Title: Therapeutic nucleosides
Abstract:The use of a 1,3-oxathiolane nucleoside analogue and pharmaceutically acceptable derivatives thereof for the treatment of hepatitis B virus infections is disclosed. Pharmaceutical formulations are also provided.
Inventor(s): Liotta; Dennis C. (McDonough, GA)
Assignee: Emory University (Atlanta, GA)
Filing Date:Jan 15, 1998
Application Number:09/007,502
Claims:1. A method of treating an HBV infection in a human having an HBV infection comprising orally administering a pharmaceutical composition suitable for oral administration containing an effective HBV infection treatment amount of a cis isomer of the compound of formula (I) ##STR5##

or a pharmaceutically acceptable salt thereof to said HBV infected human.

2. The method of claim 1, in which the compound or salt is administered in a tablet or capsule.

3. A method of treating an HBV infection in a human having an HBV infection comprising injecting said HBV infected human with a sterile liquid pharmaceutical composition containing an effective HBV infection treatment amount of a cis isomer of the compound of formula (I) ##STR6##

or a pharmaceutically acceptable salt thereof.

4. A method of treating an HBV infected host which comprises administering an effective HBV treatment amount of the compound ##STR7##

or a pharmaceutically acceptable salt thereof to said HBV infected host.

5. A method of treating an HBV infection in a host which comprises administering an effective HBV treatment amount of the compound (.+-.)-cis-1-(2-hydroxymethyl)-1,3-oxathiolan-5-yl)fluorocytosine to said HBV infected host.

6. A method of limiting Hepatitis B virus production in a plurality of human cells containing said virus which comprises the step of applying to said cells containing said virus an amount of the compound cis-1-(2-hydroxymethyl)-1,3-oxathiolan-5-yl)-5-fluorocytosine sufficient to limit production of said virus.

7. A method for the prophylaxis of an HBV infection in a host which comprises administering an effective amount of the compound (.+-.)-cis-1-(2-hydroxymethyl)-1,3-oxathiolan-5-yl)fluorocytosine to said HBV infected host.

8. A method for theMtreatment of a hepatitis B infection in an infected host which comprises administering an effective HBV treatment amount of the compound cis-(2-hydroxymethyl)-1,3-oxathioan-5-yl)-5-fluorocytosine substantially in the form of one optical isomer or its pharmaceutically acceptable salt to the hepatitis B infected host.

9. A method for the treatment of a hepatitis B infection in an infected host which comprises administering an effective HBV treatment amount of a compound consisting essentially of one optical isomer of cis-(2-hydroxymethyl)-1,3-oxathioan-5-yl)-5-fluorocytosine substantially in the form of one optical isomer or its pharmaceutically acceptable salt to the hepatitis B infected host.

10. The method of claim 8, wherein the optical isomer is the (-)-optical isomer.

11. The method of claim 8, wherein the optical isomer is the (+)-optical isomer.

12. The method of claim 9, wherein the optical isomer is the (-)-optical isomer.

13. The method of claim 9, wherein the optical isomer is the (+)-optical isomer.

14. The methods of claims 9-13 wherein the host is a human.
