3-Ethoxycarbonyl-3-methyl-N-substituted-2,3-dihydro-benz[f]indole-2,4,9-trione [9(a-d)] and 3-ethoxycarbonyl3-methyl-N-substrituted-2,3-dihydro-benz[j]indole-2,4,9-trione [10(a-i)] derivatives were synthesized from 7-chloro-6-(1,1-diethoxycarbonyl-ethyl)-5,8-quinolinedione (7) and 2-chloro-3-(1,1-diethoxycarbonyl-ethyl)-1,4-naphthoquinone (8), respectively, using a variety of alkyl- and arylamines. The cytotoxic activities of the synthesized compounds were evaluated by a Sulforhodamine B (SRB) assay against the following tumor cell lines: A459 (human non-small cell lung), SK-OV-3 (human ovarian), SK-MEL-2 (human melanoma), XF498 (human CNS), and HCT 15 (human colon). Almost all the derivatives mentioned above had a more potent cytotoxic effect against SK-OV-3 than etoposide. In particular, 3-ethoxycarbonyl-3-methyl-N-(4-aminophenyl)-2,3-dihydrobenz[f]indole-2,4,9- trione (10h) exhibited greater activity against all the tumor cell lines, and its cytotoxic effect against SK-OV-3 was especially higher than doxorubicin.
