The synthesis and antitumor activity of substituted benzo[e][1,2,4]triazino[2,3-c][1,2,3]triazin-2-ones-novel electro-deficient tricyclic compounds-are described. These compounds were prepared by treatment of 3-(2-amino-3-R2-5-R3-phenyl)-6-R1-1,2,4-triazin-5(2H)-ones with sodium nitrite in acetic acid. Spectral properties of synthesized compounds were studied and compared with spectral data of known 3-R-8-R1-10-R2-2H-[1,2,4]triazino[2,3-c]quinazolin-2-ones. These compounds are promising antitumor agents. The most active anticancer compound 3d was studied in dose-depended anticancer activity assay and its selective growth inhibition against breast cancer MDA-MB-468 cell line was established (GI50=0.41 μm).
