    • Copper(II) perchlorate hexahydrate 98% and d-penicillamine were purchased from Sigma. Iron(II) sulfate heptahydrate, 2,2′-biquinoline, and cimetidine were purchased from Wako Pure Chemical (Osaka, Japan). 1,10-Phenanthroline monohydrate, 2,9-dimethyl-4,7-dimethyl-1,10-phenanthroline (bathocuproine), 2,9-1,10-phenanthroline (neocuproine), tetraphenylporphine (TPP), tetraphenylporphine tetrasulfonic acid (TPPS), α,β,γ,δ-tetrakis(1-methylpyridinium-4-yl)porphine p-toluenesulfonate (TMPyP), tetrakis(4-carboxyphenyl)porphine (TCPP), 2,2′-bicinchoninic acid dipotassium salt, 5-chloro-7-iodo-8-hydroxyquinoline (clioquinol), and 8-hydroxyquinoline were purchased from Tokyo Kasei (Tokyo, Japan). Manganese(III) tetrakis(1-methylpyridinium-4-yl)porphyrin pentachloride (Mn-TMPyP) and Mn(III)tetrakis(4-benzoic acid)porphyrin chloride(Mn-TCPP or Mn-TBAP) were purchased from Calbiochem (California, USA). They were dissolved in 100% dimethylsulfoxide (DMSO) or 95% ethanol just before use.

    • Two types of prion-infected mouse neuroblastoma (N2a) cell lines were used in this study: N2a cells infected with the RML strain (ScN2a) [16] and N2a#58 cells infected with the Fukuoka-1 strain (F3). N2a#58 cells are known to express five times more normal PrP than N2a cells. Both ScN2a cells and F3 cells were grown in six-well culture plates in Opti-MEM (Invitrogen) supplemented with 10% fetal bovine serum. The cells were allowed to reach confluence, and chemicals at various concentrations were added to the medium when 5% of the confluent cells were passaged.The final concentration of either DMSO or ethanol in the medium was less than 0.2%. The cultures were allowed to grow to confluence (3 or 4 days).

    • SOD-like assay kit-WST (Dojindo Chemical, Kumamoto, Japan) was used for the quantification of SOD-like activity. This method is a xanthine-based spectrophotometric assay using the tetrazolium salt WST-1. The SOD-like activity was evaluated using the standard curve of SOD-like activity versus absorbance at 450 nm. Differences of SOD-like activity were tested by use of the unpaired Student's t test, and p values smaller than 0.05 were considered to be statistically significant.
