  Methylenedioxy flavonoids: Assessment of cytotoxic and anti-cancer potential in human leukemia cells

  摘要：

  A new series of chalcones, flavanones and flavones with methylenedioxy group at the 3',4' position in chalcone, 7,8 position in flavanones and flavones with mono-, di- and trimethoxy groups in the benzaldehyde ring have been assessed for their effect on proliferation, cytotoxic potential and apoptosis in human leukemia cells. Among the tested compounds, the chalcone series showed the best activity and chalcone 3 (mono methoxy group at the ortho position in A-ring) showed a significant effect on down-regulation of cancer cell proliferation and viability in three different leukemia cell lines (K562, Jurkat, U937). The executioner caspase cleavage analyses indicated that the cytotoxic effect mediated by chalcone 3 is due to induction of apoptotic cell death. Interestingly, the cytotoxic effect was cell type-specific and targeted preferentially cancer cells as peripheral blood mononuclear cells (PBMCs) from healthy donors were less affected by the treatment compared to K562, Jurkat and U937 leukemia cells. Altogether our results indicate a potential drug candidate with interesting differential toxicity obeying Lipinski's rule of five.

  摘要：

  理由数种被单，二和三甲氧基取代的亚甲二氧基查耳酮，黄烷酮和黄酮已用于治疗增生性疾病，例如癌症和炎性疾病。这些类黄酮在生物学中的应用需要一种分析方法，以确保药物代谢后对其结构的详细了解。方法使用Q-TOF 2仪器获得电喷雾电离质谱（ESI-MS）和串联质谱（ESI-MS / MS）光谱。使用标准的分离和激发程序（激活q值为0.25，激活时间为30 ms），通过在LXQ线性离子阱质谱仪中获得的CID-MS（2-3）谱图分析了碎片模式及其途径。ESI-MS和ESI-MS（n）条件：喷雾电压5 kV，氮气8.00鞘气流速（任意），加热的毛细管温度275°C，毛细管电压10.99 V; 镜筒透镜电压为75.01V。结果查耳酮的ESI-MS / MS谱图与其相应的异构黄烷酮具有（0，α）A（+）/（1,3）A（+）和（0,1' ）B（+）/（1,4）B（+）裂解。其他常见的损失包括（•）CH3，H2O

  tandem mass (ESI-MS/MS) spectra were acquired using a Q-TOF 2 instrument. Fragmentation patterns and their pathways were analyzed by CID-MS(2-3) spectra acquired in a LXQ linear ion trap mass spectrometer using standard isolation and excitation procedures (activation q value of 0.25, activation time of 30 ms). ESI-MS and ESI-MS(n) conditions: spray voltage 5 kV, nitrogen 8.00 sheath gas flow rate (arb)
