Human breast cancer T47D cells were cultured in RPMI 1640 complete culture medium and exposed for 48 h to different concentrations of newly synthesized quinoline derivatives [SRA-HX-(1-3) and SRA-BQ] and also to ADR, VCR, VP16 and TAM. A dose-dependent decrease in cell proliferation was observed following exposure to almost all synthesized quinolines. The highest cytotoxicity was seen at 1x10-4M concentration of SRA-HX-3 that was near to growth inhibitory effect of ADR (1x10-6M) and significantly (p<0.002) greater than VCR, VP16 and TAM (each at 1x10-6M). The other 3 compounds (1x10-4M) had similar activity to VCR that was less than ADR and significantly (p<0.002) greater than VP16 and TAM. Therefore, new cytotoxic quinolines are potentially good candidates for further investigation as anti-tumor compounds.]]>Abel, M.D., H.T. Luu, R.G. Micetich, D.Q. Nguyen and M.
