Oligoarabinofuranosides 1−4, fragments of the arabinan components found in the mycobacterial cell wall have been synthesized. 1 and 2 are representative of the structural features of the internal core of arabinogalactan, arabinomannan and lipoarabinomannans. 3 is the capping motif of the lipoarabinomannan of Mycobacterium tuberculosis and M. bovis BCG while 4 is the hexasaccharide found at the non-reducing
Oligoarabinofuranosides 1-4,在分枝杆菌细胞壁中发现的阿拉伯聚糖成分的片段已被合成。图1和2代表了阿拉伯半乳聚糖、阿拉伯甘露聚糖和脂阿拉伯甘露聚糖的内部核心的结构特征。3 是结核分枝杆菌和牛分枝杆菌 BCG 的脂阿拉伯甘露聚糖的加帽基序,而 4 是在阿拉伯半乳聚糖的非还原端发现的六糖。对阿拉伯呋喃糖苷单元之间糖苷键的形成实现了完全立体控制:α-糖苷通过在 2-位上的酯或碳酸酯基团的参与获得,而 β-阿拉伯呋喃糖苷通过内部苷元传递方法获得。(© Wiley-VCH Verlag GmbH & Co.
