Abstract：
:We report that a subtoxic dose of the succinate dehydrogenase (SDH) inhibitor malonate greatly enhances the neurotoxicity of three different excitatory amino acid agonists: N-methyl-D-aspartate (NMDA), S-alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (S-AMPA), and L-glutamate. In male Sprague-Dawley rats, intrastriatal stereotaxic injection of malonate alone (0.6 mumol), NMDA alone (15 nmol), S-AMPA alone (1 nmol), or glutamate alone (0.6 mumol) produced negligible toxicity as assessed by measurement of lesion volume. Coinjection of subtoxic malonate with NMDA produced a large lesion (15.2 +/- 1.4 mm3), as did coinjection of malonate with S-AMPA (11.0 +/- 1.0 mm3) or glutamate (12.8 +/- 0.7 mm3). Administration of the noncompetitive NMDA antagonist MK-801 (5 mg/kg i.p.) completely blocked the toxicity of malonate plus NMDA (0.5 +/- 0.3 mm3). This dose of MK-801 had little effect on the lesion produced by malonate plus S-AMPA (9.0 +/- 0.7 mm3), but it attenuated the toxicity of malonate plus glutamate by approximately 40% (7.5 +/- 0.9 mm3). Coinjection of the AMPA antagonist 2,3-dihydroxy-6-nitro-7-sulfamoylbenzo(f)-quinoxaline (NBQX; 2 nmol) had no effect on malonate plus NMDA or malonate plus glutamate toxicity (12.3 +/- 1.8 and 14.0 +/- 0.9 mm3, respectively) but greatly attenuated malonate plus S-AMPA toxicity (1.5 +/- 0.9 mm3). Combination of the two antagonists conferred no additional neuroprotection in any paradigm. These results indicate that metabolic inhibition exacerbates both NMDA receptor- and non-NMDA receptor-mediated excitotoxicity.(ABSTRACT TRUNCATED AT 250 WORDS)
