Thiazesim hydrochloride
Thiazesim hydrochloride is a CNS-penetrant GABAA receptor inhibitor, exerting anticonvulsant and antidepressant effects. Thiazesim hydrochloride depresses amygdala output, disrupts conditioned avoidance response in rats. Thiazesim hydrochloride can be used for the research of depression and epilepsy.

Biological Activity
Thiazesim (20 mg/kg; i.p.; daily prior to each acquisition or retention training session) hydrochloride significantly depresses conditioned avoidance response performance in rats during both acquisition and retention phases, without impairing motor escape responses or inducing state-dependent learning[4].
Thiazesim (5-40 mg/kg; i.p.; single dose) hydrochloride blocks all tested unlearned behaviors at nondebilitating doses in rats[5].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:Sprague-Dawley rats (male, 120 days old, 300-325 g, shock-induced defensive fighting model)[2]
-
Dosage:1.0; 3.0; 5.0; 10.0 mg/kg
-
Administration:i.p.
-
Result:Recorded mean attacks of 40.00 at 1.0 mg/kg, 35.80 at 3.0 mg/kg, 41.80 at 5.0 mg/kg, and 23.60 at 10.0 mg/kg.
Produced no significant reduction in shock-induced defensive fighting compared to saline or baseline conditions.

-
Animal Model:Holtzman albino rats (male, 275 g)[4]
-
Dosage:20 mg/kg
-
Administration:i.p.; daily prior to each acquisition or retention training session
-
Result:Required a significantly higher mean number of trials to reach criterion.
Showed greater variability in trials to criterion.
Had a mean percent CAR during acquisition of 33.1% vs. 39.6% for controls, with significantly higher variance in the drug group.
Did not show significant differences in CAR latency or escape latency compared to controls.
Had a significantly lower mean percent CAR during retention compared to saline-treated rats.
Had significantly lower mean percent savings scores during retention compared to saline-treated rats.
Showed higher mean trials to criterion during retention, though this effect was not statistically significant.
Did not show significant differences in CAR latency during retention compared to controls.

Animal Model:Sprague-Dawley male rats (200-350 g)[5]
-
Dosage:5, 10, 20, 40 mg/kg
-
Administration:i.p.; single dose
-
Result:Caused dose-dependent decrease in forced motor activity, with ED50 of 43.89 mg/kg and no 50% reduction at 40 mg/kg.
Produced linear dose-dependent decrease in spontaneous motor activity, with ED50 of 29.88 mg/kg.
Induced linear dose-dependent decrease in weight-adjusted food consumption, with ED50 of 20.56 mg/kg.
Led to linear dose-dependent decrease in water consumption lick counts, with ED50 of 21.33 mg/kg.
Caused linear dose-dependent decrease in mouse-killing behavior, with ED50 of 33.30 mg/kg and no restoration of killing at 40 mg/kg via arousal.
Produced linear dose-dependent decrease in self-grooming time, with ED50 of 32.10 mg/kg.
Showed ED50 for conditioned avoidance response greater than the maximum tested dose of 40 mg/kg.
