The synthesis of some new tetrahydroquinolines, tetrahydropyrimido[4,5-b]quinolines, and tetrahydropentaazacyclopenta[a]anthracenes structurally related to some DNA intercalators is described. Fifteen compounds were evaluated for their antitumor activity by the National Cancer Institute (NCI), in vitro disease oriented antitumor screening. The most active tricyclic pyrimido[4,5-b]quinolines 3b, 6b
描述了一些新的四氢喹啉,四氢嘧啶基[4,5- b ]喹啉和四氢戊基氮杂环戊达[ a ]蒽的合成,这些结构与某些DNA嵌入剂有关。美国国家癌症研究所(NCI)评估了15种化合物的抗肿瘤活性,进行了体外疾病定向抗肿瘤筛选。最活跃的三环嘧啶并[4,5- b ]喹啉3b,6b,7b和8b进一步进行了DNA结合研究,以使它们的活性合理化。化合物8b从其对某些单个细胞系的显着生长抑制潜力以及广泛的抗肿瘤活性(分别为GI 50,TGI和LC 50值分别为46.9、85.3和97.4)证明,它被证明是该研究中最活跃的成员。具有良好的DNA结合亲和力。
