Oxidative stress induced by reactive oxygen and/or nitrogen species has been considered as a major cause of cellular injuries in a variety of neurodegenerative disorders including Alzheimer's disease (AD). Inflammatory as well as oxidative tissue damage has been implicated in pathophysiology of AD, and non-steroidal anti-inflammatory drugs have been reported to have beneficial effects in the treatment or prevention of AD.(omitted)

6-[2-(Benzoxazol-2-ylmethylamino)ethoxy]-1-alkyl-1H-indole-2-carboxylic acids were designed and synthesized as $\beta$-amyloid (A$\beta$) fibril assembly inhibitors. Their inhibitory activity on A$\beta$, aggregation was evaluated by thioflavin T assay although their activities were insignificant.

Excessive accumulation of beta-amyloid (A$\beta$) peptides is one of the leading hypotheses to explain neurodegenerative processes in Alzheimer's disease (AD). It has been suggested that $A\beta$ toxicity is associated with increases in reactive oxygen species. whose overproduction may in turn initiate neurotoxic events. (omitted)

Microglial cell can act for phagocytosis against abnormal particles in brain, which means that beta-amyloid produced from APP(amyloid precursor protein) can be phagocytosed by microglia when released. In contrast. when senile plaque has already been formed in brain cortex and hippocamphal region, microglia can also accelerate the AD pathogenesis due to chronic inflammatory action, which lead to neuron cell cytotoxicity.

beta-Amyloid (A$\beta$) peptide is the major component of senile plaques and considered to have a causal role in the development and progression of Alzheimer's disease. There has been compelling evidence supporting that $A\beta$-induced cytotoxicity is mediated through oxidative and/or nitrosative stress. Recently, considerable attention has been focused on dietary manipulation of oxidative and/or nitrosative damage. L-Egrothioneine (EGT) is a low-molecular weight naturally occurring thiol compound of dietary origin which exists in milimolar concentrations in the brain, liver, kindney, erythrocytes, ocular tissues and in seminal fluids of mammals.

Inflammatory as well as oxidative tissue damage has been associated with pathophysiology of Alzheimer's disease (AD), and nonsteroidal anti-inflammatory drugs have been shown to retard the progress of AD. In this study, we have investigated the molecular mechanisms underlying oxidative and inflammatory cell death induced by beta-amyloid (Abeta), a neurotoxic peptide associated with senile plaques formed in the brains of patients with AD, in cultured PC12 cells.
