Cytotoxic effects of quinoxaline derivatives on human cancer cell lines.
The cytotoxicities of 6,7-modified-5,8-quinoxalinedione derivatives and heterocyclic quinoxaline derivatives containing nitrogen, sulfur, and oxygen on human lung adenocarcinoma cell (PC 14), human gastric adenocarcinoma cell (MKN 45), and human colon adenocarcinoma cell (colon 205) were examined in vitro using MTT assay. Pyrido[1,2-a]imidazo[4,5-g]quinoxaline-6,11-dione (10) was markedly cytotoxic against MKN 45 compared with adriamycin and cis-platin used as anticancer drugs. The IC50 value of compound 10 was 0.073 microM while those of adriamycin and cis-platin were 0.12 microM and 2.67 microM, respectively.
