ZK-93423

ZK-93423 is an anxiolytic drug from the β-carboline family, closely related to abecarnil.^[1] It is a nonbenzodiazepine GABA_A agonist which is not subtype selective and stimulates α₁, α₂, α₃, and α₅-subunit containing GABA_A receptors equally.^[2] It has anticonvulsant, muscle relaxant and appetite stimulating properties comparable to benzodiazepine drugs.^[3][4][5][6] ZK-93423 has also been used as a base to develop new and improved beta-carboline derivatives and help map the binding site of the GABA_A receptor.^{[7][8][9][10][11][12]}
