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.

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

Obesity-related diseases such as diabetes and dyslipidemia result from metabolic alterations including the defective conversion, storage and utilization of nutrients, but the central mechanisms that regulate this process of nutrient partitioning remain elusive. As positive regulators of feeding behaviour, agouti-related
