摘要
Positive modulators at benzodiazepine sites of alpha 2- and alpha 3-containing GABA(A) receptors are believed to be anxiolytic. Negative allosteric modulators of alpha 5-containing GABA(A) receptors enhance cognition. By oocyte two-electrode voltage clamp and subsequent structure-activity relationship studies, we discovered cinnoline and quinoline derivatives that were both positive modulators at alpha 2-/alpha 3-containing GABA(A) receptors and negative modulators at alpha 5-containing GABA(A) receptors. In addition, these compounds showed no functional activity at alpha 1-containing GABA(A) receptors. Such dual functional modulators of GABA(A) receptors might be useful for treating comorbidity of anxiety and cognitive impairments in neurological and psychiatric illnesses. (C) 2010 Elsevier Ltd.
