The invention relates to a polyglycerol derivative, comprising a dendritic polyglycerol backbone and at least one substituent in the nature of a covalently bound negatively charged group chosen from the group consisting of sulfates, sulfonates, phosphates, phosphonates, bisphosphonates, carboxylates and combinations thereof. The polyglycerol derivative is characterized in that the substituent is bound to the polyglycerol backbone via a linker, the linker being chosen from the group consisting of moieties being or comprising a carbamate group, an ester group, an orthoester group, an amide group, a disulfide bridge group, an acetal group, an imine group and combinations thereof. The invention also relates to uses of such a polyglycerol derivative and to a method of manufacturing the same. |
