- W2045704153 abstract "Metal ions associated with amyloid-β (Aβ) species have been suggested to be involved in neurodegeneration leading to the progression of Alzheimer's disease (AD). The role of metal-involved Aβ species in AD neuropathogenesis, however, is not fully elucidated. In order to advance this understanding and contribute to the therapeutic development for AD, the rational structure-based design of small molecules that specifically target metal ions surrounded by Aβ species has recently received increased attention. To date, only a few compounds have been fashioned for this purpose. Herein, we report the design strategy, synthesis, characterization, and reactivity of new bifunctional IMPY derivatives K1 and K2. Using UV-vis and high-resolution two-dimensional (2D) NMR spectroscopy, the bifunctionality of K1 and K2 (metal chelation and Aβ interaction) was confirmed. These bifunctional IMPY derivatives showed preferential reactivity toward metal-induced Aβ aggregation over metal-free conditions in both in vitro inhibition and disaggregation experiments. Taken together, this study provides another example of a bifunctional small molecule framework that can target metal ions associated with Aβ species." @default.
