  A synthetic ditryptophan conjugate that rescues bacteria from mercury toxicity through complexation

  摘要：

  The synthesis of ditryptophan-pyridine conjugates and their binding to mercury ions is described. Conjugate 3 shows an excellent ability to sequester mercury from solution and rescue bacterial growth in a concentration-dependent survival assay. It is proposed that such compounds, composed primarily of bioessential/biodegradable components, could be potentially used as sequestrating agents for the removal of Hg(II) ions in detoxification strategies.

  bis-amide receptors for anion binding that contain carboxylic acid groups vicinal to the amide function. Deprotonation of the carboxylic acids decreases the acidity of amide NHs, switching on the anion binding ability of the deprotonated receptors with selectivity for fluoride complexation. The proposed systems represent a unique example of anionic receptors able to bind anions via H-bonding.

  在这里，我们报告了一个双酰胺阴离子结合受体家族，其中含有对酰胺功能不利的羧酸基团。羧酸的去质子化降低了酰胺NHs的酸度，从而切换了去质子化受体的阴离子结合能力，并具有氟化物络合的选择性。提出的系统代表了能够通过H键与阴离子结合的阴离子受体的独特实例。
