For detecting reduced glutathione (GSH) with a 19F NMR spectroscopy with time-specificity, we developed the probes based on gold nanoparticles modified with the fluorinated groups via the thermally-cleavable linkers. Before the heating treatment with the probe, the maleimide moiety as a binding site with GSH in the probe is inactivated by cycloaddition of furan. At this silent state, the magnitude
为了用具有时间特异性的19 F NMR光谱检测还原型谷胱甘肽(GSH),我们开发了基于通过热裂解连接基团被氟化基团修饰的金纳米颗粒的探针。在用探针进行加热处理之前,通过呋喃的环加成使马来酰亚胺部分作为与探针中与GSH的结合位点失活。在该静默状态下,来自氟化基团的19 F NMR信号的幅度被抑制。通过加热以激活探针,通过逆狄尔斯-阿尔德反应生成了马来酰亚胺部分,并观察到19 F NMR信号。从这一刻起,GSH通过添加到马来酰亚胺部分的Michael分子开始与探针反应,从而观察到19 F NMR谱。最后,由19 F NMR信号强度的增加来确定GSH的量。
