  Photoacoustic Probes for Ratiometric Imaging of Copper(II)

  摘要：

  Photoacoustic tomography has emerged as a promising alternative to MRI and X-ray scans in the clinical setting due to its ability to afford high-resolution images at depths in the cm range. However, its utility has not been established in the basic research arena owing to a lack of analyte-specific photoacoustic probes. To this end, we have developed acoustogenic probes for copper(II)-1 and, -2 (APC-1 and APC-2, a water-soluble congener) for the chemoselective visualization of Cu(II), a metal ion which plays a crucial role in chronic neurological disorders such as Alzheimer's disease. To detect Cu(II), we have equipped both APCs with a 2-picolinic ester sensing module that is readily hydrolyzed in the presence of Cu(II) but not :by other divalent metal ions. Additionally, we designed APC-1 and APC-2 explicitly for ratiometric photoacoustic imaging by using an aza-BODIPY dye scaffold exhibiting two spectrally resolved NIR absorbance bands which correspond to the 2-picolinic ester capped and uncapped phenoxide forms. The normalized ratiometric turn-on responses for APC-1 and APC-2 were 89- and: 101-fold, respectively.

  日期：2014.2

  The hydration of aromatic terminal alkynes performed in acetic acid in the presence of catalytic hydrate ironIII sulfate, Fe2(SO4)3·nH2O (4–9 mol %), yields the derived aryl methyl ketones with good to excellent yields. Under comparable conditions (18 mol %, 95 °C, 24 h), bifunctional substrates were transformed into the monoacetyl or the diacetyl derivatives, depending on the structure of the aromatic

  在催化水合硫酸铁III铁，Fe 2（SO 4）3 · n H 2的存在下，在乙酸中进行芳族末端炔的水合反应O（4–9 mol％），可生成衍生的芳基甲基酮，收率好至极好。在可比较的条件下（18 mol％，95°C，24小时），根据芳族二炔的结构，将双功能底物转化为单乙酰基或二乙酰基衍生物。该反应与具有不同性质和环位置的芳基取代基相容，包括羟基，羰基和累积的烃。非亲核硫酸根阴离子的柔软特性可以使三键在布朗斯台德酸性介质中朝形成碳氧键的方向活化。所提出的方案基于容易获得且无毒的材料，在溶剂或金属催化剂中均不存在氯原子。

  differentiation of the SC4 binding of the two switchable species (40 M–1 for the trans-chalcone versus 3.5 × 104 M–1 for the flavylium cation) enables the pH-gated photocontrol of the complexation process. These responsive properties were explored to demonstrate the competitive and selective release of biologically relevant guests from their supramolecular complexes with p-sulfonatocalix[4]arene (SC4), following

  This paper describes the synthesis and biological evaluation of fluoro-pegylated (FPEG) chalcones for the imaging of β-amyloid (Aβ) plaques in patients with Alzheimer’s disease (AD). FPEG chalcone derivatives were prepared by the aldol condensation reaction. In binding experiments conducted in vitro using Aβ(1−42) aggregates, the FPEG chalcone derivatives having a dimethylamino group showed higher
