There is increasing evidence that compounds with selectivity for gamma-aminobutyric acid(A) (GABA(A)) alpha 2- and/or alpha 3-subtypes may retain the desirable anxiolytic activity of nonselective benzodiazepines but possess an improved side effect profile. Herein we describe a novel series of GABA(A) alpha 2/alpha 3 subtype-selective agonists leading to the identification of the development candidate 17, a nonsedating anxiolytic in preclinical animal assays.
