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.

S J Cooper et al.
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

Life sciences, 44(4), 289-299 (1989-01-01)
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
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

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)
C Brown et al.
European journal of pharmacology, 103(1-2), 139-143 (1984-08-03)
The pyrazoloquinolinones CGS 9896, CGS 9895 and CGS 8216 potently displace the benzodiazepines from their CNS binding site in vitro but have been reported to display agonist, partial agonist and antagonist activity respectively in a number of in vivo tests
