摘要:
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。

There is a need for fast detection methods for the banned rodenticide tetramethylenedisulfotetramine (TETS), a highly potent blocker of the γ‐aminobutyric acid (GABAA) receptors. Generalsynthetic approach toward two groups of analogues was developed. Screening of the resulting library of compounds by FLIPR or whole‐cell voltage‐clamp revealed that, despite the structural differences, some of the TETS
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.
