Benzo[c]phenanthridine skeleton was synthesized from easily available starting N-methyl-o-toluamide 2 and o-methylbenzonitrile 5 in 7 steps. Radical cyclization of styrene 10 afforded 6, 11-dimethyl-6, 11 -dihydro-5H-in-deno[1, 2-c]isoquinolin-5-one 13. Most 3-arylisoquinolines have displayed strong activities against human tumor cell lines. Especially, indenoisoquinolinone 13 exhibited excellent cytotoxicity (IC50=0.002 μg/ml; HCT 15).
苯并[c]菲啰啉骨架是通过7个步骤由易得的起始物N-甲基-o-苯甲酰胺2和o-甲基苯腈5合成的。苯乙烯10的自由基环化反应生成了6, 11-二甲基-6, 11-二氢-5H-隐苯并[1, 2-c]异喹啉-5-酮13。大多数3-芳基异喹啉对人类肿瘤细胞系表现出了强烈的活性。特别是,隐喹啉酮13表现出优异的细胞毒性(IC50=0.002 μg/ml;HCT 15)。
