Many monoclonal antibodies (mAbs) used in cancer immunotherapy mediate tumour cell lysis by recruiting natural killer (NK) cells; a phenomenon known as antibody-dependent cellular cytotoxicity (ADCC). Eliminating core-fucose from the N-glycans of a mAb enhances its capacity to induce ADCC. As such, inhibitors of fucosylation are highly desirable for the production of mAbs for research and therapeutic
癌症免疫疗法中使用的许多单克隆
抗体(mAb)通过募集天然杀伤(NK)细胞来介导肿瘤细胞裂解。一种称为
抗体依赖性细胞毒性(A
DCC)的现象。从mAb的N-聚糖中消除核心岩藻糖增强了其诱导A
DCC的能力。这样,岩藻糖基化
抑制剂对于生产用于研究和治疗用途的mAb是非常需要的。在本文中,我们描述了岩藻糖基化的代谢
抑制剂6,6,6-三
氟-1-岩藻糖(F3Fuc)的简单合成,并证明了该分子在从鼠杂交瘤
细胞系生产低岩藻糖mAb中的实用性。
