  Discovery of G Protein-Biased D2 Dopamine Receptor Partial Agonists

  摘要：

  Biased ligands (also known as functionally selective ligands) of G protein-coupled receptors are valuable tools for dissecting the roles of G protein-dependent and independent signaling pathways in health and disease. Biased ligands have also been increasingly pursued by the biomedical community as promising therapeutics with improved efficacy and reduced side effects compared with unbiased ligands. We previously discovered first-in-class,beta-arrestin-biased agonists of dopamine D2 receptor (D2R) by extensively exploring multiple regions of aripiprazole, a balanced D2R agonist. In our continuing efforts to identify biased agonists of D2R, we unexpectedly discovered a G protein-biased agonist of D2R, compound 1, which is the first G protein-biased D2R agonist from the aripiprazole scaffold. We designed and synthesized novel analogues to explore two regions of 1 and conducted structure functional selectivity relationship (SFSR) studies. Here we report the discovery of 1, findings from our SFSR studies, and characterization of novel G protein-biased D2R agonists.

• Palladium-catalyzed monoamination of dihalogenated benzenes
  作者：Simon Birksø Larsen、Benny Bang-Andersen、Tommy Nørskov Johansen、Morten Jørgensen

  DOI：10.1016/j.tet.2008.01.070

  日期：2008.3

  The palladium-catalyzed monoamination of symmetric dibromobenzenes can be performed using a catalyst based on Pd(2)dba(3) and BINAP in the presence of NaO(t-Bu). The analogous transformation of non-symmetric bromoiodobenzenes is most effectively performed with Xantphos as the ligand, while reactions with BINAP were non-selective. These transformations can be scaled uneventfully to >10 g quantities. They do not require drybox or Schlenk techniques, and all reagents are weighed out in air. The resulting monobromoanilines are versatile intermediates for further synthetic transformations. (C) 2008 Elsevier Ltd. All rights reserved.
