the hydroxyamidine 20 upon reaction with hydroxylamine. The new paullones were tested both in a CDK1/cyclin B inhibition assay and in the in vitro antitumor cell line-screening program of the National Cancer Institute (NCI). With respect to the CDK1/cyclin B inhibition, electron-withdrawing substituents in the 9-position as well as a 2,3-dimethoxy substitution on the paullone basic scaffold turned out
丹参酮代表一类新的小分子细胞周期蛋白依赖性激酶(CDK)抑制剂。为了研究结构活性关系并开发具有抗肿瘤活性的paullones,先导结构kenpaullone(9-bromo-7,12-dihydroindolo [3,2-d] [1] benzazepin-6(5H)-one,4a )合成。通过1s- [1]苯并ze庚因-2,5(3H,4H)-二酮5的Fischer吲哚反应制备在2、3、4、9和11位具有不同取代基的泡龙。通过分别在氢化钠/ THF或氢氧化钾/丙酮的存在下用烷基卤化物处理肯保隆来实现内酰胺或吲哚氮原子上的选择性取代。kenpaullone衍生的硫内酰胺18的S-甲基化产生了甲基硫代亚氨酸19,与羟胺反应后得到羟基am20。新的paullones在CDK1 / cyclin B抑制试验和美国国家癌症研究所(NCI)的体外抗肿瘤细胞株筛选程序中均进行了测试。关于CDK1 /细胞
