摘要:
This invention is directed to a method for treating a host infected with hepatitis B comprising administering an effective amount of an anti-HBV biologically active 2′-deoxy-β-L-erythro-pentofuranonucleoside or a pharmaceutically acceptable salt or prodrug thereof, wherein the 2′-deoxy-β-L-erythro-pentofuranonucleoside has the formula: wherein R is selected from the group consisting of H, straight chained, branched or cyclic alkyl, CO-alkyl, CO-aryl, CO-alkoxyalkyl, CO-aryloxyalkyl, CO-substituted aryl, alkylsulfonyl, arylsulfonyl, aralkylsulfonyl, amino acid residue, mono, di, or triphosphate, or a phosphate derivative; and BASE is a purine or pyrimidine base which may be optionally substituted. The 2′-deoxy-β-L-erythro-pentofuranonucleoside or a pharmaceutically acceptable salt or prodrug thereof may be administered either alone or in combination with another 2′-deoxy-β-L-erythro-pentofuranonucleoside or in combination with another anti-hepatitis B agent.

摘要:
A compound, method and composition for treating a host infected with a hepatitis C viral comprising administering an effective hepatitis C treatment amount of a described 4′-disubstituted nucleoside or a pharmaceutically acceptable salt or prodrug thereof, is provided.
摘要:
The invention concerns compounds of general formula (I) (wherein R and R′ represent an alkyl radical or an aryl group and R″ is hydrogen or a CO—R1 group wherein R1 is an alkyl radical or an aryl group; and the dimers formed by the disulphide bond from one and/or the other of the two sulphur atoms of the compounds of general formula (I); and the corresponding thiazolidin forms), the methods for preparing them and uses thereof. More particularly, it concerns the use of said compounds as antioxidant agents, in particular for preparing medicines designed to increase the intracellular and/or extracellular level of glutathione (GSH).
