Title: [THE STUDY OF ANXIOLYTIC PROPERTIES OF NEW PYRAZOLO[C]PYRIDINE DERIVATIVE GIZH-72].
Abstract: It was studied the anxiolytic properties of 4,6-dimethyl-2-(4-chlorophenyl)-2,3-dihydro-1Í-pyrazolo[4,3-c]pyridin-3-one chloralhydrate (GIZh-72, 20 mg/kg, i.p.) and afobazole (1 mg/kg, i.p.) in comparison to fluoxetine (20 mg/kg, i.p.) and diazepam (1 mg/kg, i.p.) in open-field and marble burying tests on male mice of inbred strains BALB/C and C57BL/6. It is established that GIZh-72 administered both 30 min and 24 h before testing produces anxiolytic effect in the open-field test. The open field anxiety response patterns following GIZh-72 administration differed from these in diazepam or afobazole treated BALB/C mice. This drug also decreased the number of buried marbles in both BALB/C and C57BL/6 mice, the effect being comparable to that of afobazole and fluoxetine. In operant drug discrimination liquid-reinforcement paradigm in male Wistar rats, GIZh-72 failed to antagonize or substitute for the interoceptive stimulus cues of pentylenetetrazole evoking the saline-like responses in the latter case, which was evidence for the absence of properties of a ligand bearing positive modulator sites of GABA-A receptor.
