    荧光应变促进的炔烃-重氮环加成反应
    摘要:
    荧光反应,其中非荧光或弱荧光试剂产生高荧光产物,对于生物缀合和材料科学领域中的多种化合物的检测非常有吸引力。在本文中,我们报道了在无催化剂的条件下,与叠氮化物,硝酮,腈氧化物以及单取代和二取代的重氮衍生物一起,用环丙烯酮部分(F1-DIBO)改性的二苯并环辛炔衍生物可以进行快速的应变促进的环加成反应。尽管与腈氧化物,硝酮和二取代的重氮化合物反应生成的环加合物的量子产率较低,但单取代的重氮试剂可产生1 H吡唑衍生物比Fl-DIBO的荧光增强约160倍,亮度增加超过10000倍。从量子化学计算中得出结论,可能是由于存在能量较低的(n,π*)状态,因此与双取代的重氮衍生物反应形成的3 H-吡唑类化合物发生了荧光猝灭。荧光探针Fl-DIBO已成功用于标记重氮标记的蛋白质,而没有可检测到的背景信号。重氮衍生物正在成为生物分子标记的有吸引力的报道者,本文介绍的研究表明,Fl-DIBO可用于可视化此类生物分子,而无需进行探针冲洗。

    A Fluorogenic Probe for the Catalyst-Free Detection of Azide-Tagged Molecules
    摘要:
    Fluorogenic reactions in which non- or weakly fluorescent reagents produce highly fluorescent products can be exploited to detect a broad range of compounds including biomolecules and materials. We describe a modified dibenzocyclooctine that under catalyst-free conditions undergoes fast strain promoted cycloadditions with azides to yield strongly fluorescent triazoles. The Cycloaddition products are more than 1000-fold brighter compared to the Starting cyclooctyne, exhibit large Stokes shift,. and can be excited above 350 nm, which is required for many applications. Quantum mechanical: calculations indicate that the fluorescence increase upon triazole formation is due to large differences in oscillator strengths of the S-0 <-> S-1 transitions in the planar C-2v-symmetric starting material compared to the symmetry broken and nonplanar.cycloaddition products. The new fluorogenic probe was successfully employed for labeling of proteins modified by an azide moiety.

    Bioorthogonal fluorescent turn-on reactions are attractive for the sensitive real-time detection of a variety of phenomena including bioconjugation, chemical reactivity, and material assembly. Herein we describe the use of 3,4-disubstituted sydnones, a singular class of mesoionic dipoles, for highly fluorescent turn-on copper-free click cycloadditions with the fluorogenic dibenzocyclooctyne Fl-DIBO
    生物正交荧光开启反应对于灵敏的实时检测包括生物共轭,化学反应性和材料组装在内的多种现象具有吸引力。在本文中,我们描述了使用3,4-二取代的sydnones(一类中性离子偶极子)与发荧光的二苯并环辛炔Fl-DIBO进行高荧光的无铜点击环加成。与时间依赖性密度泛函理论计算相一致,发现吡唑环加合物具有高荧光性,并具有令人信服的光物理特性,包括出色的荧光增强作用(高达240倍),高量子产率(超过45%)和大的斯托克斯位移(超过100 nm)。此外,4-氯sydnones与Fl-DIBO的良好稳定性和反应性使我们能够将其用作化学报告剂,用于复杂细胞提取物中的修饰蛋白的具有挑战性的检测,并且在免洗条件下具有出色的特异性。这种新颖的荧光系统极大地扩展了我们的化学生物学工具箱,应在无数的应用中受益。

    Herein we describe the synthesis of various simple N-alkyl thalidomide derivatives in order to determine their fluorescence excitation and emission profile. Following this, a series of more complex fragments were attached through a Huisgen 1,3-dipolar cycloaddition providing a more diverse fluorescence profile. A thalidomide azide derivative was also found to be particularly reactive in a copper-free

    Two novel cell-permeable and bacteria-compatible ‘turn-on’ fluorescent probes, designed to be compatible in a multi-dye system and to fluoresce in the blue region exhibiting emission maxima of 440–490 nm, were synthesized. The profluorescent nitroxide probe (11) was developed to visualize and quantify free radical and redox processes, and the Cu(II)-complexed coumarin-based probe (16a) was developed
