| Bioactivity | Gaboxadol hydrochloride (Lu 02-030 hydrochloride) is a potent agonist of the GABAA receptor and an antagonist of GABAC receptors (IC50=25 μM). Gaboxadol hydrochloride displays a partial agonist efficacy on subunit α1β2γ2 with an ED50 value of 143 µM, a full agonist efficacy at α5 subunit (ED50=28-129 µM) and a superagonist efficacy at α4β3δ (ED50=6 µM). Gaboxadol hydrochloride is a non-opioid agent[1][2]. |
| Target | GABAA receptor; GABAC receptor |
| Invitro | Gaboxadol hydrochloride (0.34, 3.5 and 7.0 μM) decreses permeability across Caco-2 cell monolayers with a dose dependent manner, shows the mean Papp values with 8.1 × 10-6 cm·s-1, 6.1 × 10-1 cm·s-6 and 5.6 × 10-6 cm·s-1 for 0.34, 3.5 and 7 μM gaboxadol, respectively[3]. |
| In Vivo | Gaboxadol hydrochloride (intraperitoneal injection; 0.5, 1, 1.5, 2, 3, 4, or 5 mg/kg; once daily; three-day interval) normalizes the distance traveled by Fmr1 KO2 mice to WT activity levels at 0.5 mg/kg, additionally, this compound has no effect on locomotor activity in Fmr1 KO2 mice[2].
