Attenuated amyloid-beta aggregation and neurotoxicity owing to methionine oxidation.

Aggregation of the amyloid-beta (Abeta) peptide into amyloid plaques is a characteristic feature of Alzheimer's disease neuropathogenesis. We and others have previously demonstrated delayed Abeta aggregation as a consequence of oxidizing a single methionine residue at position 35 (Met-35). Here, we examined the consequences of Met-35 oxidation on the extremely aggregation-prone peptides Abeta1-...

Effect of methionine-35 oxidation on the aggregation of amyloid-β peptide

Aggregation of Aβ peptides into amyloid plaques is considered to trigger the Alzheimer's disease (AD), however the mechanism behind the AD onset has remained elusive. It is assumed that the insoluble Aβ aggregates enhance oxidative stress (OS) by generating free radicals with the assistance of bound copper ions. The aim of our study was to establish the role of Met35 residue in the oxidation an...

Oxidation of Methionine-35 in Alzheimer’s amyloid-beta peptide and the aggregation of the oxidized peptide

MicroRNAs (miRNAs) are short, 22–25 nucleotide long transcripts that may suppress entire signaling pathways by interacting with the 3’-untranslated region (3’-UTR) of coding mRNA targets, interrupting translation and inducing degradation of these targets. The long 3’-UTRs of brain transcripts compared to other tissues predict important roles for brain miRNAs. Supporting this notion, we found th...

Synthesis and biological assessment of 2-hydroxyiminoethanones as anti-inflammatory and β-amyloid aggregation inhibitors

Alzheimer’s disease (AD) is a neuroinflammatory based pathologic state in which β-amyloid aggregates are a major devastating agents. In this study, a series of 2-hydroxyiminoethanones were synthesized and evaluated as anti-inflammatory in carrageenan and formalin tests and inhibitors of β-amyloid aggregation. Compounds 1-10b were synthesized through a two-step reaction. Results: Compounds 1-5b ...
