The actions of etazolate (SQ20009) on cultured cortical neurons have been examined in electrophysiological experiments and in receptor binding studies. Etazolate (0.3 to 100 microM) prolongs the duration of spontaneously occurring IPSPs. Higher concentrations of etazolate produce an increase in

[35S]t-Butylbicyclophosphorothionate ([35S]TBPS), a bicyclic cage convulsant, binds to the anion gating mechanism of the GABA/benzodiazepine receptor chloride channel complex. Using a carefully calibrated radiation inactivation technique, the molecular weight of [35S]TBPS binding complexes from frozen rat cerebral cortex was estimated
