Two changes for the better: A novel class of sialic acid derivatives is prepared by modifying both the C‐4 and C‐9 positions of Neu5Aα2Me (see structure). This approach gives a lead compound that has sub‐micromolar affinity for Siglec‐2 and may provide a pathway for immunoglycotherapy strategies for autoimmune diseases and B cell derived non‐Hodgkin's lymphoma.
有两个更好的变化:通过修饰Neu5Aα2Me的C-4和C-9位置来制备一类新的唾液酸衍生物(请参见结构)。这种方法所产生的先导化合物对Siglec-2具有亚微摩尔的亲和力,并可能为自身免疫性疾病和B细胞源性非霍奇金淋巴瘤的免疫糖疗法策略提供途径。
