摘要:
The present invention relates to pyrimidine nucleoside compounds and their use to treat viral infections of Varicella Zoster virus and Epstein Barr Virus, as well as cancers which are complications of Epstein Barr virus.
摘要:
The present invention relates to the discovery that certain .beta.-L-dioxolane nucleoside analogs which contain a uracil base, and preferably, a 5-halosubstituted uracil base, exhibit unexpectedly high activity against Epstein-Barr virus (EBV), Varciella-Zoster virus (VZV) and Herpes Virus 8 (HV-8). In particular, the compounds according to the present invention show potent inhibition of the replication of the virus (viral growth) in combination with very low toxicity to the host cells (i.e., animal or human tissue). Compounds are useful for treating EBV, VZV and HV-8 infections in humans.
摘要:
A method for stabilizing an oligonucleotide by including a .beta.-L-2'-deoxy-2'-fluoro-arabinofuranosyl nucleoside at the 5'-terminus, the 3'-terminus, or in the interior of the oligonucleotide. The oligonucleotide can be used in the modulation of gene expression through a process wherein a synthetic oligonucleotide is hybridized to a complementary nucleic acid sequence to inhibit transcription or replication of DNA or to inhibit translation or processing of RNA.

摘要:
A compound, and a pharmaceutical composition comprising an effective mount to treat HBV or EBV of a compound, of the formula: ##STR1## wherein R is selected from the group consisting of 5-methyluracil, adenine and cytosine, and R' is hydrogen, acyl, or alkyl or a monophosphate, diphosphate or triphosphate ester, or its pharmaceutically acceptable salt.
摘要:
A method for the treatment of a human infected with EBV that includes administering an EBV-treatment amount of an L-nucleoside of the formula: ##STR1## wherein R is 5-methyluracil, and R' is hydrogen, acyl, alkyl or a monophosphate, diphosphate or triphosphate ester, or its pharmaceutically acceptable salt.
摘要:
The present invention relates to the use of prodrug forms of (−)-(2S,4S)-1-(2-hydroxymethyl-1,3-dioxolan-4-yl)cytosine to treat psoriasis, genital warts and other hyperproliferative keratinocyte diseases such as hyperkeratosis, ichthyosis, keratoderma or lichen planus.

摘要:
Oligonucleotides that include a 2'-fluoro .beta.-L-arabinofuranosyl nucleoside at the 3'-terminus, the 5'-terminus or in the interior of the oligomer. A preferred nucleoside is 2'-fluoro-5-methyl-.beta.-L-arabinofuranosyluridine (also referred to as L-FMAU). This compound is a potent antiviral agent against HBV and EBV and exhibits low cytotoxicity. Other specific examples of active compounds include N.sub.1 -(2'-deoxy-2'-fluoro-.beta.-L-arabinofuranosyl)-5-ethyluracil, N.sub.1 -(2'-deoxy-2'-fluoro-.beta.-L-arabinofuranosyl)-5-iodocytosine), and N.sub.1 -(2'-deoxy-2'-fluoro-.beta.-L-arabinofuranosyl)-5-iodouracil.
