  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.
