In order to develop a generic treatment for infections with Gram- negative bacteria, we developed a synthesis of 2-acylamino-deoxynojirimycin derivatives (17, 18, 19 and 20), which will be used as haptens for raising catalytic antibodies capable of hydrolyzing the interglycosidic bond in the lipid A moiety of endotoxins. A key intermediate in the preparation of compounds 17, 18; 19 and 20 is 3,4,6-tri-O-benzyl-2-
为了开发革兰氏阴性菌感染的通用治疗方法,我们开发了 2-酰氨基-脱氧野尻霉素衍生物(17、18、19 和 20)的合成物,将用作半抗原,用于产生能够水解革兰氏阴性菌的催化抗体。内毒素脂质 A 部分的糖苷间键。制备化合物17、18的关键中间体;19和20是3,4,6-三-O-苄基-2-[(苄氧羰基)氨基]-2-脱氧-D-葡糖酸-δ-内酰胺(6),其由已知的3,4,6制备-tri-O-benzyl-2[(benzyloxycarbonyl)amino]-2-deoxy-D-glucosamine (1) 分四步,总产率为 47%。抗体是针对 2-[(6- 氨基己酰基) 氨基]-2-脱氧-D-葡糖酸-δ-内酰胺 (17) 偶联到载体蛋白牛血清白蛋白产生的。
