Several 2-amino-pyrimido[4,5-c]quinolin-1(2H)-ones variously substituted at positions 3, 5, and 9 were prepared from their corresponding lactones. The target compounds were investigated for in vitro cytotoxic activity against a panel of human cancer cell lines, namely, lung fibrosarcoma HT-1080, colon adenocarcinoma HT-29, and breast carcinoma MDA-MB-231. Analysis of data revealed that the presence
由它们相应的内酯制备在位置3、5和9上被不同取代的几个2-氨基-嘧啶基[4,5-c]喹啉-1(2H)-。研究了目标化合物对一组人类癌细胞系,即肺纤维肉瘤HT-1080,结肠腺癌HT-29和乳腺癌MDA-MB-231的体外细胞毒性活性。数据分析显示,位置9处的氯气对细胞毒性活性具有重要的积极影响。在3-苯基对位的额外卤素取代进一步增强了活性。此外,发现化合物(25)剂量依赖性地抑制微管蛋白聚合。因此,最有效的化合物(23-26)的流式细胞仪分析表明,所测试的化合物诱导了G(2)/ M期的细胞周期停滞。
