Disturbed metal ion homeostasis in conjunction with amyloid-β (Aβ) aggregation in the brain has been implicated in Alzheimer’s disease (AD) pathogenesis. To uncover the interplay between metal ions and Aβ peptides, multifunctional small molecules have been employed to monitor Aβ aggregation and toxicity in vitro. Naturally occurring flavonoids have emerged as a valuable class of compounds for this purpose due to their ability to modulate both metal-free and metal-induced Aβ aggregation leading to non-toxic amorphous peptide products; however, the structural moieties of flavonoids responsible for such reactivity have not been fully identified. Herein, we designed, synthesized, and characterized a set of synthetic flavonoids that interact with metal ions and Aβ species, modulate metal-free Aβ and metal?Aβ aggregation in vitro, and regulate toxicity induced by metal-free Aβ/metal?Aβ. Overall, through our studies we obtained valuable insights on the requirements for parity among metal chelation, intermolecular interactions, and substituent variation using synthetic flavonoids, which offer a basic fundamental understanding of a structure-interactionreactivity relationship between metal-free Aβ and metal?Aβ species with the flavonoid family.
