Simultaneous detection of different glycosidase activities by 19F NMR spectroscopy
摘要:
A fast method for the simultaneous detection of different glycosidolytic activities in commercially available enzyme preparations and crude culture filtrates was found in using, as substrate, a mixture of different glycosyl fluorides and F-19 NMR spectroscopy as a screening technique. Accompanying studies regarding the hydrolytic stability of these fluorides in various buffer systems, as well as conditions of their long-term storage, were carried out. A simple procedure for the preparation of beta-D-mannopyranosyl fluoride in gram quantities is given. (C) 2000 Elsevier Science Ltd. All rights reserved.

GRAPHICAL ABSTRACT ABSTRACT A highly efficient chemoenzymatic approach was developed for the preparative scale synthesis of complex tumor-associatedantigenN3minoroctasaccharide. The success of this approach relies on the highly efficient one-pot multi-enzyme based sequential enzymatic elongation of a chemically synthesized branched tetrasaccharide core structure.

O-Isopropylidene derivatives of sugars are readily prepared by using the Lewis acid and dehydrating agent triphenylphosphine polymer-bound/I 2 complex. This new method is characterized by smooth, non-equilibrating reaction conditions and a very clean, simple work-up, making it particularly suitable for O-isopropylidenation of sugars under mild conditions and with low environmental impact.
