The bis derivative 6 of 8-hydroxyquinoline, which, like tropolones, readily forms a chelate, was synthesized and found to have high potency (dose = 12.5 mg/kg, T/C % = 164) against leukemia P388 in mice approximately equivalent to that of the bistropolone 1b. 8-Hydroxyquinoline analogues with broad structural variation were synthesized and their structure-activity relationships followed the same pattern
合成了8-羟基喹啉的双衍生物6,与对苯二酚一样,很容易形成螯合物,并发现它在小鼠中对白血病P388具有很高的效力(剂量= 12.5 mg / kg,T / C%= 164),相当于双酚A酮1b。合成了具有广泛结构变化的8-羟基喹啉类似物,其结构活性关系遵循与托酚酮系列相同的模式。此外,对双tropolones 1a-e结合微管蛋白的能力进行了测试,发现没有这种性质。这项研究的结果表明,双曲酮和双(8-羟基喹啉)衍生物必须与该酶所需的金属(如核糖核苷酸还原酶)形成螯合物,从而催化DNA的生物合成途径。
