Crude Proteinase N was used as catalyst for the synthesis of carbohydrate (in particular sucrose) esters by transesterification of activated esters in organic solvents. Polymerisable or amphiphilic sucrose esters (methacrylates and laurates) were obtained regioselectively in good yields. The influence of the reaction parameters (temperature, pH, solvent, chain length, solid support) on the reaction rate, yield and selectivity was studied. (C) 2001 Elsevier Science Ltd.

Trehalose-based nanogels for stabilizing and controlled releasing biomolecules such as glucagons are disclosed. Specifically, trehalose-based nanogels comprise (a) a copolymer comprising first methacrylate units and second methacrylate units, wherein (i) the first methacrylate units comprise trehalose side chains; and (ii) the second methacrylate units comprise disulfide side chains; (b) dithiol cross-linkers; wherein the dithiol cross-linkers cross link the copolymer through the disulfide side chains of the second methacrylate units.
