  摘要：

  G蛋白偶联受体（GPCR）除通过G蛋白依赖性经典途径外，还能够通过不同的非经典途径（例如β-arrestin）进行下游信号传导。差异激活下游信号传导途径的GPCR配体称为功能选择性或偏向配体。最近公开了一类新型的多巴胺D1受体（D1R）的非儿茶酚G蛋白偏向的激动剂。我们进行了第一个全面的结构-功能选择性关系研究，测量了该支架的四个区域的GS和β-arrestin2募集活动，结果得到了50多个具有不同功能选择性谱的类似物。与起始化合物相比，某些化合物成为β-arrestin2募集的有效全效激动剂，而其他化合物则显示出更高的GS偏倚。具有改变的功能选择性特征的类似物的药代动力学测试表明，血脑屏障渗透性极佳。这项研究为研究D1R的配体偏倚提供了新颖的工具，并为开发下一代有偏向的D1R配体铺平了道路。

• Ortho selectivity in SNAr substitutions of 2,4-dihaloaromatic compounds. Reactions with piperidine

  日期：2010.1

  A broad survey of aromatic compounds with halogens positioned both ortho and para to activating groups was studied in SNAr reactions with piperidine. Regioselectivities varied with the substituent group and the polarity of the solvent. Many activating groups exhibited an overall bias toward ortho-substitution, and this led in nonpolar solvents to very high ortho selectivity. More polar solvents uniformly

  protein-coupled receptors (GPCRs) are capable of downstream signaling through distinct noncanonical pathways such as β-arrestins in addition to the canonical G protein-dependent pathways. GPCR ligands that differentially activate the downstream signaling pathways are termed functionally selective or biased ligands. A class of novel non-catechol G protein-biased agonists of the dopamine D1 receptor (D1R) was
