荧光分子是进行高级生物化学和生物学实验的重要工具。然而,现存的荧光探针的收集是不完整的,留下了未利用的电磁波谱区域。在这里,我们合成绿色激发的荧光和荧光类似物的经典荧光素和罗丹明110荧光团取代的氧杂蒽与季碳。这些蒽基“碳荧光素”和“carborhodamine 110”荧光团表现出优异的荧光特性,可以与酶和光不稳定基团掩蔽,以制备高对比度的荧光分子,用于活细胞成像实验和超分辨率显微镜。我们对这些红移染料支架的不同方法将使许多具有高生物实用性的新型荧光探针的制备成为可能。
Fluorogenic molecules are important tools for advanced biochemical and biological experiments. The extant collection of fluorogenic probes is incomplete, however, leaving regions of the electromagnetic spectrum unutilized. Here, we synthesize green-excited fluorescent and fluorogenic analogues of the classic fluorescein and rhodamine 110 fluorophores by replacement of the xanthene oxygen with a quaternary carbon. These anthracenyl “carbofluorescein” and “carborhodamine 110” fluorophores exhibit excellent fluorescent properties and can be masked with enzyme- and photolabile groups to prepare high-contrast fluorogenic molecules useful for live cell imaging experiments and super-resolution microscopy. Our divergent approach to these red-shifted dye scaffolds will enable the preparation of numerous novel fluorogenic probes with high biological utility.
