The synthesis of a range of novelbidentateligandscontaining the chelating moiety 3-hydroxy-4(1H)-pyridinone is described. The pKa 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

Pharmaceutical compositions containing an iron complex of a 3-hydroxypyrid-2-one or 3-hydroxypyrid-4-one in which the hydrogen atom attached to the nitrogen atom is replaced by an aliphatic hydrocarbon group and, optionally, in which one or more of the hydrogen atoms attached to ring carbon atoms are also replaced by an aliphatic hydrocarbon group, are of value for the treatment of iron deficiency anemia.

A range of hexadentate 3‐hydroxypyridin‐4‐ones (HPOs) with high affinity for iron(III) has been synthesized. The log stability constants of two HPO–iron complexes (logK1) were determined to be over 34, and pFe values of the two HPOs were determined to be over 31. Antimicrobial assay indicated that they are able to markedly inhibit the growth of both Gram‐positive and Gram‐negative bacteria. Compounds 14a and 14e were found to exhibit the strongest inhibitory activity against Staphyloccocus aureus, Bacillus subtilis, Pseudomonas aeruginosa, and Escherichia coli, with MIC values of 8, 8, 16, and 8 μg/mL, respectively. These results indicate that hexadentate 3‐hydroxypyridin‐4‐ones have potential application as antimicrobial agents, especially in the treatment of wound infection.
