The synthesis of a range of novel bidentate and hexadentate ligands containing the chelating moiety 3-hydroxy-2(1H)-pyridinone is described. The pKa values of the ligands and the stability constants of their iron(III) complexes have been determined. The stability constant of the iron(III) complex of one of the hexadentate ligands is comparable to that of desferrioxamine B. The distribution coefficients
描述了一系列包含螯合部分3-羟基-2(1H)-吡啶酮的新颖的二齿和六齿配体的合成。已经确定了配体的pKa值及其铁(III)配合物的稳定性常数。六齿配体之一的铁(III)配合物的稳定性常数与去铁胺B相当。配体及其铁(III)配合物的分布系数也被确定。新型六齿化合物之一已显示出可显着增强肝细胞和铁超载小鼠的铁(III)排泄。
