    名称:
    Fluorescent Sensors for Zn2+ Based on a Fluorescein Platform:  Synthesis, Properties and Intracellular Distribution
    摘要:
    Two new fluorescent sensors for Zn2+ that utilize fluorescein as a reporting group, Zinpyr-1 and Zinpyr-2, have been synthesized and characterized. Zinpyr-1 is prepared in one step via a Mannich reaction, and Zinpyr-2 is obtained in a multistep synthesis that utilizes 4 ' ,5 ' -fluorescein dicarboxaldehyde as a key intermediate. Both Zinpyr sensors have excitation and emission wavelengths in the visible range (similar to 500 nm), dissociation constants (K-d1) for Zn2+ of <1 nM, quantum yields approaching unity (Phi = similar to0.9), and cell permeability, making them well-suited for intracellular applications. A 3- to 5-fold fluorescent enhancement is observed under simulated physiological conditions corresponding to the binding of the Zn2+ cation to the sensor, which inhibits a photoinduced electron transfer (PET) quenching pathway. The X-ray crystal structure of a 2:1 Zn2+:Zinpyr-1 complex has also been solved, and is the first structurally characterized example of a complex of fluorescein substituted with metal binding ligands.

  • LABELS, THEIR PRODUCTION PROCESS AND THEIR USES

    Labels are disclosed capable of forming a covalent or non-covalent bond with a target molecule, particularly a biological molecule. The structure of these labels may consist of a dye covalently bound by one or more carbons on its chemical structure to one or more [FUNC] group(s), and optionally one or more [SOL] group(s). The structure of these labels allow selection of dyes from a wide variety of different excitation and emission wavelengths and allow easy functionalization of the dye without appreciably altering its spectral characteristics or its solubility characteristics.
    标签可以与目标分子形成共价或非共价键,特别是生物分子。这些标签的结构可能由染料共价结合到其化学结构上的一个或多个碳上,以及一个或多个[FUNC]基团,和可选地一个或多个[SOL]基团。这些标签的结构允许从各种不同的激发和发射波长中选择染料,并且允许轻松地对染料进行功能化,而不会明显改变其光谱特性或溶解特性。

    The invention provides Zn-chelating compounds that are molecularly engineered to bind to a specific target sequence in a protein of interest. The Zn 2+ 0 ion is far less toxic and promiscuous than nickel and therefore provides an attractive alternative to Ni-based labeling systems. Invention Zn-chelating compounds also do not require oxidizable thiols and therefore can be used in non-reducing environments such as the surface of living cells. In addition, the target sequence is genetically encodable and requires incorporation of only a few amino acids, unlike fusions to fluorescent proteins such as GFP.
    这项发明提供了分子工程设计的Zn螯合化合物,可以结合到感兴趣蛋白质中的特定靶标序列。Zn2+0离子比镍毒性和广泛性要小得多,因此是镍基标记系统的一个有吸引力的替代选择。该发明的Zn螯合化合物也不需要可氧化的硫醇,因此可以在非还原环境中使用,比如生物细胞表面。此外,靶标序列是遗传可编码的,只需要引入少量氨基酸,不像与荧光蛋白(如GFP)融合那样需要。
