  • Publication number: 20030100766
    Abstract: The present invention relates to 3-substituted and 2,3-disubstituted pyridine compounds which are useful as intermediates in the synthesis of pyridylsulfonylurea herbicides. The invention also relates to arylation of alcohols using a pyridinediazonium salt. More particularly the arylation process of the instant invention relates to the synthesis of 2,3-disubstituted pyridine compounds via anhydrous diazotization of 3-amninopyridines to form a diazonium salt intermediate that is then reacted with the appropriate alcohol to produce the desired product. The invention additionally relates to pyridine-3-diazonium salt intermediates.

  • Patent number: 6531581
    Abstract: Compounds are described comprising purines substituted at the C-8 position and pyrimidines substituted at the C-4 position with a linker and quencher. These compounds, when incorporated into hairpin oligonucleotides quench the fluorescence of fluorophores linked to the 5′-terminus of the oligonucleotide. These nucleotide-quencher compounds are also easily incorporated into oligonucleotides using conventional or automated oligonucleotide synthetic techniques.

  • Patent number: 6140368
    Abstract: The present invention relates to a novel class of compounds that are potent inhibitors of HIV reverse transcriptase and HIV integrase. In addition to being multienzyme inhibitors, the inventive compounds of the present invention are remarkable in at least two other respects. First, they do not appear to be toxic to cells at typical therapeutic concentrations. Second, they appear to be equally effective against mutant strains of HIV reverse transcriptase commonly found in patients who have developed resistance to current reverse transcriptase inhibitors. Because the inventive compounds show promise in combatting viral resistance and are potent inhibitors of both HIV reverse transcriptase and integrase, they are ideal candidates for use in combination with existing therapies or alone in treating AIDS or HIV infection.
