Biochem/physiol Actions

CGS 9895 is a GABA antagonist that acts via the benzodiazepine binding site of ag containing GABA receptors. CGS 9895 is the only known compound that can specifically enhance GABA-induced currents in ab subunit containing receptors, and acts at the extracellular a1+b3- subunit interface.

Rats were trained to respond under 3-min fixed-interval schedules of food presentation, and effects of the benzodiazepine-receptor ligands, flumazenil, 2-(4-methoxy-phenyl)-pyrazolo[4,3-c]quinolin-3(5H)-one (CGS 9895), 3-carbo-t-butoxy-beta-carboline (beta-CCtB), and beta-carboline-3-carboxylic acid ethyl ester (beta-CCE) were assessed before and after the induction of tolerance to

Physiology & behavior, 41(3), 247-255 (1987-01-01)
Several categories of compounds active at benzodiazepine receptors (BZR) in the brain have been distinguished: agonists, antagonists and the novel category of inverse agonist. In terms of their effects on ingestional responses (e.g., food, saline and water consumption), agonists increase
H E Shannon et al.
European journal of pharmacology, 92(1-2), 155-157 (1983-08-19)
The diazepam-like agonist and diazepam antagonist properties of the pyrazoloquinoline benzodiazepine receptor ligands CGS8216, CGS9895 and CGS9896 were evaluated in rats trained to discriminate between saline and 1.0 mg/kg of diazepam in a two-choice, discrete-trial procedure. None of the three

Physiology & behavior, 41(3), 241-245 (1987-01-01)
Five compounds that bind to the benzodiazepine (BZ) receptor, but show different pharmacological characteristics from the classical BZs, are profiled. CGS 8216 is a BZ antagonist/inverse agonist that reverses the effects of diazepam and also acts as a proconvulsant. CGS

Psychopharmacology, 89(4), 462-466 (1986-01-01)
Non-deprived male rats were familiarized with a highly palatable diet until baseline consumption in a 30-min daily access period had stabilised. Stereospecificity of the hyperphagic effect of benzodiazepine receptor agonists was demonstrated using two enantiomers, the (S)-enantiomer being Ro11-3128 (methylclonazepam)
