  New Tetracyclic Derivatives of Imidazo[1,5-a][1,4]benzodiazepines and of Imidazo[1,5-a]-thieno[3,2-f][1,4]-diazepines

  摘要：

  The synthesis of new tetracyclic 1,4-diazepine derivatives is described. In these compounds, an additional five-membered heterocycle is fused on the known tricyclic ring systems imidazo[1,5-a][1,4]benzodiazepine and imidazo[1,5-a]thieno[3,2-f][1,4]diazepine. Many of these new compounds display a very high affinity to the benzodiazepine receptor in mammals.

  Through iterative design cycles we have discovered a number of novel new classes where the imidazo[1,5-a][1,2,4]-triazolo[1,5-d][1,4]benzodiazepine was deemed the most promising GABAA α5 inverse agonist class with potential for cognitive enhancement. This class combines a modest subtype binding selectivity with inverse agonism and has the most favourable molecular properties for further lead optimisation

  通过迭代设计周期，我们发现了许多新颖的新类，其中咪唑并[1,5- a ] [1,2,4]-三唑并[1,5- d ] [1,4]苯并二氮杂被认为是最有前途的GABA一个α5反相激动剂类的认知提高的潜力。此类具有适度的亚型结合选择性和反向激动作用，并具有最有利的分子特性，可进一步优化针对中枢神经系统（CNS）的药物。
