  Salicyaldehyde-based fluorescent sensors with high sensitivity for amino acids

  摘要：

  Structurally simple salicylaldehyde-based fluorescent sensors for amino acids have been obtained by one-step or two-step synthesis. These sensors show significant fluorescence enhancement in the presence of many amino acids at concentrations as low as 10(-5) mol/L. The reversible reaction of the aldehydes with amino acids to form imines in aqueous solution is proposed to account for the observed fluorescence enhancement. (C) 2011 Xi Huai Qiang.

  The α,5-Dicarboxy-2-nitrobenzyl Caging Group, a Tool for Biophysical Applications with Improved Hydrophilicity: Synthesis, Photochemical Properties and Biological Characterization

  摘要：

  AbstractEarlier we reported on the synthesis of α,4‐dicarboxy‐2‐nitrobenyzl caged compounds (Schaper, K. et al. [2002] Eur. J. Org. Chem., 1037–1046). These compounds have the advantage of an increased hydrophilicity compared with the well‐established α‐carboxy‐2‐nitrobenzyl caged compounds; however, the release of the active compound becomes slower due to the introduction of the additional carboxy group. Based upon theoretical calculations we predicted that the release would become faster when the additional carboxy group is moved to the 5‐position. Here we describe the synthesis and the photochemical and biological characterization of an α,5‐dicarboxy‐2‐nitrobenyzl caged compound. The high hydrophilicity of the new caging group is maintained due to the fact that the additional carboxy moiety is preserved, while the release of the active species from the new derivative is even faster than for the reference, an α‐CNB caged compound.
