  Synthesis and toxicity towards normal and cancer cell lines of benzimidazolequinones containing fused aromatic rings and 2-aromatic ring substituents

  摘要：

  A facile 6-exo-trig cyclization of sigma-aromatic radicals has allowed the synthesis of various aromatic ring fused benzimidazoles and benzimidazolequinones. The most highly conjugated naphthyl fused benzimidazolequinone, (5-methyl-5,6-dihydrobenzimidazo[2,1-a]benzo[f]isoquinoline-8,11-dione) showed the highest specificity towards human cervical (HeLa) and prostate (DU145) cancer cell lines with little toxicity towards a human normal (GM00637) cell line at doses of <1 mu M. In contrast, 2-aromatic ring substituted (benzimidazole-4,7-diones) analogues, benzimidazolequinone with a pyridine ring and mitomycin C were more toxic than the highly conjugated naphthyl fused benzimidazolequinone towards the normal cell line.
