Page/Page column 7, (2010/04/23)
The present invention relates to methods for the preparation of pyridone carboxylic acids for use as intermediates in the preparation of various synthetic organic compounds. The pyridone carboxylic acids can for example be used as intermediates in the production of potent antitumor agents, antifungal agents, antiviral agents, psychotherapeutic agents or contrast imaging agents for MRI.

The synthesis of a range of novel bidentate ligands containing the chelating moiety 3-hydroxy-4(1H)-pyridinone is described. The pK(a) values of the ligands and the stability constants of their iron(III) complexes have been determined. The crystal structures of one of the ligands and one of the iron(III) complexes are presented. The distribution coefficients of the ligands are reported and are related to the ability of the ligands to remove iron from hepatocytes. The influence of 3-hydroxy-4(1H)-pyridinones on oxidative damage to cells is described. In contrast to the iron chelator in current therapeutic use, desferrioxamine-B, many of the bidentate ligands described in this study are orally active in iron-overloaded mice.
