title: In vivo dopaminergic neurotoxicity of the 2-beta-methylcarbolinium ion, a potential endogenous MPP+ analog.
abstract: The MPP+-like neurotoxicity of the 2-methyl-beta-carbolinium species, a possible endogenous condensation product structurally related to MPP+, has been assessed by an intracerebral microdialysis technique. Although much less potent, this compound appears to cause the selective and irreversible destruction of nigrostriatal nerve terminals in rat brain in a manner similar to that observed under comparable conditions with MPP+.
