The systematic studies of chromone appended novel chemosensors, favored to Mg ion detection, these were analyzed and characterized by different spectroscopic techniques such as NMR, mass spectroscopy, FTIR and optical techniques. The binding demeanor of the ligands was executed with the library of metal ions and shown the good coordination with Mg ion to the ligand's cavity. Both ligands demonstrated good binding behavior with Mg ion. The ligands represented 1: 1 stoichiometry with Mg ions through Job's plot. The low limit of detection of Mg ion was determined as 2.56 × 10 and 1.28 × 10 for L and L respectively. No interference was occurred in Inference study by foreign metal ions that supported the specific detection of Mg ion among the other metal ions. Further, the cytotoxicity assay test of these chromone appended ligands revealed that both ligands and their respective compound with Mg ion shown negligible toxicity with HeLa cancer cell line. Further, due to the fluorescence properties of the ligands, with or without Mg ion was successfully tested in bioimaging experiment of HeLa cancer cell lines and found that ligands with Mg ions represented good imaging with HeLa cancer cell.
系统研究了具有新型化学传感器功能的色酮,有利于镁离子的检测,这些化学传感器通过 NMR、质谱、FTIR 和光学技术等不同的光谱技术进行了分析和表征。配体的结合行为与金属离子文库进行了比较,并显示出与配体腔的良好配位作用。两种配体都表现出与镁离子的良好结合行为。配体与镁离子的配位比通过 Job 图表示为 1:1。镁离子的最低检测限分别为 2.56×10 和 1.28×10 对于 L 和 L。在外国金属离子的推断研究中没有发生干扰,这支持了在其他金属离子中特异性检测镁离子。此外,这些色酮缀合配体的细胞毒性测定试验表明,两种配体及其与镁离子的相应化合物对 HeLa 癌细胞系表现出可忽略的毒性。此外,由于配体的荧光性质,无论是否有镁离子,都成功地在 HeLa 癌细胞系的生物成像实验中进行了测试,并发现与镁离子的配体在 HeLa 癌细胞中具有良好的成像能力。
