| 摘要 |
Nucleotide linked 2-deoxy-2-fluoroglycosides are employed as potent competitive inhibitors of glycosyltransferases. More particularly, uridine-5'-diphospho-2-deoxy-2-fluoro-galactose (UDP-2F-Gal), guanidine-5'-diphospho-2-deoxy-2-fluoro-L-fucose (GDP-2F-Fuc), uridine-5'-diphospho-2-deoxy-2-fluoro-D-glucose (UDP-2F-Glu), guanosine-5'-diphospho-2-deoxy-2-fluoro-D-mannose (GDP-2F-Man), cytosine-5'-monophospho-2-deoxy-2-fluoro-D-sialic acid, and cytosine-5'-monophospho-2-deoxy-2-KDO may be employed as inhibitors of beta -1,4-galactosyltransferase, alpha -1,3-fucosyltransferase, glucosyltransferases, N-acetylglucosaminyltransferases, alpha -mannosyltransferases, alpha -sialyltransferases, and KDO-transferases, respectively. Synthesis of nucleotide-linked-2-deoxy-2-fluoroglycosides is achieved using either chemoenzymatic or chemical methodologies.
