Abstract

The invention provides a novel therapeutic composition comprising a pharmaceutically acceptable carrier containing a therapeutically effective amount of an ethereal monosubstitution of a monosaccharide derivative having the general formula S--O--Y, wherein S is the residue of the monosaccharide derivative selected from the group consisting of pentoses, hexoses and heptoses as single or polysubstituted acetals, ketals or esters and Y is selected from the group consisting of cyclic monovalent nitrogen-containing organic radicals and residua and monovalent organic radicals and residua having the general formula ##STR1## wherein R.sub.1 is a divalent organic radical having a linear carbon chain length of about 1-7 carbon atoms and R.sub.2 and R.sub.3 are selected from the group consisting of --H, --OH, --SH, halogen and monovalent organic radicals and residua having a linear carbon chain length of about 1-7 carbon atoms. The invention also provides certain novel ethereal monosubstitutions of monosaccharide derivatives, of which 3-O-3'-(N',N'-dimethylamino-n-propyl)-1,2-O-isopropylidene-D-glucofuranose is an example. The novel monosaccharide derivatives show striking antiviral activity or other therapeutically valuable properties and are useful as active ingredients in the above therapeutic composition. The invention further provides a method of therapeutically treating warm-blooded animals with the aforementioned therapeutic composition and novel monosubstituted monosaccharide derivatives.
