The substituted pyridazino[4,5-b]phenazine-5,12-diones and tri/tetra-azabenzo[a]fluorene-5,6-diones were synthesized from 6,7-dichlorophthalazine-5,8-dione and 6,7-dichloroquinoline-5,8-dione, respectively. The cytotoxic activities of the prepared compounds were evaluated by an SRB (Sulforhodamine B) assay against the following human cancer cell lines: A549 (lung), SK-OV-3 (ovarian), SK-MEL-2 (melanoma), XF 498 (CNS), and HCT 15 (colon). Almost all synthesized pyridazino[4,5-b]phenazine-5,12-diones (7a-j) presented higher cytotoxicity than that of doxorubicin (IC(50)=0.097-0.225 microM) against the cancer cell lines. In particular, the cytotoxicity of compounds 7f (R(1)=Et) and 7h (R(1), R(2)=Me) against all human cancer cell lines examined was about 10 times higher than that of doxorubicin. However, the cytotoxicities of several synthesized azabenzo[a]fluorene-5,6-diones (12a, 12c, 12d, 12e, and 12g) against the cancer cell lines in vitro were comparable to those of doxorubicin.
