Efficient Sialyltransferase Inhibitors Based on Transition-State Analogues of the Sialyl Donor
摘要:
A 200- to 1000-fold higher affinity for sialyltransferase is shown by compounds 1 and 2 relative to the natural substrate. These inhibitors, which are derived from the transition state of SN 1-type sialyltransfer, contain a flat ring that is attached through a carbon atom with a phosphonate and a cytidine monophosphate group.

A Nafion® resin‐supported oxovanadium(IV) catalyst was readily prepared via ion‐exchange method. This solid vanadyl perfluorinated sulfonate catalyst was used as an efficient and recoverable catalyst for the hydrophosphonylation of various aldehydesundersolventlessconditions at room temperature. The catalyst could be recovered by simple filtration and reused without a significant loss of activity
