A variety of glycoconjugates bearing either N-acetyllactosamine or sialyl Lewisx units have been synthesised in a chemo-enzymatic way. This includes the synthesis of glycopolymer copolymerised with acrylamide and whose glucosamine unit was substituted with different kinds of side-chain. Glycopeptides with different spacer-arm glucosamine units have also been prepared and polymerised. The sugar chain
已经以化学酶促的方式合成了各种带有N-乙酰基乳糖胺或唾液酸化的Lewis x单元的糖缀合物。这包括与丙烯酰胺共聚的糖聚合物的合成,其糖胺单元被不同种类的侧链取代。还已经制备并聚合了具有不同间隔臂葡糖胺单元的糖肽。然后使用糖基转移酶拉长糖链,以提供新的连续糖肽。在这些情况下,聚合糖簇效应导致高效的酶促糖基化。然而,根据用于每种底物的反应条件,已经注意到一些差异。
