| Description | Golexanolone (Golexanolona) is a novel GABA-A receptor-modulating steroid antagonist that reduces peripheral inflammation and neuroinflammation and improves cognitive and motor function in rats with chronic hyperammonemia, and may be used to study hepatic encephalopathy. |
| In vitro | In the absence of agonist (i.e., GABA, 0), the THDOC-mediated outward current excursion was significantly reduced when Golexanolone(GR3027) concentration was incrementally increased (0.03-3 µM, Fig. 2A), with an IC50 = 344 nM and Imax -33%. In addition, analysis of the AUC and peak current amplitude of the GABA-mediated response showed a concentration-dependent decrease in both parameters (IC50 = 341 nM, Imax -35% for AUC; IC50 = 563 nM, Imax -37% for peak current amplitude; n = 4-14, 95% confidence intervals;) The data suggest that the effects of Golexanolone(GR3027) on the THDOC-mediated α5β3γ2L GABAA channel activation.[2] |
| In vivo | In a toxicity study using doses of 50 and 100 mg/kg/day to evaluate oral administration of Golexanolone(GR3027) in rats, no toxicity was observed at 100 mg/kg/day.[1] |
