摘要:
This invention relates to a purine or pyrimidine phosphonate compound of formula (I) or pharmaceutically acceptable salt thereof; wherein B, X, and R1-R3 are as defined in classes and subclasses herein. These compounds may be used as antiviral precursors. The invention also relates to therapeutic compositions of these compounds and their use for the preparation of a medication for testing and/or preventing a viral infection in a patient. The invention also provides methods for making these compounds. In particular, the invention provides an H-phosphinate precursor intermediate of formula (II) wherein B is a purine or pyrimidine base as defined herein and R1 is selected from the group comprising a hydrogen atom, and a methyl, ethyl, hydroxymethyl, hydroxyethyl and C1-6haloalkyl group.

摘要:
We describe the use of bicyclic carbohydrates for the treatment of hepatitis C virus infections. Different bicyclic carbohydrates were tested in vitro against DNA-viruses, retro-viruses and Flaviviridae sp., an important family of human and animal RNA pathogens. Significant activity was observed against the bovine viral diarrhea virus (BVDV). As pestiviruses, such as BVDV, share many similarities with hepatitis C virus (HCV), the bicyclic carbohydrates in general and the preferred bicyclic carbohydrates more specifically are expected to be a treatment for hepatitis C viral infections.

The present invention relates to the use of N-phosphonylmethoxyethyl nucleoside analogs for manufacturing a medicament for the treatment or prevention of Koi Herpes virus infections in fish, especially in carps.
摘要:
Disclosed are 1,3-Dioxoindene derivatives, pharmaceutically acceptable salts thereof or enantiomers, a preparation method thereof, and a pharmaceutical composition for the prevention or treatment of viral diseases, comprising the same as an active ingredient. The 1,3-Dioxoindene derivatives have excellent inhibitory activity against picornaviruses including coxsackie-, entero-, echo-, Polio-, and rhinoviruses, as well as exhibiting low cytotoxicity, so that they can be useful as an active ingredient of a pharmaceutical composition for the prevention or treatment of viral diseases including poliomyelitis, paralysis, acute hemorrhagic conjunctivitis, viral meningitis, hand-foot-and-mouth disease, vesicular disease, hepatitis A, myositis, myocarditis, pancreatitis, diabetes, epidemic myalgia, encephalitis, flu, herpangina, foot-and-mouth disease, asthma, chronic obstructive pulmonary disease, pneumonia, sinusitis or otitis media.
摘要:
Compounds having the general formula (I): are provided which have enhanced inhibitory potency and are thus useful in methods of prophylaxis or treatment of a viral infection such as hepatitis C virus. The compounds are phosphoramidate derivatives of nucleoside compounds derived from bases such as adenine and guanine. The glycoside moiety of the nucleoside compound can be substituted at the ss-2′ position with methyl and the phosphoramidate group can be 1-naphthyl linked by —O— to the P atom. These compounds can be administered as pharmaceutical compositions, and methods for their preparation are also provided.
摘要:
The present invention relates to the treatment, alleviation, prevention or reduction in the incidence of symptoms, diseases or conditions resulting from or associated with enteroviruses, more particularly the enteroviral infections they cause.
摘要:
The present invention relates to pharmaceutical compositions for the treatment or prevention of viral infections comprising as an active principle at least one compound having the general formula (A): wherein U is N or C; X is selected from C1-C10 alkylene, C2-10 alkenylene or C2-10 alkynylene, where each may include one or more intrachain heteroatoms selected from O, S, or NR11, provided any such heteroatom is not adjacent to the N in the ring; R3 is selected from aryl, aryloxy, arylthio, cycloalkyl, cycloalkenyl, cycloalkynyl, aryl-N(R10)—, or heterocycle, where each said substituent is optionally substituted with at least one R17, provided that for cycloalkenyl the double bond is not adjacent to a nitrogen; and the other substituents are described in the specification. The invention also relates to processes for the preparation of compounds according to the invention having above mentioned general formula, their pharmaceutically acceptable formulations and their use as a medicine or to treat or prevent viral infections.
摘要:
The present invention provides nucleotides, peptides, HCV mutants, and cell lines containing mutations associated with drug resistance. In addition, the present invention provides methods for screening for therapeutic compounds capable of inhibiting HCV as well as methods for inhibiting HCV, e.g., by targeting specific binding sites associated with HCV drug resistance.
