  Highly Potent Bisphosphonate Ligands for Phosphoglycerate Kinase

  摘要：

  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.
