We report the synthesis of a nucleic acid-encoded carbohydrate library, its combinatorial self-assembly into 37 485 pairs and a screen against DC-SIGN leading to the identification of consensus ligand motifs. A prototypical example from the selected pairs was shown to have enhanced binding. A dendrimer incorporating the selected motifs inhibited gp120's binding to dendritic cells with higher efficiency than mannan.
我们报告了核酸编码的
碳水化合物文库的合成,其组合自组装成37,485对,并针对DC-SIGN进行筛选,从而确定了共识
配体基序。从选定的配对中,我们展示了一个原型示例,其结合能力得到了增强。一种包含选定基序的树状大分子抑制了gp120与树突状细胞的结合,其效率高于
甘露聚糖。
