Biochem./physiol. Wirkung

TB21007 is a gamma-aminobutyric acid type A receptor (GABAA) alpha 5 (α5) subtype-selective (αβ3γ2 Ki in nM = 1.6/α5, 20/α1, 16/α2, 20/α3) negative allosteric modulator (NAM)/inverse agonist (% inhibition at 100 nM = 51/α5, 21/α1, 1/α2, 3/α3, using L(tk-) fibroblast expressing β3γ2 with respective α subunit). TB21007 enhances cognitive performance in a hippocampal-dependent memory task in vivo (0.3 mg/kg i.p. in rats; delayed ‘matching-to-place′ Morris water maze test) without the convulsant or proconvulsant activity (3 mg/kg i.p. in mice) observed with nonselective inverse agonists.

Neurobiology of aging, 91, 1-4 (2020-04-03)
Numerous aging studies have identified a shift in the excitatory/inhibitory (E/I) balance with heightened hippocampal neural activity associated with age-related memory impairment across species, including rats, monkeys, and humans. Neurobiological investigations directed at the hippocampal formation have demonstrated that unimpaired

The role of spinal α5 subunit-containing GABAA (α5-GABAA) receptors in chronic pain is controversial. The purpose of this study was to investigate the participation of spinal α5-GABAA receptors in the reserpine-induced pain model. Reserpine administration induced tactile allodynia and muscle

Temporary neuronal inactivation of the ventral hippocampus with the GABAA agonist muscimol suppresses unconditioned fear behavior (anxiety) but inactivation of the dorsal hippocampus does not. On the other hand, inactivating the dorsal hippocampus disrupts fear memory, while inactivating the ventral

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 GABA(A) receptor ligands. These thiophenes have higher binding affinity for the GABA(A) alpha5 receptor subtype compared to

Neuropharmacology, 64, 145-152 (2012-06-27)
A condition of excess activity in the hippocampal formation is observed in the aging brain and in conditions that confer additional risk during aging for Alzheimer's disease. Compounds that act as positive allosteric modulators at GABA(A) α5 receptors might be
