  名称：

  Enzymatic oxidation of the dopaminergic neurotoxin, 1 (R), 2(N)-Dimethyl-6,7-Dihydroxy-l,2,3,4-Tetrahydroisoquinoline, into 1,2(N)-Dimethyl-6,7-Dihydroxyisoquinolinium ion

  摘要：

  The dopamine-derived alkaloid, 1(R),2(N)-dimethyl-6,7-dihydroxy-1,2,3,4 tetrahydroisoquinoline [N-methyl(R)salsolinol] was found to be oxidized enzymically into the more cytotoxic species, 1,2(N)-dimethyl-6,7-dihydroxyiso-quinolinium ion, using enzyme sample prepared from human brain cortex. The values of the Michaelis constant and of the maximum velocity were 912 mu M and 1368 pmol/min/mg protein, respectively. The enzyme was not inhibited by inhibitors of monoamine oxidase, but was sensitive to semicarbazide. The oxidation is discussed in relation to the dopaminergic neurotoxicity of N-methyl(R)salsolinol.
