荧光染料,如罗丹明,被广泛用于分析活性和成像其他看不见的分子的位置。硅罗丹明,其中罗丹明的桥氧被二甲基硅基取代,越来越多地成为生物应用的首选染料支架,因为荧光被转移到近红外,同时保持高亮度。尽管人们对硅-罗丹明有浓厚的兴趣,但还没有人探索这些染料中硅的官能化范围,这是传统罗丹明中不存在的一个潜在的修饰部位。在这里,我们报告了一系列硅基修饰,使染料变得更明亮,进一步红移,调制荧光的新方法,并引入了用于染料附着的手柄,包括用于核DNA、SNAP-Tag和HaloTag标记的荧光标记剂。因此,对桥联硅的改性对改进和扩大所有硅染料的应用具有广泛的用途。硅-罗丹明染料的桥联硅原子的功能化允许调整染料性能、传感器的附着以及添加对构建活细胞成像探针有用的生物分子靶向配体。
Fluorescent dyes such as rhodamines are widely used to assay the activity and image the location of otherwise invisible molecules. Si-rhodamines, in which the bridging oxygen of rhodamines is replaced with a dimethyl silyl group, are increasingly the dye scaffold of choice for biological applications, as fluorescence is shifted into the near-infrared while maintaining high brightness. Despite intense interest in Si-rhodamines, there has been no exploration of the scope of silicon functionalization in these dyes, a potential site of modification that does not exist in conventional rhodamines. Here we report a broad range of silyl modifications that enable brighter dyes, further red-shifting, new ways to modulate fluorescence, and the introduction of handles for dye attachment, including fluorogenic labeling agents for nuclear DNA, SNAP-tag and HaloTag labeling. Modifications to the bridging silicon are therefore of broad utility to improve and expand the applications of all Si-dyes. Functionalization of the bridging silicon atom of Si-rhodamine dyes allows tuning of dye performance, the attachment of sensors, and the addition of biomolecular targeting ligands useful for the construction of live cell imaging probes.
