Rapid one-pot synthesis of alkane-α ω, diylbisphosphonic acids from dihalogenoalkanes under microwave irradiation

A one-pot, two-step synthesis of alkylenebisphosphonic acids from dihalogenoalkanes was performed under microwave irradiation. The reaction is very rapid and convenient for the synthesis of small samples of alkylenebisphosphonic acids. Copyright Taylor & Francis Group, LLC.

The synthesis of novel bisphosphonates as inhibitors of phosphoglycerate kinase (3-PGK)

A series of conformationally-restrained analogues of 1,3-bisphospho-D-glyceric acid (1,3-BPG) 1 has been synthesised for use as inhibitors of 3-PGK (E.C. 2.7.2.3). These compounds have non-scissile phosphonate linkages and also incorporate α-halogen substituents to make them isopolar and isosteric mimics of the natural substrate. A monocyclic aryl core between the two phosphoryl centres provides both a rigid framework linking these moieties and loci for further substitution. The compounds were tested against human 3-PGK and found to be good competitive inhibitors. α-Fluorination of the phosphonic acids increased the affinity for the enzyme into the submicromolar range. Correlation of IC50 data with pKa. and pKa, values indicates that the acidity of the phosphoryl group exerts a strong influence on protein binding. The Royal Society of Chemistry 2000.
