4-Hydroxy-5-methyl-3-pyridinecarboxylic acid (DQ5) and 4-hydroxy-1,5-dimethyl-3-pyridinecarboxylic acid (DQ715) were evaluated for Fe and Al chelation therapy. Metal/ligand solution chemistry, electrochemistry, cytotoxicity and chelation efficiency in vitro were studied. DQ715 is a chelator for both metal ions, whereas DQ5 is more suitable as a selective Al chelator.
