Abstract: | 1 Ethylenediamine, 31.6-1000 mg/kg intraperitoneally, inhibited the convulsive effects of pentylenetetrazol, 100 mg/kg (i.p.) in mice. 2 Ethylenediamine, 100-1000 mg/kg (i.p.) increased the convulsion threshold to the intravenous infusion of three convulsants in the order pentylenetetrazol greater than bicuculline greater than strychnine. 3 The benzodiazepine antagonist R0 15-1788, 10 mg/kg (i.p.), significantly inhibited the anticonvulsant action of diazepam, 50 micrograms/kg, but not ethylenediamine, 1000 mg/kg. 4 These results clearly indicate that ethylenediamine has anticonvulsant properties and are consistent with the hypothesis that ethylenediamine is a gamma-aminobutyric acid (GABA)-mimetic. |
