Benzodiazepine Ro 15-1788: electrophysiological evidence for partial agonist activity.
The effects of diazepam and Ro 15-1788 were assessed upon responses of mouse spinal cord (SC) neurons in cell culture to the amino acid neurotransmitters 4-aminobutyric acid (GABA) and S-glutamic acid. Diazepam (100 nM) enhanced GABA responses by 65 +/- 3% (113 cells), while Ro 15-1788 (100 nM) failed to alter GABA responses but reduced their enhancement by diazepam. Higher Ro 15-1788 concentra...
متن کاملThe anticonvulsant effect of the benzodiazepine antagonist, Ro 15-1788: an EEG study in 4 cases.
An EEG study was carried out in 4 epileptic patients. In each case, Ro 15-1788 caused the disappearance or marked reduction of the epileptic potentials. In 1 case the patient had been pretreated with diazepam; in the other cases there had been no prior benzodiazepine treatment. In the first case, it is possible that Ro 15-1788 acted by abolishing a paradoxical effect of diazepam; in the other c...
متن کاملInhibition of hypothermic effect of cholecystokinin by benzodiazepines and a benzodiazepine antagonist, Ro 15-1788, in mice.
Intracisternally administered cholecystokinin produced long lasting hypothermia in mice, and the hypothermic effect was significantly antagonized by benzodiazepines like chlordiazepoxide and diazepam and by a benzodiazepine antagonist, Ro 15-1788, that were administered intraperitoneally. Proglumide, a cholecystokinin antagonist, failed to prevent the hypothermia induced by cholecystokinin at a...
متن کاملDifferential effects of the benzodiazepine antagonist Ro 15-1788 after "general anaesthetic" doses of benzodiazepines in mice.
The effects of the benzodiazepine antagonist Ro 15-1788 20 mg kg-1 after "general anaesthetic" doses of several benzodiazepines were studied in mice, in order to determine if the effects of the latter were attributable to an action at benzodiazepine receptors. Male CDI mice were used and the end-points for anaesthesia were loss of the righting reflex and loss of the foot pinch reflex. The effec...
متن کاملThe direct enhancement of positive palatability by chlordiazepoxide is antagonized by Ro 15-1788 and CGS 8216.
In a previous study, it was found that positive, palatability-dependent consummatory reactions in rats to intraorally infused tastes were facilitated by chlordiazepoxide (10 mg/kg). In contrast, the rats' more neutral or aversive reactions to these tastes were not facilitated by chlordiazepoxide. This suggested that chlordiazepoxide might selectively enhance the positive palatability of tastes....
