Pyridoxal isonicotinoylhydrazone (PINH; 1) and its isomeric O-acetates (E and Z) were synthesized and complexed with ferrous ions to afford the hitherto unisolated chelates iron(II) bis(pyridoxal isonicotinoylhydrazone)s (11) and iron(II) bis(O-acetylpyridoxal isonicotinoylhydrazone)s (12). The analytical and spectroscopic data of the new coordination compounds are presented. In addition, a series
合成了吡rid醛异烟酰yl(PINH; 1)及其异构体O-乙酸盐(E和Z),并与亚铁离子络合,从而获得了迄今未分离的螯合物铁(II)双(吡rid异烟酰yl)(11)和铁(II)双(O-乙酰基吡啶氧基异烟酰yl)(12)。介绍了新的配位化合物的分析和光谱数据。此外,已经制备了一系列结构2-3和5-10的吡ido醛的亚氨基衍生物,并在体内作为储存铁的螯合剂进行了测试,并估算了尿中和粪便中放射性铁的累积净排泄量。这项研究重新确立了PINH是一种有效的体内铁螯合剂,其功效与肠胃外去铁胺(DF)相当,并表明它需要进一步关注。
