Abstract

A method and composition for the treatment of HIV and HBV infections in humans and other host animals is disclosed that includes the administration of an effective amount of a 5-carboxamido or 5-fluoro!-2'"'"',3'"'"'-dideoxy-2'"'"',3'"'"'-didehydro-pyrimidine nucleoside or a 5-carboxamido or 5-fluoro!-3'"'"'-modified-pyrimidine nucleoside, or a mixture or a pharmaceutically acceptable derivative thereof, including a 5'"'"' or N⁴ alkylated or acylated derivative, or a pharmaceutically acceptable salt thereof, in a pharmaceutically acceptable carrier.

Claims

1. A composition comprising an effective HIV or HBV treatment amount of a compound of the formula:

##STR3## wherein R is hydrogen, monophosphate, diphosphate, or triphosphate;

in combination or alternation with a second compound selected from the group consisting of 2-hydroxymethyl-5-(5-fluorocytosin-1-yl)-1,3-oxathiolane, 2-hydroxymethyl-5-(cytosin-1-yl)-1,3-oxathiolane;

9- 4-(hydroxymethyl)-2-cyclopenten-1-yl!-guanine (carbovir), 9- (2-hydroxyethoxy)methyl!guanine (acyclovir) interferon, 3'"'"'-deoxy-3'"'"'-azidothymidine (AZT), 2'"'"',3'"'"'-dideoxyinosine (DDI), 2'"'"',3'"'"'-dideoxycytidine (DDC), (-)-2'"'"'-fluoro-5-methyl-β

-L-ARAuridine (L-(-)-FMAU) and 2'"'"',3'"'"'-didehydro-2'"'"',3'"'"'-dideoxythymidine (D4T).

2. The composition of claim 1, wherein R is hydrogen.

3. The composition of claim 1, wherein R is monophosphate.

4. The composition of claim 1, wherein R is selected from the group consisting of diphosphate and triphosphate.

5. The composition of claim 1, wherein R is diphosphate.

6. The composition of claim 1, wherein the second compound is 2-hydroxymethyl-5-(5-fluorocytosin-1-yl)-1,3-oxathiolane.

7. The composition of claim 1, wherein the second compound is 2-hydroxymethyl-5-(cytosin-1-yl)-1,3-oxathiolane.

8. The composition of claim 1, wherein the second compound is carbovir.

9. The composition of claim 1, wherein the second compound is acyclovir.

10. The composition of claim 1, wherein the second compound is interferon.

11. The composition of claim 1, wherein the second compound is AZT.

12. The composition of claim 1, wherein the second compound is DDI.

13. The composition of claim 1, wherein the second compound is DDC.

14. The composition of claim 1, wherein the second compound is L-(-)-FMAU.

15. The composition of claim 1, wherein the second compound is D4T.

16. The composition of claim 1, wherein the combination is effective against HIV.

17. The composition of claim 1, wherein the alternation is effective against HIV.

18. The composition of claim 1, wherein the combination is effective against HBV.

19. The composition of claim 1, wherein the alternation is effective against HBV.
