General description
Bretazenil, a tetracyclic imidazocarboxylic ester, is an anxi-olytic/anticonvulsant agent. It possesses a half-life of 2.5 hours and is quickly absorbed.
Application
Bretazenil has been used to determine non-specific binding due to its affinity to bind to a variety of γ-aminobutyric acid type A (GABAA) receptor subtypes (α1-3;5). It has also been used as a GABAA receptor partial agonist in the subcutaneous Alzet minipumps to treat obese agouti?related protein (AgRP)?ablated and lean naive mice to study its effect on them.
Biochem/physiol Actions
Bretazenil is capable of binding to γ-aminobutyric acid type A (GABAA) receptors that are sensitive and insensitive to diazepam. This compound possesses negligible sedative or muscle relaxant effects.
Bretazenil is a benzodiazepine partial agonist.

Benzodiazepines remain widely used for the treatment of anxiety disorders despite a side-effect profile that includes sedation, myorelaxation, amnesia, and ataxia, and the potential for abuse. gamma-Aminobutyric acid(A) (GABA(A)) receptor partial agonists, subtype-selective agents, and compounds combining both of these

Previous research suggests that intrinsic efficacy of benzodiazepines is an important determinant of their behavioral effects. We evaluated the reinforcing effects of the benzodiazepine partial agonist bretazenil using behavioral economic models referred to as "consumer demand" and "labor supply". Four

The pharmacokinetic and pharmacodynamic interactions of ethanol with the full benzodiazepine agonist midazolam, the partial agonist bretazenil and the benzodiazepine BZ1 receptor subtype selective agonist zolpidem have been determined in the rat in vivo, using an integrated pharmacokinetic-pharmacodynamic approach. Ethanol

The mouse rotarod test of motor coordination/sedation is commonly used to predict clinical sedation caused by novel drugs. However, past experience suggests that it lacks the desired degree of sensitivity to be predictive of effects in humans. For example, the

Epilepsia, 42(3), 337-344 (2001-07-10)
Perimenstrual catamenial epilepsy may in part be due to withdrawal of the endogenous progesterone-derived neurosteroid allopregnanolone that potentiates gamma-aminobutyric acidA (GABA(A)) receptor-mediated inhibition. Here we sought to determine whether the anticonvulsant potencies of neuroactive steroids, benzodiazepines, phenobarbital (PB), and valproate
