Abstract

A method and composition for treating a host infected with flavivirus or pestivirus comprising administering an effective flavivirus or pestivirus treatment amount of a described 1′, 2′ or 3′-modified nucleoside or a pharmaceutically acceptable salt or prodrug thereof, is provided.

Claims

1. A method for the treatment of a flavivirus or pestivirus infection in a host, comprising contacting a cell infected with a flavivirus or a pestivirus with an anti-virally effective amount of a compound of Formula X, XI or XII:

8. The method of claim 1, wherein the compound is combined with a pharmaceutically acceptable carrier.

9. The method of claim 8, wherein the carrier is suitable for oral delivery.

10. The method of claim 9, wherein the carrier is suitable for intravenous, parenteral, intradermal, subcutaneous or topical delivery.

2. A method for the treatment of a flavivirus or pestivirus infection in a host, comprising contacting a cell infected with a flavivirus or a pestivirus with an anti-virally effective amount of a compound of Formula XVII:

3. The method of claim 2, wherein the compound is

4. The method of claim 2, wherein the compound is

5. The method of claim 2, wherein the compound is in the form of a dosage unit.

6. The method of claim 5, wherein the dosage unit contains 10 to 1500 mg of said compound.

7. The method of claim 5 or 6, wherein said dosage unit is a tablet or capsule.
