摘要:
A method and composition for the treatment of humans infected with HBV that includes the administration of an HBV treatment amount of a .beta.-dioxolanyl purine nucleoside of the formula: ##STR1## wherein R is OH, Cl, NH.sub.2, or H, or a pharmaceutically acceptable salt or derivative of the compound, optionally in a pharmaceutically acceptable carrier or diluent.
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 relates to a method of preparing the antiviral compounds 2'-deoxy-5-fluoro-3'thiacytidine (FTC) and various prodrug analogues of FTC from inexpensive precursors with the option of introducing functionality as needed; methods of using these compounds, particularly in the prevention and treatment of AIDS; and the compounds themselves. This synthetic route allows the stereoselective preparation of the biologically active isomer of these compounds and related compounds.
摘要:
A compound which exhibits antiviral activity towards HTLV-III/LAV, having the formula: ##STR1## wherein R.sup.4 is O or NH; R.sup.5 is a C.sub.2-4 alkyl group or a C.sub.3-4 cycloalkyl group, wherein said alkyl group or cycloalkyl group may be substituted by one or more of Cl, Br, I, F, OH, N.sub.3, NH.sub.2, SO.sub.3 H, or COOH; R.sup.6 is hydrogen or a C.sub.1 -C.sub.4 alkyl group, which may be substituted by Cl, Br, I, F, OH, N.sub.3, NH.sub.2, SO.sub.3 H, or COOH; R.sup.3' is N.sub.3, NH.sub.2, or H; and R.sup.5' is N.sub.3, NH.sub.2, OH, phosphate, or a C.sub.1-4 acyl group.
摘要:
The present invention is directed to compounds, compositions and methods for treating or preventing HIV and other viral infections, particularly where the virus is present in macrophages, microglia, and primary myeloid cells, and eliminating and/or treating infection in patients infected by these viruses.
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.
摘要:
A method and composition for treating a host infected with a Caliciviridae virus, such as a Norovirus, comprising administering an effective treatment amount of a described modified nucleoside or a pharmaceutically acceptable salt thereof, is provided.
摘要:
The present invention is directed to compounds, compositions and methods for treating or preventing cancer and viral infections, in particular, HIV and HBV, in human patients or other animal hosts. The compounds are certain 6-substituted-2-amino-purine dioxolane monophosphates or phosphonates, and pharmaceutically acceptable, salts, prodrugs, and other derivatives thereof.
