Application

Ro 15-4513 has been used as a benzodiazepine (Bz) inverse agonist in rats and to test its binding with diazepam-sensitive (DS) receptors in in vitro radioligand binding studies.

Biochem/physiol Actions

Ro 15-4513 is benzodiazepine receptor partial inverse agonist. It elicits anxiogenic property and is an ethanol antagonist. It elicits a high affinity towards diazepam sensitive and insensitive sites in the cerebellar region. Ro 15-4513 possesses an imidazo ring and is an imidazobenzodiazepine.

Ethanol, at pharmacologically relevant concentrations of 20 to 100 mM, stimulates gamma-aminobutyric (GABA) receptor-mediated uptake of 36Cl-labeled chlorine into isolated brain vesicles. One drug that acts at GABA-benzodiazepine receptors, the imidazobenzodiazepine Ro15-4513, has been found to be a potent antagonist

GABAA receptor functions are dependent on subunit composition, and, through their activation, GABA can exert trophic actions in immature neurons. Although several sex differences in GABA-mediated responses are known to be dependent on gonadal hormones, few studies have dealt with

gamma-Aminobutyric acid(A) receptor gamma-subunits are important for benzodiazepine (BZD) binding and modulation of the gamma-aminobutyric acid-mediated Cl(-) current. Previously, by using gamma2/alpha1 chimeric subunits, we identified two domains of the gamma2-subunit, Lys-41-Trp-82 and Arg-114-Asp-161, that are, in conjunction, necessary and

Ethyl alcohol (ethanol) has many molecular targets in the nervous system, its potency at these sites being low compared to those of sedative drugs. This has made it difficult to discover ethanol's binding site(s). There are two putative binding sites

In order to better understand the antagonistic effects of the partial inverse agonist of benzodiazepine receptors, RO 15-4513, against the disinhibitory action of ethanol, we examined the effects of RO 15-4513 at a dose (2.0 mg/kg) that did not alter
