  Ligand based design of novel histamine H4 receptor antagonists; fragment optimization and analysis of binding kinetics

  摘要：

  The histamine H-4 receptor is a G protein-coupled receptor that has attracted much interest for its role in inflammatory and immunomodulatory functions. In our search for new H4R ligands, a low affinity isoquinoline fragment was optimized to 7-(furan-2-yl)-4-(piperazin-1-yl)quinazolin-2-amine (VUF11489), as a new H4R antagonist. Analysis of its binding kinetics at the human H4R showed this compound to have a very different dissociative half-life in comparison with reference antagonist JNJ7777120. (C) 2011 Elsevier Ltd.

  This invention relates to an anti-dementia agent which uses a BEC 1 potassium channel inhibitor as the active ingredient. It was proved that the BEC 1 potassium channel inhibitor has an action to improve learning disorder and is useful as a preventive or therapeutic agent for diseases, preferably dementia, in which the BEC 1 potassium channel is considered to be concerned. Illustratively, it was confirmed by an in vivo test that the BEC 1 potassium channel inhibitor has an action to improve learning disorder. Also, it was found that a compound having 2,4,6-triamino-1,3,5-triazine has a BEC 1 potassium channel inhibitory action.
