一般描述
Bretazenil, a tetracyclic imidazocarboxylic ester, is an anxi-olytic/anticonvulsant agent. It possesses a half-life of 2.5 hours and is quickly absorbed.
应用
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.
生化/生理作用
Bretazenil is a benzodiazepine partial agonist.
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.

1. A histidine residue in the N-terminal extracellular region of alpha 1,2,3,5 subunits of the human GABA(A) receptor, which is replaced by an arginine in alpha 4 and alpha 6 subunits, is a major determinant for high affinity binding of

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.

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

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

Benzodiazepine receptor partial agonists manifest full efficacy in preclinical tests of anxiolytic drug action but do not fully reproduce the discriminative stimulus effects of benzodiazepine receptor full agonists in pigeons. The partial agonist, bretazenil, binds to both diazepam-sensitive and diazepam-insensitive
