  基于四氢[5]螺旋烯的纳米粒子，用于依赖结构的细胞荧光成像

  摘要：

  设计并合成了四种具有四氢[5]螺旋结构的新型荧光染料，其特征是具有三基色发射色（蓝绿色红色），并通过NMR，MS和单晶X射线晶体学对其结构进行了表征。然后通过再沉淀法制备了基于荧光染料的有机纳米粒子，并对其光物理性质进行了研究。这些纳米粒子保留了有机染料的强发射性，并且还可以通过简单地调整三基色染料的比例来制备多色纳米粒子。这些有机纳米颗粒显示出低细胞毒性，良好的光稳定性和高量子产率。此外，纳米颗粒也可以应用于细胞荧光成像中。尤其，有趣的是，对于HeLa细胞，这些纳米颗粒从膜到细胞质的染色区域显示出明显的结构依赖性。该策略通过分子设计为活细胞的特定位置成像提供了荧光探针的新视角。

  investigated. These nanoparticles retain the strong emissions of the organic dyes, and multicolor nanoparticles were also prepared by simply tuning the ratios of the three‐primary colors dyes. These organic nanoparticles exhibit low cytotoxicity, good photostability, and high quantum yields. Moreover, the nanoparticles can also be applied in the cell fluorescence imaging. Especially, it is interestingly found

  A new fluorescent chemosensor based on a helical imide as fluorophore and a cyclen moiety as ionophore was synthesized, which not only showed enhanced fluorescent responses in the presence of Zn2+, Cd2+, and Hg2+ but also could simultaneously and selectively distinguish the three cations in a simulated physiological condition with the help of cysteine as an auxiliary reagent.

  In this work, we have designed and synthesized a dinitrobenzene-sulfonate tetrahydro[5]helicene (H-DNP) as an effective fluorescent probe for detection of hydrogen sulfide (H2S). Upon the addition of H2S, a significant fluorescence enhancement (75-fold) at 495 nm can be observed with a distinct color change from colorless to yellow. Additionally, H-DNP shows low background spectroscopic signal, large Stokes Shift up to similar to 140 nm, good sensitivity, rapid response time less than 2 min, low detection limit (48 nM) and high selectivity toward common bio-thiols (Cysteine, Homocysteine and Glutathione). Compared with the previous dinitrophenoxy tetrahydro[5]helicene, this probe has shorter response time and lower detection limit. Most importantly, this probe H-DNP has low toxicity to cells and excellent cell permeability, which can be applied to visualize H2S in living cells. (C) 2019 Elsevier B.V. All rights reserved.
