Methods and compositions for inhibition of polymerase
View Patent ↗The present invention is directed to methods and compositions for inhibition of viral nucleic acid polymerases, such as RNA and DNA polymerases, and methods and compositions that are useful for treating viral infections in subjects. The methods comprise administering to the subject a therapeutically effective amount of a compound of formula I, or a pharmaceutically acceptable salt or hydrate thereof, or a composition comprising a compound of formula I, or a pharmaceutically acceptable salt or hydrate thereof, and a pharmaceutically acceptable carrier. The composition or method may optionally comprise one or more additional anti-viral agents.
1. A method for treating a viral infection, comprising administering to a human subject in need thereof a therapeutically effective amount of a compound having the following structure:
or a pharmaceutically acceptable salt or hydrate thereof; wherein the virus is selected from the group consisting of viruses of the orthomyxoviridae, bunyaviridae, flaviviridae, and filoviridae families.
2. The method of claim 1 , wherein the virus is selected from the group consisting of Ebola, West Nile, yellow fever, Dengue fever, influenza A, influenza B, Rift Valley Fever, and Marburg viruses.
3. The method of claim 2 , wherein the virus is West Nile, yellow fever, Dengue fever, influenza A, influenza B, or Rift Valley Fever virus.
4. The method of claim 2 , wherein the virus is Ebola, Marburg, or yellow fever virus.
5. The method of claim 4 , wherein the virus is Marburg or yellow fever virus.
6. The method of claim 2 , further comprising co-administering to the human subject an effective amount of an anti-viral agent.
7. The method of claim 6 , wherein the anti-viral agent is a neuraminidase inhibitor.
8. The method of claim 6 , wherein the anti-viral agent is selected from the group consisting of laninamivir, oseltamivir, zanamivir, and peramivir.
9. The method of claim 6 , wherein the anti-viral agent is peramivir.
10. The method of claim 2 , wherein the compound is administered intravenously, intraperitoneally, intramuscularly, or orally.
11. A method for suppressing a viral infection, comprising administering to a human subject in need thereof a therapeutically effective amount of a compound having the following structure:
or a pharmaceutically acceptable salt or hydrate thereof; wherein the virus is selected from the group consisting of viruses of the orthomyxoviridae, bunyaviridae, flaviviridae, and filoviridae families.
12. The method of claim 11 , wherein the virus is selected from the group consisting of Ebola, West Nile, yellow fever, Dengue fever, influenza A, influenza B, Rift Valley Fever, and Marburg viruses.
13. The method of claim 12 , wherein the virus is West Nile, yellow fever, Dengue fever, influenza A, influenza B, or Rift Valley Fever virus.
14. The method of claim 12 , wherein the virus is Ebola, Marburg, or yellow fever virus.
15. The method of claim 14 , wherein the virus is Marburg or yellow fever virus.
16. The method of claim 12 , further comprising co-administering to the human subject an effective amount of an anti-viral agent.
17. The method of claim 16 , wherein the anti-viral agent is a neuraminidase inhibitor.
18. The method of claim 16 , wherein the anti-viral agent is selected from the group consisting of laninamivir, oseltamivir, zanamivir, and peramivir.
19. The method of claim 16 , wherein the anti-viral agent is peramivir.
20. The method of claim 12 , wherein the compound is administered intravenously, intraperitoneally, intramuscularly, or orally.
