    Fluorophore Targeting to Cellular Proteins via Enzyme-Mediated Azide Ligation and Strain-Promoted Cycloaddition
    摘要:
    Methods for targeting of small molecules to cellular proteins can allow imaging with fluorophores that are smaller, brighter, and more photostable than fluorescent proteins. Previously, we reported targeting of the blue fluorophore coumarin to cellular proteins fused to a 13-amino acid recognition sequence (LAP), catalyzed by a mutant of the Escherichia coli enzyme lipoic acid ligase (LplA). Here, we extend LplA-based labeling to green- and red-emitting fluorophores by employing a two-step targeting scheme. First, we found that the W37I mutant of LplA catalyzes site-specific ligation of 10-azidodecanoic acid to LAP in cells, in nearly quantitative yield after 30 min. Second, we evaluated a panel of five different cyclooctyne structures and found that fluorophore conjugates to aza-dibenzocyclooctyne (ADIBO) gave the highest and most specific derivatization of azide-conjugated LAP in cells. However, for targeting of hydrophobic fluorophores such as ATTO 647N, the hydrophobicity of ADIBO was detrimental, and superior targeting was achieved by conjugation to the less hydrophobic monofluorinated cyclooctyne (MOFO). Our optimized two-step enzymatic/chemical labeling scheme was used to tag and image a variety of LAP fusion proteins in multiple mammalian cell lines with diverse fluorophores including fluorescein, rhodamine, Alexa Fluor 568, ATTO 647N, and ATTO 655.

    用于异染色质高效染色的罗丹明-Hoechst 位置异构体†
    摘要:
    Hoechst 荧光染料缀合物是活细胞成像中常用的 DNA 染色剂,但其结构和性能之间的关系仍然难以捉摸。这项对羧罗丹明-Hoechst 33258 缀合物的研究表明,染料附着点的微小变化会对最终探针的特性产生巨大影响。所有测试的含 6'-羧基染料的探针均表现出与 DNA 的双模式结合,并在高 DNA 浓度下形成二聚体复合物。含有 5'-羧基染料的探针表现出与 DNA 的单模式结合,从而增加了亮度并降低了细胞毒性。新开发的探针的核染色亮度提高了 10 倍,可以在活细胞和固定细胞中获取质量出色的受激发射损耗 (STED) 纳米图像。因此,我们能够估计活细胞和完整鸡红细胞核孔区域异染色质禁区直径约 155 nm,并定位活 U-2 OS 细胞中相对于异染色质的端粒。采用双色 STED 的高效探针可以实现完整有核红细胞中 DNA 和微管蛋白结构的可视化——在该系统中,高血红蛋白吸光度极大地阻碍了成像。

    The present invention relates to chemical linkers and protecting groups, compounds and compositions containing the chemical linkers or protecting groups, and intermediates and processes that can be used to prepare them. The chemical linkers and protecting groups are based on pyrrolidine and piperidine activating groups, which undergo intramolecular cyclisation upon heating with release of carbon dioxide, thereby releasing the organic compound from a substrate. In particular, those chemical linkers and protecting groups are useful in the solid phase synthesis of oligonucleotides according to the following representative schemes.

    To study the behavior of MDM2p53 inhibitors in a disease‐relevant cellular model, we have developed and validated a set of bioorthogonal probes that can be fluorescently labeled in cells and used in high‐content screening assays. By using automated image analysis with single‐cell resolution, we could visualize the intracellular target binding of compounds by co‐localization and quantify target upregulation

    reduce the enamine N-oxide to induce dissociation and compound release. This reaction can be paired with the corresponding bioorthogonal hydroamination reaction to afford an integrated system of bioorthogonal click and release via an enamine N-oxide linchpin with a minimal footprint. The tandem associative and dissociative reactions are useful for the transient attachment of proteins and small molecules
