An N-linked pseudodisaccharide 2 containing an inositol moiety in place of a glycopyranosyl residue has been synthesised to mimic the disaccharide unit, 3-O-(α-D-glucopyranosyl)-D-glucopyranose, cleaved by glucosidase II during glycoprotein processing. Its inhibitory action towards yeast α-glucosidase was inferior to that of 1-deoxynojirmycin, a known inhibitor of glucosidase II. An attempt to prepare the analogous 2-N-linked compound 1 as an inhibitor of glucosidase I led to the novel N-phenyl derivative 11 of 2-amino-2-deoxy-D-glucopyranose.
一种含有肌醇部分代替糖苷残基的N-连接假二糖2已被合成,以模拟在糖蛋白加工过程中由糖基二酯酶II切割的二糖单元3-O-(α-D-葡萄糖苷基)-D-葡萄糖苷。2对酵母α-糖苷酶的抑制作用不如已知的糖基二酯酶II抑制剂1-脱氧野尻霉素。为了制备作为糖基二酯酶I抑制剂的类似2-N-连接化合物1,得到了2-氨基-2-脱氧-D-葡萄糖苷的新型N-苯基衍生物11。
