![]() ![]() Although the pathologic mechanisms of AD are not clearly elucidated, the pathologic hallmarks of AD are considered as the accumulation of beta-amyloid (Aβ) proteins in the form of senile plaques, the entanglement of hyperphosphorylated tau proteins in the form of neurofibrillary tangles, and loss of specific neurons. Alzheimer’s disease (AD), which accounts for 60–70% of dementia in the elderly, is one type of neurodegenerative disease, and the representative symptom of AD is cognitive decline. It is predicted that 1 out of 85 people will develop dementia by the year 2050. glyptostroboides and isolated five compounds have a potential for further study to be developed as anti-AD agents.Īs the proportion of the elderly population increases, dementia, which exhibits various cognitive impairments, becomes an important social and economic problem. Among the five compounds, sandaracopimarinol ( 4) and sandaracopimaradien-19-ol ( 5) were the most effective. Furthermore, the inhibition of Aβ aggregation by the compounds protected PC12 cells from Aβ aggregate-induced toxicity. All the compounds significantly reduced the aggregation of Aβ and enhanced the disaggregation of pre-formed Aβ aggregates in a dose-dependent manner. As a result, five compounds were isolated and elucidated as taxoquinone ( 1), sugiol ( 2), suginal ( 3), sandaracopimarinol ( 4), and sandaracopimaradien-19-ol ( 5) by comparing NMR data with references. The solvent-partitioned ethyl acetate layer was further separated based on the bioassay-guided isolation method combined with the ThT assay. ![]() The ethanol extract of Metasequoia glyptostroboides Hu & Cheng fruits (Cupressaceae) significantly reduced the aggregation of Aβ into oligomers and fibrils determined by Thioflavin T (ThT) assay. Thus, the purpose of this study is to find natural products that can reduce Aβ accumulation. The accumulation of beta-amyloid (Aβ), along with oxidative stress-inducing neurocellular apoptosis, has been considered one of the causes of AD.
