NS-2710 (LS-193,970) is an anxiolytic drug with a novel chemical structure, developed by the small pharmaceutical company Neurosearch. It has similar effects to benzodiazepine drugs, but is structurally distinct and so is classed as a nonbenzodiazepine anxiolytic. NS-2710 is a potent but non-selective partial agonist at GABA_A receptors, although with little efficacy at the α1 subtype and more at α2 and α3. It has anxiolytic effects comparable to chlordiazepoxide,^[1] and while it is a less potent anticonvulsant than the related drug NS-2664, it has a much longer duration of action, and similarly to other α2/α3-preferring partial agonists produces little sedative effects or physical dependence.^[2]
