inhibit the growth of pancreaticcancercells. The pKa of the leaving group at the 3-position was shown to influence growth inhibitory activity that is consistent with the proposed mechanism of action of reduction, loss of leaving group and formation of a reactive iminium species. Substitutions on the indole nitrogen were well tolerated with little influence on growth inhibitory activity while substitutions
吲哚醌对胰腺癌细胞的生长抑制活性的一个重要决定因素是在 2-位上被 2-未取代的衍生物取代,其效力明显更强。通过铜(II)介导的溴醌和烯胺的反应,然后进行官能团互变,制备了一系列在氮上和吲哚基羰基位置带有一系列取代基的吲哚醌。然后测定化合物抑制胰腺癌细胞生长的能力。p K a3-位离去基团的改变显示出影响生长抑制活性,这与所提出的还原作用机制、离去基团损失和反应性亚胺类物质的形成一致。吲哚氮上的取代具有良好的耐受性,对生长抑制活性几乎没有影响,而在大于甲氧基的 5 位和 6 位取代导致活性降低。提出的研究定义了最佳生长抑制活性所需的 2-未取代吲哚醌的取代范围。
