    Amyloidogenic proteins form aggregates in cells, thereby leading to neurodegenerative disorders, including Alzheimer's and prion's disease, amyotrophic lateral sclerosis (ALS) in humans, and degenerative myelopathy (DM) and cognitive dysfunction in dogs. Hence, many small-molecule compounds have been screened to examine their inhibitory effects on amyloidogenic protein aggregation. However, no effective drug suitable for transition to clinical use has been found. Here we examined several novel oxindole compounds (GIF compounds) for their inhibitory effects on aggregate formation of the canine mutant superoxide dismutase 1 (cSOD1 E40K), a causative mutation resulting in DM, using Thioflavin-T fluorescence. Most GIF compounds inhibited the aggregation of cSOD1 E40K. Among the compounds, GIF-0854-r and GIF-0890-r were most effective. Their inhibitory effects were also observed in cSOD1 E40K-transfected cells. Additionally, GIF-0890-r effectively inhibited the aggregate formation of human SOD1 G93A, a causative mutation of ALS. GIF-0827-r and GIF-0856-r also effectively inhibited aggregate formation of human prion protein (hPrP). Subsequently, the correlation between their inhibitory effects on cSOD1 and hPrP aggregation was shown, indicating GIF compounds inhibited the aggregate formation of multiple amyloidogenic proteins. Conclusively, the novel oxindole compounds (GIF-0827-r, GIF-0854-r, GIF-0856-r, and GIF-0890-r) are proposed as useful therapeutic candidates for amyloidogenic neurodegenerative disorders.

  • Metal distribution in Cu/Zn-superoxide dismutase revealed by native mass spectrometry

    　View Summary

    Cu/Zn-superoxide dismutase (SOD1) is a homodimer with two identical subunits, each of which binds a copper and zinc ion in the native state. In contrast to such a text book case, SOD1 proteins purified in vitro or even in vivo have been often reported to bind a non-stoichiometric amount of the metal ions. Nonetheless, it is difficult to probe how those metal ions are distributed in the two identical subunits. By utilizing native mass spectrometry, we showed here that addition of a sub-stoichiometric copper/zinc ion to SOD1 led to the formation of a homodimer with a stochastic combination of the subunits binding 0, 1, and even 2 metal ions. We also found that the homodimer was able to bind four copper or four zinc ions, implying the binding of a copper and zinc ion at the canonical zinc and copper site, respectively. Such ambiguity in the metal quota and selectivity could be avoided when an intra-subunit disulfide bond in SOD1 was reduced before addition of the metal ions. Apo-SOD1 in the disulfide-reduced state was monomeric and was found to bind only one zinc ion per monomer. By binding a zinc ion, the disulfide-reduced SOD1 became conformationally compact and acquired the ability to dimerize. Based upon the results in vitro, we describe the pathway in vivo enabling SOD1 to bind copper and zinc ions with high accuracy in their quota and selectivity. A failure of correct metallation in SOD1 will also be discussed in relation to amyotrophic lateral sclerosis.
