Compositions, methods of synthesis and use of carbohydrate targeted agents

Abstract

The invention provides D02S derivatives conjugated to monosaccharide ligands directly or through a linker and optionally chelated to a metal, wherein the D02S derivatives having the following structure: wherein R', R′ are each independently —OH or —O-alkyl; Ris a hydrogen, a linker, or a ligand; Ris a linker and/or a ligand; and n is an integer from 1 to 10; the linker is an amino acid, a peptide, an amino alcohol, a polyethylylene glycol, an alkyl, an alkenyl, an alkynyl, an azide, an aromatic compound, a carboxylic acid, or an ester, the alkyl, alkenyl, or alkynyl is optionally substituted with an alkyl, a halogen, a nitro group, a hydroxyl group, an amino group, or a carboxyl group; the ligand is a GLUT1 targeting moiety.
