Abstract:

Inhibition of beta-amyloid (A beta) accumulation and A beta fibril (fA beta) formation from A beta are attractive therapeutic targets for the treatment of Alzheimer's disease (AD). While previous studies have shown anti-amyloidogenic effects of curcumin in vitro and in vivo, no studies have examined optimized turmeric extracts enriched in curcuminoids or turmerones. Three standardized turmeric extracts, HSS-838, HSS-848, and HSS-888, were prepared with different chemical profiles to investigate their potential therapeutic benefits for AD. These extracts were fingerprinted by DART TOF-MS to reveal the significant chemical complexity. In addition four curcuminoids (curcumin, tetrahydrocurcumin, demethoxycurcumin and bisdemethoxycurcumin) were also examined. We measured the effects of the extracts and curcuminoids, on the aggregation of A beta by using a thioflavin T cell-free assay and the secretion of A beta from human neuronal cells (SweAPP N2A cells) in vitro. All three extracts and the curcuminoids showed dose-dependent inhibition of fA beta aggregation from A beta(1-42) in the cell-free assay, with IC(50) values of
