natural target. Four monovalent and one divalent alpha-fucosyl amides have been tested for their affinity for a fucose-binding lectin from Pseudomonas aeruginosa. Isothermal calorimetric titrations demonstrated that they bind to the lectin in the micromolar range, with highest affinity for the divalent ligand. Molecular modelling established that, compared to Omicron-fucoside compounds, the glycomimetic
细菌与人糖缀合物的粘附可被与天然靶标竞争的可溶性糖模拟物抑制。已经测试了四种单价和一种二价的α-岩藻糖酰胺与
铜绿假单胞菌的岩藻糖结合凝集素的亲和力。等温滴定表明,它们在微摩尔范围内与凝集素结合,对二价
配体具有最高的亲和力。分子建模证实,与Omicron-岩藻糖苷化合物相比,拟糖酰胺基团导致
水桥氢键的丧失,而糖苷配基与蛋白质表面的额外接触可以部分补偿。
