibiting the proliferation of hepatitis C virus in a human subject infected with the virus comprising providing to the subject an antivirally effective amount of a compound of the structure:

or its pharmaceutically acceptable salt

wherein R 1 and R 7 are both H; and R 4 is OH.

7. A method of inhibiting the proliferation of hepatitis C virus in a human subject infected with the virus comprising providing to the subject an antivirally effective amount of a compound of the structure:

or its pharmaceutically acceptable salt

wherein R 1 is monophosphate; R 7 is H; and R 4 is OH.

8. A method of inhibiting the proliferation of hepatitis C virus in a human subject infected with the virus comprising providing to the subject an antivirally effective amount of a compound of the structure:

or its pharmaceutically acceptable salt

wherein R 1 is diphosphate; R 7 is H; and R 4 is OH.

9. A method of inhibiting the proliferation of hepatitis C virus in a human subject infected with the virus comprising providing to the subject an antivirally effective amount of a compound of the structure:

or its pharmaceutically acceptable salt

wherein R 1 is triphosphate; R 7 is H; and R 4 is OH.

10. A method of inhibiting the proliferation of hepatitis C virus in a human subject infected with the virus comprising providing to the subject an antivirally effective amount of a compound of the structure:

or its pharmaceutically acceptable salt

wherein R 1 is an H-phosphonate; R 7 is H; and R 4 is OH.

11. A method for the treatment of a hepatitis C infection, comprising:

providing to a human in need thereof an antivirally effective amount of a compound of the structure:

or its pharmaceutically acceptable salt

wherein R 1 and R 7 are both H; and

R 4 is NH 2 .

12. A method for the treatment of a hepatitis C infection, comprising:

providing to a human in need thereof an antivirally effective amount of a compound of the structure:

or its pharmaceutically acceptable salt

wherein

R 1 is monophosphate and R 7 is H; and

R 4 is NH 2 .

13. A method for the treatment of a hepatitis C infection, comprising:

providing to a human in need thereof an antivirally effective amount of a compound of the structure:

or its pharmaceutically acceptable salt

wherein R 1 is diphosphate and R 7 is H; and

R 4 is NH 2 .

14. A method for the treatment of a hepatitis C infection, comprising:

providing to a human in need thereof an antivirally effective amount of a compound of the structure:

or its pharmaceutically acceptable salt

wherein R 1 is triphosphate and R 7 is H; and

R 4 is NH 2 .

15. A method for the treatment of a hepatitis C infection, comprising:

providing to a human in need thereof an antivirally effective amount of a compound of the structure:

or its pharmaceutically acceptable salt

wherein R 1 is H-phosphonate and R 7 is H; and

R 4 is NH 2 .

16. A method for the treatment of a hepatitis C infection, comprising:

providing to a human in need thereof an antivirally effective amount of a compound of the structure:

or its pharmaceutically acceptable salt

wherein R 1 and R 7 are both H; and

R 4 is OH.

17. A method for the treatment of a hepatitis C infection, comprising:

providing to a human in need thereof an antivirally effective amount of a compound of the structure:

or its pharmaceutically acceptable salt

wherein R 1 is monophosphate and R 7 is H; and

R 4 is OH.

18. A method for the treatment of a hepatitis C infection, comprising:

providing to a human in need thereof an antivirally effective amount of a compound of the structure:

or its pharmaceutically acceptable salt

wherein R 1 is diphosphate and R 7 is H; and

R 4 is OH.

19. A method for the treatment of a hepatitis C infection, comprising:

providing to a human in need thereof an antivirally effective amount of a compound or its-pharmaceutically acceptable salt of the structure:

or its pharmaceutically acceptable salt

wherein R 1 is triphosphate and R 7 is H; and

R 4 is OH.

20. A method for the treatment of a hepatitis C infection, comprising:

providing to a human in need thereof an antivirally effective amount of a compound of the structure:

or its pharmaceutically acceptable salt

wherein R 1 is H-phosphonate and R 7 is H; and

R 4 is OH.

21. A method as recited in any one of the preceding claims, wherein the antivirally effective amount of the compound is administered in combination or alternation with at least one treatment selected from the group consisting of an antiviral treatment, an antibacterial treatment, an anticancer treatment, and interferon.
