Eleven beta-carbolinium compounds (beta C+s) and MPP+ were stereotaxically injected (40-200 nmol in 5 microliter of vehicle) unilaterally into the substantia nigra of anesthetized adult male Sprague-Dawley rats. The rats were sacrificed after three weeks. The ipsilateral striatum was analyzed for dopamine and DOPAC levels with HPLC. The brainstem injection(More)
N-Methylated beta-carbolinium compounds (N-Me-BCs), including 2-N-methyl and 2,9-N,N-dimethyl analogs, structural analogs of 1-methyl-4-phenylpyridinium (MPP+), may be endogenously bioactivated, MPP(+)-like toxins, capable of inducing parkinsonism. Both MPP+ and selected N-Me-BCs inhibit NADH-linked mitochondrial respiration (Complex I). We now show that(More)
