使用基于蒽二脒二膦酸和单-膦酸衍生物的荧光检测1进行了研究。的二脒1种形式1:1和1:2个络合物分别与二膦酸和单-膦酸衍生物,并呈现出蓝色荧光(λ EM 中的DMSO溶液= 432-442纳米)。脒鎓膦酸酯(复合物形成)和离解amidinum的形成(λ EM = 468纳米作为宽带)通过在荧光波长的差异区分,并且通过DOSY NMR光谱和TD-DFT计算证实。与二am 1形成1:2络合物 提出了在甲基膦酸之间具有另外的分子间氢键的甲基膦酸。

We have synthesized a series of novel analogs of 1,3-bisphospho-D-glyceric -acid, 1,3-BPG,(3) and evaluated their binding to phosphoglycerate kinase, PGK (EC 2.7.2.3). Nonscissile methane-phosphonic acids replace the two phosphate monoesters of 1,3-BPG and lead to several stable, tight-binding mimics of this intermediate species in glycolysis. Multiple fluorine substitution for hydrogen in the alpha-methylene groups of the phosphonic acid 1,3-BPG analogs markedly improves their binding to PGK as determined by NMR analysis. The best ligands bind some 50-100 times more strongly than does the substrate 3-phospho-D-glyceric acid and show a requirement for PKa3 to be generally below 6.0, while the presence of a beta-carbonyl group seems to be of secondary importance.
