摘要： A new class of diketo acids constructed on pyridinone scaffolds, designed as inhibitors of HIV replication through inhibition of HIV integrase, is described. These compounds are useful in the prevention or treatment of infection by HIV and in the treatment of AIDS and ARC, either as the compounds, or as pharmaceutically acceptable salts, with pharmaceutically acceptable carriers, used alone or in combination with antivirals, immunomodulators, antibiotics, vaccines, and other therapeutic agents, especially other anti-HIV compounds (including other integrase-based anti-HIV agents). Methods of treating AIDS and ARC and methods of treating or preventing infection by HIV are also described.

摘要： Methods and compositions, including cell cultures, for producing nucleosides are provided which comprise contacting a nucleoside precursor and a sugar moiety donor with a cell containing a nucleoside phosphorylase. The nucleoside precursor can be a purine or pyrimidine base and the sugar moiety donor can comprise a ribose, a deoxyribose, including 2-deoxyribose, or other sugar of choice. The methods and composition can be used to make thymidine from thymine and 2-deoxyinosine or 2′-deoxyadenosine. Other nucleosides, including those having anticancer and/or antiviral properties, also can be obtained according to the invention.

摘要： A new class of diketo acids constructed on pyridinone scaffolds, designed as inhibitors of HTV replication through inhibition of HIV integrase, is described. These compounds are useful in the prevention or treatment of infection by HIV and in the treatment of AIDS and ARC, either as the compounds, or as pharmaceutically acceptable salts, with pharmaceutically acceptable carriers, used alone or in combination with antivirals, immunomodulators, antibiotics, vaccines, and other therapeutic agents, especially other anti-HIV compounds (including other anti-HIV integrase agents), which can be used to create combination anti-HIV cocktails. Methods of treating AIDS and ARC and methods of treating or preventing infection by HIV are also described. Compounds of the present application include those of formula I and include tautomers, regioisomers, geometric isomers, and pharmaceutically acceptable salts thereof, wherein the pyridinone scaffold and R groups are as otherwise defined in the specification. These are combined, with any number of typical other anti-HIV agents (including other integrase-based anti-HIV agents) and other combination therapeutic agents described herein, to provide an effective treatment modality for HIV infections, including AIDS and ARC.
