  摘要：

  白藜芦醇是一种具有多种有趣生物活性的天然多酚。然而，它在体内的药理利用受到其在肠道和肝脏（最重要的是）通过II相共轭代谢迅速消除的阻碍。一种绕过这一问题的方法依赖于前药。我们在这里报告了白藜芦醇前药的合成、表征、水解和体内药代动力学行为，其中OH基团参与了N-单取代氨基甲酸酯酯键。作为载体，使用了一系列定义链长（n=3、4、6）的甲氧基聚乙二醇（m-OEG）（CH3–[OCH2CH2]n–）。这些有望像较长的聚乙二醇（PEG）链一样，调节所得到的衍生物的化学物理性质，同时保留相对较低的分子量，从而具有良好的药物负载能力。对大鼠进行胃内给药，结果表明，血液中出现了前药及其部分水解产物，证实了在吸收过程中避免了首次通过代谢的保护。

  摘要：

  合成了新型的蒽荧光探针-宿主1–4，通过酯或醚键连接到冠醚或聚醚侧臂。向宿主溶液中添加碱土金属阳离子会引起独特的荧光强度变化。具体而言，通过酯键连接的宿主（化合物1和3）会导致荧光淬灭，而通过醚键连接的宿主（化合物2和4）则会导致荧光增强。具有冠醚侧臂的宿主（化合物2）对钙阳离子的识别能力强于对钡阳离子的识别能力；相反，具有聚醚侧臂的宿主（化合物4）则更倾向于识别钡阳离子而非钙阳离子。

  artificial β‐barrel proteins at will. Here, we describe a rational approach to construct β‐barrel protein mimics from the self‐assembly of peptide‐based building blocks. With this approach, the direction of the self‐assembly process toward the formation of water‐soluble β‐barrel nanorings or water‐insoluble transmembrane β‐barrel pores could be controlled by the simple but versatile molecular manipulation

  呈环状的β-桶蛋白在许多类型的水溶性酶和水不溶性跨膜成孔蛋白中很常见。由于β-桶形蛋白质在细胞中具有多种功能，因此，如果我们能够随意控制人工β-桶形蛋白质的极性，这将是开发人工蛋白质的重要​​一步。在这里，我们描述了一种从基于肽的构件的自组装构建β-桶状蛋白模拟物的合理方法。通过这种方法，可以通过对超分子构件的简单而通用的分子操作来控制自组装过程向水溶性β-桶纳米环或水不溶性跨膜β-桶孔形成的方向。

  Diarylethene derivatives with hexaethylene glycol side chains were synthesized and their self-assembling and photochromic reactivity were investigated. The diarylethenes showed photochromism in organic solvents and even in water. The aqueous solution of the compounds turned turbid quickly upon heating. The clouding behavior was investigated using 1H NMR spectroscopy, dynamic light scattering, and absorption
