express a polysaccharide known as enterobacterial common antigen (ECA), which is an attractive target for the development of universally acting immunotherapies. The first chemical synthesis of ECA‐derived oligosaccharides for the development of such therapies is described. A number of synthetic challenges had to be addressed, including the development of concise synthetic procedures for unusual monosaccharides
所有肠杆菌科细菌都表达一种称为肠杆菌共同抗原(ECA)的多糖,它是开发通用免疫疗法的一个有吸引力的靶标。描述了用于开发此类疗法的 ECA 衍生寡糖的首次化学合成。必须解决许多合成挑战,包括开发不寻常单糖的简明合成程序、选择适当的正交保护基团、开发立体选择性糖基化方法、在Man p上引入羧酸基团的适当时机。 NAcA 部分,以及选择适当的条件来还原多个叠氮基部分。合成化合物用于揭示 ECA 的免疫显性部分。此外,还开发了一种与 ECA 结合的单克隆抗体 (mAb),可以选择性地识别多种肠杆菌科细菌。
