Abstract
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).
摘要
本文描述了取代的苯并[e][1,2,4]三嗪[2,3-c][1,2,3]三嗪-2-酮——一种新型的电缺三环化合物的合成和抗肿瘤活性。这些化合物是通过将3-(2-氨基-3-R2-5-R3-苯基)-6-R1-1,2,4-三嗪-5(2H)-酮与乙酸的硝酸钠处理而制备的。研究了合成化合物的光谱特性,并与已知的3-R-8-R1-10-R2-2H-[1,2,4]三嗪[2,3-c]喹唑啉-2-酮的光谱数据进行了比较。这些化合物是具有前景的抗肿瘤剂。在剂量依赖性抗肿瘤活性试验中研究了活性最高的抗肿瘤化合物3d,并确定了其对乳腺癌MDA-MB-468细胞系的生长抑制具有选择性(GI50=0.41 μm)。
