| Description | Picrotoxinin is a blocker of chloride channel and a noncompetitive antagonist of GABAA with an IC50 of 1.15 μM for α1β2γ2L GABAA. Picrotoxinin shows convulsant properties. |
| In vitro | Picrotoxinin (1 nM-1 mM) dose-dependently inhibits the action of the GABAA receptor and inhibits etomidate, propofol, diazepam, thiopentone sodium, loreclezole and allopregnanolone with IC50s of 0.55 μM, 0.49 μM, 0.35 μM, 0.50 μM, 0.14 μM and 0.44 μM in the presence of EC5 GABA, respectively[1]. |
