| Bioactivity | (S)-Norzopiclone ((S)-N-Desmethyl zopiclone; SEP-174559) is a metabolite of Zopiclone with anxiolytic and anticonvulsant effects. (S)-Norzopiclone has benzodiazepine-like actions at γ2-bearing subtypes of the GABAA receptor and inhibits nACh and NMDA receptors[1]. |
| Invitro | Micromolar concentrations of (S)-Norzopiclone (SEP-174559) potentiates GABAA receptor currents evoked by subsaturating concentrations of GABA[1]. (S)-Norzopiclone9 is not selective between alpha1-, alpha2-, or alpha3-bearing GABAA receptors. Within the nicotinic receptor superfamily, (S)-Norzopiclone does not affect serotonin type-3 receptor function but is found to inhibit nACh receptors[1].In the glutamate receptor superfamily, (S)-Norzopiclone inhibits N-methyl-D-aspartate (NMDA) receptor currents but does not affect non-NMDA receptors[1]. |
