  suppress its induced effect. The moiety resembling the tyrosyl side chain of the translation inhibitor puromycin was synthetically modified to the photosensitive ortho-nitrophenylalanine that cyclizes upon near UV-irradiation to an inactive puromycin cinnoline derivative. Additionally, the modified puromycin analog was protected by the thio-coumarylmethyl group as the second PPG. This TPOM strategy allows

  光可裂解保护基团 (PPG) 在众多研究中发挥着关键作用。它们能够控制释放小效应分子以诱导生化功能。近年来，附着在各种效应分子上的 PPG 数量迅速增长，满足了对新应用的高需求。然而，迄今为止，携带 PPG 的分子被设计为仅在一个方向上激活功能，即效应分子的释放。在此，我们提出了一种新方法双 PPG 单分子 (TPOM)，该方法利用两个光保护基团的正交光解首先释放效应分子，然后对其进行修饰以抑制其诱导效应。类似于翻译抑制剂嘌呤霉素酪氨酰侧链的部分被合成修饰为光敏邻硝基苯丙氨酸在近紫外线照射下环化为无活性的嘌呤霉素肉啉衍生物。此外，修饰的嘌呤霉素类似物受到硫代保护-香豆基甲基作为第二个PPG。这种 TPOM 策略允许初始波长选择性激活，然后是第二次光诱导失活。两种光解过程都在紫外/可见光和红外区域进行了光谱研究。结合量子化学计算和时间分辨核磁共振光谱，表征了照射后激活和失活步骤的光产物。我们

  The light‐triggered, programmable rupture of cell‐sized vesicles is described, with particular emphasis on self‐assembled polymersome capsules. The mechanism involves a hypotonic osmotic imbalance created by the accumulation of photogenerated species inside the lumen, which cannot be compensated owing to the low water permeability of the membrane. This simple and versatile mechanism can be adapted

  描述了光触发的可编程的细胞大小囊泡破裂，特别强调了自组装的多聚体胶囊。该机制涉及由内腔内光生物质的积累所引起的低渗渗透失衡，由于膜的低透水性而无法补偿。这种简单而通用的机制可以适应大量的水溶性分子，这些分子既可以生成活性氧，也可以进行光裂解。最终，在多隔室的细胞样系统中，证明了以高特异性和时间精度选择性地破裂多聚体并因此递送小的包囊小泡（多聚体和脂质体）的可能性。
• Development of novel water-soluble photocleavable protective group and its application for design of photoresponsive paclitaxel prodrugs

  A novel coumarin-based highly water-soluble photocleavable protective group was designed and synthesized, and then this photosensitive protecting group was used to design paclitaxel prodrugs. These novel paclitaxel conjugates demonstrated excellent water solubility, over 100 mg mL(-1). Thus, the use of a detergent in the formulation can be omitted completely, even at high doses. Phototaxel 11 released the parent drug, paclitaxel, quickly and efficiently by minimal tissue-damaging 365 nm UV light irradiation at low power, while laser activation at 355 nm led to extensive decomposition of the prodrug. The carbamate-type prodrug, phototaxel 11, was stable in the dark prior to activation, whereas carbonate-type phototaxel 9 demonstrated poor stability under aqueous conditions. For such prodrugs, tumor-tissue targeting after administration could be achieved by selective light delivery, similar to that used in photodynamic therapy. In addition, newly designed coumarin derivative 8 can be applied in organic chemistry as a photosensitive protective group and for the design of caged compounds. (C) 2008 Elsevier Ltd.
