The specific topic, "Isoquinolines And Beta-Carbolines As Neurotoxins And Neuroprotectants - New Perspectives In ParkinsonS Disease Therapy," was chosen in light of accumulating neurobiological evidence indicating that, in addition to exogenous neurotoxins (e.g., 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine MPTP]), endogenous compounds may play an important role in the most common neurodegenerative disorders (e.g., Parkinsons disease). Two groups of amine related compounds, which appeared chemically like MPTP, were detected in human brain and cerebrospinal fluid (CSF): -carbolines...
