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.

AbstractA series of N‐(phosphonacetyl)amine derivatives were synthesized and screened for plant‐growth regulating activity on Lepidium sativum L. and Cucumis sativus L. Aromatic N‐(phosphonoacetyl)amines. which may be considered as possible analogues of N‐acylaniline herbicides obtained by replacement of their acyl group by the phosphonacetyl moiety, exhibited significant or moderate herbicidal activity. In contrast, N‐(phosphonoacetyl)amino acids and N‐(phosphonoacetyl)aminophosphonic acids promoted the growth of L. sativum and C. sativus roots.
