Abstract Three novel iron chelators namely the 1-methyl-, 1-ethyl- and 1-propyl-2-ethyl-3-hydroxypyrid-4-ones were prepared in high yields from ethyl maltol and the related alkylamine in a one step reaction. These chelators formed 3 chelator:1 iron stable, coloured, neutral complexes at physiological pH and mobilise iron from transferrin, ferritin and haemosiderin. The rate of iron mobilisation from
摘要用一步法从乙基麦芽酚和相关的烷基胺中高收率地制备了三种新型的铁螯合剂,即1-甲基-,1-乙基-和1-丙基-2-乙基-3-羟基吡啶-4-酮。这些螯合剂形成3种螯合剂:1在生理pH值下稳定的,有色的铁中性复合物,并从运铁蛋白,铁蛋白和血铁蛋白中动员铁。这些蛋白质的铁动员速率为转铁蛋白>血铁蛋白>铁蛋白。1-烷基-2-乙基-3-羟基吡啶-4-酮在生理pH下的廉价合成和强铁结合特性需要进一步研究和开发这些化合物及其同系物,以治疗铁超负荷和铁过剩。铁的其他疾病失衡和毒性。
