A. Structural representation of clickable sugars. The structures of glucose-azide, galactose-azide and mannose-azide with PEG linkers (β-D-Glucose-PEG4-azide (1a), β-D-Galactose-PEG4-azide (1b), and α-D-Mannose-PEG4-azide (1c)) are presented; B. Synthetic protocol for dendrimer-sugar conjugates. The synthesis of fluorescently labeled Cy5-D-Glucose, Cy5-D-Mannose, and Cy5-D-Galactose is presented using CuAAC click chemistry approach.
