title: Synthesis of pyridino[2,3-f]indole-4,9-dione and 6,7-disubstituted quinoline-5,8-dione derivatives and evaluation on their cytotoxic activity.
abstract: We report upon the synthesis of the following derivatives: N-substituted-pyridino[2,3-f]indole-4,9-dione, and 6-(alpha-diethoxycarbonyl-methyl)-7-substituted-amino-quinoline-5,8-dione, which contain the active quinoline-5,8-dione (VII) moiety. The cytotoxic activities of these compounds have been tested in SRB (SulfoRhodamine B) assays against the cancer cell lines of A-549 (human lung cancer), SK-MEL-2 (human melanoma cancer), SK-OV-3 (human ovarian cancer), XF-498 (human brain cancer) and HCT 15 (human colon cancer). The compound, N-benzyl-3-ethoxycarbonyl-2-hydroxy-pyridino[2,3-f]indole-4,9-dione (A-9), also showed higher activity than cis-platin. The highest level of cytotoxic activity in these human tumor cell lines was observed in the compound 6-(alpha-diethoxycarbonyl-methyl)-7-(2-methyl-phenylamino)-quinoline-5,8-dione (B-3).
