摘要:

合成了一种基于锌配合物检测NO的荧光探针CMD-Zn2+. 以萘并呋喃酰肼和久洛尼定醛为原料, 经缩合反应制备了配体CMD, 再将它与锌离子结合形成探针CMD-Zn2+, 该探针可特异性识别NO. 利用高分辨率质谱(HRMS)和核磁共振氢谱(1H NMR)对CMD的结构进行了表征, 利用荧光光谱和紫外-可见吸收光谱考察了探针CMD-Zn2+对NO的识别性能. 实验结果表明, 在其它竞争离子存在的情况下, 探针CMD-Zn2+可特异性快速识别NO, 响应时间为30 s, 识别NO的检出限为8.23×10‒9 mol/L. 此外, 探针CMD-Zn2+被成功应用于细胞和活鼠的荧光成像研究.

Abstract:

A fluorescent probe CMD-Zn2+ based on zinc complexes was constructed for NO detection, Ligand CMD was prepared by naphthalene and furanide and ligonidaldehyde by condensation reaction. The ligand CMD was combined with zinc ions to form the probe CMD-Zn2+. The probe CMD-Zn2+ could specifically recognize NO. The recognition performance of probe CMD-Zn2+ was examined by fluorescence spectroscopy and UV absorption spectroscopy, and the structure of CMD was characterized by high-resolution mass spectroscopy(HRMS) and nuclear magnetic resonance hydrogen spectroscopy(1H NMR). The experimental results showed that in the presence of other competing ions, the probe CMD-Zn2+ specifically recognized NO, and the detection limit of NO recognition was 8.23×10‒9 mol/L. The probe CMD-Zn2+ has been successfully applied in fluorescence imaging studies in cells and live mice.
