A series of new 2-oxo-1,4-disubstituted-1,2,5,6-tetrahydro-benzo[h]quinoline-3-carbonitriles supported with various pharmacophoric functionalities at position-1 is described. N-formyl, N-nitroso, N-arylthiocarbamoyl, N-alkyl, N-sulfonyl, and N-acetyl derivatives, 5–10 were prepared. A novel fused triazole series was also prepared. The in vitro anticancer activity of twenty synthesized compounds, 4a, 4b, 7a2, 7b2 and 8b1 showed considerable cytotoxic activity against the three tested human tumor cell lines. Compounds 7a2 and 7b2 proved to be the most active with special effect against the human colon carcinoma HT29 and human breast cancer MCF 7 cell lines. Compounds 7b2 and 7f2 also exhibited significant antivirus activity against hepatitis-C virus.
描述了一系列新型 2-氧代-1,4-二取代-1,2,5,6-四氢-苯并[h]喹啉-3-甲腈,在 1 位具有各种药效团功能。制备了 N-甲酰基、N-亚硝基、N-芳基硫代氨基甲酰基、N-烷基、N-磺酰基和 N-乙酰基衍生物 5-10。还制备了新型稠合三唑系列。 20 种合成化合物 4a、4b、7a2、7b2 和 8b1 的体外抗癌活性对三种测试的人类肿瘤细胞系显示出相当大的细胞毒活性。化合物7a2和7b2被证明是活性最强的,对人结肠癌HT29和人乳腺癌MCF 7细胞系有特效。化合物7b2和7f2还表现出显着的针对丙型肝炎病毒的抗病毒活性。
