CGS-20625 is an anxiolytic drug used in scientific research. It has similar effects to, and binds to the same target as benzodiazepine drugs,[1] but is structurally distinct and so is classed as a nonbenzodiazepine anxiolytic.[2][3]

CGS-20625 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]
