Patent ID: 8921533

Claim:
A compound of formula IV or V: wherein R 1 is a naturally occurring saccharide linked at the anomeric carbon of the saccharide, provided R1 is not glucuronate; each of R 6 and R 7 is independently a linear or branched, saturated or partially unsaturated aliphatic C 2 -C 20 hydrocarbon chain; each of R 8 and R 9 is independently a linear or branched aliphatic C 2 -C 20 hydrocarbon chain which is optionally substituted with a C 3 -C 9 aliphatic or aromatic cyclohydrocarbon or heterocyclic group or having 1-3 substituents independently selected from the group consisting of halogen atoms, amino, hydroxy, carboxylic acid group, ester, amide, and cyano wherein one or more of the hydroxy, carboxylic acid, amine, or amide group is optionally glycosylated with a saccharide group; and Y is a bond or —CH 2 -aryl-O—, wherein the aryl group is optionally substituted with one or more substituents independently selected from C 1 -C 6 alkyl, C 1 -C 6 haloalkyl, C 1 -C 6 alkoxy, C 1 -C 6 haloalkoxy, C 1 -C 6 thioalkyl, —N(C 1 -C 3 alkyl)(C 1 -C 3 alkyl), —NH(C 1 -C 3 alkyl), —NH 2 , —NO 2 , and —CN; or a pharmaceutically acceptable salt thereof, wherein the compound is predominantly an individual anomer.
