Abstract

Tonic-clonic convulsions of mutant quaking mice were antagonized by the intracerebroventricular injection of N-methyl-D-aspartate receptor antagonists. The competitive antagonists, CPP (3-((+/-)-2-carboxypiperazin-4-yl)-propyl-1-phosphonic acid) and CGS 19755 (cis-4-(phosphonomethyl)-2-piperidine carboxylic acid), exerted a partial anticonvulsant action, with ED50S of 0.115 and 0.076 nmol, respectively. The non-competitive antagonists, TCP (1-(1-(2-thienyl)cyclohexyl)piperidine) and MK-801 [+)-5-methyl-10,11-dihydro-5H-dibenzo(a,d)cyclohepten-5,10-imine), provided full protection, with ED50s of 4.49 and 2.67 nmol, respectively. The competitive antagonists elicited a marked ataxia whereas the non-competitive antagonists did not have side-effects. These results might reflect the involvement of glutamatergic neurotransmission in the convulsions of the quaking mutants.
