Screening of the Merck compound collection identified 6 as an unusually simple, low molecular weight hit with moderate affinity for GABA(A) receptors. The structural novelty of 6, compared to our advanced series of GABA(A) alpha 5 inverse agonists, made it an attractive molecule for further exploration. This paper will describe the evolution of 6 into a new series of ligands with nanomolar affinity and functional selectivity for GABA(A) alpha 5 receptor subtypes.
