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.

GABAA receptors containing an alpha2 subunit are proposed to mediate the anxiolytic effect of benzodiazepines (BZ) based on studies in transgenic mice using unconditioned models of anxiety. Conditioned models of anxiety were not assessed and are rarely encountered in phenotyping

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

Spinal administration of GABA(A) receptor modulators, such as the benzodiazepine drug diazepam, partially alleviates neuropathic hypersensitivity that manifests as spontaneous pain, allodynia, and hyperalgesia. However, benzodiazepines are hindered by sedative impairments and other side effect issues occurring mainly as a
