Despite the growing importance of synthetic glycans as tools for biological studies and drug discovery, a lack of common methods for the routine synthesis remains a major obstacle. We have developed a new method for automated glycan synthesis that employs the enzymatic approach and a dendrimer as an ideal support within the chemical process. Recovery tests using a hollow fiber ultrafiltration module have revealed that monodisperse G6 (MW = 58 kDa) and G7 (MW = 116 kDa) poly(amidoamine) dendrimers exhibit a similar profile to BSA (MW = 66 kDa). Characteristics of the globular protein-like G7 dendrimer with high solubility and low viscosity in water greatly enhanced throughput and efficiency in automated synthesis while random polyacrylamide-based supports entail significant loss during the repetitive reaction/separation step. The present protocol allowed for the fully automated enzymatic synthesis of sialyl Lewis X tetrasaccharide derivatives over a period of 4 days in 16% overall yield from a simple N-acetyl-d-glucosamine linked to an aminooxy-functionalized G7 dendrimer.
