CGS-9896 is an anxiolytic drug used in scientific research. It has similar effects to benzodiazepine drugs but is structurally distinct and so is classed as a nonbenzodiazepine anxiolytic.[1]

CGS-9896 is a benzodiazepine receptor partial agonist which produces long-lasting anxiolytic and anticonvulsant effects in animal studies but does not produce sedative effects.[2][3] It also increases appetite,[4] and reduces the development of gastrointestinal ulcers following chronic stress.[5]
