SB-205,384 is an anxiolytic drug. It has similar effects to benzodiazepine drugs, but is structurally distinct and so is classed as a nonbenzodiazepine anxiolytic.

SB-205,384 is a GABAA positive allosteric modulator, which binds preferentially to α3, α5, and α6 subunit containing subtypes.[1][2] It has a novel mechanism of action, prolonging the duration of GABA-mediated chloride flux but without increasing the intensity of the response, and this may give it an unusual pharmacological profile,[3] with tests showing that it alters the firing of some populations of neurons while leaving others unaffected.[4] Animal studies have shown it to produce both anxiolytic and anti-aggressive effects, but with little sedation or other behavioural changes.[5][6]
