We describe the design and synthesis of a trivalent CD22 ligand conjugated with a trivalent nitrophenol (ligand for decameric anti-nitrophenol immunoglobulin M). To generate such a bifunctional ligand, we designed and prepared two synthetic building blocks possessing different terminal functionalities. Coupling of these compounds afforded a trivalent azide-terminated scaffold. Ligation of the scaffold with an alkyne-terminated CD22 ligand by the use of click chemistry afforded the target trivalent cluster. We anticipate that our ligand will be valuable in a variety of applications, including targeting B cells and modulation of the humoral immune response.
我们描述了与三价硝基苯酚(十聚抗硝基苯酚免疫球蛋白 M 的配体)缀合的三价 CD22 配体的设计和合成。为了生成这样的双功能配体,我们设计并制备了两种具有不同末端功能的合成结构单元。这些化合物的偶联提供了三价叠氮化物封端的支架。通过使用点击化学将支架与炔烃封端的 CD22 配体连接,得到目标三价簇。我们预计我们的配体将在多种应用中发挥价值,包括靶向 B 细胞和调节体液免疫反应。
