GABAAreceptor agonist 2 (compound 4c) is a highly potent GABAAreceptor agonist which exhibits anti-depressive properties in classical mouse models of depression, such as the FST and TST. By binding to the GABA binding site on the GABAAreceptor, GABAAreceptor agonist 2 produces GABAergic effects. Notably, Compound 4c holds promise for depression research [1].
TPA-023B is an orally active and high-affinity agonist of the GABAAreceptor α2 α3 subtype (Kis: 0.73 nM 2 nM) partial and an antagonist α1 subtype (Ki: 1.8 nM), has non-sedating anxiolytic-like properties.
ZK93423 is a potent agonist of benzodiazepine receptor (IC50 = 1 nM) with non-selective between α1-, α2-, α3- and α5-subunit containing GABAAreceptors, Ki values are 4.1, 4.2, 6 and 4.5 nM for inhibition of [3H]Ro15-1788 binding to human recombinant α1β3
