    摘要: A method for using thiazine dyes, especially methylene blue, alone or in combination with low levels of light, to selectively inactivate or inhibit intracellular replication of specific viruses, especially human immunodeficiency virus in vitro and in vivo. Examples of useful thiazine dyes are methylene blue, azure A, azure C, toluidine blue O, and thionine. The preferred dye at this time is methylene blue. Methylene blue is FDA approved for topical, i.v., and oral administration, and has minimal side effects. Since methylene blue absorbs in the red wavelengths, i.e., approximately 670 nm, which penetrates tissue much better than other lower wavelengths, light penetrating the skin to the capillaries at the surface can be used to enhance the activity of the dye.

    摘要: The present invention provides an isolated HIV-1 mutant and isolated nucleic acid molecules comprising HIV-RT coding sequences harboring a novel mutation in the S68 codon, and in particular, deletions of the S68 codon. This novel deletion reduces the sensitivity of HIV to various nucleoside reverse transcriptase inhibitors. Methods of using this mutation for selecting effective antiretroviral agents in vitro and in vivo, methods for monitoring infection progression in HIV-infected individuals and methods for avoiding the emergence of and/or to treat individuals infected with HIV comprising mutations, including deletions, at the S68 codon of HIV-RT are provided.

    摘要: The present invention is directed to compounds, compositions and methods for treating or preventing viral infections using nucleoside analog monophosphate prodrugs. More specifically, HCV, Norovirus, Saporovirus, Dengue virus, Chikungunya virus and Yellow fever in human patients or other animal hosts. The compounds are certain 2,6-diamino 2-C-methyl purine nucleoside monophosphate prodrugs and modified prodrug analogs, and pharmaceutically acceptable, salts, prodrugs, and other derivatives thereof. In particular, the compounds show potent antiviral activity against HCV, Norovirus, Saporovirus, Dengue virus, Chikungunya virus and Yellow fever. This invention teaches how to modify the metabolic pathway of 2,6-diamino 2′-C-methyl purine and deliver nucleotide triphosphate(s) to polymerases at heretofore unobtainable therapeutically-relevant concentrations.
