A 30-membered piperidine ring-fused aromatic sulfonamide library was synthetized, including N-arylsulfonyl
1,2,3,4-tetrahydroquinolines, 1,2,3,4-tetrahydroisoquinolines and 2,3,4,9-tetrahydro-1H-pyrido[3,4-b]indoles. The compounds
induced oxidative stress and glutathione depletion in HT168 melanoma and K562 leukemia cells and in micromolar
concentrations exerted cytotoxic effects. Among the tested sulfonamides, compounds 21, 22, 23, 35 and 41 exhibited
100% cytotoxic effects with low (< 10 µM) EC50 values on K562 cells. The cytotoxicity of lead compound 22 was investigated
in 24 different cancer cell lines, and it was found to be active against leukemia, melanoma, glioblastoma, and liver,
breast and lung cancer cells, as confirmed by classical biochemical and holographic microscopic analyses.
合成了一组包含30个成员的哌啶环融合芳香磺酰胺库,包括N-芳基磺酰基的1,2,3,4-四氢喹啉、1,2,3,4-四氢异喹啉和2,3,4,9-四氢-1H-吡啶[3,4-b]吲哚。该化合物在HT168黑色素瘤细胞和K562白血病细胞中诱导了氧化应激和谷胱甘肽耗竭,并在微摩尔浓度下表现出细胞毒性效应。在测试的磺酰胺中,化合物21、22、23、35和41在K562细胞上表现出100%的细胞毒性效应,且EC50值较低(< 10 µM)。在24种不同癌细胞系中研究了主要化合物22的细胞毒性,结果发现其对白血病、黑色素瘤、胶质母细胞瘤,以及肝癌、乳腺癌和肺癌细胞均具有活性,这一点通过经典的生化和全息显微镜分析得到了确认。
