We report the synthesis of a series of bivalent 1,2,3-triazole linked galactopyranosides as potential inhibitors of cholera toxin (CT). The inhibitory activity of the bivalent series was examined (ELISA) and the series showed low inhibitory activity (millimolar IC50s). Conversely, the monomeric galactotriazole analogues were strong inhibitors of cholera toxin (IC50 = 71–75 μM).
我们报道了一系列以1,2,3-三氮唑连接的二价半乳糖吡喃糖苷的合成,这些化合物可能作为霍乱毒素(CT)的抑制剂。对二价系列的抑制活性进行了检测(ELISA),结果显示其抑制活性较低(毫摩尔级别的IC50值)。相反,单体的半乳糖三氮唑类似物对霍乱毒素具有较强的抑制作用(IC50值为71-75微摩尔)。
