FG-7142

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]
