  Synthetic Potential of Fucosyltransferase III for the Synthesis of Fluorescent‐labeled Milk Oligosaccharides

  摘要：

  Various fundamental biologic roles of milk oligosaccharides have been recognized; however, their structure-affinity relationship is still not fully revealed. Herein, we describe the synthesis of the fluorescent-labeled milk oligosaccharides 3-(5-dimethylaminonaphthalene-1-sulfonylamino)propyl beta-D-galactopyranosyl-(1 -> 3)-[alpha-L-fucopyranosyl-(1 -> 4)]-2-acetamido-2-deoxy-beta-D-glucopyranoside (1) and 3-(5-dimethylamino-naphthalene-1-sulfonylamino)propyl beta-D-galactopyranosyl-(1 -> 3)-[alpha-L-fucopyranosyl-(1 -> 4)]-beta-D-glucopyranoside (2) as useful tools for synthetic, analytic, and biologic applications. For the fucosylation of lactose and lacto- N -biose, the chemical and the enzymatic syntheses using fucosyltransferase III were compared.
