The most widely investigated for medicinal applications are the 3-hydroxy-4-pyrones and the 1,2- 3,2- and 3,4-hydroxypyridinones. Key features of these ligands are: a six-membered ring, with a ring N or O atom either ortho or para to a ketone group, and two ortho exocyclic oxygen atoms. Readily functionalizable, the hydroxypyrones and hydroxypyridinones allow one to achieve a range of di- and trivalent metallocomplex stabilities and can include tissue or molecular targeting features by design. Research over the past several decades has greatly expanded the array of ligands that are the subject of this critical review. Ligand applications as diverse as iron removal or supplementation, contrast agents in imaging applications, and mobilization of undesirable excess metal ions will be surveyed herein.}, keywords = {DIELS-ALDER REACTION, ENHANCED PFE(3+) VALUES, ETHYL MALTOL, evaluation, IN-VIVO, ION SEQUESTERING AGENTS, IRON-DEFICIENCY ANEMIA, MONOLAYERS, MRI CONTRAST AGENTS, ORAL, RAT SMALL-INTESTINE, SELF-ASSEMBLED, VANADYL SULFATE}, isbn = {0306-0012}, url = {://000237903700006}, author = {Thompson, K.
