Abstract

In this study pillar[5]arene (P5) and a quinoline-functionalized pillar[5]arene (P5-6Q) which is used for detecting radioactive element, gas adsorption and toxic ions were synthesized. These materials were characterized by Nuclear Magnetic Resonance (NMR), Fourier Transform Infrared (FTIR), elemental analysis, melting point, Mass Spectroscopy, Scanning Electron Microscopy (SEM) and Zeta Potential. The cytotoxic and genotoxic potential of P5 and P5-6Q at distinct concentrations of 12.5, 25, 50, and 100 μg/mL were also investigated by Allium ana-telophase and comet assays on Allium cepa roots and Drosophila melanogaster haemocytes. P5 and P5-6Q showed dose dependent cytotoxic effect by decreasing mitotic index (MI) and genotoxic effect by increasing chromosomal aberrations (CAs such as disturbed anaphase-telophase, polyploidy, stickiness, chromosome laggards and bridges) and DNA damage at the exposed concentrations. These changes in P5-6Q were lower than P5. Further research is necessary to clarify the cytotoxic and genotoxic action mechanisms of P5 and P5-6Q at molecular levels.

摘要

在这项研究中,我们合成了一种柱状芳烃(P5)和一种用于检测放射性元素、气体吸附和有毒离子的喹啉功能化柱状芳烃(P5-6Q)。这些材料的特性通过核磁共振(NMR)、傅里叶变换红外(FTIR)、元素分析、熔点、质谱、扫描电子显微镜(SEM)和 Zeta 电位进行了表征。通过对洋葱根尖和黑腹果蝇血细胞进行 Allium ana-telophase 和彗星试验,研究了 P5 和 P5-6Q 在不同浓度(12.5、25、50 和 100μg/mL)下的细胞毒性和遗传毒性。P5 和 P5-6Q 通过降低有丝分裂指数(MI)表现出剂量依赖性的细胞毒性作用,通过增加染色体畸变(如后期-末期紊乱、多倍体、粘性、染色体滞后和桥)和暴露浓度下的 DNA 损伤表现出遗传毒性作用。P5-6Q 的这些变化低于 P5。需要进一步的研究来阐明 P5 和 P5-6Q 在分子水平上的细胞毒性和遗传毒性作用机制。
