  Positive and Negative Modulation of Group I Metabotropic Glutamate Receptors

  摘要：

  A discriminating pharmacophore model for noncompetitive metabotropic glutamate receptor antagonists of subtype 1 (mGluR1) was developed that facilitated the discovery of moderately active mGluR1 antagonists. One scaffold was selected for the design of several focused libraries where different substitution patterns were introduced. This approach facilitated the discovery of potent mGluR1 antagonists, as well as positive and negative mGluR5 modulators, because both receptor subtypes share similar binding pockets. For mGluR1 antagonists, a homology model of the mGlu1 receptor was established and a putative binding mode within the receptor's transmembrane domain was visualized.

• A significant substituent effect on the regioselectivity in addition of alkynes to 3-substituted pyridines
  作者：Shinji Yamada、Aya Toshimitsu、Yasuko Takahashi

  日期：2009.3

  A substituent at the 3-position on a pyridine ring significantly affects the regioselectivity during the addition of alkynes to pyridinium salts. When the substituent is an electron-withdrawing group, 1,6-adducts are predominantly produced, whereas, 1,2-adducts become the major products when the substituent is an electron-donating group. The changes in the regioselectivity depending on the substituent

  吡啶环上3位的取代基会显着影响将炔烃加至吡啶鎓盐中的区域选择性。当取代基为吸电子基团时，主要产生1,6-加合物，而当取代基为给电子基团时，1,2-加合物成为主要产物。取决于取代基的区域选择性的变化可以通过产物稳定性的差异来解释。产生的二氢吡啶很容易与氯腈以定量产率芳香化为二取代的吡啶。

  A novel compound [Fe(PZDA)(H2O)2]·2H2O}n has been synthesized and its structure determined by X-ray diffraction analysis, which consists of a quasi-ladder-like double chain running along a axis where Fe(II) ions are linked through the carboxylic groups acting as the edges of the ladder and pyrazine rings functioning as the rungs. Variable-temperature magnetic susceptibility study indicates the presence of spin frustration in the double chain compound.
