Etifoxine hydrochloride是一个非苯二氮卓类的、具有 GABA 能的化合物,是GABAA受体亚基 α1β2γ2 和 α1β3γ2 的阳性变构调节剂。Etifoxine hydrochloride 在啮齿类动物中显示出抗焦虑和抗惊厥活性。
生物活性 | Etifoxine hydrochloride, a non-benzodiazepine GABAergic compound, is a positive allosteric modulator of α1β2γ2 and α1β3γ2 subunit-containingGABAAreceptors. Etifoxine hydrochloride reveals anxiolytic and anticonvulsant properties in rodents[1][2][3]. |
体外研究 (In Vitro) | Etifoxine (EFX), at concentrations ranging from 10 to 300 μM (higher concentrations limited its solubility), produces a dose-dependent increase in the [3H]muscimol binding at equilibrium, to 155±2% of its control value at 300 μM EFX[1].

体内研究 (In Vivo) | Etifoxine competitively inhibits [35S]TBPS binding with micromolar potency in rat brain[1]. Etifoxine (3.125-50 mg/kg) exhibits more pronounced anxiolytic and anticonvulsant effects in the BALB/cByJ mice compared to the C57BL/6J mice[3].
Animal Model: | Six-week old BALB/cByJ and C57BL/6J mice (20-25 g)[3]. | Dosage: | 3.125-50 mg/kg. | Administration: | Intraperitoneal inhection. | Result: | Significantly increased the amount of time spent on the open arms at the 12.5 mg/kg dose when compared to vehicle (p = 0.009) in BALB/cByJ mice but produced no effect in C57B/6J mice. BALB/cByJ mice compared with C57BL/6J mice exhibited significantly (p< 0.012) lower
plasma levels of the compound at 15 and 30 min.
