Fighting fire with fire: remodeling Aβ aggregation with H-aggregates of a europium(III) complex

Dalton Trans. 2024 Sep 18;53(36):14966-14970. doi: 10.1039/d4dt02188f.

Abstract

We herein report a "Fight Aggregation with Aggregation" (FAA) approach for redirection of amyloid-β peptide (Aβ) aggregation using a europium(III) complex (EuL3) that can undergo H-aggregation in aqueous solution under physiological conditions. The H-aggregates of EuL3 may serve as scaffolds that can facilitate the accumulation of Aβ to form non-fibrillar co-assemblies. As a result, the Aβ aggregation-induced cytotoxicity was inhibited.
