  α(1-3)-Galactosyltransferase Inhibition Based on a New Type of Disubstrate Analogue This work was supported financially by the Deutschen Forschungsgemeinschaft and the Fonds der Chemischen Industrie.

  摘要：

  How do retaining glycosyltransferases function? To answer this question, UDP-Gal and galactose were covalently linked to form disubstrate analogues 1, of which surprisingly 1β and not 1α inhibited α(1-3)-galactosyltransferases very well. An understanding of this inhibition is a key to the pharmacological prevention of hyperacute rejection in pig to primate xenotransplantation.
