Abstract

Conjugates of 2,4-diamino sugars and uridine have been synthesized as galactosyltransferase inhibitors. The relationship between inhibitory activity and the chelation abilility of the hinge-like diamino sugar towards a metal ion was studied by NMR spectroscopy. One of the conjugates exhibited a moderate inhibition that ranks between those of UDP and UMP probably through the chelation of the hinge-like diamino sugar to MnII. (© Wiley-VCH Verlag GmbH & Co.
