imaging applications. These new probes display exquisite reactivity towards strain promoted cycloaddition reactions with cycloalkynes allowing fast, efficient and selective labeling in biological media. Styryl-pyridinium sydnone probes were found particularly interesting for click reactions to proceed selectively inside cells.
我们报告合成和使用基于sydnone的profluorphores作为成像应用程序的工具。这些新探针显示出对应变促进的环炔加环加成反应的出色反应性,可在
生物介质中进行快速,高效和选择性标记。人们发现,对于在细胞内选择性进行的点击反应,
苯乙烯基-
吡啶基sydnone探针特别有趣。
