Multivalent antagonists able to reach the four carbohydrate recognition domains (CRD) of DC-SIGN have been prepared. The extended rigid core of these glycodendrimers allows multivalent presentation of glycomimetic molecules in a spatially defined fashion, providing high affinity towards DC-SIGN and selectivity over other C-type lectins featuring distinct CRD arrangements. The constructs successfully
已经制备了能够到达 DC-SIGN 的四个
碳水化合物识别域 (CRD) 的多价拮抗剂。这些糖树枝状大分子的延伸刚性核心允许以空间定义的方式多价呈现拟糖分子,提供对 DC-SIGN 的高亲和力和优于其他具有不同 CRD 排列的 C 型凝集素的选择性。该构建体成功地抑制了 DC-SIGN 与
SARS-CoV-2 刺突蛋白的结合以及 DC-SIGN 介导的埃博拉病毒转染。
