inhibitors of fucosylation have shown promise as therapeutic agents for sickle cell disease, arthritis, and cancer. We describe here the design and synthesis of a panel of fluorinated l-fucose analogs bearing fluorine atoms at the C2 and/or C6 positions of l-fucose as metabolic fucosylation inhibitors. Preliminary study of their effects on cell proliferation revealed that the 6,6-difluoro-l-fucose (3) and
岩藻糖基化是糖蛋白N和O聚糖最普遍的修饰之一,在各种细胞过程和疾病中起着重要作用。岩藻糖基化的小分子抑制剂已显示出有望作为镰状细胞疾病,关节炎和癌症的治疗剂。我们在这里描述了一组在代谢产物岩藻糖基化抑制剂中在1-岩藻糖的C2和/或C6位置带有氟原子的氟化1-岩藻糖类似物的设计和合成。对它们对细胞增殖的影响的初步研究表明,6,6-二氟-1-岩藻糖(3)和6,6,6-三氟-1-岩藻糖(6)显示出对人结肠癌细胞和人脐静脉内皮细胞增殖的显着抑制活性。相反,先前报道的2-脱氧-2-氟-1-岩藻糖(1)对所有测试的细胞系的增殖没有明显影响。为了了解氟化1-岩藻糖类似物抑制细胞增殖的机制,我们对相应的GDP氟化1-岩藻糖类似物进行了化学合成,并测试了它们对哺乳动物α1,6-岩藻糖基转移酶(FUT8)的抑制活性。有趣的是,6,6-二氟-1-岩藻糖(3)和6,6,6-三氟-1-岩藻糖(6)是更强的增殖抑制剂
