Anticonvulsant activity of Mimosa pudica decoction.

The decoction of Mimosa pudica leaves given intraperitoneally at dose of 1000-4000 mg/kg protected mice against pentylentetrazol and strychnine-induced seizures. M. pudica had no effect against picrotoxin-induced seizures It also antagonized N-methyl-D-aspartate- induced turning behavior.

Anticonvulsant properties of the methanolic extract of Cyperus articulatus (Cyperaceae).

The methanolic extract of rhizomes of Cyperus articulatus, a plant used in traditional medicine in Africa and Latin America for many diseases, possesses anticonvulsant activity in mice. This extract protected mice against maximal electroshock (MES)- and pentylenetetrazol (PTZ)-induced seizures. It also delayed the onset of seizures induced by isonicotinic acid hydrazide and strongly antagonized N-methyl-D-aspartate-induced turning behavior.

The competitive NMDA receptor antagonists CGP 37849 and CGP 39551 are potent, orally-active anticonvulsants in rodents.

Anticonvulsant properties of CGP 37849 and CGP 39551, two novel phosphono-amino acids which are competitive NMDA receptor antagonists, were examined in rodents. At optimal pretreatment times CGP 37849 suppressed electroshock-induced seizures in mice and rats with ED50s ranging from 8 to 22 mg/kg after oral administration, and 0.4 to 2.
