Ethylenediamine, 31.6–1000 mg/kg intraperitoneally, inhibited the convulsive effects of pentylenetetrazol, 100 mg/kg (i.p.) in mice.

Ethylenediamine, 100–1000 mg/kg (i.p.) increased the convulsion threshold to the intravenous infusion of three convulsants in the order pentylenetetrazol > bicuculline > strychnine.

The benzodiazepine antagonist Ro15–1788, 10 mg/kg (i.p.), significantly inhibited the anticonvulsant action of diazepam, 50 μg/kg, but not ethylenediamine, 1000 mg/kg.

These results clearly indicate that ethylenediamine has anticonvulsant properties and are consistent with the hypothesis that ethylenediamine is a γ‐aminobutyric acid (GABA)‐mimetic.
