  Methyltrioxorhenium-catalyzed epoxidation of olefins with hydrogen peroxide as an oxidant and pyridine N-oxide ionic liquids as additives

  摘要：

  Four ionic liquids (ILs) with both a pyridine N-oxide moiety and an imidazolium moiety combined by an amide spacer were synthesized through a series of reactions including amidation, peroxidation, quaterization and anion exchange reaction. Their structures were fully characterized by H-1 NMR, FT-IR, UV-vis and HR-MS. The ionic liquids were used respectively as additives in the methyltrioxorhenium (MTO) catalyzed epoxidation of olefins with 30% H2O2 as an oxidant. The catalytic results displayed that the ILs had excellent performances in suppressing epoxide ring-opening reaction, which led to the significant improvement of the selectivity of the MTO-catalyzed epoxidation with low loadings compared to other substances as additives. The coexistence of the pyridine N-oxide and imidazolium moieties in the structures of ILs is necessary in improving the MTO-catalyzed epoxidation reaction. It was also displayed that the improvement degree on the selectivity of epoxidation depended on the type of anion of the ILs, but not the position of the substituent with imidazolium moiety in the ring of pyridine N-oxide. Meanwhile, the results also showed that the introduction of the ILs caused the decrease of the epoxidation rate, but this side effect was small compared to those of other substances used as additives.

• Surface modification of silica nanoparticles: a new strategy for the realization of self-organized fluorescence chemosensors
  作者：Enrico Rampazzo、Elena Brasola、Silvia Marcuz、Fabrizio Mancin、Paolo Tecilla、Umberto Tonellato

  DOI：10.1039/b502052b

  The self-organization of the proper subunits of a fluorescence chemosensor on the surface of silica nanoparticles allows the easy design and realization of new effective sensing systems. Commercially available silica particles (20 nm diameter) were functionalized with triethoxysilane derivatives of selective Cu(II) ligands and fluorescent dyes. Grafting of the sensor components to the particle surface ensures the spatial proximity between the sensor components and, as a consequence, binding of Cu(II) ions by the ligand subunits leads to quenching of the fluorescent units emission. In 9 : 1 DMSO–water solution, the coated silica nanoparticles (CSNs) selectively detect copper ions down to nanomolar concentrations. The operative range of the sensors can be tuned either by switching the ligand units or by modification of the components ratio. Sensors with the desired photophysical properties can be easily prepared by using different fluorescent dyes. Moreover, the organization of the network of sensor components gives rise to cooperative and collective effects: on one hand, the ligand subunits bound to the particle surfaces cooperate to form multivalent binding sites with an increased affinity for the Cu(II) ions; on the other hand, binding of a single metal ion leads to the quenching of several fluorescent groups producing a remarkable signal amplification.

  二氧化硅纳米颗粒表面上荧光化学传感器的适当亚基的自组装使得易于设计和实现新的有效传感系统。商业可获得的二氧化硅颗粒（20nm直径）通过三乙氧基硅烷衍生的选择性Cu(II)配体和荧光染料进行功能化。将传感器组件嫁接到颗粒表面上确保传感器组件之间的空间接近，因此，配体亚基结合Cu(II)离子导致荧光单元的荧光发射熄灭。在9：1 DMSO-水溶液中，涂层的二氧化硅纳米颗粒（CSNs）能够选择性地检测铜离子，检测极限达到纳摩尔浓度。传感器的操作范围可以通过切换配体单元或通过改变组件比例来进行调节。通过使用不同的荧光染料，可以很容易地制备具有所需光物理性质的传感器。此外，传感器组件的网络组织导致协同和集体效应：一方面，连接在颗粒表面上的配体亚基协作形成具有增加的亲和力的多价结合位点用于Cu(II)离子；另一方面，单个金属离子的结合导致几个荧光基团的熄灭，产生显著的信号增强。

  Sialic acid sugars that terminate cell‐surface glycans form the ligands for the sialic acid binding immunoglobulin‐like lectin (Siglec) family, which are immunomodulatory receptors expressed by immune cells. Interactions between sialic acid and Siglecs regulate the immune system, and aberrations contribute to pathologies like autoimmunity and cancer. Sialic acid/Siglec interactions between living cells

  终止细胞表面聚糖的唾液酸糖形成唾液酸结合免疫球蛋白样凝集素（Siglec）家族的配体，后者是免疫细胞表达的免疫调节受体。唾液酸和Siglecs之间的相互作用调节免疫系统，而像差则导致自身免疫和癌症等病理。由于缺乏特定的工具，很难研究活细胞之间的唾液酸/ Siglec相互作用。在这里，我们报告了一种糖工程方法来重塑唾液酸的活细胞及其与Siglecs的结合。使用生物正交化学，产生了具有六十多种不同唾液酸修饰的细胞文库，该文库显示出与不同Siglec家族成员的结合显着增加。合理的设计降低了交叉反应性，并导致发现了三种选择性Siglec-5 / 14配体。此外，携带针对Siglec-3的唾液酸配体的糖工程细胞抑制了Siglec-3的活化+单核细胞通过NF-κB和IRF途径。
