The synthesis of oligomeric glycocomimetics has been performed for targeting the Pseudomonas aeruginosa PA-IIL lectin, which is of therapeutical interest for anti-adhesive treatment. The disaccharide alpha-L-Fucp-(1-->4)-beta-D-GlcNAc, which is a high-affinity ligand of the lectin, has been coupled to dimeric and trimeric linkers with various lengths and geometries. A series of linear dimers displayed
寡聚糖代谢物的合成已经针对
铜绿假单胞菌PA-IIL凝集素进行了靶向,这对于抗粘连治疗具有治疗意义。作为凝集素的高亲和力
配体的二糖α-L-Fucp-(1→4)-β-D-GlcNAc已与具有不同长度和几何形状的二聚体和三聚体连接体偶联。一系列线性二聚体显示出有效的聚集效应和非常强的亲和力,解离常数较低,为90 nM。该三聚体化合物在抑制测定中效率较低,但在溶液中显示出高亲和力。滴定微量热法和分子模型可以对结合数据进行深入分析和合理化。
