FG-7142 (ZK-31906) is a drug which acts as a partial inverse agonist at the benzodiazepine allosteric site of the GABA_A receptor.^[1] It has anorectic,^[2] anxiogenic and pro-convulsant effects.^[3] It also increases release of acetylcholine and noradrenaline,^[4] and improves memory retention in animal studies.^[5]
