  Design and optimization of purine derivatives as in vivo active PDE10A inhibitors

  摘要：

  Phosphodiesterases are important enzymes regulating signal transduction mediated by second messenger molecules cAMP or cGMP. PDE10A is a unique member in the PDE family because of its selective expression in medium spiny neurons. It is recognized as anti-psychotic drug target. Based on the structural similarity between our previous chemistry work on 8-aminoimidazo[1,2-alpyrazines and the PDE10A inhibitors reported by Bartolome-Nebreda et al., we initialized a project for developing PDE10A inhibitors. After several rounds of optimization, we were able to obtain a few compounds with good PDE10A enzymatic activity. And after further PDE enzymatic selectivity study, metabolic stability assay and in vivo pharmacological tests we identified two inhibitors as interesting lead compounds with the potential for further PDE10A lead optimizatioin.

  6,8-二氯嘌呤与苯基硼酸和甲基氯化镁的区域选择性交叉偶联反应中的二分法：6,8-二取代嘌呤的合成

  摘要：

  Pd催化的6,8-二氯-9-(四氢吡喃-2-基)嘌呤与1当量苯基硼酸的交叉偶联反应区域选择性地进行，得到8-氯-6-苯基嘌呤，而类似的Fe催化反应与甲基氯化镁得到6-氯-8-甲基嘌呤衍生物作为主要产物。两种类型的单氯嘌呤中间体都经过其他交叉偶联反应或亲核取代，得到 9-(四氢吡喃-2-基)-6,8-二取代的嘌呤，这些嘌呤很容易脱保护为 8-取代的 6-苯基嘌呤或 6-取代的嘌呤8-甲基嘌呤。与苄基氯化镁和苯基溴化镁进行的类似反应得到了低转化率和低选择性。
