A 1,2-dideoxy-1,2-diamino oligosaccharide or polysaccharide in its free base, salt or metal-complex form as shown in General Formula 1 and derivative thereof is described. R1, R2 and R3 are each independently selected from the group consisting of H and a carbohydrate moiety, with the proviso that at least one of the groups R1, R2 or R3 is a carbohydrate moiety; R4 is selected from the group consisting of: H, optionally substituted C1-20-alkyl, optionally substituted heteroalkyl, optionally substituted C2-20-alkenyl, optionally substituted C2-20-alkynyl, optionally substituted C3-10-cycloalkyl, optionally substituted heterocyclyl, optionally substituted aryl, and optionally substituted heteroaryl. |
