Abstract
The cytotoxicities of pyridino[2,3-f]indole-4,9-dione derivatives were examined against human lung tumor cell lines (A 549), human ovarian tumor cell lines (SK-OV-3), human melanoma tumor cell lines (SK-MEL-2), human CNS tumor cell lines (XF 498) and human colon tumor cell lines (HCT 15) in vitro using a Sulforhodamine B assay. 3-Ethoxycarbonyl-1-(2-methoxyethyl)-2-methyl-1H-pyridino[2,3-f]ind ole-4,9-dione (5) showed excellent cytotoxicity against XF 498 and HCT 15. The ED50 values of 5 were 0.006 microg/ml against XF 498 and 0.073 microg/ml against HCT 15, while those of doxorubicin were 0.012 and 0.264 microg/ml, respectively. 1-Benzyl-3-ethoxycarbonyl-2-methyl-1H-pyridino[2,3-f]indole-4,9-di one (7) (ED50 value 0.065 microg/ml) was also significantly more cytotoxic against HCT 15 compared with doxorubicin.
