  Synergistic Inhibition of Human α-1,3-Fucosyltransferase V

  摘要：

  Human alpha-1,3-fucosyltransferase V (FucT V), which catalyzes the transfer of L-fucose moiety from guanosine diphosphate beta-L-fucose (GDP-Fuc) to an acceptor sugar To form sialyl Lewis x (sLe(x)), was shown to proceed through an ordered, sequential mechanism by product inhibition studies. The designed azatrisaccharide propyl 2-acetamido-2-deoxy-4-O-(beta-D-galactopyranosyl)-3 -O-(2-(N-(beta-L-homofuconojirimycinyl))ethyl)-alpha-D- glucopyranoside (2), prepared by covalently linking the N-group of beta-L-homofuconojirimycin (1) to the 3-OH of LacNAc through an ethylene unit, in the presence of GDP was found to be an effective inhibitor of FucT V. In the presence of 30 mu M GDP, the concentration of 2 necessary to cause 50% inhibition was reduced 77-fold to 31 mu M. Presumably, the azatrisaccharide and GDP form a complex which mimics the transition state of the enzymatic reaction. Given the low affinity of FucT V for its substrate LacNAc (K-m = 35 mM), the designed azatrisaccharide in the presence of GDP represents the most potent synergistic inhibitor complex reported so far.

  日期：2006.8.1

  We report an efficient route to obtain azasugars from the enantiomerically pure l- and d-diethyltartrate. The key step is a proline-catalyzed aldol condensation, in which both enantiomers of proline have been used as catalyst, affording complementary anti-aldol products.
