Biochem/physiol Actions

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.

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

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

α5-containing GABAARs are potential therapeutic targets for clinical conditions including age-related dementia, stroke, schizophrenia, Down syndrome, anaesthetic-induced amnesia, anxiety and pain. α5-containing GABAARs are expressed in layer 5 cortical neurons and hippocampal pyramidal neurons where they mediate both tonic currents
