Abstract: A range of close analogues of deferiprone have been synthesised. The group includes mono-, di- and tri-methyl-3-hydroxy-4(1H)-pyridones. These compounds were found to possess similar pFe(3+) values to that of deferiprone, with the exception of the 2.5-dimethylated derivatives. Surprisingly the NH-containing hydroxy-4(1H)-pyridones were found to be marginally more lipophilic than the corresponding N-Me containing analogues. This same group are also metabolised less efficiently by Phase 1 hydroxylating enzymes than the corresponding N-Me analogues. As result of this study, three compounds have been identified for further investigation centred on neutropenia and agranulocytosis.
