실험 절차

As depicted in above Scheme 4, 6-arm PEG (1) synthesized in the Scheme 1 is reacted with succinic reagents, e.g., succinic anhydride and toluene as solvent to synthesize 6-arm PEG-succinic acid (6-arm PEG-SA) (6). The 6-arm PEG SA (6) is reacted with N-hydroxy succinimide (NHS) and N, N′-dicyclohexylcarbodiimide (DCC) to produce 6-arm PEG-succinimide succinate (6-arm PEG-SS) (7).
