Symmetric Tröger’s base derivatives with quinolinium substitution, 7 and 8, were prepared, and their structures were confirmed by 1H and 13C NMR, 2D NMR and NOE NMR techniques and elemental analysis. These compounds were studied as specific ligands for the recognition of glycosaminoglycans (heparin, heparan sulphate, chondroitin sulphate and hyaluronic acid). They exhibited high affinity and selectivity
制备了具有喹啉取代基的对称Tröger碱基衍生物7和8,并通过1 H和13证实了其结构C NMR,2D NMR和NOE NMR技术以及元素分析。研究了这些化合物作为识别糖胺聚糖(肝素,硫酸乙酰肝素,硫酸软骨素和透明质酸)的特异性配体。它们对糖胺聚糖,特别是肝素表现出高亲和力和选择性。条件结合常数,线性范围和检测限通过紫外可见光谱法测定。这些值,特别是在极低的检测限下,表明所制备的配体具有识别和测定糖胺聚糖,特别是肝素的巨大潜力。例如, 在培养基(1 mM NaCl(H)中,7和8的最低可检测肝素浓度为0.1和0.17 ng / mL(R 2 = 0.988和0.9938)2 O:MeOH; 7:3,v / v),pH = 7.34)。
