  Identification of a Novel, Selective GABA_A α5 Receptor Inverse Agonist Which Enhances Cognition

  摘要：

  In pursuit of a GABA(A) alpha5-subtype-selective inverse agonist to enhance cognition, a series of 6,7-dihydro-2-benzothiophen-4(5H)-ones has been identified as a novel class of GABAA receptor ligands. These thiophenes have higher binding affinity for the GABA(A) alpha(5) receptor subtype compared to the GABA(A) alpha(1), alpha(2), and alpha(3) subtypes, and several analogues exhibit high GABA(A) (alpha(5) receptor inverse agonism. 6,6-Dimethyl-3-(2-hydroxyethyl)thio-1-(thiazol-2-yl)-6,7-dihydro2-benzothiophen-4(5H)-one (43) has been identified as a full inverse agonist at the GABA(A) alpha5 receptor and is functionally selective over the other major GABA(A) receptor subtypes. 43 readily penetrates into the CNS to give selective occupancy of GABA(A) alpha5 receptors. In addition, 43 enhances cognitive performance in rats in the delayed 'matching-to-place' Morris water maze test-a hippocampal-dependent memory task-without the convulsant or proconvulsant activity associated with nonselective, GABA(A) receptor inverse agonists.

  高效，选择性和口服可生物利用的富含亮氨酸的重复激酶2（LRRK2）抑制剂

  摘要：

  最近，家族性帕金森氏病病例与富含亮氨酸的重复激酶2（LRRK2）基因有关。已经假设LRRK2蛋白的抑制可能具有改变疾病发病机理的潜力。从内部默克样品收集的高通量筛选中鉴定出了有效的，选择性的，口服生物利用的LRRK2抑制剂的二氢苯并噻吩系列。最初围绕核心进行的SAR研究将该系列确立为可治疗帕金森氏病的LRRK2抑制剂的易处理小分子先导系列。还发现将内酰胺掺入核心中大大改善了这些小分子的CNS和DMPK特性。

  Nonselective inverse agonists at the benzodiazepine binding site on the GABA-A chloride ion channel enhance cognitive performance in animals but cannot be used in the treatment of cognitive disorders because of anxiogenic and convulsant side effects. We have identified a novel series of GABA-A alpha5 receptor ligands during our search for alpha5 receptor inverse agonists as potential cognition enhancers. In particular, 6,6-dimethyl-3-(2-hydroxyethyl)thio-1-(thiazol-2-yl)-6,7-dihydro- 2-benzothiophen-4(5H-)-one (26) has been identified as a functionally selective GABA-A alpha5 inverse agonist.
