  Chemical Subtleties in Small-Molecule Modulation of Peptide Receptor Function: The Case of CXCR3 Biaryl-Type Ligands

  摘要：

  The G protein-coupled chemokine receptor CXCR3 plays a role in numerous inflammatory events. The endogenous ligands for the chemokine receptors are peptides, but in this study we disclose small-molecule ligands that are able to activate CXCR3. A class of biaryl-type compounds that is assembled by convenient synthetic routes is described as a new class of CXCR3 agonists. Intriguingly, structure-activity relationship and structure-function relationship studies reveal that subtle chemical modifications on the outer aryl ring (e.g., either the size or position of a halogen atom) result in a full spectrum of agonist efficacies on CXCR3. Quantum mechanics calculations and nuclear Overhauser effect spectroscopy NMR studies suggest that the biaryl dihedral angle and the electronic nature of ortho-substituents play an important role in determining agonist efficacies. Compounds 38 (VUF11222) and 39 (VUF11418) are the first reported nonpeptidomimetic agonists on CXCR3, rendering them highly useful chemical tools for detailed assessment of CXCR3 activation as well as for studying downstream CXCR3 signaling.

  聚（邻氨基苯硫酚）稳定的Pd纳米颗粒作为铃木交叉偶联反应的有效多相催化剂

  摘要：

  聚（Ô -aminothiophenol）（PATP） -稳定的钯纳米粒子与钯纳米粒子包埋在聚合物基质已通过混合通过一个浅显一步法途径获得ö -aminothiophenol单体和Pd（NO 3）2在酸性水溶液中，而不其他模板或表面活性剂。邻氨基苯硫酚与Pd（NO 3）2的氧化还原反应导致同时形成PATP聚合物和Pd纳米颗粒。通过TEM，FTIR，XRD，ICP-MS和XPS对PATP稳定的Pd纳米颗粒进行了表征。催化结果表明，PATP稳定的Pd纳米颗粒是铃木交叉偶联反应的高度稳定和活性催化剂，其中芳基硼酸和带有多种取代基的芳基卤化物可以实现高收率。

The PATP-stabilized Pd nanoparticles have been characterized by TEM, FTIR, XRD, ICP-MS and XPS. Catalytic results showed that PATP-stabilized Pd nanoparticles were highly stable and active catalysts for Suzuki cross-coupling reactions, where high yields could
