  Fluorescence and mass spectrometry studies of the interaction between naproxen and synthetic pseudopeptidic models in organic media

  摘要：

  Time-resolved/steady-state fluorescence and mass spectrometry measurements have shown the preferential binding of a non-steroidal anti-inflammatory drug (NSAID) like naproxen 4 to a synthetic pseudopeptidic receptor built using Phe (9), i.e., bearing an aromatic ring, compared to another model synthesized using Lys (8), i.e., lacking such aromatic ring but with a basic binding site. The quenching of the emission of naproxen by models 8 and 9 has been measured in solvents of different nature and analyzed by means of the Stern-Volmer methodology. In non-polar solvent (dichloromethane) the fluorescence of 4 is quenched to a higher extent by 8 than by 9 but in polar medium (methanol) the opposite occurs. The result in methanol is compatible with the existence of pi-pi stacking interactions between the aromatic rings of naproxen and the aromatic ring of 9. In order to proof this model, mass spectrometry measurements have confirmed the higher stability of the complex formed by 4 and 9 over the related one formed with 8. The observed phenomenon could help to understand the importance of aromaticity in the interactions between NSAIDs and more complex biological macromolecules like misfolded proteins, involved in the development of Alzheimer's disease and other neuropathologies.

  对称仲烷二胺的有效单酰化和不对称二酰化烷二胺的合成。一种新的基于 L-脯氨酸的有机催化剂

  摘要：

  通过使用 PyBOP-HOBt 作为偶联剂，在室温下，在 DIEA 的存在下，开发了一种简单的程序，用于将几种未保护的链烷二胺与羧酸进行单酰化。伯链烷二胺的产率适中，直链或环状仲胺的产率从好到极好。为了说明这些单酰化产物的效用，合成了六种不对称的二酰化链烷二胺。此外，这些化合物之一被评估为不对称羟醛反应中的有机催化剂。
