Liponucleosidos Dry Nucleosides, Process for their Preparation and compositions containing them with antiviral activity.

摘要

The invention provides a general formula (I): R1 is a saturated or unsaturated, unsaturated, straight-line or branch tar chain, containing up to 20 carbon atoms, which can be replaced once or more by 1 to 6 carbon atoms of phenyl, halogen and carbon atoms. R2 is a saturated or unsaturated, unsaturated, linear or separator tar chain, which contains up to 20 carbon atoms. One or more carbon atoms can be replaced optionally. Phenyl, halogen,There are 1 to 6 carbon atoms, commercial tar, 1 to 6 carbon atoms, oxygen carbides, 1 to 6 carbon atoms of hydrogen sulfide, 1 to 6 carbon atoms or 1 to 6 carbon atoms of tar, R3 hydrogen atoms or 1 to 6 carbon atoms of radical tar, which can be replaced by hydroxyl group. R4 is an atom. In hydrogen, a hydroxyl or amino group or an Amin group is replaced once or twice by a tar of 1 to 6 carbon atoms, R5 is a hydrogen atom, a hydroxyl or ammonia group, or an Amin group is replaced once or twice by a tar of 1 to 6 carbon atoms,X is a link in Valencia, or oxygen or sulfur atom, or sulfur or sulfur group, with the same meaning as X, so x and Y may be the same or different, Z is oxygen or sulfur atom, and its ceramic strength and physiologically acceptable salt containing acid and inorganic base. The present invention also provides procedures for the preparation of these antiviral lipolysis and pharmaceutical compounds, at least one of which is lipolysis.
