Materials containing a high density of NO donors or primary amines exhibited the greatest ability to eradicate P. aeruginosa. Of the materials prepared, only the primary amine-terminated heptasubstituted CD derivatives exhibited toxicity against mammalian L929 mouse fibroblast cells.

NTP is then released from the complex in the intracellular milieu and accumulates in nuclei and nucleoli in high concentration. The transport of NTPs proceeds rapidly (seconds to minutes) and selectively even in the presence of other organic anions. We demonstrate
    化学修饰的三磷酸核苷(NTPs)在化学生物学和药物化学中被广泛用作非天然代谢产物。由于阴离子NTP不会渗透到细胞膜上,因此它们相应的中性前体被用于基于细胞的测定中。这些前体在酶促转化后成为活性代谢产物,通常进行不充分。在这里,我们证明了具有代谢活性的NTP可以通过设计的合成三磷酸核苷转运蛋白(SNTT)的作用直接转运到真核细胞和细菌中。转运蛋白由与三磷酸根阴离子形成非共价复合物的受体和使复合物在质膜上移位的细胞穿透剂组成。然后,NTP从细胞内环境中的复合物中释放出来,并以高浓度积聚在细胞核和核仁中。NTP的运输迅速(数秒至数分钟),并且即使在存在其他有机阴离子的情况下也选择性地进行。我们证明,这种将荧光标记的NTPs运入细胞的操作简单有效的方法可用于活细胞DNA的代谢标记。

  • pH-Operated Nanopistons on the Surfaces of Mesoporous Silica Nanoparticles

    日期:2010.9.22
    The development of drug delivery systems for the targeted and on-demand release of pharmaceutical products has risen rapidly to become a contemporary challenge in the field of nanobiotechnology. Biocompatible mechanized phosphonate-clothed silica nanoparticles have been designed and fabricated in which the supramolecular machinery, which covers the surfaces of the nanoparticles, behaves like nanopistons, releasing encapsulated guest molecules in a controlled fashion under acidic conditions. The mechanized nanoparticles consist of a monolayer of beta-cyclodextrin (beta-CD) rings positioned selectively around the orifices of the nanopores of the mesoporous nanoparticles. A rhodamine B/benzidine conjugate was prepared for use as the nanopistons for movement in and out of the cylindrical cavities provided by the beta-CD rings on the surfaces of the nanoparticles. Luminescence experiments indicated that the mechanized nanoparticles were able to store small cargo molecules (e.g., 2,6-naphthalenedisulfonic acid disodium) within their nanopores at neutral pH and then release them by passage through the cavities of the beta-CD rings as soon as the pH was lowered to similar to 5. In further investigations, the phosphonate-covered silica nanoparticles were functionalized selectively with the beta-CD rings, but on this occasion, the seven linkers attaching the rings to the orifices surrounding the nanopores contained cleavable imine double bonds. The beta-CD rings on the surface of the nanoparticles served as gates for the storage of large cargo molecules (e.g., rhodamine B) inside the nanopores of the nanoparticles under neutral conditions. Since imine bonds can be hydrolyzed under acidic conditions, the beta-CD rings could be severed from the surface of the nanoparticles when the pH was decreased to 6, releasing the large cargo molecules. The results described here present a significant step toward the development of pH-responsive nanoparticle-based dual drug delivery vehicles that are potentially capable of being interfaced with biological systems.
