CGS-20625 is an anxiolytic drug used in scientific research. It has similar effects to benzodiazepine drugs,[1] but is structurally distinct and so is classed as a nonbenzodiazepine anxiolytic.[2][3] It produces anxiolytic and anticonvulsant effects, but with no sedative effects even at high doses, and no significant muscle relaxant effects.[4] It is orally active in humans, but with relatively low bioavailability.[5]

CGS-20625 is a positive allosteric modulator at several GABAA receptors types. Due to its alicyclic moiety potency at γ1 subunit containing receptor types is more pronounced for CGS-20625 compared to benzodiazepines.[1] γ1 subunits are expressed at higher levels in the central amygdala.[6]
