  选择性口服活性γ-氨基丁酸A alpha5受体反向激动剂作为认知增强剂。

  摘要：

  γ-氨基丁酸（A）（GABA-A）苯并二氮杂卓结合位点的非选择性反向激动剂对动物具有认知增强作用，但会产生焦虑，并可能引起惊厥。在这里，我们描述了新颖的GABA-A alpha5亚型反向激动剂，可将16鉴定为一种口服活性，功能选择性的化合物，可增强动物的认知度，而无产生焦虑或惊厥的作用。这种类型的化合物可用于对症治疗与阿尔茨海默氏病和相关痴呆有关的记忆障碍。

  Agonist lead identification for the high affinity niacin receptor GPR109a

  摘要：

  A strategy for lead identification of new agonists of GPR109a, starting from known compounds shown to activate the receptor, is described. Early compound triage led to the formulation of a binding hypothesis and eventually to our focus on a series of pyrazole acid derivatives. Further elaboration of these compounds provided a series of 5,5-fused pyrazoles to be used as lead compounds for further optimization. (C) 2007 Elsevier Ltd. All rights reserved.
